Your air conditioning system needs an inspection if you have had a sudden increase in your energy bill.

Air conditioning systems deteriorate over time, regardless of how well you take care of them. The average AC lasts 10–15 years. You should prepare in advance to cover the cost of replacement to reduce your stress. If you need a new AC and are worried about the cost, we offer financing options on approved credit for installations. Speak with our certified installation team in Corona before buying a new system. We’ll walk you through the process, assisting you in choosing from our great line of cooling products to help you find a new AC that is within your budget and properly sized for your home.


  • Improved comfort
  • Lower energy bills
  • Quieter home
  • Fewer problems


Most manufacturers void your warranty if you don’t schedule routine maintenance for your AC. It only needs a tune-up once a year to stay in good condition. The cost is lower than you may think! Regular maintenance actually helps you save money over the lifespan of your cooling system. It won’t break down as often as it would without tune-ups. Energy bills also stay more consistent. We check the refrigerant level, blower wheel, valves, evaporator coil, evaporator drain, and other important parts as part of our complete tune-up procedure.

Dragonfly Heating & Cooling has you covered in Corona for any AC service you need. Contact us today to schedule an appointment with our team!
