What homeowners say
Vesta’s read
Giuliani has done the hard thing in an affluent service area — built a spotless reputation on being fair rather than fancy. Across a uniformly strong review body, the recurring pairing is quality work at an honest price, the combination homeowners in pricey towns say is hardest to find. The trust shows up in the details: an evening no-heat call answered at once and handled by morning, patient explanations that leave a homeowner actually understanding their system, and the ultimate tell — another HVAC company owner choosing Giuliani for his own parents. The prestige-zip-code markup is conspicuously missing, and the other HVAC owner who sent his own parents here is the closing argument.

What they’re known for
Excellent work, fair price
The pairing reviewers name most — high-quality installs and repairs without the premium-area markup; even another HVAC owner chose Giuliani for family.
Responsive in a cold snap
An evening no-heat inquiry answered immediately and a technician out first thing the next morning on a freezing day.
Thorough and educational
Jack and Leonard are named for answering questions about air handlers and compressors and leaving customers confident.
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.
