"I have an annual contract with R.W. Harrell's Pump Service to clean and service the heating and A/C systems at my home. Their employees and always prompt, courteous and professional and ALWAYS do an excellent job with cleaning up before they leave. Their prices are reasonable and I like dealing with locally owned companies as opposed to the nationally owned companies. I would highly recommend R.W. Harrell to all of my friends and relatives for their HVAC needs.

"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."

"I thought we would have to wait awhile and suffer through many 80-90 degree days, but they were able to come out right away! We called on a Saturday, they came out the following Monday to discuss paperwork/financing, and they did the job the next day on Tuesday. In addition to the HVAC system, we also had them install an air scrubber. Within 6 hours they were able to replace the outside unit, the AC, and the furnace, and install the air scrubber."

"They do a great job. Had a furnace installation and ongoing maintenance over the years. We have never had a problem. Very professional and qualified."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

"when I asked for an estimate on my ceiling fan installation, Murphy responded quickly with a time estimate, and suggested a couple of deals they had available with Angie's list. I took them up on the deal that seemed the best fit for my project, and made an appointment for the work online, so easy! The techs were on time, polite and professional. excellent work on the install, including electrical boxes and remote controls."

"We just finished put bathroom remodel and used Larry and sons at three different times during the project. Tyler did the initial plumbing, replacing our old lines and fixing some leaks. Next up was Andrew and he installed the bath light fixture, ran new lines and installed an exhaust fan and new gfi outlets. We finally got someone to move our vanity upstairs so we had Tim come out to install it and a new toilet to complete our remodel. All three were excellent and professional. Would definitely recommend Larry and Sons!"
