Top Signs That You Should Replace Your Air Conditioner

Is the summer heat starting to creep into your home? Are you wondering whether your air conditioner needs to be replaced or whether the unit simply needs a tune-up? Because an air conditioning unit can be expensive to replace, you probably want to make sure that yours lasts as long as possible. Unfortunately, everything will eventually wear out and need to be replaced. In order to tell when the time has come, here are some things that you should be watching out for:

Date of last routine maintenance

If you want to keep your air conditioning unit in working order, you should have a professional come out to examine it and replace worn out parts at least once a year. If you have only recently moved into the home, you might not have a full history of prior maintenance and repairs. In that case, a repair technician can give you an estimate as to how long it's been since the last repair. There will be more dust accumulated and more parts worn in a unit that has been neglected than one that has been well cared for. If your unit has been seriously neglected, your only choice may be to have it replaced.

Temperature differences

An air conditioning unit that is starting to break down will leave some rooms warmer or cooler than the rest of the house. Sometimes this can be due to needing to replace the blower fan, other times this can point to more serious issues. Your repair technician can tell you whether or not the hot and cold zones are something to be concerned about or whether they will go away with minor repairs.


A good air conditioning unit should make very little noise, except a faint rumbling or quiet whoosh of air while in operation. If your system rattles and clanks when turned on, it's possible that your ductwork may have come loose over time. If the ducting is in good condition, then the noise may point to a damaged coil in your air conditioner. While these can sometimes be repaired or replaced, the cost may be such that it makes more financial sense to replace the unit with a newer model that is less likely to break down.


Besides parts simply wearing out, energy efficiency is another reason to consider replacing your air conditioning unit. Every year brings advances in air conditioning technology, some years more than others. As a result, brand new air conditioners are going to be more efficient and better at cooling a home than models from even just a decade prior. Even though your five or ten year old unit may still be in relatively good working order, technology advances mean that you may see significant savings on your energy bill if you replace your unit.
