We had the most difficult time with our home warranty company not handling their responsibility with this repair. Rural was so supportive, and active in advocating for us, and getting to us as soon as they possibly could. They were extremely professional and diligent. Would recommend them to anyone. Thanks Eric.

RHACS is always able to assist with my immediate request. From start of office calls to prompt scheduling and short wait times to efficiently and effectively resolve our issues. I would recommend RHACS as a top notch business.

Eric and his crew went above and beyond to make sure that my system was up and running, even after the winter managed to freeze the pipes and leave me without heat in -20 degree weather. Over a year and a half he dropped what he was doing to work through my 1918 house problems. His top priority was to get my family heat and at times worked after hours to make it happen. He has always been a pleasure to work with and no doubt at all that if I asked him for his shirt, he would give it to me without a hesitation. He’s earned my business for all future heating and cooling needs and I highly recommend his services. I’m willing to chat with anyone over the phone to let you know how much he helped me and chat on his overall commitment to service to his community.

From the first point of contact with Michelle, I explained that the service we required was an emergency. Michelle treated it with the utmost urgency. James was our technician who communicated clearly on timeline and expectations. Rural Heating and Cooling was fast, efficient, and reliable. (Also fairly priced) It was clear to me that the owner was available to provide all approvals needed to get our service done in less than 24 hours. THANK YOU so much for your help.

I had Eric, RHAC, install a new furnace in a home I’d purchased. Unlike many contractors, in these times, he actually answers the phone, tells you when he’ll be there to service your equipment and shows up on time, prepared to work. His costs are extremely competitive and his workmanship is second to none. I would highly recommend RHAC. THANKS Eric.

I highly recommend Rural Heating and Cooling. I have a home warranty and kept having issues with my furnace. I had other companies come out and they would temporarily fixed the issues I was having. I kept having the same issues. When Eric came out the first time, as the motor stopped working (he was able to get it spinning again but it was loud like it was going to blow), he recommended a new furnace. My warranty company approved the new furnace but there was some additional expenses for some HVAC that needed replaced. He worked with me on getting that paid and he ordered the new furnace. I had it replaced in about a week. Today, first snow on the ground, and I wake up with no heat. I called Eric at like 7AM in the morning and he promptly called me back. He walked me through possibly issues that I might be able to fix on my own but none of those worked. He arrived at my house in hours and he determined there was a defective part that was throwing an error code. He was able to get it working, but the manufacturer warrantied the part and we were good to go. He was so kind and gracious the entire time. Thank you for your service, we appreciate it.

Super nice and very knowledgeable. Highly recommend RHC


-JaneDoe

Great guys and great work. We had some trouble with our boiler and had some other folks come work on it first, prior to being refered to RHACS. $1300 later and mulitple visits, it still wasn't fixed. They refused to work on it any longer and suggested I replace the entire thing and quoted me around $10,000. I called RHACS after McCleary's referred me over to them, and they replaced a few parts and got our boiler running. I'll be using them to also take a look at my AC, and do some chimney sweeping. They've got my business from now on.


-Bill

Our oven went out and our home warranty company put Eric and his team in touch with us. Eric was was prompt and quickly diagnosed the problem. It took a while for our warranty company to approve the repair, but once they did Eric immediately contacted me and replaced the needed parts.


-David Trich

★★★★★

Our boiler failed recently during a dangerous cold snap. Eric and Chris with RHACS responded quickly and professionally. Eric kept us informed and updated through the entire ordeal and even came back twice to make sure there were no issue's with the newly installed boiler. Eric and Chris left us with a very high level of comfort and we will publicly support, and recommend RHACS for heating issues going forward. Thanks guy's, you're the best!
