Should You Replace Your Furnace and AC at the Same Time?


Many homeowners and business owners wonder if it is best to replace a furnace and air conditioner at the same time. There are many factors to consider before determining if this is the way to go.

Why Do Some HVAC Techs Recommend All-In-One Replacement?

Many people have been told by HVAC technicians that it is better to replace the entire system at one time. While this may seem like a good idea that saves time, it can present a few problems. HVAC contractors initially recommended all-in-one replacement at the urging of the Air Conditioning, Heating and Refrigeration Institute (AHRI) following the aftermath of Hurricane Sandy in 2012. In this instance, a total replacement made sense as it was recommended for homes and businesses that had sustained extensive damage. However, for the average home or commercial building, a complete replacement may not be necessary.

Benefits of All-In-One HVAC Replacement

Although replacing your furnace and air conditioning unit simultaneously may not always be necessary, there are some benefits to doing a total overhaul. Some of the common reasons for total replacement include the age of both your furnace and your air conditioning unit, health concerns of the people who occupy the structure, and financial incentives offered by manufacturers.

The first major advantage of an all-in-one replacement is cost savings and convenience. By replacing both HVAC components at the same time, there’s no need to have technicians in your home for multiple installations. Additionally, newer models are extremely energy-efficient, providing cost savings.

Another factor is the age of your furnace. While the age of the air conditioner is important too, there is a sweet spot with furnace age that makes it ideal for an all-in-one replacement. If your furnace is over 15 years old, it will need to be replaced soon. When replacing a furnace, your air conditioner’s evaporator coil and other components will need to be detached from the system anyway, so it makes good financial sense to replace them both.

If you have family members with respiratory issues or allergies, it may be a good idea to replace both units together. Older air conditioners paired with newer furnace units can create an imbalance in the HVAC system that will aggravate health issues as well as tax the components of the older unit.

If you are interested in maximizing energy efficiency in your home or businesses, a total replacement makes sense in this case. Older furnaces can work well with new, high-tech air conditioners but the installation and maintenance requirements can be challenging. Only highly skilled HVAC technicians can get older and newer equipment to function properly. The furnace’s blower motor is what drives the cool air from the air conditioner through your space’s ductwork, so an older furnace simply won’t function as well.

Drawbacks of Replacing Your AC and Furnace at The Same Time

It’s not always necessary to replace your furnace and air conditioner at the same time, and there are some downsides to an all-in-one replacement.

One of the biggest downsides has to do with the average lifespan of both your furnace and your air conditioning unit. While some contractors may recommend a total replacement, if your furnace has a lot of life left, you may not need to have it replaced. Replacing a perfectly working furnace will cost you more money and is not necessary unless special circumstances exist. Although there are cases where an older furnace and a newer air conditioner (or vice versa) may present problems, this is only true some of the time. Have your system evaluated by an experienced HVAC technician who can give you more insight into your options.
