"I had to replace a water heater quickly. Gave me a competitive quote with a water heater with desirable specs within a day and scheduled me the day after. Technician was knowledgeable and efficiently performed the work. Water heater performs just fine. Cleaned up workspace and took a few mins to walk through water heater and maintenance after."

"Marin the tech was great he was friendly and took his time to explain what happen with my water heater and how I could prevent the problem from happening again. I would differently ask for him again to service my water heater. Thank you Marin!!!"

"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!"

"Service was professional and experienced. They discussed with me the work that was involved before they begin the work, and whether there was any other options I should consider. The work was completed quickly, and the water pressure was improved immediately. I wish I had known the need for the repair long ago, we had been suffering from poor water pressure for some years."
