Do You Need a New Furnace or is it Just Time to Repair?

  • February 27, 2014

Repair vs. Replace Decision Tree

  • Age: If your heat pump or air conditioner is more than a decade old, and your furnace is more than 15 years old, you are losing money from low energy efficiency. The federal Energy Star program can point you to new furnaces achieving 98.5 percent Annual Fuel Utilization Efficiency (AFUE).
  • Pollutants: Indoor noise pollution from an old furnace means ductwork is mismatched with the furnace size, or your cooling equipment’s indoor coil is faulty. Old, leaky ducts can suck dust from unoccupied parts of the house (crawl spaces, attic) and spread it throughout your home.
  • Too hot or too cold: If room temperatures are out of whack, your furnace may be struggling to overcome its own inefficiency, ductwork design problems, or poor insulation.
  • Humidity havoc: Wild fluctuations in humidity can mean inadequate HVAC equipment, leaky ductwork, or deteriorating efficiency in both your furnace and air conditioner. You probably need a new furnace.
  • Get with the program: If you leave your Moore County home for extended periods and do not have a programmable thermostat, you are wasting your energy dollars.
  • Furnace buddies: If your HVAC technician is a frequent visitor to your home for constant repairs, your furnace may be past the point where patching is economical. Look at a few seasons’ worth of energy bills to chart the trend. Escalating expenses mean you need a new furnace.


A whole-system replacement is actually your best strategy when debating if you need a new furnace. Get your high efficiency, Energy Star-certified furnace and air conditioner installed at the same time, so ductwork can be modified for maximum savings. Purchasing heating and cooling systems designed to work together and having properly designed ductwork is your least expensive option in the long run. The energy savings pile up year after year.
