“Our A/C went out over the weekend and I called Leith at 8:55am this morning and Bryan was out here by 9:30am. After having Bryan come out I would never go with anyone else. Super nice guy and felt he was VERY honest not looking to nickel and dime ya and he explained everything he was doing in a way that it made sense to me and I appreciated that. I understand why they have the reviews they do. If your in need of any heating and cooling issues do not call anyone else you will not be disappointed with Leith. Thank you again Brian for being so wonderful I will be recommending you to everyone!”

“I highly recommend Leith Heating and Cooling. Rocco our technician, was on time, professional and fixed my problem in no time. He was very helpful in explaining how my furnace worked and how I could increase its efficiency by checking my vents and returns. The service call was very reasonably priced. I will be calling them in the spring to check and clean my air conditioning.”
– Lottie R.
“Brian and Rocco, Thank you both so much with not only fitting us in today, but also pointing out all of the potential issues with some of our previous work. We appreciated you answering our technical questions and the wonderful experience this install and the furnace repair last year has been. Going forward you will be our go to HVAC team, and that gives me a certain peace of mind!”

“Not fully satisfied with my old service so I decided to give Leith a try. Have lived in the area all my life and knew they have been around for some time. Glad I made the switch. I was kept informed of everything that was being done, technician was professional and friendly. Service was all I could have hoped for. They now have a new and satisfied customer for life. Brian and Rocco are the best!”
– Richard E.
“I cannot say enough good things about Leith Heating & Cooling. After trying to figure out an HVAC issue for two years, Leith came to our house and spent an hour investigating the problem. He finally figured out a solution that saved us thousands of dollars. He is smart, professional, and creative. This is a knowledgeable and honest company. Very grateful to Leith for their amazing service!”

“Excellent. Leith Heating and Cooling was very professional and prompt. Brian really knows how to run a professionally personalized business. I would definitely use again and would highly recommend them to others. They are a great example of a top quality, local business.”
– Tom V.
“From my initial call to Brian I knew that he was genuinely concerned about helping with my mom’s furnace since the temperature was dropping quickly and I was having difficulty with diagnosing the problem myself. He sent his technician over and he carefully diagnosed the problem and found a defect in the control board that I had installed a year earlier. These guys are very helpful and they treat their customers like family.”
