Nero Air Conditioning & Heating Inc.

Nero Air Conditioning & Heating Inc. is a North Haven heating and cooling company that says it has been in business 38 years. It shows 4.7 stars from 290 ratings on Google, and its Better Business Bureau grade is A+. A recent customer said their air conditioning stopped working during the July heat wave, that Nero came out almost immediately with a quote, and that the installation of a new system began and finished over the following two days; they put the cost at $3000 less than another local company. A recent reviewer who has used Nero for seven years said a furnace and AC service found a part not working to full capacity, and that the service with the part replaced came to just over $300; when the AC did not feel as cool afterward, they sent someone out to recheck it. A recent customer wrote that J. Lupo reinstalled a mini-split line cover after siding contractors had removed it. A 2026 customer said their furnace was making a weird noise after a blizzard and that Luis diagnosed and fixed it the same day. A 2026 customer said that after calling five companies, Nero was the only one that agreed to come out the same day. A 2026 customer whose old heater sat in a 3rd floor crawl space said the workers removed it and installed a new unit, and that project coordinator Tony Struzinski helped them obtain a rebate from the local utility company. A 2026 customer wrote that another geothermal company had quoted 9k for a $437 repair job. A 2022 customer said Nero replaced a full HVAC system at their old condo, a job that needed a crane to get the system on the roof, for $6000 less than Viglione quoted. A recent customer with a boiler in a 4 unit condo association said they paid $134 for a visit and that a promised quote for system-wide issues never arrived after five months. A recent customer said two LG heat exchange units Nero installed less than a year earlier took about an hour to produce warm air in winter, and that they were charged $138 when a technician spent less than 10 minutes clearing what he said was a clogged outdoor drain after water leaked from a vent. A recent customer said a technician told them their boiler needed a new gas valve, that a Southern CT Gas Co. technician then found a loose wire, and that they were waiting on a return call about the diagnosis fee. A 2023 customer said that almost five years earlier Nero quoted over $6K for a new HVAC system, and that another HVAC business told them the old one had more years left. It holds an active Connecticut S1 heating and cooling contractor licence, HTG.0407900-S1, under Michael Nero Sr.
