"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

We are a small family own business. Our services include Septic tank cleaning, repairs and installation and grease trap, cleaning, maintenance and small repairs.
"I got a call from R & E Chief Septic llc after contacting Angi’s List, they asked if I knew the location of the tank and I said yes but it was buried, the woman on the line said they would get the drawings from the county, that same day I got a call from Juan one of the employees and he said he was going to stop buy and mark the location, I was not home but when I got home I could see white flags in the yard. They also recommended installing an above ground cover for the next pump out. I got 2 more estimates and they were all higher and neither company offered to come out and mark the tank. We went with R & E Chief because of the great up front customer service. Need to give a shout out to Juan, Fredy and Paco they did an excellent job. And also the woman who answered the phone. So if you need septic work done, put this company at the top of your list. Ron Welch"

"Everything went very smoothly. Sam, the plumber, and is highly professional and knowledgeable. He replaced 3 faucets, 2 sink plugs, two valves, and two supply lines. Sam inspected the p traps, and he added adhesive where it was necessary. Sam also took a look at my two year old hot water heater, and he assessed my water supply to this unit. We discussed performing a complete drain, and check of the components of the heater at a later date. Sam also advised me that a toilet in the basement should be replaced with a more updated commode. We rarely use this toilet, but it's 35 years old. I felt comfortable speaking with Sam. I did not sense he was doing a sales pitch."
