Why Is My Furnace Blowing Cold Air?

Learn Why The Heat Is On But Not Blowing Hot Air

No matter the time of year, furnace maintenance is one of the best things a homeowner can do to maintain comfort in their home. If you have the heat on, but it’s not blowing hot air, then your system is in need of a check-up.

There are many possible reasons why your unit might be failing to produce heat. The good news is that by knowing the signs of an issue — finding the problem can be easy. King Of Comfort is your HVAC ally in Indianapolis when furnace repair is needed.

Checking Your Thermostat

Before checking in with your furnace, inspecting your thermostat is a good place to start. The problem could be simpler than you might think.

Your Thermostat Settings Are Being Changed

There’s a reason family members are often protective of the home thermostat. Depending on the number of people living in your home, it’s possible someone may be altering the settings without your knowledge. Pay attention to the status of the thermostat, and if there are children in your home, consider having the device professionally moved somewhere out of their reach.

Your Thermostat Needs Batteries

If your thermostat’s batteries are dying, then the lack of heat might be remedied by a simple battery change. It’s a good idea to replace your thermostat’s batteries at least once a year. If it’s been a while since you last did so, this might help with the problem.

Your Fan Is On The Wrong Setting

Your thermostat should have an “auto” mode, which will stop the fan from blowing cold air after you’ve reached the temperature you want. If the fan is on a different setting, it may operate more than necessary. By switching to “auto” mode, you can make your home more comfortable while also saving on electric bills.

Checking Your Furnace

If the thermostat is fully functioning, yet there’s cold air coming out of your vents when the heat is on, it’s time to take a look at your unit. Your system is the heart of your home’s heating system, so proper maintenance is crucial for the livability of your household. For every heater problem you might encounter, King Of Comfort offers you our dependable services!

A Dirty Air Filter

Having an air filter that’s dirty and clogged with debris will negatively impact your home’s heating. If your filter is reusable, removing and cleaning it with soapy water or compressed air should alleviate this issue. Otherwise, you should simply replace it with a new one.

Regularly cleaning your air filter is the key to maintaining your home systems. It should ideally be done every three months. Remember that seasons of more active use will make your air filter dirtier faster, so earlier replacement may be necessary!

Low Fuel Amount

You might find that your furnace has run out of fuel. You’ll want to call in a professional to correct this problem, but it’s still beneficial to check for other problems in case it is not an isolated issue.

Limit Switch Problems

High-limit switches keep your furnace from overheating, which can often be caused by line blockages. A malfunctioning limit switch might be the culprit for your problem. Contact one of our professionals as soon as possible to correct this problem, because letting this particular issue last can damage your heating system.

Other Problems

When it comes to your home’s heating, the range of possible problems is plentiful. The best choice, especially when you cannot determine the fault in your heater, is always to turn to HVAC professionals like King Of Comfort. Here are some example issues at your home that might be related:

  • If you’re wondering, “Does antifreeze affect heat?” The answer is yes! Antifreeze leaks can prevent adequate heating.
  • Your burners could be clogged with debris.
  • The flame sensor is potentially failing to detect flames, thus disabling your unit.
  • If your unit has a pilot light, it might not be turned on.

As always, dealing with a heater can be complicated and dangerous, so it is best left to the professionals. Before thinking about delving into your home heater, seek out our team of HVAC experts.
