Reasons Your Heating System Isn’t Producing Warm Air

When your furnace isn’t fulfilling its purpose, it can feel like the end of the world. Luckily, a heatless heater is a standard issue that can be corrected with repairs. There are a few common causes for this problem, many of which a technician can solve.

Your HVAC Filter Needs To Be Replaced

Your air filter is the key to a fully functioning heating and cooling system. The device is responsible for catching airborne contaminants within your home. Not only does it keep your indoor air healthy, but it also keeps your heater working properly.

When your filter accumulates lots of debris, it can create a clog. A blockage can reduce airflow within your heater, causing the unit to not produce warm air. Professionals recommend changing your filter every three months. Doing so will prevent wear and tear to your heating unit.

The Ductwork Is Damaged

Most HVAC components begin to falter with age. Your ductwork is no exception, for it can form leaks and other damages over time. Cracks in your ducts can cause warm air to escape, making your home feel colder than it should. A technician can inspect your ductwork and perform maintenance to correct the issue.

Your Condensate Line Is Clogged

When your condensate line is backed up, it can restrict the airflow to your furnace. Your unit may not start, or it may not operate as it should! A clogged condensate line can occur due to debris or algae growth within the drain line. You should check your line occasionally to ensure no obstructions are preventing your furnace from producing warm air!

The Thermostat Is On The Wrong Setting

While it may seem obvious, your unit may be blowing cool air due to your thermostat settings! As the seasons change, many homeowners forget to alter the system for winter. You can prepare the device by changing the setting to “heat.”

When Is It Time For A Heater Replacement?

No heating system lasts forever! That’s why you must monitor your unit to pinpoint when a replacement is officially needed. A few factors can signal that it’s time for a new installation, some of which are:

  • Your system is more than 15 years old
  • There’s a frequent need for repairs
  • Utility bills are higher than usual
  • Unit produces little to no heat
  • Your system doesn’t start

If you suspect you’re in need of a replacement, our team of professionals can help you make the final decision! We’ll provide you with a recommendation that will suit your personal needs.
