How To Detect Air Duct Leaks

HVAC systems can frequently have air ducts leaks. There’s nothing worrisome about it. You need to detect the location of these leaks first.

What Symptoms Indicate An Air Duct Leak?

1.    Expensive Utility Bills:

High electricity bills are one of the most prominent symptoms of an air duct leak. Because your air ducts transmit conditioner air when there is a leak, part of the conditioned air escapes before reaching the regions that need it the most. As a consequence, your air conditioner needs to work more to keep your home cool. This additional labor stresses the unit, requiring more energy to maintain running and higher energy costs.

2.    You’re Doing A Better Job Of Dusting:

If you run your finger across a surface and see a lot of dust, your air ducts might be to blame. Leaking ductwork may draw dust from your attic and basement and disseminate it throughout your house. While dust isn’t strictly dangerous in and of itself, it may have a detrimental impact on air quality and damage individuals with allergies or respiratory disorders over time.

3.    You Have Uneven Temperature Throughout Your House:

Hot and cold patches in your home are another indicator of an air duct leak. Uneven cooling occurs due to leaked air gathering in one place and other regions not receiving conditioned air as a result.

It may make your house quite unpleasant and put a burden on your HVAC system. If left unattended, this might shorten the life of your device.
