When Should I Replace My Air Conditioner?
Air conditioners don’t last forever, and knowing when to manage with AC repair and when to upgrade an old unit can save you considerable money in the long run. While the up-front cost will always be higher than a repair, you must consider the monthly utility bill savings from a more energy-efficient unit and avoid the cost of calling a technician for constant repairs.
Some key signs that you should consider installing a new AC unit include:
If your technician quotes you a repair price of at least half the cost of a new unit, you should seriously consider scrapping your current AC and upgrading to a new one.
Air conditioners typically last between 15 and 20 years with proper maintenance and care. Once your unit approaches that age, you should start researching new units and consider upgrading.
While air conditioners tend to be far from silent, if yours ever starts to make new noises like banging, whirring, buzzing, clicking, etc., you should turn it off immediately and call a professional to take a look and ensure a significant component isn’t broken.
While it's common for condensation to form on your air conditioner's exterior, it should never drip or leak inside. This could be caused by a coolant leak, which can be seriously dangerous to you, your pets, and your family.
