Our HVAC technician retired after giving us over 30 years of excellent service. We reached out to Convertible Heating And Air Conditioning based on its excellent HomeStars ratings, and we're more than happy we did. Sean was our technician and inspected our furnace from top to bottom and was also kind enough to wash down our electronic air cleaner coils. Beyond that, he shared his findings with me, showing that everything was within specifications. Best of all from my wife's point of view, he removed his boots except when he was working on the furnace itself. That's service "above and beyond"!
