Is Air Escaping Your Home?

Have you noticed a spike in your electric bill this winter? When’s the last time you checked your windows and doors for leaks? The air escaping could cost you a fortune. According to the Department of Energy, heating and cooling account for about 48 percent of the energy use in a typical U.S. home, making it the largest energy expense for most homes. At J&W Heating and Air, we don’t want you to lose money just because you want to keep your home at a comfortable temperature. If you think air is leaving your home when it shouldn’t, we have some ways you can avoid it.

Where is the Air Escaping?


Insulation, doors and windows are not the only places your air leaks out from! According to, the majority of your air is escaping through the walls, floor and ceiling, which accounts for 31 percent of leaked air. Your home’s ducts and fireplace are the second biggest source at about 15 percent each, flaws in your plumbing allow about 13 percent, doors and windows are 10 percent each and fans and vents come in at 4 percent. That’s a lot of leaking air and a lot of money out of your pocket. Leaks are very easy to fix and prevent.


If you think there’s something wrong, don’t wait to have one of our HVAC professionals take a look! Our professionals can perform maintenance to determine if your home is leaking air. If your home is lacking proper sealing and insulation, the escaping air could be increasing your energy bill. It’s important to find a solution before the summer heat arrives and now is a perfect time. Let us check your air ducts and attic insulation for leaks to ensure your home is properly sealed. We also offer regular preventative maintenance to ensure your system is functioning at peak efficiency at all times.

Is Your Insulation Sufficient?

Old or lack of attic insulation might be what’s causing your air conditioner to run more than necessary. The air in an attic can become very hot and if it’s not insulated well, the hot air can enter your home. This makes your air conditioning unit run more often, work harder and cost you more each month. Proper insulation in your walls, attic and around your windows and doors will keep your system running efficiently. According to the U.S. Energy Information Administration, more than 90% of the 116 million homes in the United States are expected to have higher heating costs this winter compared with last winter. Did you know says improper insulation can decrease your system’s efficiency by 90 percent? You don’t want to be apart of those numbers! Have no fear, our HVAC experts at J&W Heating and Air offer quality repair, installation and maintenance services throughout the Jacksonville area.


Here’s a fact for ‘ya: proper ventilation goes hand in hand with proper insulation. Most people don’t think ventilation is vital to heating your home, but news flash, it’s super important. Good ventilation protects you and your family from inhaling unpleasant odors and harmful gases. It rids your home of pollutants that are potentially hazardous to your health. Ventilation keeps your home free from mold and mildew, which can ruin your walls and give off bad smells. Clean, filtered air prevents damage caused to your house and respiratory system.

Have You Checked Your Air Ducts?

If your air ducts are older than 8 years old, they may have leaks that are costing you money. Without being properly sealed, your ducts could have holes that are letting air escape into the walls. You’ll know it’s time for an aeroseal duct sealing if your energy bills seem really high and if some vents have less airflow than others. Did you know poor air duct cleanings can actually decrease your indoor air quality? At J&W Heating and Air, our experienced technicians will work with your current ducts to make them airtight and save you money.

Aeroseal will cause escaping air to pressurize and attach polymer particles to the edges of every leak until the leak is sealed up entirely. According to, 30 cents of every one dollar spent on heating and cooling a home disappears through leaky ducts. Don’t let your ducts drive up your energy bills. Let our team help improve your AC unit’s efficiency and get your home back to peak comfort!


Don’t let escaping air drive your electric bill. You deserve to know that your comfort is in good hands, which is why it’s so important to schedule your HVAC and indoor air quality services with J&W Heating and Air. Only with a qualified, experienced professional can you rest assured that your service is completed properly and efficiently. Call today and let us put an end to that escaping air!

Just had an entirely new, full HVAC install done at our old house in Riverside, which was a fairly big job. Brian and... Will did the installation, and were awesome. There was going to be issues leveling the air handler in the attic, so they moved it to a new spot and hung it instead, getting new parts/changing the plan on the fly. We're much happier with this new setup and location of the air handler. I really appreciated this, their professionalism/thoroughness, and flexibility. Brian and Will worked super-hard, and double-checked everything once the job was done. Would use this company more

Two installers here early this morning. Worked all day. Very professional, extremely well mannered and quick to answer... all my questions. They are Dustin and Robert. Both men went above just installing my new unit, they were personable and knowledgeable in what they were doing. I was surprised when I found out these two hadn't been working that long together. They worked extremely well together. I highly recommend this two more

A snake crawled into my outdoor condenser and stopped my 16 year old Trane last week on Thursday. The power surge took... out my blower unit circuit board and the motor. I called J&W and Rob was over within two hours of my call. I was spec'd a new York 17 seer system and it was up and running on Monday. Technicians Jason and Brian arrived promptly and every facet of the installation was thorough. When completed, I would not of even known they were there except they left my garage cleaner! Thanks J&W!read more
