## The honest read

Dynamic Heating, Cooling & Geothermal is a heating and cooling company out of Plainville, as one Reddit commenter put it. On Google it holds 4.7 stars from 316 ratings, and the company says it has been in business 20 years and runs a loyalty program covering system inspections.

A recent customer said Isaiah and Neil arrived early, installed a new furnace and had it running in no time. A recent customer said Steven installed a new furnace and left nothing behind on the floor. Two workers spent 10 hours on a mid-July day installing one recent customer's new heat pump. A recent customer said Alex diagnosed and fixed their problem, and wrote that the company understands geothermal heating and cooling equipment.

A 2026 customer said their geothermal system was struggling when night temperatures dipped below 0°F, and Steven quickly identified what was needed. A 2026 customer came home from vacation to no heat; Claudia found the problem, and given the unit's age they went with a new boiler. A 2024 customer said that, after deciding to look at replacement options for a roughly 20-year-old AC, Nathan came out the next day with several options. That 2024 customer said Isaiah installed a heat pump two days after the original assessment and that the office handled the rebate process.

A 2026 customer said the company charged their mother $1600 for 1.5 hours and rerouted the system to bypass the kitchen when a baseboard heater needed replacing. A 2025 customer objected to a bill of $871.71 for about a half hour of labor, on top of a $99 diagnostic fee, while calling the technician great. A 2024 customer said an after-hours no-heat call came to $1043.00, including a $630.00 after-hours charge. A recent customer said their mother found the pricing considerably higher than other heating and cooling businesses, and that the owner took a personal phone call during the consultation. A 2025 customer said the company would not install dampers named in a furnace contract until shown the contract, and that a heat pump had been left without the right level of coolant by an employee who had since left.

Its Connecticut S1 heating and cooling contractor licence, HTG.0393591-S1, is active, held by Nathan G Noiseux.

**Strengths:**
- Furnace installs — Isaiah and Neil had a new furnace running quickly
- Geothermal service — a 2026 customer said Steven identified what was needed
- Replacement options — a 2024 customer said Nathan gave several options

**Concerns:**
- Repair billing — a 2025 customer was billed $871.71 for a half-hour repair
- After-hours charges — a 2024 customer paid $1043.00 for a no-heat call
- Damper contract dispute — a 2025 customer had to show the contract
