“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.”

“I still need to have him install a backsplash around the sink when I buy it, which is why there is a gap on the side of the sink. That will be covered. Highly recommend his work. He has a great team he works with who all have just as good of attention to detail as him.”

“When I asked if they could install the smart thermostat I purchased separately, they had no problems with. Job was done quickly and professionally. Saved us a lot money on the other 2 bids I got. I would use them again.”

“That changed the dynamics and the company then went beyond code requirements to install a new vent. Thank you Ethan for looking out for me and my household!”

“I had a mini split installed in my older home, I was unsure if it would be compatible. Jayme and his team assured me the installation would not be an issue. This company has competitive pricing and competent staff. I'm very pleased with my purchase and I highly recommend this company for any hvac needs.”

“Great job—Chris installed a new garbage disposal for us. He took great care coming in, did the job, and left our place super clean.”
