Last 6 months: 19 reviews, 0 negative. ## The honest read After three other companies treated a failing control board as a reason to sell a new system, a recent customer said Ryan replaced the old board with a couple of relay modules that do the same job. A G Heating and Cooling LLC is a heating and cooling company whose website gives Bethel as its service area and lists HVAC repair, routine maintenance and tune-ups, system installation, air quality assessment and improvement, and ductwork design and installation. A recent customer whose furnace stopped working said the team showed up the same day and got the heat back on quickly. On a hot, humid Friday, a recent customer said the service technician replaced the capacitor on their second-floor AC compressor and got it working. One recent customer said a water heater that needed immediate replacement got a same-day look, and they were back at 8 am the next day to replace it. A customer who had a complete HVAC system replacement said the company responded quickly with a quote and the job was complete 4 days later. When filters were needed for three A/C units, a recent customer said the technicians left to get them and returned instead of scheduling another appointment. A 2025 customer converting from baseboard heaters to a ductless mini-split said Ryan and Kevin got all three interior units to line up at the exterior of the house, leading to the outdoor condenser in a single, uniform line. That 2025 customer also wrote that, while the company was relatively new, Ryan and Kevin had been doing this type of work for over a decade with another company. A 2025 customer replacing a furnace said Ryan's quote was the lowest of three and that they were in and out in one day. A 2025 customer said a Mitsubishi split-system installation was completed in less than 7 hours despite some challenges reaching the top floor. A 2025 customer said that during the work Ryan discovered the home's wiring was not to code and called right away with a solution. A 2025 customer with an oil burner emergency on a weekend said Ryan returned the call immediately and arrived within the hour. A 2025 customer who asked for a heat pump installation quote said Ryan promised one promptly, but follow-up emails and calls after two weeks and again after a month got no response. **Strengths:** - A control board repair — a recent customer said relay modules replaced the failing board - A same-day furnace visit — a recent customer said the team got the heat back on - Next-day water heater replacement — a recent customer said they returned at 8 am to replace it - A neat mini-split install — a 2025 customer said all three interior units lined up outside **Concerns:** - Heat pump quote — a 2025 customer said follow-up emails and calls got no response ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Google shows 4.9 stars from 48 ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=A%20G%20Heating%20and%20Cooling%20LLC&query_place_id=ChIJg2nh1eD2VoIRUqXn_8FTKp4) — “Google: 4.9★ from 48 ratings” - The company's website gives Bethel as its service area _(confidence: medium)_ - [Official Website](http://agheatcool.com) — “Stated service area (self-reported): Bethel” - A recent customer said Ryan replaced a failing control board with relay modules after three other companies pitched a new system _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT210cFJEaE9kVVp5Y1V4VWNHeDJVVWQzZUhsU2RFRRAB!2m1!1s0x0:0x9e2a53c1ffe7a552!3m1!1s2@1:CAIQACodChtycF9oOmtpRDhOdUZycUxUcGx2UUd3eHlSdEE%7C%7C?hl=en-US) — “5★ Ryan and the team got me back up and running after 3 other companies turned my old systems failing control board into a new system sales …” - A recent customer said the team came the same day a furnace stopped working and got the heat back on _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2tkRmJGcERaVEJhU0VJd1IyNWZlRlo1T0VKU1pGRRAB!2m1!1s0x0:0x9e2a53c1ffe7a552!3m1!1s2@1:CAIQACodChtycF9oOkdFbFpDZTBaSEIwR25feFZ5OEJSZFE%7C%7C?hl=en-US) — “5★ Furance stopped working, I called AG.
