How indoor air quality and health related?

Indoor air quality, also known as IAQ, has more impact on our daily lives than many people realize. Several aspects that affect our indoor air quality. What can be done to improve the situations that are subjected to them? Indoor air quality is the air quality around and within commercial buildings, residential structures, and other structures. When the air quality is heavily contaminated, it affects the health of those in and around it by breathing in these contaminants with the air.

Why Is how indoor air quality affects your health important?

Our overall comfort, health, and well-being is affected by indoor air quality, and when it is of poor quality, it can reduce our productivity at work and has been proven to affect children’s learning ability in school. It can be hard to believe that something we take for granted every day can have such an effect on our daily lives.

Which is the most important indoor air pollutant?

Many things that affect the indoor air quality, it can all depend on the environment around a structure. From carbon monoxide, microbial contaminants such as bacteria and mold, to radon, and volatile organic compounds, they all have a part in indoor air pollutant. Any energy stressor or mass can bring about antagonistic health conditions.

What are the 4 major indoor air pollutants?

  • Carbon Monoxide: An invisible and odorless gas comes from fossil fuels and produced by incomplete combustion.  
  • Radon: A colorless and odorless gas comes from the Earth in the form of uranium and is everywhere at low levels.
  • Nitrogen Dioxide: A corrosive and toxic gas, used in the medical industry.
  • Secondhand Smoke: Tobacco smoke that comes from burning tobacco products.

How do you check the air quality in your home?

Most of us overlook the air quality in our homes even though it is as much a safety issue as having locks on our door and smoke alarms in every bedroom.

Here, we offer some tips on how to check your home indoor air quality and advice on how to improve it:

  • Quality Monitor – There are several models at various prices on the market today that will effectively detect any issues of your home’s indoor air quality. These will typically check for allergens and dust particles, chemical pollutants, mold, and temperature.
  • Check for Mold – Some signs and symptoms that will tell you if your home has any mold infestation that. If you see signs of mold or if you notice a musty odor in your home, do a deep cleaning. If the odor or site of mold remains, a professional should be called to test and evaluate your home.
  • Carbon Monoxide Detectors – This device will detect the colorless, odorless, tasteless, and deadly gas. This byproduct often comes from appliances in your home, such as the cook stove, fireplace, furnace, grills, and water heater.
  • Radon Test Home Kit – Radon gas is a natural reaction of uranium breaking down and can be found in the soil around your home as well as in well water. It could infiltrate into your home, and an in-home test kit can detect if there is any in or around your home.
  • Air Purifier – These machines improve your home’s air quality and are very helpful for those with allergy or breathing problems. The most effective style is an electronic air purifier/air cleaner because they remove allergens and dust particles effectively, making the air cleaner to breath.
  • Change Air Filters Regularly – It is recommended to change your air filters once a month for homes with allergy suffers, every 3 months for the average household.

Why is air quality worse at night?

At night, cold air will settle to the ground because the sun isn’t heating the air. This creates a pollutant breeding ground as those pollutants accumulate. During daylight hours, the atmosphere is heated up the sun and expands. As the air expands, it takes the pollution up with it.

Is Indoor Air Quality and Asthma Related?

Asthma can be triggered by tobacco smoke aka secondhand smoke, along with dust mites and mold. Pest like cockroaches, mice, and other pests as well as indoor pets affect the indoor air quality and thus, trigger asthmatic symptoms.

Indoor Air Quality vs Outdoor – Which Is More Likely To Cause Issues?

This often surprises most people, but indoor air quality causes more issues than outdoor air quality. Indoor air concentrates harmful chemicals and other constituents that cause pollutants, whereas outdoors, those chemicals and constituents can spread out, even dissipate.

Why Is Indoor Air Quality In Homes More Important Than Elsewhere?

The EPA states that on the average, each person spends as much as 90% indoors, with over 60% of that being in our own home. Considering that the indoor air quality in our homes is 7 to 10 times more polluted than outside air, it only makes sense that the indoor air quality at home is the most important.

Basic Info. Regarding ACs

Your AC unit is an integral part of your home or business with its ability to keep the indoors of your property maintained with comfortable and stable temperatures.   As of such, when you require AC repair in the summer the need to have it fixed as soon as possible can be important in order for occupants to stay indoors with ease. When your AC is acting up the effects can be immediate or progress with outward signs through time. It’s important to notice if there are any changes in energy usage or increased energy bills as this can point to an improperly-working AC system. Certain issues can be fixed with simple measures while others may need the expertise of a professional technician that is certified with AC repair services.

