Several weeks ago, our 13 year old A.C. System started giving out and John Poyle made the initial service call that led to purchasing a new system through your company.

I wanted to express my thanks to Mr. Poyle's professional helpful way of dealing with our needs. He is an outstanding example of Frederick Air. He was always willing to go 'the extra mile' and delivered on everything he said he would do.

If it comes up with friends or family I would certainly steer them toward John Poyle and Frederick Air.
—Alan Lehrman from Frederick, MD
I just wanted to thank you for the great service you provided from my first call with Rebekah and then my second with Teresa until the end result with Matt. You have three great employees that made my experience great. They were all a pleasure to work with. Thank you.
—Jennifer Peyton from Walkersville, MD
I just wanted to thank you, Ray, and the crew for the great job of installing my new central air conditioning system. Everyone has treated me with respect and courtesy during the entire process. I had approached other A/C installers with two requirements:

1) A central system for my small house, and

2) No or minimal loss of my closet space.

You were the only installers who readily took on these challenges.

Thanks again for the excellent job performed by all- my cat and I are enjoying it!
—Cindy Sigler from Point of Rocks, MD
We have appreciated your good service under our service contract and your promptness when our heat pump had to be replaced. Special thanks to Glen for listening to our needs and clearly explaining our options. Ray and his staff did an excellent job installing and explaining the care of our new heat pump. As Ray was measuring the space in our attic, he noticed light coming in around two pipes in our roof where the flashing was loose. The spring rainy season had begun, and he kindly caulked around the pipes as a temporary measure against leaks until we could have a permanent job done.

The heat pump we chose heats and cools our home quickly and thoroughly with Puron refrigerant and has a variable speed air handler which helps keep the temperature even throughout our home. It is quiet. I have asthma, and we also selected a special filter that cleans the air better than most filters. We are satisfied customers who freely recommend Frederick Air's service and the Bryant heating and cooling system.
—Robert & Linda Scovner of Frederick, MD
I just wanted to send a quick thank you to Dale and Rich, for a job well done cleaning our ductwork. We have had a lot of contractors in our home lately and some of them forget that it is someone's home. I just wanted to say that Dale and Rich treated our house like a home; they cleaned up after themselves and were very professional. I would highly recommend Frederick Air. Glen, our sales person, was also wonderful and a pleasure to do business with. Thank you.
—Art & Tina Boykin from Middletown, MD
Just wanted to drop you a note letting you know how impressed I was with the quality of service and professionalism of both your salesman Glen Anderson and your service tech, George. Glen was thorough in both determining the best system for my home, and answering all my questions. George was extremely helpful in answering specific questions about my existing and proposed system, and made recommendations for keeping my existing system running in the meantime, all in an unhurried manner (and at no charge (thanks!)). And both were able to come out the same day I called. I received less expensive quotes for the same replacement system from other dealers, but I decided to go with Frederick Air because of your outstanding service. Keep up the good work!
—Michael Mumma from New Market, MD
We would like to take this time to commend your staff on their promptness, professionalism, work ethics, knowledge of product, and friendliness when they replaced our old air conditioner for a new Bryant system on September 20, 2007. We enjoyed working with them and would be happy to refer your company to our friends and family should the need arrive. We look forward to dealing with Frederick Air through the lifetime of our new unit. Thanks again for a job well done.
—Charlie and Carol Shawver from Frederick, MD
