HVAC replacement. The response and bid were quick and seamless. The installers were just so conscientious, funny and fast. The personal experience was excellent. The only glitch was the team did not seem to know the complete rules of replacing the old exhaust and air intake. This required more visits from the inspector. Even with the extra time and effort, I highly recommend My Guy.

Reviews
Bryan Lundstrom came back today to finish the work. He’s so pleasant and goes above and beyond. Was genuinely concerned about making us happy. Best customer service I’ve had in a long time. Great service!
Routine inspection & testing (as part of a their service program) of Lennox system was performed. Issues id’ed included unacceptable weak blower motor capacitor, worn contactor, dirty blower, dirty condenser fins, and dirty evaporator condensate tray. David was highly knowledgeable, thorough, experienced, and dedicated to excellence and customer satisfaction. Also discussed were ways to improve system efficiency and reliability. My experiences with My Guy HVAC is far superior to competing firms I have used and I highly recommend them to others who want high value for their HVAC needs.
