I thought that everyone at O'Donnell was very professional, from the owner Jim to the installers. I am very pleased with my new HVAC system. The sound level alone from my twenty-one year old Heil system to this new one has been reduced tenfold. I can't wait to see the reduction in my utility bills this winter.

The only comment I have is that the O'Donnell Heating and Cooling team is very professional and fast. The new furnace and air conditioning units were in in record time. Our old air conditioning unit broke when we had the hottest days this year. I can't thank you enough.

I couldn't ask for better service than I received from O'Donnell Heating and Cooling. Jim, the owner showed up the next day after I initiated contact and provided a highly competitive quote. His crew showed up on a holiday weekend (Memorial Day) to complete the install within two days of accepting his quote. They were professional and courteous throughout the entire process.

First of all, even before I actually had my new furnace installed, Jim O'Donnell paid a courtesy visit to determine my heating needs. Jim was professional and was very honest in his assessment. I felt extremely confident in his appraisal. Also, the furnace was delivered two days later. The gentlemen installing my new furnace were timely and very cordial.

The team was 100% professional in all matters. The initial response to my problem was handled by the owner who presented all my options to suit my needs. It was determined I would need a new furnace which I knew was most likely the issue. The subsequent actions after from the date & time of installation were all very accommodating to me.

I thank my lucky stars I went with O'Donnell Heating and Cooling when my steam boiler died. Jim O'Donnell is thoroughly knowledgeable, his men, Tim, Nick and Jeff, were excellent at their jobs and so nice!

Quality company. I've been using them for about 5 years now. started when I NEEDED A/C during one of our nasty July heat waves. Installed my A/C within a few days. I was not expecting that. Didn't jack the price on me either.

We needed to replace 2 furnaces in our house. The salesman was very honest in his recommendations for the best option for us. He didn't just try to sell us the most expensive furnace. The technicians were punctual, polite and conscientious.
