  Excellent service from first inspection and estimates to the actual appliance installation.  Gabe Thomas was skilled, polite and friendly.  His plumbing installation was top-notch using the latest technology.  Our new water heater has worked flawlessly the past week.  I trust Jos Frederick & Sons to work at my home and will use their services in future as well as continuing my HVAC service contract.

  Dave went the extra mile in providing multiple options for our furnace and A/C replacement. The install crew - Jake, Jake, and Omar - were among the most knowledgeable and well-trained techs I  have dealt with. Everything installed professionally and right the first time. Highly recommended.

  Gabriel was professional, had clear communication and is highly competent. We had an issue that he quickly assessed and provided options. He performed his service and all works as expected. We were especially thankful he was willing to take our video call to discuss! Excellent technician! We were thankful for him to be able to come so quickly.

  Until the service call last week, I heartily recommended this company. I can no longer be a supporter. The tech was nice, but came without the necessary adapter to check the refrigerant level in my two compressors. He used my hose, but broke off the water flow meter attached to it - and did not tell me. When presented with the bill, my charge was twice as much as last year so I paid $332 for a one hour  service call, which is about double what I paid last year!!! I expressed my dissatisfaction to the tech. I have yet to hear back from the company. Life must be bounteous at Joseph Frederick and they obviously do not need my business. So, they will not and I surely will not recommend them.
