“Jeff is the best! He truly is so well versed in his craft and answered all of my questions. He recommended upgrades based on our needs and even pointed out issues with our dryer vent we hadn’t noticed before.”

“We had a great experience with this company. Our central air unit went out and needed to be replaced a few days ago. Spencer came out to do the inspection and got us in as soon as he could. He stayed in contact during the entire process. He and Chris are very knowledgeable and efficient. I'd definitely recommend this company to all of my neighbors and friends.”

“Ryan was on time and we throughly discussed what he would be doing during his inspection and the initial cost. He presented a range of other possible costs for repairs following his inspection and explained he would discuss this with me before proceeding with any other work. He was very detail oriented and knowledgable. I was impressed enough to enroll in their maintenance program.”

“Pass went above and beyond while installing two new HVAC systems in our home. Prior to this installation, the A/C only worked in part of our house and all we had was a gas fireplace in our living room. Now we have heating and air throughout our entire house. Our situation was a little bit different than most installations as we were fortunate enough to have all of this paid for by Operation Homefront. Pass took on this project for us in the middle of an already busy schedule. We were originally approved for one A/C unit replacement but when Spencer came out and did a complete thorough walkthrough, he was able to get us approved for two new heating and A/C units instead of just replacing the one ancient system that didn't work. Spencer is the epitome of Customer Service. If you look up Customer Service in the dictionary, you'll see a picture of one heck of a dude, my friend, Spencer Pass!!! None of this would have been possible without his efforts! The Pass crew, led mainly by Chris Roland, did an outstanding job. They ran into some troubles figuring out the old systems and with the new install but knocked it out of the park in the end! Thank you to everyone at Pass One Hour!”