How do you fix an air conditioner?

AC repair for home can vary depending on the issue at hand, oftentimes fixes can be made through maintenance adjustments with your AC. This can involve cleaning filters, checking the system’s coils, checking the proper amperage and voltage of your blower motor and many more tasks. Your AC can become vulnerable to changes from such factors as changing temperatures, energy efficiency, and productivity. As some areas of AC repair may incorporate electrical connections it’s important to reach out to a qualified and licensed technician for the job in order to avoid the risks and danger of being electrocuted. Other areas may even require expert eyes and access as such cases as ductwork needing to be updated can be tricky as they can differ in conditions throughout the property. As of such, such intricacies can be rather difficult for the average Joe or Jane to determine so it’s important to reach out for help when possible.  

AC Repair vs Replace

A big indicator that a repair or replacement service is necessary is when age comes into the equation. Certain parts and materials will have a max life span and afterward will start acting up if not replaced. When part of an AC system acts up os is not handled with prompt AC repair or replacement then you may see it affect the productivity of other parts. You may even cause other parts to prematurely age from being overworked or overheated. 

What is the reason for AC not cooling?

When your AC is not cooling it’s important to see what could be wrong with the thermostat first as it could be that the temperature simply needs to be set lower or that it’s not switched to the cooling mode. After this, if your AC unit is still continuing to blow warm air the next step is to assume that your refrigerant levels are low and need to be recharged. (A refrigerant recharge is just the technical term for it being refilled.) Other issues could be that there is a leak in the ducts or refrigerant areas which can lead to the refrigerant loss. This can cause another issue to develop as coils would freeze due to refrigerant leak exposure.

There are many signs that your AC will give you when you need either an AC repair or replace service. Your AC, for instance, can act differently depending on whether there has been excessive sun exposure, poor energy efficiency abilities, poor system design, insulation, ductwork or user operations. Such signs of a broken AC can include when your thermostat’s display is blank or has lost power, you’re hearing noises with your equipment or if there are water leaks in various areas. 

Why is my AC not working?

Know When To Conduct AC Repairs

Your AC system is an integral part of your home or business that will offer much needed cooling abilities during the summer months. It’s important to become familiar with the parts of your units like with your AC compressor because when the time comes around for AC repair knowing your unit will eliminate the guesswork.

As with toilet repair,  AC repair can range in fixes that can be fairly simple as cleaning yet can also indicate that more extensive solutions are needed to be met. When you’re needing an air conditioning service be sure to contact your local HVAC company for assistance so you can find out what solution is right for your system.

How much does it cost to fix air conditioning in a house?

AC repair cost can range anywhere from $193-$311 nationally yet in some cases prices can go higher in which case a replacement would be recommended. Factors that can contribute to the overall price are the extent of damages, the age of the unit, the size of the unit, energy efficiency, or if it’s undergone regular maintenance.

Can you repair AC compressor?

There can be tasks that can assist in AC repair for home units which can get your unit back into action before they impact other parts of your AC system. Some simple fixes that can aid the productivity of your system can be clearing away the debris of your filters to see if they are damaged. If damaged or clogged a simple replacement won’t cost much and can aid in getting your energy efficiency back on track as a clogged filter can cause your AC to use more energy. After this, check your air ducts to see if any spacing is visible and seal it up with synthetic caulk. Other problems could point to unaligned condenser coils, with this, you’ll cover the surrounding parts with a sheet to protect it from water infiltration. You’ll then use a sponge dipped in lukewarm water to scrub the coils and then straighten any bent ones. Finally, using a paintbrush lubricate them with condenser oil so they can be protected.

Can you replace the compressor in an AC unit?

If you’re finding that it’ll be necessary to replace your compressor unit first find out if it’s still under warranty. If it is you’ll be able to replace the unit with only the cost of installation taken into consideration. It’s important to know when to replace the compressor unit versus undergoing AC repair. If no other major components have failed on your AC heat pump or your furnace was recently replaced you should be able to replace the compressor only. As far as troubleshooting issues, if the clutch or bearing are shot than it’ll be best to replace the AC compressor as a whole.

How do I know if my home AC compressor is bad?

