Top 100 HVAC Blog Post

Don’t be alarmed if your furnace is pumping chilly air instead of warm air. It’s possible that the solution is straightforward. Find out why your furnace is spewing chilly air and what you can do about it.

Reasons Your Furnace is Blowing Cold Air

Remember that a cold furnace normally indicates a problem, but it isn’t always a “major” issue. Before hiring an HVAC specialist, you can run your own assessment to see whether it’s something you can handle yourself. Look for the source of the problem in the locations listed below.

 

1.Ductwork Leaking

Not only does leaking ductwork allow warm air from your furnace to escape, but it also allows cold air from the outside to enter. Even little leaks can have an impact on your home’s temperature and lower your furnace’s overall performance. Locating leaks or holes in your ducts may require the assistance of a specialist.

2.Air Filter

Filters that are dirty or blocked hinder warm air from moving in your furnace. Replace your air filter every month or two to ensure maximum performance. Additionally, high-quality filters should be purchased to ensure appropriate indoor air quality.

Sometimes the issue is as simple as a malfunctioning thermostat. Check that the thermostat is set to “on” and that the batteries are charged. It’s possible that the thermostat, if it’s electric, has lost power.
