What homeowners say
Vesta’s read
At a scale of feedback few HVAC shops in the county match, 20/20's signal is steady and specific: this is the company for the homeowner ready to leave oil behind. Conversions to heat pumps come up again and again — replacing oil heat outright or pairing a pump with an existing burner — always with the same note that the equipment was solid and the price competitive. What turns that into trust is urgency: when a system fails, 20/20 tends to move while competitors are still quoting lead times, and when an install needs a second visit, they come back and make it right. The bigger decision — modernizing how the house heats and cools — is exactly where the depth of this record pays off, and the explanations come with it.

What they’re known for
Oil-to-heat-pump conversions
Homeowners describe replacing oil heat with heat pumps — and supplementing existing oil burners with them — at prices they found competitive.
Moves when others can't
Repeatedly installs AC and replaces failed equipment on short notice, including a hot-water heater the day before a holiday.
Technicians who explain
Jake, Ben, Dylan and Kurt are named again and again for patient diagnosis and clear advice on running the system.
Stands behind the install
When an installation had early trouble, reviewers note the team came back and made it right rather than walking away.
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.
