“Our water heater needed to be replaced because it was leaking due to age and Dennis came over on a holiday weekend and installed a new one, he did a great job and cleaned up nicely. We have been with Jos. Frederick & Sons for years and are always happy with their service.”

“Joseph Frederick & Sons provided excellent customer service in walking us through the energy rebate eligibility, purchase & installation process. It was easy and affordable. They installed a mini split heat pump system in one day. I trust them with maintaining all of my HVAC equipment.”

“It was an exemplary experience having Anthony L. diagnose the issue and make the repair. Anthony L. is the consummate professional and expert in his craft. He is knowledgeable, technically proficient, highly communicative throughout all aspects of the job; from plainly explaining the issue, the repair, the estimate and informing me of progress. He is personable, courteous, honest, efficient and respectful of property. I will definitely ask for Anthony L. when I need plumbing services. Thank you Anthony and much appreciated!”

“After working well for 10 years, I had an issue with my AC – fan was operating but air was not cold. I called Jos Frederick in the morning and Lucas arrived around noon. The visit couldn't have gone better – he quickly found the problem and fixed it. The unit was literally on the final day of its warranty, so the replacement part was free and the labor cost was low because it was a quick fix. AC is working again – five stars for the company and the technician – they earned it.”

“I woke up Sunday morning to water here and there in my basement. I was suspicious that the water was from my water heater, since it was ~23 yrs old. I called Joseph Frederick and the answering service picked up the call. The woman I spoke with took all the needed information and told me a technician would reach out to me soon. About 15 mins. later, Gabriel called me, asked for a recap of what was wrong, and said he was on a job at present and would be to my house in 2.5-3 hrs. This was 9:30am, and Gabriel called me around 11:45 am and said he would be at my house in 15-20 mins. He arrived around noon, assessed the situation, and said he would need to go back to the warehouse and pick up a new water heater. He reviewed pricing with me, and off he went to pickup the new unit. Gabriel worked diligently from 1:30pm-4:15pm. He even cleaned up some of the residual water.
We've been using Joseph Frederick since 1986 and they never disappoint. The technicians are always courteous and willing to go the extra mile. I have a contract with them, and will continue using them for my HVAC needs for as long as I own a home.
Thank you, Gabriel, and thank you, Joseph Frederick & Sons, for a job well done … not just this time – but ALWAYS!!”
