Heating/air conditioning project

Sig W.

In 2016 we bought an old (1840) house in Nantucket. The heat was circulating hot water with enormous old cast iron radiators which had some leakage. Air conditioning was in the form of window units. We decided that the heating/air conditioning should be upgraded. We contacted Guy (who by the way was a friend of a friend of mine on the Cape) to evaluate the situation and come up with a solution including a detailed recommendation. Guy came and after investigating the situation presented us with a plan including an estimate for the work to be done. We agreed to the plan and Guy’s associates put the plan into effect. The workmanship was outstanding in every aspect. The workers were knowledgeable and pleasant to deal with. As could be expected with an old house there were of course a few cliches which were addressed in a timely fashion. We are most pleased with the heating/air conditioning work done by Guy’s firm and would gladly recommend them to anyone needing the type of work we had done or any plumbing, heating or air conditioning project. We would be happy to be used as references.

We are so pleased with their services and their employees. We are converting from oil to gas, and it can be a process. They guided us , and did everything. Making it so easy for us. Lastly, their prices are fair and reasonable

Year round oversight.

Bill S.

We rely on Carl Riedell & Son for all of our heating, plumbing and air conditioning issues. As we spend most of the year in Dallas it is important that we have someone we trust completely to identify and take care of any issues we have. Carl Riedell & Son fit the bill perfectly.

"Excellent in Performance"

I have experienced "Over 20 years" of Quality service by Carl F. Riedell & Son. They are thorough and complete their plumbing tasks on time. Perhaps a bit high priced but worth every penny!

Big help

Beth B.

Dick Mohre helped us through the cumbersome process of installing central air into our Hyannis condo. Those efforts included not only getting the unit up and running, but guiding the final acceptance decision from the condo Board. Additionally, Reidell has helped address heating issues in a timely and professional manner when we have had problems. Dependable.

Thanks for your review, Beth - our team is experienced in working with third parties to a project like a condo board, and we're glad we could ease the process.

Rick Summersall and Dick Mohre came out to my house and went over options for us to heat and add ac to the house. We had no gas to the house and they explained what we would need to do. They explained about adding a furnace and central ac. Due to the fact our basement was finished we would have had to had furnace in the attic. We were not thrilled with that idea. We ended up haveing thhe Mitsubishi mini splits with heat pump installed. The workers did a great job. We had Rick come back to give us an estimate to bring the gas in the house and install a tankless hot water heater. Another great job completed. I would use these guys again if I need any work done.

Thanks Ann! Our team is glad to walk customers through our recommendations and the steps of each project. If you do need work on the house again, give us a call.

The work was done fast and the issue was explained. I’ve had no issues with the unit since the fix. Great service as expected.

Dependable, Professional, and Resonably Priced

When I need a plumbing or HVAC problem resolved, I do not even have to think about who I call, When I call Riedell, I know the phone will be answered by a person well trained in their job. No buttons, questions to answer, or transfers to make. And that reflects how the procedure will continue. Any job will be done correctly, Simple.

We have been so happy with everyone from Reidell Plumbing who came and worked on our house here in Cotuit. We made several plumbing changes and every job was well done in a timely manner. Also, the girls who work in the office are always very helpful.