A few ways to gauge if there is something wrong with your AC compressor is as follows. First, you can check to see if the air coming out of the compressor fan is cool or lukewarm which indicates wear or a bad compressor. Basically how this works is that gas is compressed to high pressure which creates heat that is then removed by the fan to make sure the overall unit doesn’t overheat. If the air is coming out cool or lukewarm then the compressor is not doing its job. When your compressor is not compressing this gas the overall unit will work in overtime or work longer than it should to try to make up for the loss. This causes heightened use of energy so if you’re seeing abnormally high energy bills this can point to a bad compressor. Another indication of a bad compressor that may call for AC repair or replacement is hearing sounds coming from the AC compressor. A hissing sound usually points to a refrigerant leak while a knocking sound can indicate that the compressor motor isn’t working properly.  Finally, if your air conditioner is taking longer than normal to turn on than this typically indicates an issue somewhere within the AC system.

What are the symptoms of a bad AC compressor?

Symptoms of a Bad AC Compressor

  • Lukewarm Air
  • Higher Electric Bill
  • Hissing or Knocking Sound
  • Coil Buildup
  • Extended Time to Start Up
  • Frequent Breakdowns
  • Overheating

What causes AC unit to stop working?

When AC repair is beyond the power of the unit and it’s shut down there could be many indications that lead up to it. As mentioned before, unclean coils can cause your unit to overwork itself, this with unclean filters will make it overheat until it fails.

AC Repair vs Replace

AC repair can typically be done with units that are still within their expected life span of 10-20 years yet it’s important to point out that once the 10-year mark is hit you may start to see inconsistencies n behavior. It’s therefore important to conduct regular maintenance so you can have an energy efficient system and proper indoor air quality. When problems are localized than AC repairs can be used to fix the issue. If problems amount to a high number, however, you experience frequent break downs or a key component fails it may be cheaper to replace the entire unit. In order to properly gauge the course of action, be sure to rely on a professional HVAC technician in your area for a proper inspection.

HVAC maintenance is critical for the life of your unit as well as the overall air quality in your home.

HVAC Maintenance and Repair

Being a homeowner means being responsible for high-demand appliances like water heaters and HVAC units. For a long lasting air conditioning and heating systems, it’s important to maintain consistent care. This means scheduling regular inspections, making repairs when necessary, and generally maintaining the unit as a whole.

HVAC Maintenance Checklist Form

When it comes to HVAC maintenance it is not recommended to attempt any repairs or replacements on your own. There are many internal and external parts and generally speaking, HVAC maintenance requires a certain level of experience. Whether you have a basic HVAC unit or Tempstar HVAC systems, all HVAC units require regular maintenance and care. For the maintenance there are several things a technician should do, including:

  • Thermostat Check
  • Replace air filters
  • Clean Vents and Ducts
  • Clean Coils
  • Replace belts, pulleys, and batteries
  • Checking and replacing fan motor
  • Inspecting and repairing ignition burner on heater/furnace
  • Checking for gas leaks with a gas furnace

While it is not recommended to perform all of these services on your own, it is recommended to keep a copy of an HVAC maintenance checklist on hand. This can help you keep an eye out for potential problems, but it can also help homeowners identify experienced and inexperienced technicians. Even though repairs are not recommended to attempt on your own, there are a few things homeowners can do without a technician, like the thermostat check.

This check is to determine if you HVAC unit is turning on properly or if there is something wrong. How to check is, change the temperature on the thermostat higher or lower and listen for the unit to turn on. If it it stays on after a few moments, that is a good sign. However, if you hear the unit turn off a few moments after turning on, there could be something wrong with the thermostat settings. That is something that a technician can easily check and update during an inspection.

Why HVAC Maintenance is Important?

It’s important to keep with regular HVAC maintenance in your home or business. Doing so can provide many benefits, including lower energy bills and healthy air. More importantly, regular maintenance means that your HVAC unit is operating properly and is not at risk for potential damage. Ignoring or neglecting an HVAC can lead to serious problems such as needing costly repair, increased risk of safety, and loss of energy efficiency.

HVAC Maintenance Benefits

As mentioned before, there are several benefits to regular HVAC maintenance including:

  • Lower energy bills
  • Healthy air
  • Energy efficiency
  • Longevity
  • Less emergency repairs

Having regular maintenance performed on your HVAC unit has many benefits, but is actually critical to the operation of the unit. When you ignore an HVAC unit, it is not able to perform as it was designed to. This can mean clients will end up paying more, because their unit is working double-time to produce hot or cool air for their home. Energy bills will be higher and there will be more instances when costly repairs are needed. Taking care of your HVAC unit is important, just like having regular maintenance and water heater repair services scheduled. These are high-demand, high-maintenance appliances that require a lot of attention.

