1. CONDENSER COIL will be inspected and cleaned as required. VALUE TO YOU - Dirty condenser coils raise refrigerant pressure higher than needed, increasing your electrical bill.

2. EVAPORATOR COIL will be inspected. VALUE TO YOU - Evaporator coils become dirty because air filters only collect a portion of the particles in the air. Even a small amount of dirt can decrease efficiency and increase operating costs. This is also a major cause of compressor failure. Customer should replace properly sized air filter every month.

3. BLOWER WHEELS will be inspected. VALUE TO YOU - Dirty blower wheels reduce air flow, causing longer operating time and increased cost. This problem can lead to lost comfort and compressor failure.

4. REFRIGERANT CHARGE checked by super- heat/sub cooling method. VALUE TO YOU - A low or high refrigerant charge can easily go unnoticed and increase operating costs. An improper charge can also cause it to shut down.

5. AIR FILTER will be replaced at customer’s option. VALUE TO YOU - A restricted air filter can cause your air conditioning unit to waste energy and shorten the compressors life.

6. LUBRICATION of motors and bearings. VALUE TO YOU - Improperly lubricated rotating equipment will eventually fail.

7. THERMOSTAT will be checked and calibrated as required. VALUE TO YOU - Improperly calibrated thermostats allow the unit to run longer than necessary. Every degree your air conditioning operates below 78 degrees can add 5% to 8% to the cost of cooling.
