  New installation of Daikin furnace and heat pump to replace 25 yr. old Trane system. Sales Rep Brady was extremely knowledgeable. He mapped every room in the house to determine load calculations and equipment recommendations. This was provided to us along with quotes for three system configurations. Installation was completed in two days by Logan and assistant Zack . As stated by others, Logan was very knowledgable and professional. I was very impressed with their attention to detail.

  Have used O&H for the last few years. Excellent personnel (that's their strength), very professional, polite. Very knowledgeable staff. Prompt, too.

  The response time on the return call for an immediate issue on my furnace was unbelievable and so professional they knew my system, helped me through it on the phone without a service call. They are great I will always look toward them for my AC and heating needs.

  O&H was the most professional and knowledgeable of all the estimates I got, and that held true throughout the installation process. My new Trane system holds at a rock steady 72 and I can barely hear it. Looking forward to many years of enjoying my HVAC investment!
