"O'Brien's heating and air is a very honest and dependable company. Edwin O'Brien came to our house during one of the hottest Friday afternoons during the Summer in 2014 when our downstairs air conditioner was not working. We were aware that due to the age and past issues that replacement was probably going to be our only option. Edwin gave us the price to replace the unit and was back first thing Monday morning and replaced our unit for a very reasonable price.

We were so pleased with O'Brien's heating and air, that we had them replace our upstairs unit the following summer and have recommended them to family and friends. These people conduct their business with honesty and dependability that is sometimes hard to find these days. Very highly recommended." — Sharon T.
