Scope of work
What homeowners hire them for
Everything above is drawn from public reviews and Connecticut state records — nothing self-reported, nothing paid for.
The HVAC company that picks up when no one else will — Upul at Green Mechanicals is named for same-day emergency rescues on the coldest day of the year, honest no-upsell diagnoses, and Mitsubishi ductless installs with rebates explained.
What sets them apart
Specialty capability confirmed in the review record — not every HVAC Vesta tracks takes this on.
Ductless mini-splits
One of the few HVAC companies we track who specialize in ductless mini-splits — the answer for additions and homes without ductwork.
What homeowners say
Vesta’s read
Green Mechanicals has built its recent reputation on the moment every other company goes quiet — a deep-freeze heating emergency with ten contractors ghosting, and the one outfit that actually shows up the same day. That responsiveness is the loudest note in the reviews, but the more telling one is what happens once they arrive: homeowners describe being told the truth about what does and doesn't need doing, prices that aren't padded, and patient walk-throughs of ductless options and rebates. It reads as a contractor competing on honesty and availability rather than salesmanship. In a deep freeze with ten contractors ghosting, one showed up — and the honesty homeowners met on arrival is why the story keeps repeating.
Summarized by Vesta from public reviews · analyzed July 2026 — Vesta’s own wording, not the business’s, and never a copy of any single review.
What they’re known for
Answers the emergency others ignore
Came out same day on the coldest day of the year after 10+ companies ghosted; same-day AC rescues in peak summer heat.
Honest, no unnecessary work
Reviewers repeatedly say Upul does only what’s needed, won’t inflate the price, and walks them through options step by step.
Ductless & rebates
Mitsubishi ductless installs with patient guidance through equipment choices and clean-energy rebates.
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.
