Your Palos Heights, IL, area and the surrounding suburbs, home’s heating, ventilation, and air conditioning (HVAC) system’s energy efficiency is vital to both your home’s comfort level and energy-cost savings. There are many components to your energy efficiency that work in tandem to provide you with the results you want and expect.

Our home solutions advisors are highly educated and trained, not to mention work very hard, to balance and fine-tune all your HVAC elements to perfectly suit your needs. One of these critical components is your home’s ductwork, also called air ducts or ducts.

If your ducts are leaking, it is impossible to reach the level of comfort you want in your home. Additionally, when your ductwork has issues with its seals, you are leaking energy, which costs you money, as well as inviting health issues into your home. At Doornbos Heating and Air Conditioning, we take your ductwork and sealing very seriously.

Why You Need Duct Sealing Services

Air ducts are constructed from different materials. Chances are your home’s ductwork is fabricated from either galvanized steel, aluminum, polyurethane and phenolic panels, fiberglass duct board, or flexible ducting—or a combination of these materials.

When your ducts were new, they may or may not have been properly installed. If they were not, you could have been experiencing leaks and issues all along.

When air ducts are initially installed, the installers seal the seams between duct pieces and at connections. If the installers are not appropriately trained, they may use incorrect materials to seal the seams or may simply execute the job in an inferior manner. Either way, you suffer the negative effects.

Even if your ductwork was installed well, over time seam seals break down, allowing leakage. Materials can shift and rust as well, also causing leaks.

Duct leakage does more than reduce your ability to achieve precise comfort levels in your Chicago area home. It also decreases your home’s indoor air quality (IAQ), as matter like dust, dander, and mold are pulled in through the leaky ducts and then circulate throughout your home.

Having poor indoor air quality can be dangerous, leading to chronic health issues. If someone in your home already suffers from illnesses, allergies, or asthma, poor indoor air certainly exacerbates these conditions.

At Doornbos, we rely on the excellence and innovative process of award-winning Aeroseal for sealing ductwork. Aeroseal is a safe and durable service for automatically finding and sealing any and all leaks in your duct system. In addition to noticing the difference in your home immediately, you will see the verified before-and-after results in a printed certificate.

Duct Sealing Benefits

The benefits from duct sealing are widespread.

First, your heating and cooling system can reach its optimum performance, affording you the level of comfort you want in your home.

Second, with no wasted or leaking energy from your ducts, your HVAC system can operate at its proper level without stressing it to work harder, trying to keep up with the heated or cooled air you are continuously losing. This helps prevent unexpected repairs or breakdowns and extends the life of your system.

Third, without leaking air, all your heating and cooling energy is being used as intended. This saves you money since your energy costs are on par with your system’s energy efficiency. In fact, studies have shown you can save between 20 to 40 percent on your energy costs after sealing your ducts.

Fourth, your indoor air quality will improve. With this comes better health for all those in your home.
