Pros & Cons: Should I Service and Replace My Heat and AC Systems Together?

Like many areas of home improvement and maintenance, there's no cut-and-dry answer on whether it's best to replace your heating system and air conditioner at the same time. There are a few factors at play, from system life expectancy to efficiency.

Let's break down the common considerations:

When Does It Make Sense to Replace a Furnace and Air Conditioner at the Same Time?

Central air conditioners typically need to be replaced after 14 years, while modern, energy-efficient furnaces can last 18 years or more. However, most of these systems share an air handler, including the blower, and both systems work better if they have the same capacity and efficiency, as HVAC.com explains.

Many heating and cooling companies offer discounts if you replace both at the same time, and it saves the workers time and you, as the homeowner, from disruption in the household.

So, if both systems are at or near the end of their functionality, it makes the most sense to replace both at the same time if you can afford to do so.

What About Performing Maintenance for Both Heating and AC at the Same Time?

The answer here is easier: Yes, it almost always makes sense to have your annual tune-up done on both systems at the same time, because they use some of the same components. Plus, you only pay one service fee, if your HVAC service charges one. (Pro tip: Check out Guaranteed Service's Comfort Club packages. Some include comprehensive tune-ups on both systems, along with a host of other benefits.)

When Does It Make Sense to Replace Just One HVAC System?

If one system (either your heating or cooling system) still has years of good use left, you might need to discuss the pros and cons of your specific situation with a trusted professional.

HVAC Experts suggests only putting off replacing both if the furnace is less than 10 years old, but you might also want to consider whether both systems are sized correctly and offer an acceptable level of efficiency. You also might want to consider your tolerance for potential future repairs, how long you plan to live in the home, and any available discounts or incentives.

Should I Consider a Heat Pump?

Heat pumps' eco-friendliness has garnered much attention nationwide, and they can both heat and cool your home. Consumer Reports explains that incentives and overall effectiveness vary from state to state, so at least one expert suggests getting a few quotes from trusted local contractors to see if a heat pump is a good fit for your home and property.

As you may have noticed, a theme throughout all these considerations is the trusted contractor.
