Would you let your car go a year or more without checking or changing oil? Maybe without checking the coolant levels or adjusting air pressure in your tires? Of course not. But many home owners let their air conditioners run for many seasons without the same simple preventative procedures. Many circumstances can rob your unit of precious BTUH's of cooling capacity and many simpler circumstances can cause premature electrical part failures resulting in system failure when you need it the most. Identifying and correcting problems before they become failures and keeping your system in as peek of an operating condition as possible are why you should have that unit checked out and tuned up every Spring and Fall. Our maintenance agreement is designed to do just that. You will recieve two check-up's per year, priority response status on all event calls, a 10% discount on all parts needed, waived service call trip charges and the peace of mind that your system is running at it's possible best. Air Conditioning System Check-Up: Check refrigerant charge and operating pressures. Check voltage and amperage to compressor and all motors. Check air temperature drops and rises across evaporator and condenser coils. Check and lubricate all moving parts. Adjust belt tensions where necessary. Check and test all pressure safety switches. Measure superheat and subcooling levels. Ohm compressor windings. Check compressor contactor points. Check all capacitors. Clean condenser coil if needed. Check evaporator coil. Brush and no-rinse cleaner application if needed Check filters. Clean condensate drain. Clean and adjust thermostat. Heating System check includes: Clean and Adjust Thermostat Check heat exchanger for cracks. Vacuum clean burner compartment and controls. Clean and adjust pilot assembly. Check for gas leaks. Check Flue Pipe. Check filter. Lubricate all moving parts. Inspect draft diverter and induced draft motor. Test electronic ignition. Test all limits. Measure temperature rise. Measure manifold pressure. Test for Carbon Monoxide
