How can I get the most out of a new furnace?

Our number one recommendation is changing your air filters every 90 days. Purchase several air filters online or at your local hardware store. Then set reminders to swap them out every 90 days. If you have pets, we recommend replacing your air filters every 30 days. Pet hair will get sucked through your return ducts and clog the filter pretty quickly. Clogged and dirty air filters can cause your heat exchanger to overheat and crack. Cracked heat exchangers are costly to replace. In fact, most folks with a cracked heat exchanger end up replacing the entire furnace.

How do I know if my furnace is inefficient?

If your furnace is more than 15 years old, it is considered inefficient compared to modern units. Other signs include: Your home is uncomfortably cold even when the furnace is running. Your energy bills are unusually high compared to previous years or similar homes in your area. The furnace runs almost constantly to maintain the temperature.

Is an old furnace a safety hazard?

Yes. Over time, internal components (like the heat exchanger) can fail, leading to more carbon monoxide (CO). We recommend having any older units inspected regularly and investing in a reliable carbon monoxide detector. Ultimately, replacing an outdated furnace is the only way to eliminate this risk entirely.

Will replacing my furnace save me money?

Yes, in two ways: Lower Utility Bills: Upgrading to a new, high-efficiency furnace can result in 20–40% savings on your monthly heating costs. Avoided Repair Costs: Replacing an old unit saves you from spending money on costly, future repairs, as older units often break down frequently as they age.
