Vesta’s read
What stands out about this HVAC pro — Vesta’s own read of public records and review history, not a paid placement.
Strongly rated
Carries one of the stronger homeowner ratings of the 48 HVAC companies we track across Fairfield County, across a meaningful number of reviews.
What homeowners say
Giuliani is essentially Jack, and the reviews keep coming back to reliability — the thing homeowners say they couldn't find anywhere else. Jack shows up when he says he will (a rarity worth noting, several point out), quotes a fair price, and frequently does the work right then. He's described as a patient educator, walking homeowners through air handlers, compressors, and how long a system has left, so they feel in capable hands. The most telling review comes from a fellow HVAC professional, out of state, who called around and chose Giuliani to care for his own parents — and reported that Jack treated them exactly as he would have.
Summarized by Vesta from 92 public reviews — Vesta’s own wording, not the business’s, and never a copy of any single review.
What they’re known for
Reliable follow-through
Reviewers contrast Jack with others who don't call back — he shows up when he says, then often does the work on the spot.
Patient educator
Jack takes time to explain air handlers, compressors, and system lifespan; homeowners feel "in capable hands."
Quick no-heat response
An evening no-heat inquiry answered first thing the next morning; clean, faster-than-expected installs.
Even an industry peer trusts him
An out-of-state HVAC professional chose Giuliani to care for his own parents — and both were thrilled.
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.
