Why Is My Furnace Inadequate at Warming the House?

cold-man-with-thermostatThis is not the way you want to start the winter—with a furnace that turns on but falls short of providing the comfort you expect.

We have good news and bad news about your underperforming furnace. The good news is that the problem may turn out to be a simple one that you can correct yourself. The bad news is that it may … well, not be simple. However, if you find yourself with a furnace in the second category, you don’t have to worry about trying to fix it. In fact, you should never attempt to fix it. For furnace repair in Howell, MI, call on the top professionals in the area—the First Choice Heating & Cooling HVAC technicians.

Here are simple reasons your furnace may not be cooling the house

Let’s start with some basic trouble-shooting. If your furnace isn’t providing enough warmth, or the warmth is uneven around the rooms or floors, these are simple possibilities:

  • The furnace filter is fully clogged and needs to be changed for a new one. The filter is one of the first parts of an HVAC system to check when something isn’t working right, because a clogged filter causes everything to work poorer. Choked off airflow means less warm air sent around your house. We strongly recommend you check the filter monthly to see if it needs to be changed. Most filters need to be replaced every 1 to 3 months.
  • The thermostat is set incorrectly. Does this seem too simple? It happens all the time and people overlook it. If it’s the start of the cold weather, you may have the wrong settings still programmed into the thermostat.
  • Poor insulation around the house. The furnace may not have a problem—you’ve got windows that need caulking and weather-stripping to put around the doors. Maybe the attic needs better insulation.

The more serious furnace issues

Now we get into the furnace malfunctions that need to have a professional to fix. Don’t worry about the diagnosis; that’s what our technicians are for!

  • The blower fan in the air handler is broken. If the fan starts to lose power, it can’t send enough heated air around the house.
  • The burners aren’t all igniting in the burner assembly. This can happen because of grime and rust, artifacts of poor furnace maintenance. Technicians must remove the burner assembly and clean it.
  • One or more heating elements has failed. This is a problem in electric furnaces only, but it’s the most common reason for one to start losing heating power.
  • The furnace is going through short-cycling, which means for one of a number of reasons it’s shutting off early and not completing a full heating cycle. Technicians can deduce what is causing this.
  • The furnace is coming to the end of its service life and it needs to be replaced. If your furnace is more than 15 years old, this is the likeliest problem.

You can trust our team to find out exactly what’s wrong with your heating system and have it repaired.
