"Scheduling was easy and efficient. Tech arrived on-time and quickly diagnosed and replaced the faulty part. Will be hiring them again."

"They did an excellent job replacing my sewer line. They were prompt, courteous and do great work. I would hire them again. I believe it was good value for the money and they stand behind their work and they were willing to come back and answer some questions. I know very few companies that operate this way."

"Of course the A/C quits on the afternoon of the 90+ degree day! Fan and compressor were not working, but indoor fan was, meaning either a capacitor or contractor issue in the outdoor unit. Called office 10 minutes before they were done for the day, but was able to confirm a repair appointment for first thing the next morning. Technician (Sean) was here at 8 am, and after a 2 minute discussion and check, confirmed that capacitor was the issue. Still under warranty from Bryant, so that was a plus, but I was surprised that there was a failure after only 3 years since last unit ( also a Bryant, nd installed by AC Engineers after house was built in 1997) never had a problem for the 17 years we had it until replaced with the higher efficiency unit. The interesting comment from the technician was that he would likely replace 5-6 more capacitors that day (!!!!!), not tied to any particular brand of unit, but more because all the manufacturers use the same capacitor from the same source, and "they literally don't build them like the used too". Rather illuminating - In addition to the capacitor fix, he did a full service check of the system. Excellent job, responsive and knowledgeable."

"I pulled up Angie's List and selected CSR (Complete Service Restoration). Within 30 minutes after contacting CSR, Ron Minando was at our door. Within another 45 minutes Ron's crew arrived. As Julius Caesar said upon landing in Britain, They came, They saw. They conquered. With CSR, They came. They saw. They conquered a smelly, moldy, and disgustingly wet basement. To ensure that water, dirt, and contaminants, were not tracked into our house, they put down a waterproof cloth matting on the main floor, the laundry room and the garage. Working in a quiet professional manner, the crew drained the basement, extracted water from the carpeting and padding, zipped it into watertight plastic bags and disposed of it in a dumpster. They did the same with the wet drywall and some water damaged contents. They moved so quietly and quickly that my wife and I were unaware they brought in very large air scrubbers and dehumidifiers. After removing all the contaminated debris, they sprayed the floor and walls with a plant-based (no toxic chemicals) anti-bacterial agent. By acting quickly, CSR was able to save my wife's hat room and its 300 plus hats Hooray! It took several days to remove mold and dry the basement, but when they finished we had a clean odor-free basement. The men were prompt, very courteous, professional, and knowledgeable about the dangers of a water/mold damaged basement. If needed, I would definitely hire CSR again."

"We were very impressed with Quality Air Control Heating & Cooling. The service techs arrived on time, explained the entire process, friendly and respectful of our home. This company was amazing, we will certainly use again!"

"It went great, it was a messy job because it involved removing the old, nasty insulation, but the guys did their best containing the mess. The attic is very difficult to work in due to the low ceiling and they did a great job, no cracks in the ceiling or anything. I also ended up with a "super deck" which is a platform with foam underneath giving me some more storage space that I desperately needed. I can see now that my neighbors house has icicles (which can signal an impending ice dam), and I have none. I gave a B for price because this is an expensive job, I don't believe you can get it for significantly cheaper, but the quality of the job, comfort, and properly functioning attic space are definitely worth it."
