Subtle Signs That Your Furnace Isn't Working Effectively

Sometimes it's easy to take for granted turning up the thermostat on a cold, blustery day. The sudden rush of heat provides warmth and comfort at the touch of a button. When the heat doesn't turn on or you notice it is taking way too long to heat your space, your furnace is definitely in need of some TLC. Contacting a heating contractor at the first sign of a problem can help save you time and money. Other than your unit not working at all, here are some subtle signs you should have your furnace checked.

Fluctuating Energy Bills

One way to really take a closer look at the efficiency of your HVAC unit is to examine your energy bill. Both your natural gas bill in addition to your electric bill can tell you a lot of things about the energy output of your furnace. Look more at your bill history for the past 12 to 24 months as opposed to the previous month. This will tell you how much energy usage you typically use at that time of the year. If you see a drastic difference of more than 25 percent, there is a good possibility that your furnace needs to be serviced.

Condensation Buildup

Any type of buildup of moisture on your walls or windows is a good indication that your furnace may not be working to industry standards. Your furnace should be generating modulating heat and adjusting itself properly to the air temperature readings on your thermostat. A qualified HVAC repair specialist will be able to determine if your furnace is generating and distributing heat properly. He will also look at the insulating factors in your home. Drafty windows and other areas where cold air seep through can make your furnace less effective and work harder than it should.  

Furnace Turns On And Off

It can be frustrating when your furnace blows out hot air for a few minutes but doesn't finish its entire cycle. It may turn on and off intermittently. This doesn't allow the room to come to the full desired temperature. In many cases, the problem can be something as simple as a dirty or clogged furnace filter. Having your ductwork cleaned out and sealed for air leaks can also help improve air flow into each room.  

Furnace Blows Out Cool Air

If you turn on your furnace and notice the air coming out is not as warm as you think it should be, it's time to get it checked out. Often it could have a faulty thermostat or flame sensor. Repairing the unit will help restore both heat and proper airflow through the ductwork.

Some signs are easy to recognize with furnace troubleshooting while others are more complex. Take the guesswork out of what is wrong by having a heating and cooling pro like Clay's Climate Control LLC service your furnace.
