If you need someone reliable, trustworthy, and above all, ethical, stop searching and hire Maksym. That's truly all you need to know.But if you want more: Maksym came to my rescue at the last minute when my AC failed completely. Other companies left me reeling with sky-high quotes--some exceeding $20,000 to replace the entire unit without bothering to do a detailed check. Maksym arrived promptly, provided an exceptionally thorough diagnosis, and not only fixed the problem the very same day, but did so with a warmth and professionalism that's rare in this business.Beyond his skill, Maksym is simply a pleasure to work with. He operates with an integrity and honesty that is evident the moment you speak with him. He laid out exactly what repairs might be needed down the line, giving me peace of mind and confidence in future decisions. My AC unit is old and well past its prime, but Maksym managed to breathe new life into it, saving me thousands and buying me valuable time.It's rare for me to say this--I'm notoriously skeptical and picky when it comes to hiring help--but Maksym has earned my complete trust and loyalty. When the day finally comes to replace my unit, he will be the only person I call.Maksym and Maksbuilder, thank you for your incredible work. You turned what could have been an expensive nightmare into a smooth, fair, and surprisingly pleasant experience. You've gained a customer for life.

My A/C started blowing warm air so I started looking around for an honest HVAC company. Maksym responded promptly and even came out the next day to look at my unit. He accommodated my schedule and even worked quietly so as to not wake my kids. He gave me a reasonable quote and was able to fix the problem right away. More than that he fixed some things on my unit that might cause problems in the future. Really a great guy and a quality technician!

Slava installed a Lennox furnace at my Laguna Beach home, and I couldnt be more satisfied. He arrived on time, was very polite, and explained the entire process. The furnace is running beautifully, and my home is much warmer and more comfortable. The best part is how efficient the system is, which has already lowered my heating costs. Slava also helped me with rebates, which was a nice bonus!
Maksbuilder's reply
Thank you so much for your wonderful review, Jaiden! I'm delighted to hear that Slava provided timely and professional service, and that you're enjoying a warmer home with a more efficient Lennox furnace. It's great to know that the rebates were a helpful bonus as well!

I had Kevin replace my old AC unit with a Goodman system at my home in Lake Forest. Kevin was very professional, taking time to assess my home and explain the different options. The installation went smoothly, and the new system is working wonderfully. My home stays cool even during the peak summer heat. Kevin also helped me apply for rebates, which made the installation more affordable.

I decided to go with a Daikin heat pump for my Irvine home, and Slava was the technician who handled the installation. He was professional and explained how the heat pump works for both heating and cooling. The installation was smooth, and I can already feel the difference in both comfort and energy savings. Slava also helped me with rebates, which made the entire process more affordable. Im very happy with my new system!
