The company describes itself as offering HVAC services and custom ductwork for residential and commercial projects. One customer had a new A/C unit and furnace installed, and said Denis replaced as much of the old fiberglass-lined duct work as possible while keeping the pricing fair. A homeowner had Dennis switch an oil furnace to propane and upgrade the duct work. Dennis installed mini split systems throughout one customer’s house, so each person can now set their own temperature. A customer who had central air installed wrote that he also replaced and insulated duct work, and was on time and responsive. AirPro added A/C to one customer’s existing hot air furnace and replaced the old ductwork for better air flow. One customer had a thermostat replaced after it stopped working. One customer said the company did the HVAC system for their retail shop at a price lower than other quotes. On Google, it holds 5 stars from 22 ratings. It holds an active Connecticut D1 heating and cooling licence, HTG.0414293-D1, under Dennis A Malahan. **Strengths:** - Duct work replacement — a customer said fiberglass-lined ducts were replaced - Mini split installs — systems installed throughout one customer's house - Oil-to-propane conversion — a furnace switched to propane with upgraded ducts ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - Replaced fiberglass-lined duct work during a new A/C and furnace install _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2poSVJXaFRjWEp1UVVaWFZqUm5NVEJ6ZEZCcWNVRRAB!2m1!1s0x0:0x1811aee95732c146!3m1!1s2@1:CAIQACodChtycF9oOjhIRWhTcXJuQUZXVjRnMTBzdFBqcUE%7C%7C?hl=en-US) — “5★ Exceptional work and service!!!
