"Juan responded quickly on a Sunday afternoon. He was very knowledgeable and fixed the broken part. Fortunately, Juan had the part in his truck and was able to get my furnace working again. The service was impeccable! However, the weekend rates are expensive the service cost me $699 for installation of a $70 part. The 2-hour service call was $500 ($249 per hour)."

"John was awesome. He was professional, friendly and very knowledgeable. I had previously had some repairs done to my central air system by another company. That result was not up to my expectations. John from Quiet Corners came out, accurately diagnosed my problem, and came out within a week to install a new condenser. We now have cool air in our house. They also work with American Home Shield, which covered most of the cost of the repairs. Great Experience!!! I highly recommend them.."

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"Vista installed new vinyl siding on our house and I couldn't be happier with the result. Our house looks brand new and I love the color. The communication was excellent! Every step of the project was very organized and I loved how Keith and Brian checked in every few days. The work crew was very repectful of our propery and the quality quality of work is amazing. Overall it was a refreshing, seamless experience. I would highly recommend them."

"Very well. I had an appointment for approximately 8 AM. They were a bit late, but had called to let me know, and it wasn't a problem for me. They spent well over an hour on the job. They took a ton of lint out of the vent pipes and the dryer itself. I'm pretty sure that whoever it was I had in last time did not open up the dryer to clean it. They also installed a "bird cage" around the vent opening on the side of the house to prevent critters from getting in. (I don't think I have had problems with birds getting in, but why take the chance?) They were very thorough. The job cost more than the initial estimate, but this was because my vent pipe was longer than I had realized. It was reasonable."

"We hired Charter Oak Environmental to clean our central a/c ducts so they would be ready for the summer season. We had renovation work done over the winter and we were concerened there would be a lot of dust, etc. in the system. We had never had a cleaning done before and didn't know what to expect. We have used COE before and were always pleased with their professionalism and quality of work. The workers arrived on time and their supervisor, Mike, (who is AMAZING, by the way) was there to check in with me and get things started. The work was done within one half a day and the crew left my home spotless, as always. When I had a few questions, they took the time to talk with me, fix some things and they even explained to me that a ledge in my great room had accumulated so much dust, that they went up there and vaccuumed it for me, even though it was not part of the job. This is typical for COE, they always go above and beyond. When I tried to turn the a/c on the next day, but couldn't figure out which switch needed to be turned back on, someone came right out and turned on my a/c for me so that my house was comforatbly cool when I arrived home. This is the best company we have ever hired to do work in our home and we give them our highest praise and recommendation. Mike Doherty is a wonderful person and he is always helpful and kind to his customers. Also, this company does great work and they are respectful and clean up after themselves. We have never been overcharged and we have never been disappointed by their work."
