We recently had a tankless gas hot water system installed. We were very impressed with the service . Austin Noe was very responsive and patient with us in making a decision on what to go with. The Installers Jason and Kevin were very professional and knowledgeable . Arrived when they said they would and kept us informed during the entire installation. We would highly recommend Pioneer for your heating, AC and gas installations. We also signed up for their annual check ups for our heating and AC. Thank you Pioneer !

Pioneer installed new heat and air three weeks ago and we are very happy with new system and service we received from Pioneer. Austin gave us four options for system and explained the benefits of each. Installers (Jason,Kevin,Mike) were on time and worked a long day to complete install. Looking forward to many years of use from new system and happy to have reliable company to maintain it. Thank You

This company is top-notch! Our heating unit went out on a Sunday and someone came promptly to our house and fixed our unit. Brandon was wonderful, he showed us our problem and explained what happened and how much the repair would be. The repair was fair and reasonable. I highly recommend this company and will use them again without hesitation.

After going through close to a dozen HVAC companies in the Knox County area over a 12 year period, and finding greed and incompetence was the key driver of these companies, I tried Pioneer, and to my surprise and joy Pioneer delivers. They have competent and knowledgeable technicians. They arrive on time. They are considerate of my home, wearing blue booties, and give straight answers to questions. The office staff is a delight. They will work with you schedule for your needs, and do so pleasantly.

A truly professional experience at every stage, from customer service, to dispatch, to estimator, to installer. Everyone called when they said they would, and arrived at the scheduled times. The repair/install was completed flawlessly. This job was for my mother, who lives alone. She was very impressed with the professionalism of the uniformed estimator and installers who introduced themselves to her with a handshake. Without a reference from someone, I was reliant upon reviews when deciding on an HVAC contractor. There are many companies out there with a zillion high-star reviews, but I found Pioneer to excel after sorting on "most recent". Many of these other companies had their last great review a month--or months ago, while Pioneer has an ongoing track record of excellent RECENT reviews. I am fortunate to have made this call, as it was hands-down, the best contractor experience that we have ever had.
