We’ve always had amazing experiences with Total Comfort, and yesterday was no exception! Their technician, Ricardo, came out and quickly resolved our heater issue. He was incredibly professional, super attentive, and just an all-around great guy. You can tell he genuinely cares about his work and making sure everything is perfect. Highly recommend Total Comfort—Amazing Customer Service!
Total Comfort came to my house (via my new home build warranty). After explaining issue to the tech Ricardo, he quickly got up in the attic, diagnosed, fixed the problem and explained what he had to do. It seemed like only a few minutes and he was gone. I wouldn’t hesitate using Total Comfort again, even after warranty expires with builder . Thanks again to total comfort and my tech Ricardo.
Ricardo showed up to perform a warranty repair on the heater on my new home. He was able to identify and repair the issue on the spot, and corrected a wiring issue left by the contractor who performed the original install. He was efficient, professional, and skilled at his job.
