Here is a Comfort Tip: How to get the most out of your furnace

Yearly professional cleaning and maintenance as well as frequent filter changes is critical. A well-maintained furnace can last at least 15 to 20 years according to furnace manufacture Carrier, but completing annual maintenance and being diligent with repairs can extend its life even longer.

WHAT AFFECTS HOW LONG MY FURNACE LASTS?

Size – It’s important to have an appropriately sized system for your home. Make sure your contractor performs a proper load calculation on your home. Btu input and blower size is critical.

     • Shorter cycles create more wear and tear on the parts of a furnace, so if the system is larger than necessary, it will turn on and off too quickly.

     • Furnaces that are too small for the space may stay on too long and     struggle to heat your home, which can also add wear and tear on parts.

Installation – It’s important to have a professional correctly install your system

     • Incorrectly designed, sized, and sealed ductwork impacts airflow and comfort

     • Poor drainage can cause damage to the AC and furnace

     • Incorrectly installed electrical, refrigerant and gas lines can cause damage to the system and pose a safety issue for you and your family.

Lack of routine maintenance – it’s important that you are regularly maintaining your system.

     • Dirty filters can cause wear on your blower

     • Minor repairs can turn into costly problems

     • Equipment life span can be reduced

Thermostat set too high or too low—the optimal range is between 60 °F and 80 °F
