"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."

"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."

"I needed a bathtub installed in northern WV. However, the company suggested by Angie's list is located in northern Virginia.. hours away from my rental home. I entered the correct zip code, so I am not sure how this happened."
