Should an AC and Furnace Be Replaced at the Same Time?

AC and Furnace Be Replaced at the Same Time

It is likely that the AC and furnace were installed simultaneously when you moved into your new home, and they will typically need to be changed at the same time. In other instances, the AC or furnace will wear out before the other, and you’ll need to schedule the replacement of the older device.

There is a third option, though. What if, even though the other system is still in good working order, you decide to replace both comfort systems because one needs to be replaced? 

Our heating repair in Lafayette, recommend that homeowners should make this decision and profit from it. 

Should my Air Conditioner and Furnace be Replaced Simultaneously?

Our AC repair in Lafayette advise you to consider replacing the furnace if you purchase a new air conditioner. Read on for reasons to consider this:

Age of Outdated Equipment

Whether it’s better to replace your furnace and air conditioner at the same time depends greatly on how old they are. Furnaces, air conditioners, and heat pumps often come with a minimum 5-year component guarantee. The furnace and air conditioning system have a 10-year component warranty.

Combined Labor Charges

Our furnace service specialists in Lafayette believe that the cost of labor is the main factor driving homeowners to replace both their furnaces and air conditioners at the same time. Homeowners will only have to pay for one day of the installation team’s labor by replacing the furnace and air conditioner simultaneously.

The truth is that even while installing a furnace or air conditioner might not take an entire day, the job still costs an entire day of labor. You pay for the labor twice if you divide installing the furnace and air conditioner into two distinct days.

Matching Systems Perform Better

Our HVAC repair experts in Lafayette believe there may be issues if new and old HVAC technology is used. With the wrong components, your system may function less effectively and efficiently than it could.

Installing a new, high-efficiency air conditioner to replace the old one is not a good idea if the furnace is more than 15 years old. You can pay more for heating and cooling your home as their effectiveness degrades.

Savings from HVAC Installation

You can save money by replacing the furnace and air conditioner simultaneously rather than separately. Instead of replacing just one component and discovering that the new equipment won’t function well with the old one, installing the entire HVAC system is more cost-effective.

In the long term, replacing your heating and cooling system will save you money because you won’t need to perform as many HVAC repairs in Lafayette to an old, faulty system.

Moving Out Soon

When replacing their furnace, home sellers with functional air conditioners frequently decide against replacing them. An expensive process goes into selling a house. After thoroughly inspecting everything, an inspector will identify problems that need air conditioning service in Lafayette. Most homeowners wait to replace their air conditioner until a buyer specifically asks for it, has the money to do so, or has a home warranty.

Warranty Problems

You might run into warranty problems if you opt to replace only one component of the system, like the air conditioner, and pair it with a furnace that is 15 years old.

Due to the system’s age, and one component has been replaced while the other hasn’t, there may be warranty issues for heating repair in Lafayette.

More Effective Comfort Controls

Generally speaking, installing a new thermostat only when a new system is installed is preferable. If you replace the heater or the AC, you might be unable to switch to a better thermostat technology.

With a completely new installation, you can get the precise type of thermostat needed to get the most out of your HVAC system.
