Frequently Asked Questions

Most furnaces last 15 to 20 years, depending on how often they’re used and how well they’re cared for. With yearly checkups and regular heater maintenance, they can last even longer. Harker Heating and Cooling recommends checking your furnace filter every 1 to 3 months—especially in winter. Homes with pets, allergies, or lots of dust may need to change filters more often.

Furnace size is based on your home’s unique factors. An expert HVAC technician at Harker Heating and Cooling will evaluate your options to ensure your system heats efficiently.

At Harker Heating and Cooling, we know energy efficiency matters. That’s why our furnace HVAC technicians suggest using a furnace that can adjust its heat output. These models use less natural gas and electricity, helping you stay comfortable while saving money.

The expert HVAC technicians at Harker Heating and Cooling recommend simple steps like changing or cleaning your filter, keeping vents clear, listening for odd noises, and checking your thermostat. For the rest—like checking burners, motors, and electrical parts—leave it to our HVAC experts.

We also recommend annual preventative maintenance to keep your system running safely and efficiently.

You may need to replace your furnace if it’s over 15–20 years old, your energy bills are going up, or it needs frequent repairs. If you’re not sure, the HVAC experts at Harker Heating and Cooling can help you figure out if it’s time for a replacement.

The cost of a new furnace can vary based on the type, size, and efficiency. Schedule a free estimate with Harker Heating and Cooling to find the right furnace for your home and budget.

“I had a Harker Technician do a furnace inspection in our new house. They were very polite and professional, and took the time to educate me on some things concerning the system, as this is my first house. I am very satisfied with their service!”
