Outstanding Work and True Expertise – Highly Recommend Leo’s Heating and Cooling Let me begin by saying Dmitry did an exceptional job installing a heat pump with a dual-fuel setup in my home. From the very first meeting, he impressed me by showing up in person and providing a clear, itemized quote—something that’s surprisingly rare in this field. This wasn’t a simple project. My house, built in the 1980s, brought several unexpected challenges. Dmitry not only anticipated potential issues but also handled each one with confidence and expertise. His depth of knowledge and professionalism really stood out throughout the process. Initially, the equipment didn’t work right out of the box—but this is where Dmitry truly shined. He was extremely responsive after the installation, going above and beyond to troubleshoot the issue. He even worked directly with Mitsubishi support to make sure everything functioned perfectly. While that level of service is impressive on its own, what truly sets Dmitry apart is what he achieved with my smart thermostat. I was repeatedly told by others that I’d need to replace it and use Mitsubishi’s own model, but Dmitry found a way to get my existing thermostat working—without losing the variable-speed functionality of the system. That level of care and problem-solving is rare. As I write this, I’m a very satisfied customer. The system is running flawlessly, and the quality of work speaks volumes. Honestly, I’m surprised Leo’s Heating and Cooling doesn’t yet have a Google listing—professionals like this are a hidden gem, and I never expected to find such top-tier talent through Thumbtack. If you're looking for HVAC work done right the first time by someone who cares about the details and stands behind their work, I wholeheartedly recommend Dmitry and Leo’s Heating and Cooling.

Thank you for recognizing the dedication—it’s customers like you that remind me why I love what I do. If you ever need anything down the road, I’m just a call away.

Alex and his team replaced my old furnace and did an outstanding job. The installation was clean and organized, and they took the time to explain how everything works. The new system runs great and the house heats up faster than ever. Highly recommend

I initially contacted Leo's for a second opinion re repair vs replace the furnace in our two story home. Gunnar came out right away and fully evaluated our current system, discussed options and provided a very thorough and clear estimate for each option. The follow up on my subsequent questions was fast and top notch. I'm still in the process of working with Leo's, but my initial interactions have been very positive. I get the sense they are knowledgeable and fair, more focused on the needs of our home and budget, and not on an upsale.

We had 4 different companies quoted for the service. Leo’s cooling & heating came with the highest quality quote. Dmitriy is very knowledgeable about the product, and he runs professional software to show us about the project that we want, instead of visual guessing the BTU of each mini split. We had lots of questions and he was very patient and professional in answering them. Alex and Mark were hard workers, they are great at their jobs. They helped us remove furnace, ducts, and installed 4 zone mini splits. Excellent service, we highly recommend them to everyone.

Details: Remove existing ducts and vents • 11 - 20 vents • Heating and cooling • Rigid sheet metal • I'd like to discuss with the professional • Two-story building • House

Did beautiful workmanship with adding 2 mini splits up and replaced the one down plus a new outside unit that they relocated and came back when I had a few questions. Big job done in a day!
