The typical duct system leaks approximately one-third of the air passing through it. This air loss can cost hundreds of dollars a year in energy expenses. This is air you are paying to heat/cool in order to maintain a comfortable home, but instead is leaking into attics, walls, crawl spaces, etc. To compensate, your system has to work overtime to try to keep up resulting in excessive energy expenses, poor comfort and undue stress on your comfort system.

We’ve discussed the Whole House Approach to Comfort in the past and touched on the impact of your duct system. The location of your supply/return registers, the resistance and airflow capacity resulting from the design of your duct system will help or hinder system performance and your comfort. Another major factor is duct leakage. It’s a known fact that all duct systems leak air, the question is to what degree or more importantly, to what result.

If you’ve noticed vents that produce very little airflow in certain rooms, significant temperature differences room to room, the area around your indoor unit is always hot/cold depending on the season, high humidity in the summer, high energy usage or your system seems to run all the time; these are all symptoms of typical duct leakage.

The majority of your duct system is hidden away between floors, walls, attics and crawl spaces. Each and every connection, seam and transition has leakage. The bottom line is conditioned air is leaking into areas outside your living space instead of being delivered to where you need it. In addition, leakage in return duct draws air in from all these unwanted areas. Not only is this affecting your air quality, but air from an attic/crawlspace brings with it extreme temperatures and humidity which creates additional challenges for your system to overcome.

Because most of the duct is inaccessible, it’s been something that we just had to live with. However, we’ve uncovered a technology that allows you to seal the duct system from the inside with virtually no interruption to the living space of the home. Aeroseal is a product that allows you to quantify the actual leakage, seal the holes and measure the improvement in real-time during the process. The end result: improved comfort, reduced energy usage and better air quality.

If your like most of us, we are always looking to save money on energy cost. Below is a quick list of twelve ways to reduce your air conditioning cost this summer.

  1. Stay cool, but not too cool! – The first place to reduce your air conditioning cost is with setting the thermostat to a cool, but not too cool setting. Our customers find they can easily stay pretty cool at 75°F to 78°F. In many cases you can save upwards of 5% in cooling cost for every degree you raise your thermostat.
  2. Don’t trick your thermostat – A thermostats job is to sense heat and adjust to keep you cool. Things like televisions, lamps, PC”s and direct sun light all impact the heat in your home. By turning off these items or pulling down shades will keep your home cooler and reduce your air conditioning cost this summer.
  3. Slow and easy wins the race – When that first hot day comes and you’re ready to turn on your air conditioner, take it easy and set the thermostat to the desired temperature.  Many people will crank the temperature way down to try and boost the cold air. This does not work and will only increase your air conditioning cost. Remember our goal is to reduce your air conditioning cost.
  4. Keep the air flowing – Air flow is very important to keeping a consistent temperature in your home. Make sure that nothing is blocking your vents. When the cool air can circulate with ease, it reduces the need for more cooling, thus reducing your air conditioning cost.
  5. Keep it clean – An easy way to reduce your air conditioning cost is to clean and/or replace your filters monthly. Dirty air filters restrict the air flow and reduce efficiencies.  To make this task even easier we have a Filter Program which delivers filter right to your home! Heck, we will even send you a reminder email monthly so you do not forget.
  6. Get a little help from your friends – Many newer systems do a really good job at removing the hot air from your home, but homes with older systems might struggle to keep up.  In these homes you want to install a whole home ventilating fan in the attic.  Removing extra warm air from your home will create less stress on your system and reduce your air conditioning cost.  A low cost solution would also be to install a window or two.
  7. It’s always cooler in the shade – Just like sitting under a big oak tree on a hot day, it’s always cooler in the shade. Your home is no different, the more you keep the sunlight out the cooler it will be. Make sure to close the blinds that take direct sunlight.  It’s amazing how a little shade can help to reduce your air conditioning cost.
  8. Get sun glasses for your windows – Just like sun glasses protect your eyes from sunlight, window tinting and reflective window film will protect your home from sunlight and unwanted heat. The less heat in your home, the less your air conditioner will run, thus helping to reduce your air conditioning cost. Window film has an added benefit, whereas it also protects your furniture, carpet, and hardwood from fading over time.
  9. Share the cool air – If you have room fans or ceiling fans, turn them on! Moving the cool air around your home will help to even the temperature and reduce the demand, and this will help reduce your air conditioning cost.
  10. Hose it down – Once a year you should spray down (with low pressure water) your outside unit (the condenser). Make sure to turn off the unit at the thermostat before doing this. A clean outside unit will help to make your system more efficient and reduce your air conditioning cost.
  11. Seal it up tight – Often times you will have air leaks in the exposed duct work on or around your main heating and air conditioning unit in your basement. Use metal tape (found at your local big orange box) to seal up those leaks. Sealing these leaks will get more air upstairs to the rest of the house where it belongs. This will reduce demand for cool air and reduce your air conditioning cost.
  12. Going green helps – Like we said it about shade, so why not give back to the planet while reducing your air conditioning cost by planting some trees. This not only helps the environment, but it also will reduce your air conditioning cost by providing shade on those sunny sides of your home.

The answer could be both. Many homes experience excessive dust that can cause pollutants which can increase allergy reactions and decrease air quality. Homeowners try to stay on top of the this by replacing air filters frequently, scheduling regular maintenance, and even purchase expensive air filters just to hold back the dust. But it just keeps coming back.

The logical next step is duct cleaning right? Well maybe. Duct cleaning is a popular way to address dusty homes and in fact I read recently that 13% of Angies List members have regular duct cleaning. The keyword here is “regularly”. That’s right the dust in your duct work comes back after duct cleaning. This routine duct cleaning is not solving your problem.

What if you could not only solve your dust problem without duct cleaning, but you could reduce your annual energy cost by as much as $700.00!

The measured result above are from a typical Aeroseal air duct sealing process:

Have you ever asked yourself where the dust is coming from?

According to the Environmental Protection Agency (EPA) the average home accumulates about 40lbs of dust per year. Where is this coming from, you clean the house weekly, your have good screens on your windows, you have your HVAC serviced and air filters regularly replaced, but you still see the build up on your intake vents, tables, etc.

Let me ask you, have you cleaned behind your walls lately? Of course not, right. But what if I told you that is where the dust could be coming from. Did you know 90% of existing buildings in North America experience small holes on the duct work. These holes continually pump dust and other pollutants into your HVAC system and then out to your home.

The solution is duct sealing.

This process is simple, easy and can reduce your energy cost by as much as $700.00 per year. Duct sealing seals your ducts from the inside and is guaranteed for 10 years , no more annual duct cleaning. GAC is partnered with Aeroseal the nations oldest and best duct sealing manufacturing. One visit from our technicians and we can reduce the duct leakage by 90%.

Stop try to block the dust and stop the dust. Read more about duct sealing now or call one of our comfort consultants.
