"Speer Air just completed a complete overhaul of my existing HVAC including an upgrade of part of our system. The entire experience from initial sales visit to completion was great. Throughout the installation, the team was friendly, always available to answer a question, clean and respectful of my 3 young children (making sure nothing was left behind or any debris that could hurt them). System is operational and very satisfied. Highly recommend them."

"Dave (Dawson Mechanical) is awesome. He is the only plumbing company I use. His knowledge is on another level and he runs a great company. It is easy to get an appointment and he responds right away. You can feel confident, if you have an emergency or non-emergency situation you that can get touch with him. In the past he installed a new boiler, furnace and converted us over to gas from oil heat. The work he and the guys did on the furnace/boiler is so good that other contractors comment on it. It really is a work of art - very neat. Most recently, he helped fix a bad plumbing job a contractor did during a bathroom model. The bottom of the toilet was flooding and the shower made a gurgling noise every time the toilet was flushed - it was an annoying odd problem. John came over during the covid pandemic, analyzed the situation and came up with a solution. He wore gloves, a mask and maintained space between us. I am very impressed with his expertise and the level of detail and attention he works with. However, I shouldn’t have been surprised based on how great of a company Dawson Mechanical is. He hires quality technicians. Lesson learned - dont let the contractor do plumbing work. I will definitely use Dawson Mechanical again."

"From the initial proposal and questions with Kevin to the installation with Mike and Milt, the professionalism and knowledge sharing was remarkable. To have the owner, Kevin, involved was a key influence in decision, as was our neighbors high positive regard for Ryan & Co. The installation was efficient. Mike and Milt were so organized and kept things neat and clean. They paid attention to detail and fixed the ancillary to the main system where needed. High quality all around. The system is in and can’t wait to see how it works, especially through the tricky up and down temps of the fall season. Farewell to the 35 yr old system."

"Pipe Works is a team of real pros, from beginning to end. First, you have Tricia (sales) and John (system design specialist) helping me figure out the right system up front. Even offered financing if needed. Then Ryan (Install Manager) stops by the day before the install to checkout site and make sure he's got everything covered. Then Shakil and Odin (installers) show up at 9am prompt for a full AC replacement installation (Condenser, Coil, Furnace). Shakil and Odin were true professionals (thorough, experienced, personable and efficient). They did a great job. Installation with no issues. They even cover the floors with protection and were mindful of the walls. Phil (electrician) checked out the electrical work. Updated the circuit breakers and ran the wiring that was needed. Also a professional with patience to explain things. And then Ryan (install manager) rounds back at the end of the day to ensure that all is well. Great job Pipe Works Services!"
