A furnace that’s blowing cold air during the winter months can be a huge headache. Luckily, this is a common issue that can often be fixed. Let’s take a look at a few things that might be wrong with your equipment and how you can rectify them.

Incorrect Thermostat Settings

Sometimes, the easiest solution is the correct one. If the season has just started and your furnace is blowing cold air, someone might have changed the thermostat setting. Or, it could be that your thermostat is malfunctioning. This is why getting your equipment checked by a professional at least once a year is always a good idea. And if you’re still using a manual thermostat, it’s time for an upgrade.

The Furnace’s Pilot Light Is Out

When a pilot light is lit on a new furnace, it will often stay that way until you extinguish it yourself. But as your equipment gets older, it’s common for the pilot light to go out between heating seasons. There’s a good chance that the system is either not blowing warm air or not turning on at all because the pilot light needs to be reignited.

Extremely Dirty Air Filter

The air filter is such a small part of an HVAC system that homeowners often forget to check it. In reality, it’s an extremely important part of cleaning your air and maintaining the system. In addition to causing contaminants to re-enter the air, an extremely dirty air filter can impede the full heating of the air. You can fix this by either replacing or cleaning the filter, depending on what type of filter your system uses.

Air Ducts Leaking Warm Air Instead of Cold Air

Your ductwork operates behind the scenes, meaning that you rarely access its inner workings. If your air ducts have become damaged with multiple tears and holes, this will cause warm air to leak before it reaches the registers. You should have your ducts checked at least every couple of years to prevent any problems.
