Avallone Heating and Cooling

Avallone Heating and Cooling LLC delivers heating and cooling services across the New Haven metro area, earning a perfect 5.0-star rating from 138 verified client reviews. Founded in the Elm City, this locally operated contractor specializes in furnace repair, boiler service, and AC installation for residential customers throughout New Haven, West Haven, and surrounding shoreline communities. Homeowners consistently praise the team for responding to emergency calls within hours, not days, ensuring families stay comfortable during the region's demanding heating and cooling seasons.

What distinguishes this contractor is their commitment to resolving problems completely during the first visit. Reviewers describe technicians who stayed longer to verify systems operated correctly before departing, even when discovering secondary issues like a compromised pipe or water heater malfunction. The crew arrives with diagnostic tools ready, explains each repair step clearly, and provides transparent guidance on preventive maintenance. Rather than recommending unnecessary replacements, they focus on targeted repairs that restore existing equipment to reliable operation.

Customer stories reveal the hands-on expertise behind the five-star reputation. One Saturday, a homeowner woke to a dead furnace hours before a winter storm arrived; Marcello reached the residence within an hour, explained his findings, and had heat restored before darkness fell. Another reviewer described a complex boiler problem that two prior contractors misdiagnosed; the Avallone technician identified a frozen pipe supplying the system, repaired it on the spot, and ensured proper water flow before leaving. These scenarios illustrate why New Haven residents call Avallone first when heating systems fail.
