"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!"

"Great! I have used Furr Plumbing many times so I was not surprised that they quickly located and fixed the problem however I was surprised when I received a NO CHARGE INVOICE! Thank you Furr Plumbing!"

"We purchased a house and adding a whole house water filter was on our list. Our local Orbit dealer performed a free water test and confirmed a that a lot of the junk we had read was in our city water was in fact there. Our previous house also had hard water and we saw firsthand what it did to our pipes and hot water tank. Plus we were tired of a filtered water pitcher taking up space in our refrigerator. Our sales person went over all of the features of the Puronics 7000 system and outlined the maintenance which simple and easy to understand. Installation took place about two weeks later and the guys were done in a day. About a year out and we're still very happy with the improved water quality and the system itself works great."

"When I bought my combo tankless boiler/hot water heater, the original installers messed up installation, then couldn't figure out how to fix it. Thank god I found Rod. He fixed their mess, installed a sediment filter that's been super effective, and recently helped fix a venting issue caused during a remodel. He knows his stuff inside out, is fast and efficient, and a real pleasure to work with. Would absolutely recommend him for anyone with on-demand water systems."

"I found TriState Home Services on Angies list and contacted them. Since it wasn't an emergency I scheduled them to come out the following day. The Plumber (Chris) did a great job assessing the problem with the leaky faucet and indicated that given the age of the faucet (41 years), he could attempt to repair it but wouldn't guaranty how it would last and recommended that I replace it. I agreed with his advice especially considering the price comparison of repair vs. replace - the price was reasonable. The quality of the work top notch, on time, and as promised. I would recommend TriState Home Services and will use them in the future."

"Our plumbing system was 33 years old. Arts Plumbing completely replaced the entire water system, plumbing, water heater, water tank, some bathroom fixtures, and installed a water filtration system. We had outside hose lines installed. The crew was experienced, professional, efficient and friendly. Everything was organized, labeled well and they went over the system with us. They offered a few suggestions that really helped the efficiency of the system. It was a pleasure having them do the work, great people! We were pleased with the price and we will continue to use them for all our plumbing needs."

"My well pump pressure tank needed service and I called Friday and Barbara was very professional and eager to help. She took the time to understand the issue and even reviewed the pictures. Barbara is very passionate about her job. She was able to schedule for Saturday. Dave came out. He called to let me know that he was on his way and let me know when he will arrive. He was very punctual, professional, friendly, and down to business. Totally impressed with the way he solved the problem and made sure that answered all of my questions. This company is very ethical and I would recommend them to anyone."

"

I called him in response to a leak coming from the ceiling in my living room -  he responded very quickly. Advised I turn off the water -was not sure which was the main water handle. I took a pic and sent it to him and he advised which one it was. Told me he wasn't sure if he could get by today. But then called me a bit later to advise he would be by that day. He was there for a bit trying to figure exactly where the leak was coming from. Cut a square area to access the pipe then replaced the section where the leak was.

"Technically the service went very good. Although they were being resistant about getting a permit which is required through my county, they did do it but later sent me a bill through the mail. This also included the price of a drip pan which I thought went hand in hand with the water heater. I was not aware I would have to pay these additional fees."

"They are extremely excellent. They rate plan is worth the monthly fee. And no additional charge other then plumbing and electrical. If they can not replace or repair it. They will come up with no charge. One time visit fee of 50 to repair sink or etc. Highly recommend them."
