We had an idea but ended up discussing at length with the team about wall mounted mini splits, ceiling cassettes, concealed duct systems, and traditional ducted air handlers. They were knowledgeable and experienced with them all and encouraged us to ask questions and work together to find the system right for us. We felt in the driver's seat the entire time and went in certain that what we were installing was going to be perfect. The work was done professionally, with both their experience and attention-to-detail evident in the quality of the built-on-site plenum, neat and thorough taping, attic installed catwalk with work lights, metal line set cover, neatly positioned electrical disconnect and whip, etc. It was clear they'd done this many, many times before. Communication with both their office and the team on site was extremely efficient with everyone on the same page. Have a question about what they're doing? Ask, and they'll show you what they're working on and how they're doing it. They also left the place cleaner than they found it and treated it like it was their own. Truly an exceptional experience and job well done.

They could not fix the issue, but were able to tell me that I needed an electrician to repair a breaker. This advice led me to a quick solution and the air-conditioning is back on! Thank you so much for the quick service and for your good advice. It was definitely worth the $165 diagnostic fee.

He carefully checked my existing furnace and walked me through different options in a very professional and detailed way. In the end, we went with the option he recommended, and the entire process was totally transparent from start to finish. The installation crew arrived on time and kept me informed of their progress without excessive back-and-forth messages. Both Nahira and Rolando handled the removal of the old unit and the installation of the new one smoothly. After the job was done, they clearly explained how to use and maintain the new system.

Barsin the technician arrived and I appreciated how I received a text 15 min before letting me know he was on his way. It ended up being a simple fix of the capacitor needing to be replaced. No upsell, great customer service, punctual, and friendly demeanor. He also provided a receipt directly in a few seconds before he left. I've worked with other contractors where I needed to track them down for a receipt after I paid but he was quick and prompt! He also provided one year warranty guarantee on his work! Highly recommend! Don't call around. This is your guy to provide quick and trustworthy high quality service! Thank you!!!
