5-Star Customer Experience
Great customer service. Polite, professional, prompt. They did what was needed and didn't try unnecessary upselling. This was the first time we used Dunco, but it will be our go-to for HVAC from now on.
Stephen Phillips
Dunco installed a new, high efficiency A/C and furnace today to replace our existing, 21 year old system that was original to the house. The entire process - from obtaining a very specific and detailed bid to the installation process was incredibly smooth.
Nicole H.
We recently replaced our HVAC system with Dunco and had a positive experience from beginning to end. Joe was prompt, professional, knowledgeable, concerned about our needs and expectations and provided a reasonable quote within the same day.

F.A.Q.
Questions? We’ve Got You Covered
We recommend you have your AC unit serviced at least once a year, typically in the spring before the cooling season begins. Regular maintenance can help ensure your system runs efficiently and prevent costly breakdowns.
Common signs that your AC unit may need repair include insufficient cooling, unusual noises, frequent cycling on and off, higher energy bills, and leaking or excessive moisture around the unit.
To improve the efficiency of your AC system, ensure regular maintenance, clean or replace air filters monthly, keep the outdoor unit clear of debris, use a programmable thermostat, and consider sealing and insulating your home's ducts.
- The average lifespan of a residential AC unit is typically between 10 to 15 years. Proper maintenance can help extend the life of your system, while neglect can shorten it.
- You should consider replacing your AC unit if it is over 10-15 years old, requires frequent repairs, no longer cools your home efficiently, uses outdated refrigerant (like R-22), or if your energy bills have significantly increased despite regular maintenance.
