Furnace Service or Furnace Replacement: What to Consider

September 11, 2015

Cooler weather is becoming a real possibility in St. Louis, which means one thing: it’s time to arrange for your furnace service. However, it may not be that straightforward if your system is climbing up there in age and has been causing difficulties over the last few years.

Furnace replacement is an investment in your home, like nearly all other home improvement projects are. So how do you know if you should buy that new furnace now or simply get your annual furnace service done?

At Morgner Inc. Air Conditioning & Heating, we know that it can be a tough decision to make, so here are a few tidbits to keep in mind if you’re not sure which route to choose.

1. Furnace Age

This is probably the biggest factor in to your decision, as furnace technology has improved a lot of things, from energy efficiency to the amount of noise it gives off. If your equipment is more than 12 years old, it may not make sense to put a lot of money in to repairs when you could be applying that money towards a new system.

However, the typical 12-15 year lifetime of a furnace doesn’t mean it can’t work well beyond that. If furnace service has been routine and it has been properly maintained, you may be able to go beyond that 12-15 year average.

2. Cost of replacing vs. servicing/repairing

There are always unique circumstances when it comes to figuring out the cost of replacing versus having furnace service and repairs done, but there are a few things to keep in mind when comparing the two.

Furnace service

  • Get multiple estimates to ensure you’re getting the best deal.
  • Keep track of when your warranty expires and note what it covers so you’re always saving as much as possible.

Furnace replacement

  • Furnace size will be calculated by the size of your home.
  • Cost will fluctuate depending on the level of energy efficiency you’re searching for.
  • The higher the AFUE rating, the greater the chance for energy savings.

After you calculate the costs of both routes, keep this helpful tip in mind: if your furnace service and repair is going to cost 1/3 or more of the cost of a new furnace and your system is between 12-15 years old, furnace replacement may be the better long-term option.

Of course, these are only a couple of the variables, but the experts at Morgner Inc. Air Conditioning & Heating are more than happy to help you choose which furnace is right when replacement becomes necessary. Give us a call at 314-262-4541 to find out what makes sense for both you and your budget.
