Why Is My House Drafty?

With Cincinnati’s sweltering summers and frigid winters, drafts don’t only make you uncomfortable inside your home. Drafts suck your energy dollars right through the cracks and crevices you didn’t even know you had. You might think old doors and windows are the culprit, but hidden problems with your insulation and ductwork are probably to blame for costly air leakage. At National Heating and Air Conditioning, we’ll identify air leaks and offer affordable solutions to keep your conditioned air where it should be—inside your home.

What Is an Energy Audit?

Don’t worry about the negative reaction you get when you hear the word “audit.” An energy audit is actually an effective tool in identifying where the drafts in your home are coming from. A technician from National will thoroughly inspect every part of your home using infrared thermography to find air leaks. Infrared thermography utilizes cool infrared cameras to detect air leaks in walls, crawlspaces and in the attic. Additionally, we’ll use a blower to measure exactly how much air is leaking through these cracks. After finding the weak spots and identifying areas where insulation is degrading or missing, we’ll offer up a plan to seal the leaks and make your home as energy-efficient as possible.

What Are the Best Options for Eliminating Drafts?

New Insulation

Over time, the insulation in your home’s walls and attic will degrade and settle, leading to drafts, higher energy bills, uneven temperatures and indoor air quality problems. In some cases, the insulation was incorrectly installed. The trained technicians at National will evaluate the condition of your insulation and recommend an upgrade if necessary.

Air Sealing

Air leakage is the biggest cause of energy waste in American homes and commercial buildings. Unseen gaps and crevices leak about the same amount of air as leaving a window open year round while operating your HVAC unit. These gaps and cracks are often overlooked as a reason for drafts, but eliminating air leakage will make your home more comfortable and energy efficient.

When you choose air sealing services from National, our team will inspect your home, especially in the attic and crawlspaces, for air leaks and apply caulking, foam or a combination of these and other materials to seal the leaks. Air sealing in conjunction with new insulation is the most efficient way to reduce air leakage in your home.

Duct Sealing

Air leaks from ductwork occur in more than 90 percent of America’s homes and businesses. At National, we use a state-of-the-art product called Aeroseal to plug the leaks in your ductwork. This patented technology seals ductwork from the inside out using liquid polymers that bind together and fill the gaps where air is seeping out. Aeroseal is non-toxic and safe for use in your home.

Do I Need my Ducts Cleaned?

Experts do not recommend duct cleaning as an effective way to improve indoor air quality. This is because the bulk of dust and other indoor air contaminants that enter your home through your duct system actually come from the crawlspace, attic and walls. Leaky ducts allow this dust to enter…
