The Positives and Negatives of Replacing Your AC and Heating at the Same Time


When it comes time to replace a large unit like your heater or air conditioner, many people wonder if it’s just best to replace both at the same time. The truth is that it often does make sense to replace the two units at once, but that’s not always the case.

Some HVAC experts suggest that in about 70 percent of cases, you should probably replace both, especially if the units are older, if the job is difficult, or if you’re retiring soon. However, a dual replacement isn’t always in order, so today we’re going to talk about the pros and cons of replacing your air conditioner and furnace at the same time.

Air conditioners and furnaces have different lifespans, so it doesn’t always make sense to replace one just because you’re replacing the other.

A furnace will typically last between 20 and 30 years, whereas the average air conditioner has a lifespan of 15 to 20 years.

Therefore, if you’re replacing your air conditioner because it’s 15 years old and your furnace is the same age, then you might want to hold off on a new furnace, because it may still have enough life in it to last as long as the new air conditioner.

However, if the units are both reaching the end of their expected lifespans, you might want to consider upgrading.

But the Cost Will Be Higher

A new furnace could set you back anywhere between $2,000 and $5,000, and air conditioners generally start around $1,000.

Plus, you’ll have to pay installation costs for both units, so you’ll want to talk to your local Louisville, KY HVAC specialist about quotes if you want to consider a dual replacement.

However, You Could Save Yourself Money if the Job Is Difficult

whatprosThere are many factors that play into the cost of an air conditioner or furnace installation, and you could actually save yourself money by replacing both in certain circumstances.

For instance, if you live in a rural area and a technician has to travel a long distance to get to your house for the installation, then you’ll have to pay more for labor.

Similarly, if your furnace and air conditioner are in a hard-to-reach place, the job will be more expensive. In these instances, it makes sense to replace both at the same time, because then you don’t have to pay twice to have an HVAC technician come to your house or to reach an inaccessible area.

Replace Both Systems if You Plan to Retire Soon

retirementMost people live on a tighter budget after retirement because there’s no steady paycheck coming in and less disposable income, and this can make it harder to budget for a major expense like an appliance upgrade. In this case, you should seriously consider replacing both now before you’re relying on pensions and retirement savings for income.

Although it usually makes sense to replace your air conditioner and furnace at the same time, these situations should be evaluated on a case by case basis. For a personalized answer, call your local HVAC technician to assess your circumstances, give you a quote, and help you decide if it’s time to upgrade both units or just one.
