"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"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."
