What homeowners say
Vesta’s read
Tri-Tech reads as a craftsman's shop that quietly keeps its customers for the long run — people describe a system installed over a decade ago and serviced without fail ever since. The work itself is the draw: boiler upgrades and zoned-AC conversions described as exacting and on-time, and a willingness to take on the messy, complicated jobs — attic ductwork tangled up with water damage and mold — that others might pass on. Coordinated by an office reviewers name warmly, it's the kind of operation where the install is done right and the relationship outlasts it. Installed a decade ago and serviced without fail since — that arc, repeated across reviews, is the definition of an install done right.

What to check before you hire
Vesta’s plain checklist for HVAC contractors. General guidance about the trade — not a claim about this business.
Ask for a load calculation, not a guess
The right-sized system comes from a Manual-J load calc on your actual home — not 'same as the old one.' Oversized units short-cycle, run loud, and cost more to own.
Confirm the CT license
Heating and cooling work is done under a Connecticut HVAC license. The licensed technician — not just the company name — is who is accountable for the install.
Get equipment, permit, and warranty in writing
Model and efficiency (SEER2 / AFUE), the permit, and warranty registration should all be itemized. A permit and post-install inspection protect you.
Check real emergency response
When heat or AC fails, a callback in hours beats a cheaper shop that goes quiet in a cold snap. Ask their honest after-hours window before you need it.
