"Tipping hat has talented employees that do safe, clean, and complete work! I highly recommend them! We are no longer cold in our house thanks to Mark J, and service pros Jeremy D and David B. Mark J. the supervisor on our furnace installation project was the first person we met from Tipping Hat. He is kind, understanding and respectful. He took time to thoroughly examine our complicated and difficult heating situation and was able to explain what needed to be done and why. All of our questions were promptly answered, he was always available for a phone call and put extra effort into creating a plan and setting up a team to get started on our project right away. Mark was considerate of our feelings, always reassuring us and promptly addressing all of our concerns. Jeremy D. Tipping Hat's Service Pro, provided extraordinary service during the installation of our new furnace! He is punctual, courteous, professional and knowledgeable. We were comfortable with him in our home, as he took great care installing our new thermostat and kindly showed us how to use it. Jeremy was very patient and took time to answer all of our questions. He went above and beyond to ensure that we received exactly what we needed AND he saw to it that the work was up to code and done properly! We are so appreciative of his compassionate understanding of our situation and his prompt completion of a large, heavy duty job that required hours of hard labor. Tipping Hat's Service Pro, David B. was able to complete work on the installation of our furnace in some really tight spaces. He had to deal with a tiny, dirt crawl space underneath the house and was able to re-attach ducts to the vents in our home. He was positive, pleasant and hard working. I feel confident referring others to Jeremy D, David B, and their Supervisor, Mark J."

"We have been using Plumbing Tree for all of our plumbing, air conditioning, & heating service since we found him 2 years ago. Kieth may not be the cheapest guy in town, but you get what you pay for. He knows what he's doing and makes sure it's actually fixed right. This time, I had him out to talk about a barhroom remodel I want to do, but ask him if he could replace a valve in my kitchen faucet "to make the trip worth his time". They didn't just see the faucet was leaking on top where I saw it but took time to check underneath and found leaking valves that were damaging the cupboard underneath and even a little into the flooring below. No question, the faucet needed replacement and new valves. I love my new faucet!"

"​Loos & Sons HVAC did a stellar job diagnosing the issue with our system; the technician was incredibly knowledgeable and quickly pinpointed the root cause. We especially appreciated that they took the time to clearly educate us on the problem and walk us through all the available solutions. This commitment to transparent service and customer empowerment makes them our new go-to company, and we highly recommend them."

"Every step, from the estimate with the super friendly Ryan, to the final walk-thru with the always professional Gemini, was absolutely top notch. They installed a new furnace, A/C, and tankless water heater and we are very happy with the work and final outcome. The whole crew was wonderful!"
