Absolutely garbage. I have been charged $440 for a $15 part replacement. Ridiculous. This was the last time I ever called them for a repair. I suggest you look elsewhere too. Money does not grow on trees. Not recommended to no one !!!.

I think there are 2 R & D companies. I am referring to Lewistown, MT. We been having issues with our heater for many years. Dan came out and ultimately we decided on a new heater. Yes, it was expensive but after checking around the price was very fair. Installed in a timely manner, very responsive to my calls, invoice was as quoted, all work was professional and cleaned up after themselves. If there was 6 stars they would have it!

I had these guys install ac in my new office and all summer long its 85 in my office. they have been out like 5 times and still no solution. they recently told me that now it's because my windows are too big. but of course, they did nothing wrong. terrible company.

The humidifier on our furnace was leaking, so I called R&D. Daniel looked at the humidifier filter and said it needed to be replaced, so he replaced it and said that took care of the humidifier leak. He said the water heater was leaking, and he said he could help me replace it. He replaced the water heater under the warranty (it was less than two years old), and he said that would take care of the leak. The leak continued so I called somebody else. He actually listened to me and looked at the water line on the humidifier, and he found the leak in about 30 seconds. I told Daniel right up front that the humidifier was leaking, but he knew better. I won't call them again.

It requires some funding to deliver and i'm dazzled along with your out of the ordinary paintings. You are so savvy.

Professional, experienced, superior customer service, competitive pricing, trustworthy, knowledgeable, prompt, and courteous. R & D has the right business model for selling their products and services. We had purchased our old HVAC Unit from them over 23 years ago (a Bryant Unit, replaced with another Bryant Unit). From our salesman to the customer service representative to the installation, each team member at R & D was professional and courteous. We couldn’t be happier with our HVAC Unit (again).

We found out that we needed a new HVAC system right before Christmas. Our salesperson, Sarah, made sure we had the best crew to do the installation. They were excellent. Competent, experienced, polite, and just wonderful! I would highly recommend this company .