Tips for Keeping your Home Warm in Winter

Texas is notorious for its long and hot summers. Many people get tired of the heat, and spend so much time wishing for the weather to cool down that they forget how extremely cold Texas winters can be. The coldest temperature on record for the DFW area is -8 degrees in 1899. While most winter nights don’t get nearly that cold, many people are still looking for the most cost effective way to keep their house warm when the temperatures drop.

What’s the Most Efficient Way to Heat a House?

A room looks warm on a potentially cold day.

If you don’t want to rely on your fireplace, give us a call about home heating installation.

There are many different methods to heating a Texas home. Options range from geothermal heating and natural gas heating, to electric heating and oil heating. Each comes with its own benefits and price tag. However, the primary source of heating efficiency comes from good insulation. Good quality insulation will keep the heat in your home from escaping in the winter, and will keep the heat from getting in during the summer. You may find yourself asking “How can I insulate my house for winter?” Every home is equipped with basic environmental insulation against the elements.

There’s more you can do for keeping a home warm during winter, though.

  • Ensure the weather seal on your doors covers the entire doorway. If there is a gap, or if it is torn or crushed, you can replace it with a new weather seal, or with draft tape. The tape will stick to the inside of the door and block currents of cold air from getting in to your home between the door cracks.
  • If you have a chimney, make sure it is closed, and not blocked or damaged. Only open the flue or damper when actually using the fireplace. If you’re unsure about the status of your fireplace, consider contacting a professional for a chimney inspection or chimney repair.
  • Seal internal and external cracks in your home to keep any air from an escape point. The fewer spaces hot air can move through, the more likely it is to stay in your home.
    Consider covering your air vents when not in use. Cold air can still move through your vents in the winter, and if you’re attempting to keep warm without running the home heater, this will help prevent the room from cooling off too quickly.
  • Weather seal and insulate your windows. Cover them with magnetic seals, and ensure the windows create a seal when closed. If not, replace the weather stripping, or seal the open parts with caulk.
  • Put rugs down on floors to insulate against cold air seeping in at the ground level.

When it gets this cold, call us for a home heating consultation.

After you’ve determined that your home is adequately weather proofed, it’s time to ask yourself “How warm should I keep my house in winter?” An average number of people find 75 degrees Fahrenheit to be their acceptable level of warm. This is less energy efficient than keeping the heating thermostat set lower and offsetting the cold temperatures yourself. If you find yourself wondering “Is it cheaper to keep heating on or turn it on and off?” then you should consider the potential costs associated with both options. If you have your heat on low, then your associated costs will be a smaller, more steady price to keep things heated. However, if you turn your heat off while you’re not home, then the average temperature will drop. Meaning your home heater will have to work extra hard to bring the internal temperature of your home up from lower, resulting in a larger, single cost. It’s up to the individual to determine which is the most cost effective manner of keeping their house warm. Which raises another the question “Does turning the heat down save money?” According to the United States Department of Energy, reducing the temperature of your thermostat by 10 to 15 degrees can save approximately five to 15 percent on your monthly energy bill.

Staying Warm in Winter Tips

Even if you’ve done everything you can think of to technically prepare your home for cold weather, there are always extra steps you can take to keep warm.

We can repair your damaged thermostat, or upgrade your home heating system.

  • Build a Fire If you have a fireplace, using it can help heat your home for the simple cost of a few pieces of firewood. Even if you have the thermostat down low, a fire is a good way to bring up the temperature several degrees.
  • Wear Warm Clothes If the home heater is set to 68 degrees, but this isn’t warm enough for you, consider throwing on thick clothes. A sweater, a thick pair of woolen socks, or even just a thick pair of slippers can help make up the difference and make you much more comfortable.
  • Use the Sun The biggest potential heater you can use is the sun. On days when it’s out, open the curtains for windows that face it. It will help heat up those rooms. Also consider using thermal curtains as additional window insulation.
  • Use other Heat Sources During winter, a popular pastime is cooking or baking meals and snacks for days spent indoors. Once you’re finished baking, and after the oven is turned off, consider leaving the oven open to let the heat move through your house. Only do this if it is safe.
  • Eat Warm Foods Soup and hot beverages are good for warming you up from the inside, out. Go the extra mile and heat up something to eat instead of just making yourself a sandwich.

