Should You Repair or Replace Your Furnace?
If your furnace is under twelve years old and facing an isolated issue like a failed igniter, dirty flame sensor, or worn blower capacitor, targeted repair is generally the most economical choice. However, if your furnace has a cracked heat exchanger, requires costly major component replacements, or is over fifteen years old, replacing it with a modern high-AFUE furnace or dual-fuel heat pump will lower heating costs and ensure household safety.
Frequently Asked Questions
Why is my furnace blowing air but no heat?
A furnace blowing room-temperature air is often caused by a dirty air filter restricting airflow and triggering an overheating limit switch, an extinguished pilot flame, or an oxidized flame sensor that fails to verify the burner flame.
How often should my furnace receive professional service?
We recommend an annual furnace inspection and safety tune-up in early fall before chilly winter weather arrives. Routine maintenance ensures burner tubes are clean, flues vent exhaust safely, and heat exchangers are intact.
What should I do if my carbon monoxide alarm sounds?
If your carbon monoxide alarm sounds, evacuate all occupants and pets immediately, open windows if safely possible, and call your local gas utility or emergency services from outside. Do not run the furnace until it has been inspected by a certified technician.
What does the AFUE rating on a furnace mean?
AFUE stands for Annual Fuel Utilization Efficiency. A furnace rated at 80% AFUE converts 80% of fuel into usable heat while 20% escapes through the exhaust, whereas modern 96% high-efficiency condensing furnaces waste only 4% of fuel.
Can I finance a replacement furnace system?
Yes, we provide flexible financing options through Wisetack with transparent terms, manageable monthly installments, and no prepayment penalties.
