The technician that performed our annual heating system check was excellent. He was very professional and thorough in explaining the services he performed and even helped to rectify a problem I was having with my humidifier.

Many years ago Frederick & Sons installed our top of the line heaters, air conditioners and humidifiers in our home and we have been very satisfied with their customer service ever since. The technicians are courteous, knowledgeable, prompt and most respectful not only of the client but the client's home. No matter what problem might arise with any of our systems, one call gets you an immediate and friendly response and quick service/repair. We recommend this business highly.

CJ quickly introduced himself as soon as I opened the door. Don't think techs in prior years did. Nice touch. Had a question about a reading listed on the service form. Nothing was wrong. Just a matter of never asking what numbers represented in the many years of having service. CJ politely & friendly answered & took me to the heater to show where info. was located on manufacturers plate. He represents your company well.

Aaron came to service our heater for it's annual maintenance. He said there were no issues, so everything was taken care of quickly. Aaron was on time, neat, and very pleasant to talk to.

The HVAC tech, Bobby, was very professional and personable. He did clean and efficient work on our gas furnace and was very knowledgeable to answer any questions we had.

My sister had recommended this company as they had replaced her house heater. I had them repair a break in a water line in the floor awhile back so when I woke up on Christmas Eve morning and had no heat, they were first in my mind. As it turns out, the were able to restore my heat and since the heater is now 43 years old, it's over due to be replaced. That's their next project for me. Don't hesitate to give them a call when you need service.
