Was a no show and then blocked me! So unprofessional
Professional, informative, explained all my options in layman terms. And he showed up when he said he would. And didn't leave until the job was done. And I am very satisfied. Very reasonable when compared to the company that came out first. I highly recommend that you call him first. Thanks Guy I appreciate you 🙏🏾⭐⭐⭐⭐⭐
He got me a brand new HVAC condenser unit for my house very affordable and connected it gave me a new free thermostat that can sync with my phone great awesome guy will definitely hire him again
He was great. He didn't end up doing any repairs to my system but gave me very good information and was very knowledgeable about the system. Informed me that it would be more expensive to fix then to replace. He could of brought me for a loop but didn't. I would definitely recommend him to anyone.
I inquired yesterday about replacing my old Central Air Unit. Received a response from Guy within 15 minutes, he scheduled an appointment for that afternoon. He answered all my questions and only sold me what was needed. He installed the unit today. He was running a little late but kept me informed. He is a very nice guy and looks out for the consumer. Guy we truly appreciate your prompt response and getting the unit installed so quickly.. Thank you! Blanca (Pedro)-Hamden CT
