How To Fix A Heater Blowing Cold Air

If your heater is blowing cold air, there are a few things you can check to try to fix the problem. Ensure your thermostat is turned up high enough, make sure the heating vents are open and not blocked by furniture or other objects, and investigate whether there is an obstruction in your furnace exhaust pipe. If you have a water heater, check to see if it needs emptying or if something is blocking the vent pipe. You could have problems with your filters, your refrigerant, or other issues that require technicians. Here's what you need to know to learn how to fix a heater.

Check your thermostat.

If your heating system is blowing cold air, you should check to ensure your thermostat is turned up high enough. You should also check to ensure the thermostat is in the "on" position and that the circuit breaker has not been turned off. If the thermostat is in the "on" position and the circuit breaker has not been turned off, you may need to call a professional to fix your heater.

Check your heating vents.

If your heater is blowing cold air, you should check to ensure the heating vents are open and not blocked by furniture or other objects. If the vents are blocked, the air will not circulate properly, and the heater will not be able to heat the room. An expert HVAC contractor can look at your heating and air conditioning system condensers, pumps, and freezers for

If the vents are not blocked, the next thing you should do is check to make sure the furnace is on. If the furnace is not on, the heater will not be able to generate heat.

If the furnace is on, the vents are not blocked, the thermostat is set to the right temperature, the filter is clean, and the air ducts are not blocked, the next thing you should do is make sure the heating elements are not burned out. If the heating elements are burned out, the heater will not be able to generate heat.

Look for obstructions.

If your furnace is blowing cold air, you should investigate whether there is an obstruction in your furnace's exhaust pipe. You can remove the furnace exhaust pipe and check for snags. If you find a block, you can remove it and put the exhaust pipe back in place. If your furnace is still blowing cold air, you may need to have your furnace serviced. Air conditioning and furnace obstructions can cause issues. Outdated filters can create blocks too.

Investigate your water heater.

If the heater blows cold air, the first step is to check if the water heater needs to be emptied. If something is blocking the vent pipe, that will also need to be fixed.

If the water heater doesn't need to be emptied and there's no blockage in the vent pipe, the next step is to check the thermostat. If the thermostat is set too low, that could cause the heater to blow cold air.

If the thermostat is set correctly and there's still no heat, the next step is to check the furnace. If the furnace isn't working, that will cause the heater to blow cold air.

If the furnace is working and there's still no heat, the last step is to call an expert HVAC technician to inspect the heater. A commercial HVAC professional with years of experience in the heating and refrigeration industry can look at your furnaces or cooler and make expert system recommendations.

Work with professionals.

When you need expert refrigeration and heating professionals, you're in luck. A technician can typically diagnose a system's malfunction with ease. For example, if your heater is blowing cold air, there are a few things you can do to try to fix the issue. First, make sure that the heater is set to the correct temperature. If it is set to too high of a temperature, the heater may not be able to keep up and will blow cold air.
