Pro Tips on How to Extend the Life of Your Furnace


Furnaces have an average lifespan of 10-15 years. Unfortunately, having to replace a furnace before even the 10-year mark is not unheard of. Homeowners who have had to replace an HVAC system early have one overwhelming question: “What could I have done to avoid an early replacement?” 

Although furnaces that need to be replaced that early have been grossly neglected, the best way to make sure your furnace lasts for 15 years or longer is to take excellent care of it. Let’s go over 8 pro tips on how to maximize the lifespan of your furnace.

1. Never Skip Annual Maintenance

The 10-15 year lifespan for furnaces only applies to furnaces that have received regular, annual maintenance performed by a professional HVAC company. In fact, skipping furnace service in Baldwin, PA can decrease a furnace’s lifespan by as much as half! We highly recommend joining our Maintenance Club to make scheduling maintenance as easy and stress-free as possible.

2. Clean or Replace Filters Regularly

We know that cleaning a reusable filter or putting in a new disposable one can slip your mind. Whether you need to put a reminder in your phone or write it down on a calendar, a clean air filter is essential for keeping your furnace’s interior parts clean and clear of dust, dirt, and debris that can hinder its performance and reduce its lifespan.

3. Get Repairs Done Immediately

Whenever you get a repair estimate, take care of it promptly. You may want to get other estimates for a costly repair but don’t delay too long. The longer a furnace runs when it’s struggling with performance, the more wear and tear it’ll incur. 

4. Monitor Humidity Levels

Excessively dry winter air can affect the performance and longevity of your furnace. Low humidity makes you feel colder than you actually are, prompting you to increase the temperature. Use a humidifier to balance your home’s air or better yet–consider a whole house humidifier. 

5. Insulate Ductwork 

Insulating ductwork in unconditioned spaces such as attics, crawl spaces, or basements can prevent heat loss and reduce strain on your furnace. 

6. Set the Thermostat Appropriately

We know it can be tempting to bump up the thermostat when it’s freezing outside. Instead of increasing the thermostat, put on an extra layer of clothes to keep you warm. Investing in a smart / Wi-Fi thermostat can also help you learn about and monitor your heating patterns.

7. Weigh the Pros and Cons of Gas Vs Electric Furnaces

Although electric furnaces tend to last longer than gas furnaces, electric furnaces may need to be run longer. Contact us to discuss which furnace to purchase if longevity is a top goal.

8. Stick With One HVAC Contractor

Stay with one contractor who’ll become familiar with the ins and outs of your system. At Boehmer Heating & Cooling, we’ve been in business for more than 90 years so you know that we’re here to stay.
