They took the time to answer my questions and made sure I understood the process. The installation itself went smoothly, and the quality of their work was excellent.

I called 6 contractors to get some bids and the majority had a sales team that gave me the estimates, none are actual installers. Ian/Jason stands out because they actually came to my house, gave the estimate, and did the install themselves. No high pressure sales team and no technicians. Ian was very thorough on finding the right solutions for what I need, a rare quality nowadays for an honest contractor. On the day of the install, they came on time, completed the install, and cleaned up everything. I will be using Ian/Jason for all my HVAC needs and will be recommending them to friends and family.

We had our AC stop cooling in the middle of a hot day, and with two young kids and a dog at home,…read morewe were pretty stressed. Keon Garcia came out and did an outstanding job. What I appreciated most was that he didn't just start replacing parts. He thoroughly diagnosed the system, explained what he was testing, and walked me through the results. He showed me that the capacitor was testing low, the contactor was worn and pitted, and even performed a megger test on the compressor to verify it was still healthy. After the repairs, he confirmed everything was working properly by showing me the compressor amperage had dropped back to normal and that the system had an 18-degree temperature split. Keon was patient with all of my questions and never made me feel rushed. He explained the pros and cons of the recommended repairs, including the hard-start kit, so I could make an informed decision instead of feeling pressured. I really appreciated his transparency and professionalism. By the time he was done, our AC was cooling properly again, and he even worked with us on the final price. If you're looking for an HVAC technician who is knowledgeable, honest, thorough, and takes the time to educate his customers, I highly recommend Keon Garcia. Thanks again for getting our family cool again!

Well, after the warm weather last week we realized we weren't going to survive the summer with no AC. We called around a few different companies and ended up hiring Hammer's Heating and Air Conditioning to install an AC unit and hook it up to our existing furnace and central ducting. The owner Mike Hammer quoted us a very reasonable price, then came out today and did the entire job himself in a matter of hours, including installing a new smart thermostat and testing the whole system to make sure everything works. We now have a super efficient, slim Trane unit and are prepared for whatever weather gets thrown at us!
