Best boiler installation pros near Shelton, CT

"Yes, one day install conversion from tank electric to tankless gas with water softener"

"I always trust Chris as my technician to deliver superb service re: my furnace/boiler, hot water tank, split A/C system, and dehumidifier. It's a pleasure to greet him semi-annually, since he's courteous, pleasant, and professional, and since he answers all my questions re: my heating and cooling systems. I trust this talented tech being inside my home and tuning up all these systems. Kudos to Tyler Heating & A/C for hiring Chris as its employee."

"Prompt, efficient service --- Technically knows gas furnace products --- More importantly knows the economics of keeping up with repairs on a 30 year old unit vs going with a new unit --- Not a sales pitch -- just facts ---- Went new and the cost including nicely done installing was much lower than I originally thought it would be .

"Brian and his team were amazing. Even after months of delay on my part, they were attentive when I was ready for the project and they worked to get all of the equipment (new Furnace, AC, and Water Heater) in and installed in one day. They were efficient and very professional. I would definitely, and have recommended them."

"Knowledgeable and friendly from initial consultation to installation. Very happy with Air Inc."
