A recent customer said Dave came out for a free estimate and explained the options, and the ductless unit and central AC installation that followed took two days. That customer said the team kept the work area clean and showed them how to use the thermostat and ductless remote. A recent customer whose furnace went out was scheduled a month out, then got a call the day before the install pushing it back another 10 days. When that customer asked David for a sooner date or a small price reduction, they were told no. A 2025 customer said Dave came out the day after they called, and the old systems were removed and new ones installed in one day, with the basement spotless at the finish. That 2025 customer said the first year saved over 50% in electrical and 35% less oil. A 2025 customer said they had used the company for 19 years, that it replaced both their heating and air conditioning system, and named Dave and Brian as the owners. A 2025 customer said Giordano fixed a heater with lots of issues for a more than reasonable price and did not oversell a replacement. A 2024 customer said Bryon fixed a 35-year-old furnace, replacing the blower motor and the wheel. A 2024 customer said the company came out at 9pm to help with a boiler issue. A 2023 customer said leaves and debris were not cleaned from the outdoor AC unit after annual maintenance, though the worker said they had been, and that months of emails about duct work went unanswered. A 2022 customer said another service later found the replacement thermostat was for a 1-stage system on their 2-stage AC, with the second stage disconnected. It holds an active Connecticut heating and cooling licence, HTG.0403053-D1, under Bryon C Miller. **Strengths:** - A two-day ductless install — a recent customer said the work area stayed clean - One-day system swap — a 2025 customer said they were in and out in one day - A 9pm boiler call — a 2024 customer said they came out at 9pm - Repair over replacement — a 2025 customer said a heater was fixed, not oversold **Concerns:** - A delayed furnace install — a recent customer was pushed back 10 days the day before - A wrong thermostat — a 2022 customer said another service found a 1-stage thermostat - A missed maintenance step — a 2023 customer said outdoor unit debris was not cleared ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Its website lists furnace, air conditioner and mini-split installation, repair and maintenance _(confidence: high)_ - [Official Website](https://www.giordanosct.com) — “About (self-reported, verbatim): HVAC ServicesHeatingFurnace RepairFurnace InstallationFurnace MaintenanceCoolingAir Conditioning RepairAir …” - Says it has been in business 47 years _(confidence: medium)_ - [Official Website](https://www.giordanosct.com) — “Self-reported 47 years in business” - Stated service area includes Derby, Ansonia, Milford, New Haven and Southbury _(confidence: medium)_ - [Official Website](https://www.giordanosct.com) — “Stated service area (self-reported): Derby, Ansonia, Bethany, Bridgeport, Easton, Fairfield, Hamden, Milford, Naugatuck, New Haven, Orange, …” - Google shows 4.7 stars from 73 ratings; BBB grade A+ _(confidence: high)_ - [Google](https://www.google.com/maps/search/?api=1&query=Giordano's%20Heating%20%26%20A%2FC&query_place_id=ChIJWWKGn3fg54kRv0dPsfOrIEM) — “Google: 4.7★ from 73 ratings” - [Better Business Bureau](https://www.bbb.org/us/ct/derby/profile/heating-and-air-conditioning/giordanos-heating-air-conditioning-co-0111-73000240) — “Better Business Bureau grade: A+” - A recent customer described a two-day ductless and central AC installation with a clean work area _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT25OV2RIWXhSMnBYUjFaalJWTkNVMnB4YlVwWFEzYxAB!2m1!1s0x0:0x4320abf3b14f47bf!3m1!1s2@1:CAIQACodChtycF9oOnNWdHYxR2pXR1ZjRVNCU2pxbUpXQ3c%7C%7C?hl=en-US) — “5★ I scheduled a free estimate with Giordano’s, and Dave came out and explained all of my options and answer my questions.
