Sean arrived on time and was super professional. He evaluated my AC system post a home inspection that requested an evaluation and test for leaks. He did an outstanding job and vetted my system for my buyer. Thanks so much, Sean!

After poor experiences with Horizon I took the suggestion of Nextdoor reviews and went with J Frederick and Sons for an Hvac issue. I have now used them for 3 separate repairs/maintenance in my home including Heat, AC and Plumbing. All have been speedy, extremely reasonably priced and accompanied by polite knowledgeable service providers - Sean (HVAC) & Justin (plumbing). I am usually a do-it-yourselfer and hate spending money on repairs (especially when I am getting ripped off) but the service and bang for your buck with these guys is undeniable.

Excellent service. He was on time and very neat. He took the time to explain everything and to answer all of my questions. I have a 18 year old unit and he tries to keep the unit running rather than hard sell me on a new system.

Excellent service from a very conscientious technician. We met Sean E. when we first started using Jos. Frederick and were very pleased when he was the tech today. He does a very thorough job and fully explains all his recommendations.

Tim, from Joseph Frederick & Sons, and his partner, Dan, where courteous and great listeners. They quickly got to the root of my problem and solved it within a few minutes. Sadly, there was water damage, but they set my mind at ease by providing a referral to a company that will mitigate the damages while working with my insurance company. Dan took it upon himself to make the referral and I had the next step to solving my longer term issues scheduled before he left. PS They remembered to put on their booties - which is helpful given the dirt and pollen outside at this time of year.

I called Jos. Fredrick & Sons for an emergency electrical problem on a Friday evening. Steven O. returned the "on call" message and was polite when I spoke to him on the phone. He was upfront with pricing and made sure I was clear about how the emergency service call would work. He arrived within 30 - 40 minutes from the time I spoke to him on the phone. He was able to find and fix the issue without it going to a "next level" service call where he would have had to run test to find the issue, which would have cost more money. Steven was professional, polite, keep me informed and fixed my problem! Thanks Steven for a job well done!

I had sparks coming out of a light switch panel, so I called and found out that their electrician was on an all day job. Their electrician, Steve, came out to my house after his work was over for the day, replaced the broken component causing the sparks, and got all of the lights in working order. He was at my house late, missing time with his own family. I've always had great service with Joseph Frederick and Sons.
