Preventative Maintenance

Keep your air conditioning unit in tip top shape with scheduled maintenance. Regular maintenance results in more reliable operation, higher operating efficiency, and lower energy and repair bills.

Our seasonal preventative maintenance check-ups include a 25-point air conditioning inspection and tune up. We recommend a check-up before turning your air conditioning system on in the spring and a fall check-up for your heating system. Our air conditioning maintenance tune up includes:

  • Inspect components for operation and safety
  • Change A/C filters for improved efficiency and air quality
  • Test your system
  • Identify current or potential problems to fix now
  • Energy analysis for aging systems
  • Protect your rights to manufacturer warranty claims

When you are part of our Maintenance Program, DiPietro will automatically remind you when it’s time to service your equipment every season.

Customer Feedback

“In the height of a recent heat wave, my AC ceased working. I was recovering with a broken foot, and was housebound (and suffering in the heat). I called my regular guy, and he couldn’t get to me for a week. Another company I called said that the earliest they could get to me would be in three days. I called DiPietro, and the pleasant woman who manned the phones, said that she would get a service person to me that day. He showed up as promised, and got my AC working. I now have a new HVAC service provider! I take my hat off to them for responding in a way that will build their business, rather than lose customers.” From Yelp, summer 2014.