Heating Maintenance

If your heater breaks or isn’t functioning, don’t panic. There are plenty of heating repair professionals standing by to assess the problem and fix the issue, providing you with the heat you need to live through the bitter Texas winters. If you or someone you know in Fort Worth, TX is looking for home heater repair or replacement, have them contact Metro Air & Heat at (817) 945-3601.

Is a Natural Gas Furnace Right for Your Home?

Book Resting on Chair With Fire in Background

Fires are Nice, But We Generally Rely on the Natural Gas Furnace for Consistent Warmth.

For those of us who don’t have underground propane tanks already installed in the yard, our heating options generally boil down to two options. Gas, or electric. While advocates of both sides can come up with a laundry list of reasons to choose one or the other, many homeowners opt for a natural gas furnace. That’s what we’ll be discussing today.

How do you go about picking a home furnace replacement, and how do you go about caring for it once the unit is installed? After reading through below, you should be able to answer both questions confidently. Here we go!

Important Factors to Consider

When selecting a replacement heater, not every homeowner needs a high-dollar, high efficiency gas furnace. While natural gas furnace BTU rating is important, there are so many other factors to consider, such as size, lifetime expectancy, brand, manufacturer’s warranty, and features. Your family’s future plans (selling the house or staying indefinitely), should also factor into your decision.


How Many Years Does a Furnace Last?

On average, furnaces will function between 15 and 20 years. If you want to keep your furnace at peak efficiency for its full lifespan, that will require some dedication on your part as a homeowner. Once your unit hits the 15 year mark, you should start researching for your next replacement.


How Do I Size a Furnace for My House?

Sizing your new natural gas furnace is actually easier than you may think. Start by taking the square footage of your home and multiplying it times 35 (or 30 if your home has strong insulation). Let’s say your house is 2,000 sq ft in area.

2,000 x 30 = 60,000 Btu needed for your home. Write this number down!


Each furnace product is rated in Btu (British thermal units), which is a way of measuring a unit’s heating power. The furnace also comes with an efficiency rating, which determines how much of that heating power is used effectively. Let’s use a couple examples.

75,000 Btu (input) x 0.8 efficiency rating = 60,000 Btu (output)

60,000 Btu (input) x 0.95 efficiency rating = 57,000 Btu (output)


Both of these theoretical furnaces fall within the acceptable range for the home’s heating needs. That range extends 10 percent below the required Btu and 20 percent above. In other words, for a home that requires 60,000 Btu’s for heating, the acceptable range is 54,000 – 72,000. If you go too low, you won’t be able to heat the house. If you go over, you’ll suffer significant energy losses.


What is the Best Gas Furnace?

According to a Consumer Report conducted from 2011 to 2016, American Standard, Ruud, and Trane are considered most reliable by homeowners. That doesn’t mean you shouldn’t consider other brands, but these three are certainly worth examining. After brand, you should consider efficiency as well. While higher efficiency ratings can save you money on gas expenses, many homeowners have to install special ventilation to accommodate the most efficient models.

Finally, you need to examine the features that are available with each model. Some offer little more than an on/off switch, while others can provide variable speeds and heat production. Talk with your HVAC specialist about which model would work best for your home!

Natural Gas Furnace Issues

Replacing the Cover on a Gas Furnace's Control Box

There are Several Challenges Your Furnace May Face Over the Years, Including Reduced Efficiency.

There are some common malfunctions that your gas furnace may start to exhibit with age, such as:

  • Short cycling (turning off and on frequently)
  • Unstable pilot light
  • Clogged filters
  • Faulty thermostat readings
  • Damaged limit switch
  • Expired ball bearings

While we don’t have time to talk about all these problems today, each one can drastically affect the functionality and efficiency of your furnace. Be sure to talk with an expert if you notice strange noises, hear your system short cycling, or feel the symptoms of carbon monoxide exposure.

The Heat Exchanger

What are the Symptoms of a Bad Heat Exchanger?

The heat exchanger is one of the most active parts in your furnace, absorbing heat from the burning gas and transferring it. It’s made of a durable metal to conduct the heat effectively, but this tough metal starts to crack after years of burning and cooling. A cracked exchanger typically won’t perform as efficiently, so your furnace will have to work harder to raise the temperature.

A damaged exchanger may also allow carbon monoxide to leak into the house, which can cause dizziness, irritate lungs, and even asphyxiate people (with prolonged exposure). You may also notice your exchanger starts to rust when it’s time to replace it. Thankfully, your exchanger will last one or two decades before it requires replacement.

