Why Isn’t My Heater Producing Enough Warm Air?

Few things are as inconvenient as a heater that simply won’t keep you warm in the middle of winter. Bundling up with blankets will only do so much. When your heater fails to do the one thing you need it to, you might ask, “Why isn’t my heater producing enough warm air?”

The unfortunate answer is that several things could be preventing your heating system from performing as it should. Our team at Brody Pennell Heating & Air Conditioning is here to explain why you’re experiencing heating system issues and what you can do about it. 

Why Is Your Furnace Not Heating Your Home As It Should?

Whether you have a furnace or another heating system, it should be able to heat your home up to the temperature you have set on your thermostat. When it doesn’t produce enough warm air or even has cold air blowing instead, you could be dealing with a couple of different problems. 

You Have a Malfunctioning Thermostat

Your thermostat sends a message to your furnace telling it how much warm air to produce to warm your home. When it’s broken, you could end up with a cooler or weak airflow. If you think your thermostat is the problem, start the heater troubleshooting process by changing out the batteries. 

You should also make sure you have it in the setting you want. Check if the thermostat is on the “on” or “auto” setting. The “auto” setting turns the fan on only when the furnace produces heat, which is typically what you want. 

The Air Filter Needs Replacing

Over time, this essential component collects quite a lot of dirt, dust, and debris. If you don’t clean or replace it regularly, this debris will build up on the filter and create a clog, which can lead to insufficient warmth for your home and even decreased HVAC efficiency. 

You should change this filter every 90 days or so, doing so more frequently if your home has pets or anyone with respiratory problems. 

Your Ducts Are Leaking Air

The air ducts take the heated air your furnace produces and deliver it to the various rooms around your home. If there’s a leak anywhere in the ductwork, it can create uneven heating and lead to cold air coming out of the vents. 

The best way to fix this problem is by scheduling a professional repair. If your ducts are old or have too many leaks, you may need a replacement.
