Okay, so there is one scenario where it’s too late for this service—air conditioning maintenance, that is. If your air conditioner has completely broken down and the compressor is shot, then maintenance won’t do anything. In fact, you’ll probably have to replace the entire air conditioner. This is particularly true if its an aging system as replacing just the compressor, unfortunately, won’t help the rest of your air conditioner last much longer.
A sudden breakdown is a lot less likely to happen in a newer system, or a system that’s had maintenance done on it each year. This is essential—your air conditioning maintenance should be done on a routine basis, no matter the time of year. Sure, it’s most ideal to have maintenance done in the spring, before temperatures reach their hottest. But AC maintenance is definitely one of those areas where frequency means more than timing.
