They came out to give me an estimate on a full HVAC system install, including new ductwork and floor vent cut-ins. Their pricing seemed more than fair, especially compared to a few other local competitors. My representative was Oliver Woelfling. He was very kind and honest with me while going over options for my new system. Oliver took his time when explaining to me the process and answering any questions I threw his way, which I greatly appreciated. He was also extremely proud of the quality of work his company provides; as he should be, the pictures he showed me of their work looked phenomenal. I was very impressed with his customer service and appreciated his knowledge of the industry. If you are in the market for HVAC services, I would highly recommend Oliver and his team. He certainly made it seem like this company genuinely cares about their customers, which is what this world needs more of nowadays.Response from the ownerThank you, Jesse!

From initial on-site consultation to the finishing touches and clean-up, the entire team was on top of everything and made the tear-out and new install a breeze. The quote was fair, and the suggestions were very well explained up front including pricing, absolutely no pressure to buy or upgrade, was all up to me - fantastic! The crew was on time, very polite, knowledgeable, knew exactly what they were doing and were very quiet and respectful in regards to the home and property. When finished, I was shown how to operate the new thermostats, the ins-and-outs of the new condensers, air-handlers, upgraded filter systems, UV air-scrubbers, and what everything is and why it is there!!

Judith schnokeJudith schnoke ★★★★★ This summer we were able to enjoy our sun porch and I expect it will be comfortable this winter due to your installation of a mini split system. It is far more economical than a room air conditioner or the electric heating we previously used. Thank you to Oliver and his friendly no pressure introduction to your company. He found what he believed would work best. Jeff, Steve and Terry work together professionally and efficiently. We actually enjoyed having them in our home. The only evidence that they had been here was the system. Thank you Precision. Looking forward to our next step in home improvement.Response from the ownerThank you, Judith, for sharing your positive experience with our mini split system installation. We're so glad to hear that it has made your sun porch more comfortable and economical. Oliver, Jeff, Steve, and Terry will be delighted to know that you enjoyed their professional and efficient service.

Patrick HaleyPatrick Haley ★★★★★ From the meeting and price quote with Oliver, to the install with Jeff and his team, Precision was flawless! They were very professional, and answered all my questions thoroughly! Our install was complex, so it took a day and a half.

Your satisfaction is our top priority and we look forward to serving you again in the future. toronka simmstoronka simms ★★★★★ Well let me begin by saying that there's always a company out there that's willing to cheat honest people out of their money but this is not one of those companies. Now my story. I purchased my home last year. This is my second home I lost my first one in a divorce. My air conditioner stopped cooling and my girlfriend called a company that rhymes with Roman🤣😳Well they came and quoted us 800.00. Told us the motor was bad. So we called Precision and they came out and inspected the unit and determined that it was dirt from grass clippings. They cleaned it out and had it up and running in no time. My bill was 129.00. So the question I have is either the other companies tech is incompetent or you really tried to screw over an honest homeowner for a couple hundred extra dollars. Either way Precision was a godsend for us🙏 Thank you for being honest and not taking advantage of a helpless consumer. We will be life long customers🙂 Salute👏I would give them 10 stars if I could!Response from the ownerThank you for sharing your experience, Toronka! We are grateful for your kind words and are glad we could help you with your air conditioner issue. We always strive to provide honest and reliable service to our customers. Your support means the world to us, and we look forward to serving you for years to come!
