Furnace Repair in South Portland, ME 04061

April 15, 2025

“Big shout out to Sean! He made an emergency call to a 100+ yr old house I was housesitting when the furnace stopped working — on a recent cold rainy Saturday no less. I knew I was in good hands the moment Sean arrived– his expertise, patience, and kindness was obvious. In my book, how people treat each other is just as important as the quality of their work. I’m grateful that Sean was upfront with the cost of the parts and time required to do the job so I could give the information to the homeowners in real time which was clutch to the situation. He also brought attention to things the homeowners should be aware of regarding their furnace and chimney which they appreciated. AND, he left his workspace spotless (no clean up for me, yes!). I went from being super worried to super warm thanks to excellent service. Thanks again all!”

Estimate for Baseboard Installation in South Portland, ME 04106

October 7, 2025

“I requested an estimate for relocating a small baseboard with forced air heat. One of the two technicians–Mark– entered my basement repeatedly shaking his head to indicate he wanted nothing to do with the job, then made up a bogus reason that they were unable to take it (they don’t “FABRICATE DUCTS”). When I pushed back, he insisted I would need to call someone who specializes in metal fabrication and HVAC. This was a simple job, he just didn’t want to be bothered and assumed I was an idiot because I’m a woman and would accept his ludicrous explanation.”

- Susie V.

Response from Gelinas HVAC Services

Thank you for sharing your feedback. I’m very sorry to hear about your experience and the impression that was left during the visit. That is certainly not the experience we want anyone to have with our company.

At Gelinas HVAC, we work hard to treat every customer with professionalism, respect, and clear communication. Hearing that you felt dismissed or disrespected is concerning to me, and I take feedback like this seriously.

There are occasions where certain duct modifications fall outside the scope of what our service department is equipped to fabricate in the field, but that should always be explained clearly and respectfully. From your description, it sounds like that conversation did not happen the way it should have.

I would appreciate the opportunity to learn more about what happened and address this directly. If you’re open to it, please feel free to contact me at the office so I can personally look into the situation.

Thank you again for bringing this to my attention.
