"Turned on the AC this morning to find out was blowing hot air, called up a few different companies who wanted minimum 100 bucks to come out blah blah blah, called up Markool and got connected with a technician. The technician helped me troubleshoot the issue, and have me a quick fix that will last until they make it out tomorrow to do the permanent fix. I'll be using them for all my AC needs in the future!"

"The contractor did a quick but thorough job repairing each electrical outlet and provided advice on how to maintain them properly. The ring doorbell installation was quick and neat. The contractor wore a face mask at all times and we had a completely contact-less visit (including the bill payment - we were able to "sign" via our own devices). This company was a pleasure to work with."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"It was a great experience. They exceeded my expectations. A team of detail oriented professionals made my dreams come true. They treated my house and belongings as if it was their own. I could have not found a better group to handle the job. I’m a very detail oriented person but these guys left me speechless."
