I recently went under contract to sell my home and learned that I needed to replace my HVAC system. Courtesy Plumbing has been maintaining my system the past 4 years, so I called to get a technician out to evaluate and give me an estimate. Pablo was amazing. We had experienced minor problems in the past that were due to a too-large AC system. He performed load calculations to show the size we should have for maximum efficiency, comfort and savings. Pablo was very technically knowledgeable, professional, and gave me a comprehensive quote that was competitive. Moreover, he tentatively scheduled a date/time for the replacement. As it turned out, my Buyer ended up wanting a credit rather than the actual replacement (so he could use his plumber) but I would highly recommend Courtesy Plumbing - and Pablo - to anyone looking for a new system and an honest evaluation!
