After years of many issues with our HVAC system, Adon made a quick diagnosis and outlined clear and simple thermostat instructions after just one visit. Not only was Adon thorough and concise, he was also incredibly aware of our needs and was extremely patient. I look forward to his visit this week when he comes to install the part. He assured me that if I had any questions, he would go over everything again with me until I understood it 100%. I have never had such a positive experience with a technician! Five out of five stars, this human is absolutely wonderful.
