We have been using Joseph Frederick and sons for 15 years and they NEVER disappoint. Our AC went out yesterday and they fixed it promptly today without issue! The office staff answering the phones are knowledgeable and friendly. Kevin (who typically does our service) is the absolute BEST!! He will stay late at work to be able to squeeze us in. The epitome of professional! Thanks :-)

They are the best company they’ve been open since 1947 fair and balanced and I will not use anybody but them for all of my home services

Sean was so polite. He made me feel comfortable with what was going on. Real nice guy. Figured out the problem in 2 minutes and fixed our problem within 20 minutes.

Joseph Frederick and Sons installed our new HVAC system. It didn’t work as expected, but they were committed to making us happy! They certainly went above and beyond to make sure the new equipment was working properly and that everything in our old house was done correctly (which of course it wasn’t!). Their dedication and professionalism was wonderful.In addition, their service techs are wonderful. They know what they’re doing, and are very friendly and willing to answer questions.

Always a pleasure with Joseph Frederick & Sons! Sean was prompt, patient, efficient, informative and most importantly friendly with our pup!

We are always happy with Joseph Frederick and Sons service. Their electricians so quality work and are so thorough and professional. They are our go to for honest, and hard working professionals!

Sean took care of us and got us up and running in an unfortunate bad timing breakdown and we thank him and the Joseph Frederick and sons HVAC manager . Awesome

Joseph Frederick and Sons does what it takes to get the job done. Our tech came out 3 times when our issue didnt resolve after the first visit, and we were only charged for the service fee for the first visit.

They were super amazing! They were very thorough and very professional. Would highly recommend! They were great to my family and pets. Felt safe having them in my home.

I had an issue on a Sunday with the heating system not working. This was during the winter, they came within a few hours and had it up and running in no time. Sean was outstanding to work with .

In short, great service. The customer rep told me the tech would be out at my house between 12 and 4. The customer rep called me on the day of the appointment to say the tech was on his way. Kevin Betts came out to do maintenance on my heat pump and to resolve a humidifier problem. Kevin did an excellent job of explaining what he did, why he was doing it, and what I could do in the future. He did an excellent job! If youre going with Jos Frederick & Sons, I would recommend asking for Kevin to be your tech. Great communication, great work, very friendly!

Excellent experience. First Bobby came to service my furnace. He was friendly and courteous. Given the age of my furnace, we discussed installing a new one. No pressure. I was the one who brought it up. The new furnace was installed in a few hour and at a MUCH lower cost than my other bids for a brand-name unit. I highly recommend this company.

Have used them twice, both times service provided has been excellent and all staff I interacted with was very professional

My 15-year-old AC began to fail just before the beginning of a predicted long and severe heat wave. After doing some quick but extensive research into repair vs. replace, and into the various makes, models, and installers, I decided ultimately to purchase a new Carrier AC from Jos. Frederick & Sons. My decision was based in large part on my having had the pleasure to work with Mr. Bud Thompson, who I found to be very professional, knowledgeable, and forthright. I felt that he was truly advising me rather than just trying to sell to me. The AC was installed in just a couple of days and it has performed flawlessly since. Thank you Bud, for all your advice and help, and thank you Jeff and Rudy for doing such a great job on the installation!

Tim did a fantastic job today. He diagnosed the problem quickly and fixed it efficiently. He was very knowledgeable and professional. This company has done plumbing and HVAC work on our home and we could not speak more highly of them.

Really great experiences. They are flexible and great at communicating. I recommend them to anyone who asks.

I was disappointed. My father pays for the service plan for his heater. I called them when he had a water leak that had the water turned off in his house. He is 85 years old so no water is an issue. They said they could not schedule him until December.

Steve, the electrician at Joseph Frederick & Sons, analyzed our project needs, estimated and installed 4 new electrical circuits in our basement. Steve is very knowledgeable and provided detailed answers to all my questions, His work is very professional, very neat and carefully checked. It was a pleasure to have Steve for this project.

Sean is the best technician that has serviced my heater and air conditioner systems. Very thorough, explains everything and goes above and beyond. I will certainly request him for my future needs. Outstanding.

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!

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 clients 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.

