Edgerton, Inc. is a heating and cooling company that, by its own count, has been in business for 70 years. When a Guilford, CT customer asked it about a mini-split, the technician walked through a detailed comparison of a mini-split against a full system with air handlers and ductwork, and the customer chose a Bosch heat pump system, writing that the installation team arrived on time every day and finished exactly on schedule. On Google it holds 4.8 stars from 605 ratings, and its BBB grade is A+. A customer who called at 7 pm had a tech at the house by 8 PM, with the repair part on the truck. Ramon found a geothermal A/C problem, a condensate overflow tank not emptying, and fixed it in about half an hour, a customer wrote. Andrew C came out after hours to fix two HVAC units that had been turned off during a duct cleaning by a different company, and that customer decided to switch their contract to Edgerton. A customer said four installers, Jon, Colby, Gareth and Ryan, completed a new air conditioning system in one day. A customer who booked gas fireplace service said the technician explained the situation clearly and made adjustments as needed. A recent customer who had a 5-zone Trane heat pump system installed said the mechanical installation mostly went fine, but a temperature sensor was installed crooked and a thermostat was mounted so high it had to be looked up at; both were relocated after a complaint. That customer wrote that the system works well but that "The service I've received has been atrocious." In a 2023 review, a customer said a mini-split Edgerton installed in 2015 lost refrigerant almost every year and that its compressor failed for good in 2022. A 2023 customer wrote that a $300 Freon charge on a six-year-old system came as a surprise. Connecticut lists its S1 heating and cooling contractor licence, HTG.0302765-S1, as active, held by Edgerton Inc.
“They were all very knowledgeable about heat pumps and aware of their pros and cons, none tried to steer us away.”
“Tools were reported stolen from two unlocked work vans at Edgerton Inc., 786 Main St., according to a police complaint filed Thursday.”
