Is your heating and air conditioning system feeling its age? If your furnace isn’t keeping up the way it used to, it might be time to take a look at an upgrade. But should you try to repair it or is it time to replace it? Here’s how to tell:

The Age of the Furnace

Most gas furnaces have an average lifespan of 15-20 years. If yours is approaching its golden years, it's time to take a look at what it's doing for you. The biggest impact of time on new systems is the advancement in technology. Energy efficiency has come a long way, and systems built 20 years ago use significantly more energy than newer units. Some furnaces today are up to 98% efficient, which means that 98% of the fuel they burn goes directly to creating heat for your home.

The Number of Recent Repairs

Have you been spending a lot of time with your HVAC tech lately? Are you getting a little sick of writing checks to give an old furnace some extra time? If you’re repeatedly spending money on furnace repairs, it might be worth your time, and your money, to look at upgrading to a new system that won’t need repairs.

Changes in Your Energy Bills

A real telltale sign of how your furnace is functioning is the number on your monthly utilities bill. If you’ve been watching the cost go up incrementally, month after month, it likely means your system is losing its efficiency. As the HVAC ages, its energy efficiency goes down simply because of use and wear and tear. This decline, combined with the lower energy efficiency ratings of older units, is an excellent reason to upgrade to a new unit that has significantly higher efficiency ratings.

If you’re having trouble deciding whether to repair or replace your furnace, ask an HVAC professional for an analysis of the cost vs. the benefit of replacing your old unit.