Cleaning Your Furnace

Natural Gas Furnace Cleaning

Cleaning your gas furnace is actually fairly simple.

  1. Start by turning off your furnace and closing the gas flow. Your first step should be to check the filter. If it’s a reusable one, clean it off with a hose and allow it to dry before placing back in the furnace.
  2. Next, open the main compartment of your furnace. Make sure you wear gloves, just in case. Take a shop vacuum with a smaller nozzle attachment. Vacuum up dirt and dust in the main compartment, but be sure to take note if you see any soot. This could be a symptom of a bad exchanger.
  3. If you want to clean out the blower, carefully remove connecting bolts. You may have to get past a control panel to do so. You can clean out the blower fan with a small brush and vacuum.

How Can I Improve the Insulation in My House?

A Picture of a Hand with the Pointer Finger Pushing a Button On a Digital Thermostat

Don’t Touch That Thermostat! Find Out How To Better Insulate Your Home.

We are coming up on colder months, which means we will be using our heating systems more and more. While we need heat in order to be comfortable and safe, it can get expensive running your heating system, especially when your house isn’t well insulated. When a home isn’t well insulated, it is easier for your heat to escape your home, therefore making you use more heat which will then cost more money. Although this can be frustrating to hear, there is no reason to fret! If you are wanting to know how to better insulate your home, we have the tips just for you!

How To Better Insulate Your Home

  • Replace Windows: If your windows are old and you know for a fact that warm air leaks out of them, one of the best things you can do is upgrade to more energy-efficient windows.
  • Use Curtains: Nighttime tends to be the time that is coldest, so using heavy or thick curtains can help keep some of that warm air in.
  • Close Off Bedrooms: Have a room that isn’t being used? Closing doors to rooms that aren’t used as frequently is a great way to keep the heat contained in the areas that you are using.
  • Invest in Rugs: While its hard to believe, wood, tile, or other bare floors that aren’t properly insulated can increase your heat loss. Putting down rugs on bare floors can help curb this issue.
  • A Timer on Thermostat: Leaving your thermostat on heat all day isn’t going to change anything. By setting a timer for when your heat comes on, you can save money on heating bills.

Siding services in Fort Worth, TX are another great way to have better insulation for your home. If you think that you need heating inspection in Fort Worth, TX to determine if insulation is the problem or your heating system, call Metro Air & Heat at (817) 945-3601.

  • Obviously, if your air conditioner is blowing hot air when you have the thermostat set to a cold temperature, something is wrong. Your compressor or refrigerant system may be damaged inside your unit. These are both common air conditioner repair jobs and are easy to fix.
  • Burning or unusual smells should never come from your air conditioner. Burning means that a wire or gears are rubbing against each other and funky odors indicate dead animals in the ducts or mold.
  • If your gears are rubbing together and burning, they are probably also making a grinding noise. If you hear a clunking noise, something has come loose inside the unit.
  • An HVAC unit is supposed to pull moisture from the air, so if you notice high levels of humidity in your home, you need to call for air conditioner repair.

Air Duct Losses – The Hidden Money Sponge

Air Duct Losses

Duct Losses Account for a Large Percentage of Energy Waste Inside Your Home.

Ducts are a crucial part of your home’s air conditioning network. However, they are also an enormous source of home energy waste that many Americans don’t know about. This stems from air duct losses, a hidden money sponge inside your home. Here’s how it happens and what you can do to stop the terrible waste. 

How Air Duct Losses Occur

Air ducts in forced air systems are intentionally manufactured to provide flexibility and resiliency. For a time, they operate smoothly without any issues. Then minuscule cracks, gaps, rips, and tears appear along the vents and in between the various sections. Air inevitably starts to fizzle through the abrasions. In a system that’s constantly cycling air to and fro, these weaknesses are only aggravated over time. The U.S. Department of Energy says that “Duct losses can account for more than 30% of energy consumption for space conditioning, especially if the ducts are in an unconditioned space such as an attic.” So what can the average homeowner do to avert these energy losses?

Solving the Air Loss Problem

There are two clear-cut options to address duct losses: repairs or replacement. With the right insulation, your ducts can be bolstered against the pesky cracks that pop up over time. A professional sealing service will see this done the right way. Otherwise, you could simply say goodbye to your aging duct system and upgrade to a more energy-efficient duct network. High velocity mini ducts offer a great alternative to their rapid distribution capabilities. You can even go ductless with some AC systems, but that might be more expensive in the short term.
