Should I Replace My Furnace and Air Conditioner at the Same Time?

If your entire HVAC system is over 10 years old, it’s best to replace your furnace and air conditioner at the same time. It’s not necessary to replace your furnace and air conditioner together. However, replacing your furnace and air conditioner at the same time is often a cheaper and more effective solution in the long run.

Down to Business

Replacing all elements of your HVAC unit at the same time will help your system work better, longer, and save you money. Get a jump start on your furnace and AC plans with this list of why it’s better to replace older HVAC units together.

Optimum Efficiency

Your HVAC system works hard. It regulates the temperature in your home, running non-stop to keep you and your family comfortable. Replacing one part of your HVAC unit without upgrading another can impact efficiency: like a race car with one new tire and three old ones, your system will start to lag.

A lagging system leads to less effective heating and cooling, and it can slow down or break other parts of your unit. So when half your system is off to the races and the other half is still warming up, problems will occur. Don’t let your new furnace run laps around your old AC (or vice versa) — If your furnace and air conditioner are both older than 10 years, it’s time to replace them.

Bang For Your Buck

Your heating and cooling systems don’t need to be replaced at the same time, but if you don’t opt for the double upgrade, you’re simply putting off the inevitable. Is that a disaster? Not necessarily. But keep in mind that you’d be paying twice the labor cost, since it would be two separate jobs. Replacing heating and cooling separately requires two separate evaluations and two visits to your home. So while replacing half your HVAC may be a cheaper expense right now, it can rev up your long term expenses.

Here’s Your Sign

Still not sure if you want to greenlight your entire HVAC replacement? With a system that’s 10 years or older, you shouldn’t be afraid to step on the gas. But if you’re a new driver, consulting an experienced contractor can get you on the right track.
