Are there questions bothering you about air duct maintenance and repair?
Why fiberglass ducts are considered good?
Fiberglass is one of the materials used for air ducts according to our specialists in Pacoima. This is a high quality material and if it's coated with acrylic materials, the ducts will be better protected and less noisy. They are a bit more expensive but they are worth it since air duct replacement doesn't take place often.
Why sheet metal ducts should not be my first choice?
Air duct replacement is usually needed once in a lifetime. Since their condition will determine your good quality indoor air, temperatures and health, invest in them. Sheet metal is usually uninsulated and prone to crack easier. So, if you choose them due to their cheap price, make sure to insulate them externally.
Why does the HVAC thermostat never stop?
The thermostat is programmed to stop the operation of the unit when it has reached the desired temperatures. When the air ducts are damaged and there's air leakage, there will be no sufficient air and the HVAC unit won't work properly. You will need air duct repair and make sure to seal all cracks.
