Maintaining your air conditioning system is the one thing you should do to protect your investment and ensure that your system stays running for many years to come. People often discount the importance of routine maintenance, this is a grave mistake. Think of it like this, you wouldn't buy a new car then never take it in for an oil change, would you? Essentially, that is what you are doing by not having us out for a system tune-up. A recent study showed that running an A/C system though one summer in Florida is very similar to the wear and tear of driving a car 100,000 miles.
