Harbison Plumbing, Heating and Air Conditioning is a Houlton heating and cooling shop that describes its work as HVAC design and installation, covering warm air, hot water hydronic systems, radiant floor heat, air conditioning and open- and closed-loop geothermal. The company says it has been in business for 54 years. Its Maine hvac licence, number MS30002804, is held by DAVID A. HARBISON JR and is active on the state registry. A local news site, thecounty.me, has described a collaboration between the company and the Region Two Career and Technical Education Center in Houlton on a new mechanical services course for area high school students. A 2023 customer with an emergency leak at home said the employees were patient and skilled, explained the job and the options, and made the household part of the decision. A 2022 customer wrote that, after a call about water issues at camp, the problem was fixed the same day. A 2023 customer wrote, "Apparently you need the right name to get their services." A 2021 reviewer who works for a construction contractor said the woman who answered the phone was rude and hung up on a question about whether a product was carried.
“Thanks to a collaborative effort between the Region Two Career and Technical Education Center in Houlton and Harbison Plumbing, Heating and Air Conditioning, a new mechanical services course will be offered to area high school students.”
We had an emergency leak in our home. The employees were professional, friendly, patient and skilled. Excellent explanation of the job to be performed and options. We were made a part of the decision making. We would use Harbison again without hesitation.
Apparently you need the right name to get their services. Thanks for nothing
Had some water issues at camp...called...showed up and fixed the problem...same day...Yes...I can shower...
I work for a Major Construction Contractor and was referred to Harbison through another business. When I called to ask a simple question about if they carried a certain product the lady that answered the phone came off as quite rude. After I asked about this product she quickly said "no we do not, ok bye" and hung up before I could even get a word in. Sorry to the Owners of that company but that was enough to ensure I wont be calling back and will do business elsewhere.
