What their customers say
Quotes from people at Markool Heating & Cooling's customers.
“I had Markool replace my 25 year old AC unit and 20 year old furnace. The Markool team had my old units out and my new units installed in under 8 hours. They did a fantastic job. They made me aware of the 10 year warranty Carrier offers on its product, registered the units through Carrier. These guys are outstanding.”
“This crew was fantastic! They were very helpful in replacing my ductless mini split unit from start to finish! Chris was on point getting the replacement unit ordered and communicated with me throughout the whole process. The install guys Colt and Hunter were prompt, courteous and very knowledgeable about their work! I even signed up for the annual maintenance program to keep my units in tip top shape.BIG THANKS to MarKool for helping this lady out! Well done👍”

“Luke was super friendly and helpful. He replaced our capacitor in 10 minutes and had our AC working in no time. I would highly recommend using this company and their employees.”
“First time using Markool, Luke came to check out our units and was great about answering any questions I had. I’m a newer homebuyer and he gave me a lot of really good advice. Booking was easy, he was on time, very friendly, and was able to identify an issue (and fix it) before it became a problem for the rest of my unit. Plus my dog liked him, so 10/10 will use Markool again”
