Does your furnace need to be replaced?

If your furnace requires frequent repairs

If you find yourself calling for frequent repairs on your older furnace, it may be time to consider a replacement. Often times older furnaces that require a lot of repairs are nearing the end of their lifespan. We recommend calling for a furnace inspection to diagnose your unit and determine when a replacement is needed.

If your furnace is showing multiple signs of aging

Even if you’re unsure the age of your furnace, there are multiple signs that can point towards the potential lifespan remaining. Seeing rust and peeling paint on the housing, weird noises during the ignition stage, running louder than normal, reduced air output, uneven heating, and increased utility bills can all be signs of an aging furnace.

If your furnace is over 15 years old

Most furnaces have a 15-20 year lifespan. If your furnace is over the 15 year threshold, we highly recommend a professional inspection and maintenance call to check on the working parts of your unit. We’ll be able to help prolong the life of your furnace and identify any issues that can turn into failure points in the near future.

If your home is heating unevenly

Older furnaces tend to be inefficient and have poor output compared to newer units. If your home is heating unevenly after adjusting your vent covers, it may be a sign of an aging furnace. If you continue to have issues with uneven airflow or reduced heat, you may want to consider a replacement and talk with an expert today.

The day after Christmas, We got all of our kids back from their other parents' houses and getting set for them to see what Santa did at home and our heat is out. We needed a repair NOW. All of the part suppliers were closed, but Brett was able to talk to other people in his network and get the part and took care of it in one visit. To me, when someone has friends in the business willing to help them help me, that's the sign of someone with a great reputation. He was super friendly, professional, and got our Christmas back on track in no time. Thank you so much, Brett!
