Giuliani Air Conditioning & Heating

Giuliani Air Conditioning & Heating earns a 5.0-star rating from 84 Greenwich-area homeowners who consistently praise the team's technical skill and transparent communication. Operating under round-the-clock availability, the company handles emergency repairs, system replacements, and preventive maintenance across Greenwich and neighboring communities in Lower Fairfield County. Jack Giudice leads a crew of NATE-certified technicians who treat every home as if it were their own, showing up in marked vehicles and working cleanly no matter the job scope.

What distinguishes Giuliani from larger regional competitors is their hands-on approach to every project, from boiler replacements to smart thermostat integrations. The company installs leading brands including Nest thermostats, a detail that speaks to their willingness to tackle newer technologies many area contractors sidestep. Homeowners particularly note the team's reliability: when Jack commits to a timeline, he delivers that same day or the next, something reviewers emphasize is rare in the service trades. This accountability extends through the entire job, from initial estimate to final walkthrough.

Customer stories reveal the team's versatility under pressure. Michelle Starr's review describes a compressor and furnace replacement where Jack explained every option without pushing upgrades. Steven O'Hara needed three Nest thermostats installed, a job other contractors repeatedly declined, and Jack arrived on time, quoted fairly, and completed the work in a single visit. Mark'ssystem replacement showcased quiet operation and measurable efficiency gains within weeks of installation.
