Preventative maintenance is key to keep your heat pump running smoothly, efficiently, and with longevity. The experts at Zion Custom Air recommend heat pump maintenance before the coldest winter months in order to keep your Acton home warm all winter long. (We also recommend maintenance for your air conditioning system prior to the season’s hottest summer months). Just some of the important functions of heat pump maintenance are to inspect, adjust, and lubricate all of the pulleys and moving parts, change filters, inspect wire connections and tighten as necessary, clean electrical control panels, inspect for debris that could be inhibiting performance, and much, much more. Our technicians perform maintenance with meticulous precision so that no part of your heating system is overlooked. You can trust our impeccable customized service to ensure proper function, prevention, and/or prediction of future failure or breakdown. Zion Custom Air keeps your budget in mind by providing the best service for the lowest expense. Give us a call to schedule your heat pump maintenance and experience our five-star rated service for you!
