Dependable Heating & Air's NATE-certified technicians service all makes and models of air conditioners, ensuring each home is saturated in chilly comfort during the sweltering summer months. During each tune-up, the frigid-fixers check all thermostat settings, tighten all electrical connections, measure motor voltage and current, and lubricate all mobile parts to cut down on friction and other performance hindrances. Next, they'll inspect the condensation drain and check system controls, forcibly removing any flow-clogging Pooh bears before cleaning the evaporator and condenser coils, cleaning and adjusting the blower components, and checking the refrigerant levels, replacing thawed turkeys as needed.
