Why Is My Heater Blowing Cold Air?
February 01, 2022
During a New Jersey winter, nobody wants to come home to find chilly air coming out of their vents. If your heater is making the air in your home just as cold as the air outside, there could be a few causes. Read below for ways to diagnose the problem and steps you can take to keep your home warm.
Clogged Air Filter
If your heating system is blowing cold air when the heat is turned on, the first place you should look is your filter. Clogged air filters are the leading cause of heaters blowing cold air. If your filter is clogged with dirt and debris, warm air won't be able to get through and to your home. If you change the filter and still run into problems, dirt and debris could have made their way into your system. If you think this is the case, call a professional HVAC tech at A.J. Perri to help you diagnose and solve the problem.
Even if your thermostat is set to the correct temperature to warm your home, there could still be problems with the system that causes cold air to blow. The most common problem with thermostats is a wiring issue, especially if you installed your thermostat yourself. You could also have a specific thermostat that isn't compatible with your home's current heating system. Let a professional look at your thermostat to see if that is the root cause of your heating problems.
If you have an older heating system in your home, mechanical issues can be why your heat isn't working as it should. Furnaces are made up of several moving parts and processes, all it takes is one small thing to go wrong, and the entire system can malfunction. Also, as your furnace gets older, its performance starts to decline, and the system is more likely to overheat. This is especially true if your furnace is over fifteen years old or if you haven't been keeping up with the maintenance. It's always a good idea to get an expert to take a look at your heater to see if it needs to be repaired or replaced.
Leaky Air Ducts
Leaky air ducts could cause another reason your heater is blowing cold air. There are air ducts that run throughout your home. If one of these ducts has a small hole in it, the warm air can leak out of it and not make it to your vents and into your home. If this is the case, finding the leak and repairing it are best left to a professional. Call an HVAC tech to repair your leaky air ducts as quickly as possible.
