These folks are unbelievable! They installed a new gas furnace for me a few years ago. There were some performance issues because of the existing duct work in my home. After repeated adjustments to try to get it to work, they upgraded me to a more expensive model that would work for me at NO EXTRA COST! Who does that right! Can't say enough good things about this company top to bottom.

Tim R installed our hot water heater in 2017. Since then Tim has responded to our house several times to tune up and repair/maintain our aging HVAC systems. Tim is very punctual, friendly and courteous. Tim seems to be an expert in the installation/repair of hot water heaters. He will also try to help you save money in the future by offering tips to help in maintaining your existing equipment. I have relied on JOS. Fredericks & sons for all my HVAC needs for over 20 years and would recommend them and Tim R for all of your HVAC needs.

Definitely won't go anywhere else for future work.
