Verified record
Randolph Air Services is a Randolph HVAC contractor handling air-conditioning installation, heating-system work, and duct and vent cleaning. Google shows 3.7 stars from 18 ratings, with four recent written reviews from April through September 2026. The recent accounts emphasize careful explanations and competent work. One September homeowner said the crew explained how a vented ceiling could improve energy efficiency and patiently answered questions. An August reviewer found the AC installation affordable compared with another quote and said the technician explained how to use the new system. Another August customer said duct and vent cleaning took less than two hours and described the price as reasonable. There are two practical caveats to clarify. The AC installation took most of an afternoon and might have been faster if a spare part had been available. The duct-cleaning customer also felt the workspace could have been cleaned up better before departure. This looks like a good fit for homeowners seeking HVAC installation, heating service, or duct and vent work in Randolph. Confirm the parts and timing for an installation, and ask what cleanup is included before the crew starts.

The install took up most of the afternoon but that seemed realistic given the intricacy of connecting the vents with our existing arrangement. They were very thorough in explaining how the vented ceiling will improve our energy efficiency and were very patient in answering all of my questions.
Their pricing was more affordable than another quote I obtained. The installation of my AC unit took most of the afternoon but might have been quicker if they had a spare part on hand. I like that the guy was competent and showed me how to make the new system work for me.
Price was reasonable, guy came on time and did a great job cleaning the ducts and vents in less than 2 hours. They did a pretty good job overall but I observed they could have cleaned up the workspace a little better before they left.
Efficient and thorough, they ensured my heating system runs smoothly all winter.
