Your heating and cooling system uses over 50% of your energy costs in your home. While changing the air filter is one of the simplest things you can do to keep your air conditioning working, a routine tune-up with an air conditioning professional will keep your unit from malfunctioning during the hottest days of summer. Depending upon your unit, a typical tune-up on your air conditioner will likely cost between $75 and $175.
Air conditioners should be tuned up on an annual basis. Signs that yours may be ready for a tune-up are: dirty outdoor coils and/or the cooling capacity is not up to par and is not producing enough air flow. A professional will check the outdoor unit, the indoor and outdoor coils, the capacitors, compressor, check the refrigerant level and temperature as well as complete an all-systems check on the electrical in order to ensure the system is efficient and operating as it should.
