GONZO Heating & Cooling LLC

A recent reviewer said a different company wanted to replace their entire system and charge thousands, but Wilfredo from Gonzo handled it in 30 minutes, charging only the $139 minimum service fee. GONZO Heating & Cooling is a Newington heating and cooling company with a 5-star average across 171 Google ratings, and its own site lists AC and heating installation, maintenance and repair, water heaters, ductless work and oil-to-gas conversions. On installs, a recent customer said Wilfredo and Andrew installed a Mitsubishi mini-split system in their home, and that it runs quietly and cools the space quickly. A recent customer used the company for installations on their AC, furnace, water tank and oil tank, and said it offers financing options. A recent customer said a new boiler job was completed in one day. Much of the work is service calls. A recent customer said Andrew cleaned their gas furnace and replaced the part the pilot light comes from. Renters waiting on an out-of-state landlord's OK said Will waited, knowing they would otherwise have been left without AC in a heat wave. A recent customer who left a 5am message about a frozen pipe said they were at the home at 9am, and when a furnace quit, a recent customer said Wil was at the house the same day to help repair it. In a 2026 review, a customer said the company swapped out an entire A/C unit and compressor, and that the town inspector who came to close the permit commented on the quality of the work. A 2026 customer with a leaking water heater said Will took on a 2-3 hour job starting at 8pm on a cold night and the job was completed that night. In a 2024 review, a customer whose furnace stopped around 9pm on a weeknight said Wilfredo was at the door within about an hour and a half of the call and had everything fixed within 24 hours.
