Preventive HVAC Maintenance



If you live around Phoenix, we don’t have to tell you how hot it gets in the summer, or that consistent preventive HVAC maintenance is important well into the spring and fall months. An unexpected and inconvenient breakdown due to lack of maintenance is at best a temporarily hot and stuffy inconvenience. More often, though, it also means potentially expensive repairs and much longer periods of discomfort.

At Morehart Air Conditioning & Heating, we help you avoid this cost and hassle with preventative maintenance plans for all your residential or commercial heating and cooling systems. We don’t like to call our visits tune-ups, because that implies changing or installing new parts in your home or office air conditioning and heating system. Instead, our simple and affordable preventative maintenance services provide regular, complete system inspections and cleanings. A certified technician from Morehart Air Conditioning & Heating visits your home or office on a set schedule—usually in the spring and fall to prepare for the upcoming season—and makes care recommendations per the manufacturer’s guidelines based on the model you own and the results of the inspection.

Benefits of a preventative HVAC maintenance plan

Preventative maintenance plans are a great way to save you time and money, as you will receive priority service and discounted pricing while keeping your HVAC system in good condition and functioning consistently. In fact, most systems with a manufacturer’s warranty actually require regular maintenance for the warranty to remain valid. If your air conditioning unit breaks down and you haven’t had a professional check it recently, your warranty may be void and you’ll be forced to pay for the repairs out of pocket.
