4 Unforeseen Costs When Replacing An HVAC System

Posted on: 9 December 2020

Do you need to have your entire HVAC system replaced because it is on its last legs? If so, you likely want to know how much it will cost before you have your furnace and air conditioner replaced. However, there are some unforeseen costs that come with having an HVAC system installed that you are not aware of. 

Wiring Replacement

Between your air conditioner and the electrical box on the side of your home is some wiring, and that wiring can sometimes be just as old as your air conditioner. It is always a good idea to have this wiring replaced when installing a new air conditioner to ensure that it can last another 15-20 years. It's a relatively inexpensive cost that can help give you peace of mind that everything is going to last a long time. 

Compressor Concrete Pad Replacement

Another part of the outdoor compressor that needs replacing is the concrete pad that it rests on. If the existing pad has seen better days and if cracked or damaged to the point where it cannot be made level, it is a good idea to replace that pad with a new one. It is much easier to do at the time of the condenser being replaced, and it will ensure that the air conditioner doesn't become unlevel anytime soon. 

Flue Pipe Replacement

The purpose of the flue pipe is to vent carbon monoxide out of your home. While you may think it makes sense to use the old flue pipe, it is a part that can rust over time and cause carbon monoxide to leak into your home. Always make sure that the flue pipe gets replaced when having a new furnace installed, since it's more about the safety of your home than the added cost of replacing the part.

New Ductwork

In a perfect world, your old furnace will be the same size as your new furnace and it connects to the ductwork perfectly. Unfortunately, this will likely not be the case. New ductwork will be needed when connecting to a new furnace. You may find that the new furnace is smaller, so the ductwork needs to be extended downward to get it to connect. There may also need to be some simple rerouting of the ductwork based on where the air exchanger is located on the new furnace. No matter what the reason is, expect some additional expenses for the ductwork material and labor. Learn more about furnace replacement today.
