Furnace Service or Furnace Replacement: What to Consider

September 11, 2015

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

Furnace replacement is an investment in your home, like most 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 Olde Towne Heating & Air, we know that it can be a hard decision to make, so here are a few tidbits to keep in mind if you’re not sure which way to choose.

1. Furnace Age

This is more than likely 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 furnace is more than 12 years old, it may not make sense to put a lot of money in to repairs when you could be putting that money towards a new system.

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

2. Cost of replacing vs. servicing/repairing

There are always unknowns when it comes to figuring out the cost of replacing versus having furnace service and repairs done, but there are a couple things to keep in mind when considering 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 contains so you’re always saving as much as possible.

Furnace replacement

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

After you calculate the costs of both options, 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 team at Olde Towne Heating & Air are more than happy to help you choose which furnace is right when replacement becomes imminent. Give us a call at 843-485-0967 to find out what makes sense for both you and your budget.
