Many AC systems have a long lifespan, and regular maintenance can help them stay in tip-top shape longer. Repairing or replacing your AC is never on the list of things you want to do. But if you see any of these warning signs it might be time to contact a professional:
- Strange Noises -It’s never a good sign to hear strange noises coming from your AC unit. Droning and whirring noises from your home’s outdoor unit indicate significant compressor problems. Grinding and screeching noises from the indoor air handler or outdoor unit are clear signs of a failing blower motor. Rattling, clamoring, whooshing, and banging noises are usually caused by ductwork design problems and can affect your AC system.
- Constant Repairs – If you feel like you’re continually calling your local HVAC company to make repairs, chances are you have a dying AC system on your hands. The cost of constant repairs adds up. You’ll want to compare the cost of your repairs and the cost of a new unit. If you feel like you would save money in the long run by replacing the AC unit, then you should begin pricing out a replacement.
- Old AC Unit – Typical air conditioning systems can last 15–20 years. Some degree of wear and tear is normal, but around year 10, homeowners should begin to keep an eye on their unit for signs that indicate the end of its life.
