We are taking the following precautions due to the COVID-19 virus. All of our technicians have masks, glasses, latex gloves and shoe booties if they have to enter your home. Our technicians also have hand sanitizer and disinfectants that they use after every call.
If we are there to do maintenance and we don’t have to come inside your home to get to the equipment, we are asking homeowners to adjust the thermostat for us so we can do the system maintenance without entering the home. We will not be shaking hands and will keep our distance from customers.
How to Detect and Seal Leaking Air Ducts in Your Attic
Leaky air ducts in your home HVAC system can account for a significant loss of conditioned air. Air loss can waste energy, reduce the efficiency and effectiveness of your HVAC equipment and drive up your heating and cooling bills. The following guide will help you find and seal leaking air ducts in your attic.
Take safety precautions and enter the attic: Wear appropriate safety gear when you go into your attic. This might include goggles, gloves, a filtering face mask, overalls to protect skin and clothing and heavy work shoes. Be cautious when moving across joists or floor beams.
Find the ductwork: Ductwork will most likely be hidden underneath insulation, so remove or pull back attic insulation to expose the duct pipes. Then, find the connective points in your ductwork, as these are the most likely spots for leaks. Look for broken seals, loose or detached duct sections, or damage to the ductwork.
Feel for leaks: Make sure your HVAC system is moving air through your ducts. Then, take off your gloves, and put your hand near connections and other areas of suspected leaks. If you can feel air coming out of your ducts, you have a leak.
Listen for leaks: Sometimes leaky ducts make whistling noises or other sounds when air is escaping. Listen closely for these sounds.
Look for leaks: Use a smoke pencil to physically check for duct leaks. These devices emit a thin stream of smoke that will move if air is escaping. An incense stick is a great alternative if you don’t have a smoke pencil.
Seal leaks: Make sure all sections of your ductwork fit tightly together. Then, apply mastic tape — a specialized sealant used on ducts — to all connections. If necessary, call your HVAC professional for duct inspection and repair.
