AC Repair

Air conditioners are made of multiple complex parts that work together to provide cool air for your home. If one part needs repair and is left unresolved, it can cause other components to fail and lead to expensive repairs or an AC replacement.

Our HVAC technicians can quickly diagnose your AC and make effective repairs to ensure your system runs optimally.

Very quick response time! I noticed the failure of my hot water heater at 7 pm one evening and had a new hot water heater installed and ready to go by 11 am the next morning. Great communication, clear recommendations, and took the time to explain details about the equipment that was ultimately installed.

Ryan H.

We have worked with Comfort Zone for about 4 years and are completely satisfied with the quality of service they provide. They recommended and installed a new AC unit, and provide us an annual furnace and AC cleaning and inspection service. We highly recommend this company for residential heating and cooling needs.
