Our AC Maintenance Services

You can conduct some maintenance on your own. Basic air conditioner maintenance tips include regularly changing the filters and cleaning your vents. 

However, most maintenance services are more advanced. It’s better to leave them to the professionals. Dragonfly Heating & Cooling provides a wide range of intense maintenance services, including: 

  • An accurate diagnosis of all issues
  • Testing the thermostat function
  • Recalibrating the thermostat (if necessary)
  • Checking all electrical components
  • Tightening electrical connections
  • Cleaning the evaporator coil and condenser coil
  • Cleaning the drip pan and condensate drain
  • Checking refrigerant levels and refilling refrigerant if needed
  • Changing the air filters in all AC units

Benefits of Preventative Maintenance

A little maintenance goes a long way. With regular maintenance appointments, you can save money, deal with fewer issues, and achieve better home comfort. 

The benefits of AC maintenance in Corona, CA, include: 

  • Lower energy bills: Regular maintenance improves the efficiency of the system, which reduces the amount of energy it uses. 
  • Longer system lifespan: Regularly servicing your home air conditioning will allow it to potentially last for years longer than systems that don’t receive regular service. 
  • Improved comfort: A serviced AC system will cool the home more evenly and effectively. A dirty vent reduces airflow, so cleaning it will improve the system as a whole. 
  • Stay within warranty: Most warranties require you to have regular service appointments with an HVAC professional in order to stay valid.
