Is An Old AC Ready for Replacement?

Posted Fri, Apr 22, 2022 in News

Three Signs It's Time For An AC Replacement

AC systems don’t last forever, but there are many options to choose from when replacing them. How do homeowners know when it is time for an AC replacement? Many signs indicate a need for a replacement or repair.

It is not always easy to tell whether a repair or a replacement is necessary, so calling a professional AC technician for solutions is important. Usually, if a homeowner notices loud noises, bad smells, higher electric bills, or a lack of cooling, it’s time to make the call.

Loud Noises & Bad Smells



Some heating and cooling systems are loud, but sometimes loud noises can indicate a major problem requiring replacement. Homeowners could hear clunks and wheezes of air that signal something is wrong with the unit. It is also a red flag not to hear any noises at all. If there isn’t any sound when the HVAC system is kicking in to cool or warm the home, this is a sign that it’s time for a replacement.

What about smells? Often, HVAC systems do not have a scent. However, when there is a smell of burning metal, this is a sign of a problem with the unit and that the AC system is likely not repairable.

Higher Energy/Electrical Bills

As AC systems begin to age, homeowners are likely to see increased electricity usage. This is because the system pushes air quickly and frequently to match the thermostat's set temperature. When this is not possible, it causes major problems and increases the electric bill.

The loss of efficiency that causes higher energy bills could also be due to improper maintenance. Bi-annual maintenance checks by professionals and changing the air filters on time can help the AC run more efficiently. If the proper maintenance is being performed and the energy bills are still unusually high, this signifies a larger problem with the unit. It may not be worth repairing an old AC system as they don’t last forever anyway. Instead, it could be time to install a new energy-efficient AC system.

Other Important Signs To Watch Out for

When deciding if it’s time to replace the AC system in a home, there are other signs a person should look out for. One of the signs is visible wear and tear on the outside. New systems less than two years old should look and feel brand new.

However, if there is rust or a chewed wire, it is time to replace the system or install new wires. Sadly, sometimes repairing one part can cost more than the entire system. If it is cheaper to replace the AC system, then it is best to replace it instead of repairing the broken piece.

Another sign to watch out for is the thermostat no longer responding and communicating with the HVAC system. Sometimes it is simply a quick fix like replacing the thermostat, but other times it is an internal problem that requires professional help.
