It’s not difficult to decipher whether or not your HVAC system is in need of a tune-up or repair, but it can be a bit more challenging to decide when you should replace it altogether. These are the warning signs of a faulty, bad or broken HVAC system that should be replaced as soon as possible to avoid spending more on your energy bill, or more costly repairs to the system or your home.
Higher Energy Bill
An energy bill that has inexplicably crept up in price could be a sign that your HVAC system needs replacing. Of course, a repair to your HVAC system should take care of the loose kilowatts, but if this doesn’t fix the problem and your bill remains steadily high, it’s more than likely time to look elsewhere for another HVAC system.
Odd Noises Emitting from the Unit
Grinding, grating and squealing noises emitting from your HVAC unit are not normal and should be tended to as soon as possible. The problem could signify a faulty part within the system, or it could just be an overall sign of its age. If you hear odd sounds coming from your HVAC system, find the source of the problem right away. Sometimes the unit needs a repair, and other times, it needs to be entirely replaced due to its age.
You’ve Passed the 10 Year Mark
Ten years is generally how long most parts inside of HVAC systems will last before they show signs of malfunction. Of course, how well you maintain the unit will play a big role in how long the unit will last, but every HVAC system will break down at some point or another. If you notice problems with your HVAC system that’s more than ten years old, it’s highly likely that it would be more cost effective to just replace rather than keep repairing.
Lastly, strange smells are often indicative of HVAC problems. The smells could indicate minor problems, or they could signify more serious problems, such as the wire insulation burning out. Avoiding or getting used to the smell could cause the system to develop more significant problems, which eventually lead to more costly repairs and a possible breakdown. Instead of just accepting the smells or assuming that they are normal or not serious, be sure you find the root of the problem. It could mean that you need to replace your HVAC system!
