The company says it has been in business for 19 years, and its stated service area includes Stamford, Greenwich, New Canaan, Darien, Norwalk and Westport. A recent customer said Tony discussed a persisting overheating issue at the customer's business and installed a new cooling system. One recent customer said two previous companies had caused a leak that damaged the ceiling; Tri Tech diagnosed the problem and solved the issue at a reasonable price. A 2026 customer said they had used Tri Tech to service their HVAC system since moving into the house, and that it replaced the first-floor A/C system and upgraded the boiler. In 2025, a customer said a five-member team installed a new furnace and hot water heater on time and cleaned up afterward. A 2025 customer described an urgent attic ductwork job tied to water damage and mold remediation: Diane sent the foreman, Edwin, provided a detailed proposal within a few hours, and had the team onsite the next day to remove the ducts and replace a rusty pan. In 2025, a customer said Tony installed a boiler and tank in the house. A 2024 customer said the central AC was upgraded to two zones for two floors and the house was left clean. In 2024, a customer said Tri Tech replaced their heating system and described Tony as thorough and communicative. A 2024 customer said Tri Tech installed their HVAC system in 2010 and had serviced it routinely since. When that customer's system died right before a week away over Christmas, the 2024 customer said Scott, the owner, or an associate came by on five different days to restart the unit, and the new system was installed before they left. That 2024 customer said the company did not ask for a penny, not even a deposit, until the system was in and running. A 2024 Reddit commenter in r/StamfordCT said Tony at Tri-tech had done 2 replacements for them. In 2022, a customer who had just moved into the Greater Danbury area said Tri Tech was honest about the diagnosis of the heating system and provided fair pricing. It holds an active Connecticut S1 heating and cooling licence, HTG.0392970-S1, under Tri Tech Mechanical. **Strengths:** - Fast proposal — a 2025 customer got a detailed proposal within a few hours - Zoned AC upgrade — a 2024 customer said the house was left clean - No-heat rescue — a 2024 customer said the new system went in before Christmas travel - No deposit asked — a 2024 customer said payment waited until the system ran ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - 4.8-star Google rating from 38 ratings _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Tri%20Tech%20Mechanical%20LLC&query_place_id=ChIJawIZY1efwokRxKlf12iStyI) — “Google: 4.8★ from 38 ratings” - A+ Better Business Bureau grade _(confidence: high)_ - [Better Business Bureau](https://www.bbb.org/us/ct/stamford/profile/heating-and-air-conditioning/tri-tech-mechanical-llc-0111-14001724) — “Better Business Bureau grade: A+” - Says it has been in business for 19 years _(confidence: medium)_ - [Official Website](http://www.tritechmech.com) — “Self-reported 19 years in business” - A 2026 customer said it replaced the first-floor A/C system and upgraded the boiler _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT25ScWNEQkhXRFphUm5WWlkyUklRMUZ5UzJFeFluYxAB!2m1!1s0x0:0x22b79268d75fa9c4!3m1!1s2@1:CAIQACodChtycF9oOnRqcDBHWDZaRnVZY2RIQ1FyS2ExYnc%7C%7C?hl=en-US) — “5★ Tri Tech is great.
