“What an exceptional place to deal with!! My AC went out at the worst possible time of the year. I called Warren-Hay and spoke to Jennifer. She listened to my concerns and had someone out the very next day! The tech that met us was thorough and easy to deal with. We will definitely call them from here on out”
“Excellent service with my brand new 3Ton Trane heat pump install. Both units, outline and inside air ex-changer was replaced with all new copper hoses. The crew was very careful with walking through the house as the craw space door is via indoor. I was so impress with the layout of the job as it look like a piece of art. I highly recommend Warren-Hay Mechanical ! OH, Trane, very nice and quit !”
“Warren-Hay has maintained my HVAC unit for over 15 years and recently replaced the old unit. They schedule visits in a timely manner and are prompt. Staff members are reliable, professional and efficient. I recommend them for all HVAC needs.”
“We had a great experience with Warren-Hay. Our heat pump went out in January. We contacted them for a quote and the same day they had someone out here giving our system a look and had a detailed quote by the end of day. It was an incredibly fair quote, and they gave several options with easily distinguishable pros and cons”
