When Should You Repair or Replace Your Furnace?

October 4, 2021 | Blog

With the winter season approaching, you might be ready to fire up your furnace again. When starting your furnace again after the off-season you might notice a few hiccups as your system kicks on. However, if these problems persist and your furnace just isn’t working or heating your home like it used to, it might be time to consider professional furnace repair or replacement. 

When it comes to resolving issues with your home’s furnace there are a lot of factors to consider. Before seeking out professionals, like our trained technicians at Big Mountain Heating & Air Conditioning, you might want to first ask yourself whether you’re looking to get your furnace repaired or whether you might want a total furnace replacement. 

Repairing Vs. Replacing Your Furnace

How Well is Your System Functioning?

One factor to consider when trying to determine if you need a furnace replacement or just a repair is how much or how well your system is functioning. If your furnace is still functioning and just isn’t heating your home consistently or well you might only need furnace repair services. 

On the other hand, if your furnace isn’t functioning at all and you suddenly find your home freezing, you’ll probably need a new furnace and should consult a professional for a replacement as soon as possible.

How Old is Your System?

Another factor to consider when determining if you should repair or replace your furnace is your system’s age. In general, even with regular professional maintenance, a furnace’s efficiency declines each year. A furnace that hasn’t been well-maintained will also decrease in efficiency even faster. 

On top of a steadily declining efficiency, the average lifespan of a furnace is only 15 years. So, if your furnace is over 10 years old and you haven’t kept up with regular maintenance it might be time for a replacement. Taking the replacement route for an older system can also save you money in the long run!

Still Not Sure if You Should Replace or Repair?

If you’ve thought about and considered your system’s level of functioning, efficiency and age and still aren’t sure whether you should pursue furnace replacement or repair, you should seek out the help of a professional. Our technicians can inspect your furnace and advise you on whether you should choose a furnace repair option or buy a new furnace altogether.

Signs That Your Furnace Needs To Be Repaired or Maintained

While it might be unclear whether you should get your furnace replaced or repaired, the following signs indicate that there is definitely an issue with your furnace:

  • Your system is difficult to start.
  • Inadequate heat/diminished heating capacity around your home.
  • Air isn’t flowing properly from your system’s registers.
  • Water around your furnace/visible leaks.
  • Strange or new noises are coming from your furnace.
  • Abnormal or foul odors are coming from your furnace.
  • Your system’s pilot light is discolored. 

If you notice any of the above signs, you should seek out professional help before these issues develop into bigger, more expensive and inconvenient problems.

What Our Customers Have To Say

Good Rebates

This is a review for a complete HVAC system replacement from Big Mountain. I started at the SMUD website looking for the best rebate program and found a list of contractors there. I vetted out companies that had a lower number of completed jobs per the SMUD rebate program data.

Very Professional

Had my A/C go out yesterday, called Big Mountain today and they had a serviceman in my area of Lincoln, he was here within a half hour and fix my unit in a very professional manner, and the cost was reasonable. I was very impressed with the company and the serviceman.

I had a appointment with them between 1-3 and one of their staff members called me and kept me updated when they will arrive which was nice. Steve arrived on time and was really nice for explaining what could the cause be. My ac fan was working but cool air wasn’t coming out.
