"Vince told me outdoor spigot could be repaired and did not need to be replaced which saved me money. He also replaced a vanity faucet which I provided. He was quick, efficient and honest. The most important thing was he discovered a serious problem with the way my water heater was vented. The exhaust pipe had been cut wrong and glued together. It was ready to come apart and could have vented carbon monoxide into the basement. (We do have CO detectors but this is still scary) We had this water heater installed a couple of years ago by another well known local firm that I don't know if I can name here. It did fail inspection by Howard County 3 times after initial install. Failure was all related to the vent and probably should have never passed. Anyway, by pure luck it was discovered and fixed. Thank you Vince!!"

Customers say: Super punctual

"Fred is very personable and friendly. He returned my call right away, even though I placed it after hours. He replaced one old toilet with a new one he just happened to have in his truck, and it works great even though it's a low flow one. Prices are very reasonable. Fred is my plumber from now on."

"Joseph Plumbing and Drain replaced our aging (21 year old) Rheem water heater with an AO Smith Proline 50 gal model. Kap, the owner of the firm, came out to give us an on-site estimate and a detailed explanation of the work to be performed. He showed up at 9:00 am two days later to do exactly what he had promised. Of the six different proposals that we reviewed, Joseph Plumbing and Drain came out on top. They were neither the lowest nor the highest bid, but in our view, the best bid. We found Kap’s price reasonable, his knowledge comprehensive and his work thoroughly professional. We felt we got a quality water heater and expert installation at a fair price."

"Our furnace finally bit the dust after 25 years of faithful service. I had TriState do several small repairs and maintenance on it over the years, and they always did a good job. So, when the last service rep told me it was finally beyond repair, we consulted with Comfort Specialist, Darren, who isn't just a salesman, but previously installed and repaired HVAC systems. He took lots of measurements, inspected the old unit and the runs to the outside and upstairs. He took his time making calculations and offered us several options on a new system. TriState uses Daikin furnaces, which are rated in the top 5 furnaces for dependability and efficiency. The price, I thought, compared to my two other neighbors, who also recently purchased new systems, was even lower than I thought it going to be. In fact, my neighbors paid more (by thousands) and have a smaller square footage footprint than my house. We've had the unit now for over a month, and so far, it's great. It is a one-zone system, yet the upstairs will only vary by one or two degrees. This is much better than the old unit. We're hoping this small variance in temperature will also apply when the AC is on in the summer. The installers were very professional, arrived on time and completed the work in a timely manner. I would definitely use TriState again, and will rely on them whenever I need service."

"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!"

"Pohlman responded quickly when my water heater leaked and quickly replaced it at a competitive rate. I asked for multiple quotes and they were one of the first to respond. I appreciate the work, although I would have preferred to know which water heater was being installed before they put it in."

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."
