If your furnace isn’t delivering enough heat to keep your Hillsborough home warm and toasty, it doesn’t necessarily mean that you need a furnace replacement. Here are three common reasons for insufficient heat, even when you’ve set the thermostat high enough to get the job done:

You May Need a Furnace Repair

A simple thermostat calibration may be all that’s needed to correct the problem. Insufficient heat could also be due to a condensate drain line that’s obstructed by sediment or growth and causing the heating system to shut down. Airflow obstructions in other parts of the system can reduce heating output by causing the furnace heat exchanger to constantly overheat, shut off prematurely and then start up again.

You May Need Ductwork Cleaning or Sealing

North Carolina homes can lose 20 to 30 percent of heated air through damaged ductwork. Over time, ducts crack or develop holes through which heated air escapes. Dirty ducts can not only pollute your home, but they can also cause a chilly home if obstructions in ductwork are blocking air flow. Heated air will not be as warm when it reaches its destination rooms as it was when it left the heating unit.

You May Need Heating Maintenance

Annual heating maintenance includes a thorough equipment cleaning. Dirty equipment doesn’t heat as effectively as clean equipment. All that dirt makes your furnace overwork, especially if your air filter is clogged as well. If you haven’t had a tune-up lately, schedule preventive maintenance. If dirty buildup is not causing the problem, your service technician can tell you what is.

A lack of heating maintenance is responsible for up to 95 percent of furnace breakdowns, repairs and higher-than-necessary energy bills.
