HVAC reviews in Bangor, Maine

If I could give these guys 500 stars I would. They showed up within 1.5 hours of calling on Father's Day, fixed the toilet issue and throughly cleaned the space they worked in. Very professional, helpful and prompt in services.

ABM is great. They're friendly, hard working, and professional. I've never had a bad experience with them. Great to work with.

ABM does fabulous work in creating safe and comfortable electrical, plumbing and HVAC environments in buildings throughout Maine. The techs are professional, polite, and efficient.

ABM has been very responsive for condo we have in downtown Bangor. Quoted work, replaced a defective thermostat which is small work but were easy to deal with and arrange.

Our family has been working with Mike and the team at ABM for years now. We highly recommend them and will continue to use them for all of our projects in the future because of their professionalism, responsiveness and their overall quality. They are second to none and the best sub we have ever worked with.

This company does very good work.

They do excellent work, will an extended review at a later date.

Can't find a website , why are you guys not getting one , a website would be a game changer

They have no online access that mean they dont have website and they dont pickup calls their services are slow genuine advice you must focus on building you website!!! thank you so much.

Call disconnects after 1 ring I tried several times

The only Heating Company that answers his phone and goes out of his way to help you when your in need of furnace work!

Everyone was booked until December. Had no water or heat for 3 weeks. I called on a Friday. Owner, Ronnie, called me at 830am the next day, Saturday am. Showed up at 10am the same day. Gave us a great deal since we helped with some of the stuff. Highly recommend.

My furnace was out for almost 20 hours. I had called a dozen companies looking for a weekend tech to come out. My family had already left and it was just me, here in the cold. Mr.Overlock was the only person to call me back in a timely manner and responded within an hour of my call. He billed me fairly and worked diligently to repair my furnace to get heat flowing for my family and I. Dont spend your money elsewhere, Ron is the man you want and need. I would gladly pay him again to do any kind of heating work. Unbelievably satisfied with his work and effort. Thank you, Ron. From my family and I.

Excellent. I was dealing with a leaky cast iron heater for weeks with another company, who after 3 visits, nearly $300, and a last minute appointment cancelation did not resolve my issue. I called Black Diamond and they came out and fixed my issue the SAME DAY and consulted on two separate issues. I'm thrilled.

They have no online access that mean they dont have website and they dont pickup calls their services are slow genuine advice you must focus on building you website!!! thank you so much.

Very disappointing. Called a Saturday morning with a not working furnace and was basically told because of my neglect he was unwilling to come out on a weekend. It was very rude and I'm happy to send my business elsewhere.

We can always count on Witham's to be there when we need him, and his honesty and fair prices keep him in our contacts list. Highly recommended!!

He cleaned my furnish and replaced the "elbow" to the Chimney. He was very polite, helpful with answering my questions. He was timely and reasonably priced. I would recommend him and will call him for my next furnace cleaning.

Great service, fit us in even with a busy schedule and really knows his stuff. After 2 days of backyarding it , Andy diagnosed and fixed it within 10 minutes. You can't put a price on that kind of service!

I called my oil delivery company to clean my furnace before finalizing the sale of my house. The technician came in and told me that I would have to replace my furnace because it was overheating around the exhaust vent to the chimney. It was going to cost $3,800 to replace the furnace. I called Andy for a 2nd opinion and he promptly came over, checked the furnace, and said it just needed a new gasket and a good cleaning. Andy came back the next week and completed the work and charged a very reasonable fee. Andy saved me nearly $4,000 for replacing a furnace that wasn't needed. I highly recommend Andy for your heating needs!

We have a 2 story house and I think it would be difficult to put heat pumps in. However, Andy and his team worked hard and barely took a break for lunch, They cleared the construction debris and took it away. We had them install 4 and they are worth every penny.! If you want quality, truth and a fair price definitely contact Witham Heating.
