We have been with Comfort Experts for our AC equipment service and parts replacement 10 years. We have had professional service from Comfort, right down to a typical Unit failure replacement handled expeditiously during the heat extremes of summer. Our original unit that was installed for our new house purchased 1999 had a substandard compressor, failing in its 8th year of life. We added a solar heat release vent, installed by your company that improved cooling efficiency greatly. Michael, the tech who came out this time was EXTREMELY kind and professional. Thanks, Michael for hitting a homerun for the team. We won't forget you.
