For air conditioners, it is advisable to schedule an annual service tune-up and cleaning, in the spring. Our skilled technician will inspect and clean the connections, coils, blower components, lines, refrigerant, drain, fuses, and thermostat(s), and lubricate all moving parts. In between service visits, you can help maintain your unit by clearing any yard debris or vegetation from the top and sides of your outdoor air conditioner and covering it with a tarp or air conditioner cover during the winter.
