FAQs

How Long Does Ductwork Typically Last?

Ductwork can last anywhere from 10 to 25 years before it begins to deteriorate and needs to be replaced. Deteriorating ductwork can reduce your heating and cooling airflow and performance rates while spiking your energy bills. 

Should I Replace My HVAC Unit Once It’s 20 Years Old?

Yes, most HVAC units must be replaced when they reach 20 years old. When your system reaches this age, you will notice decreased performance rates with increased energy costs, so you should replace the unit before your expenses continue adding up. 

How Much Does It Cost To Replace HVAC Units in California?

HVAC unit replacement costs in California vary depending on the type of system you’re installing. Call Dragonfly Heating & Cooling today to schedule HVAC services in Ontario, California, so we can provide you with an exact quote for your replacement.

Great business and they have employed very polite and capable technicians.
Response from the owner:Thank you so much for taking the time to leave us a 5 star review!
I always request Dustin, who has been doing regular annual maintenance on our mini split AC/heating system in our tenant's unit for years since it first had leaking issues. He takes pride in the work he does and takes his time to do a thorough job. Not many companies work on mini splits, so I was happy to find a reliable company I can call when needed. He was also able to flush my water heater as well and make sure everything was running smoothly. Everyone at Dragonfly has been really friendly and I highly recommend this company.

Dustin did a great job diagnosing and fixing my heater, which had a bad connection. He was professional, efficient, and took the time to explain the issue. He also recommended swapping out the board while we still have time, which I appreciate. Solid service and honest advice—definitely recommend!

Got a concrete patio put in where my condenser units were and Dragon Fly came out to lift my units while the pad was poured. My concrete guy didn’t even realize that was an option. Super friendly and professional staff. Highly recommend these guys.
