A home air conditioning system operates more than your car, and like your car, it needs routine maintenance to operate in an efficient, safe and reliable manner. Like all things in life it is less expensive to prevent a problem from happening than fixing the problem once it occurs. Do you really want to be in the dead of summer and have your air conditioner break down, when the cause could have been prevented with a precision tune up?
When your air conditioner starts to degrade, your system will work harder to produce the same result. This means that your electric bills will be higher than normal. Maintaining your air conditioner and heater reduces its degradation rate and allows your equipment to run better and closer to its original condition at a lower cost to you.