I have only experienced excellent service with this company. Theyve done many installations for us, all on time/budget, and my house is left exactly the way they found it. Like many homeowners weve experienced our fair share of plumbing issues, and they are always responsive, knowledgeable, and fix the problems for a fair price. This is a great family-owned company that cares about their clients. I highly recommend them.

In a hot house Aaron shows up and make it all go away. Personable, Kind, informative and results driven. Aaron really does what it takes to make it, teach it and help. Thank you Aaron. We will all sleep a lot better tonight.

Emphasis on superior service and customer care. Prices and contracts are reasonably priced.

Huge shout out to Jos Frederick & Sons for their excellent customer service. Im so pleased that I chose you to replace my new hvac unit. From David the salesman to Bruce the installation manager to the installers and the receptionist answering the phone, you guys/gal are terrific. God bless all of you!

Quick service. Very knowledgeable, excellent service, very professional.

The beginning of Summer woke up and had no AC. Have 94 year old Grandmother living with us. Called 4 24 Hour Service companies. 2 left message no answer never heard back, 1 called back next day and Joseph Fredrick & Sons I left message and had a return call in under 10 minutes and Tech was at house in about an hour. He was able to fix problem unit was frozen up. Had to let unit sit to defrost told me to turn back on when defrosted and if any problem call him back. Was very impressed when I got a follow up call from him latter that day to make sure unit was back on and running OK. A lot less then I expected to pay for a Service call on weekend and Tech was top notch.Last Night had no hot water went to water heater and it was leaking on floor. Call Joseph Fredrick & Sons 7:30 in am spoke to very nice lady that said she would put me on the schedule for today but not sure when they would be able to get out due to call volume and they would call when on their way. Got a call at 9am saying someone was on their way was there a few minutes latter. He wrote up an estimate for new water heater and install and started job immediately.Excellent Customer Service and Workmanship will never use any one but Joseph Fredrick & Sons in the future. Great service for a very reasonable price.

I had a problem with my heater not working and Fredrick & son made a ernest effort to fit me into the work day last minute, It was cold and calling to get colder & snow over the next couple days, the tech came out and diagnosed the possible problem, ordered the parts and returned a couple days later once the special order parts arrived and he installed the necessary part and things have been working fine ever since .It was nice to hear we can fix this ... AND NOT your going to need a new heater ........would recommend to anyone --- yes

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. Ive always had great service with Joseph Frederick and Sons.

Ken was probably the best service person we have ever dealt with, honestly.Based on how thorough he was and how he took lots of time to explain everything to us, we will be giving ALL of our business to this company and will recommend them to everyone we know.

They were super professional and did a great job! They worked around my crazy family!

They are just the best. Why? First their prices for skilled labor are absolutely fair and the time estimates reliable. No surprises. They don’t jack up the prices when your sweltering or freezing and everybody else’s units are breaking down too. Second, they are honest and stand behind what they sell. My unit 9 years old and needed a fancy new DC variable speed blower motor, read expensive almost $1000 just for the part. It was even my own darn fault for not changing filters often enough. One call and all taken care of under warranty, when another company was quoting me over $2500 to replace motor and Fredrick charged me just $571 for the labor part, which was out of warranty. A 5-10 year warranty that I had forgotten about. So the other company was quoting me double on a fair price for parts and labor if out of warranty! So yes, Fredrick is honest. I don’t know why I didn’t call them first. You think it’s because they don’t spend a fortune on advertising, so they don’t have to charge twice the fair price? Thank God I had that, I rarely buy warranties, but expensive high tech units I used for the top floor of my house I did. Gas furnace and single speed AC for main house, heat pump with variable speed motor for top floor since air handler in attic space. That unit you can set not only temperature, but humidity too. This is great because humidity wicks through your whole house fast. Controlling humidity makes for greater comfort for less energy. That’s why some AC’s can make you feel cold and clammy, you dropped the temperature, but still have too much humidity. Instead, the unit will run at an optimum rate to drop the humidity without over cooling. Like a giant dehumidifier, you are more comfortable at a higher temperature. Third, they know what they are doing and are at the top of their game. This is so important and getting harder to find in businesses. The system they sold me 9 years ago is still tops for efficiency and high tech features. If I replaced it today, the latest and greatest wouldn’t buy me much extra efficiency. The units, most advanced at the time, have stayed up to date. I can run the bedrooms and shut down the lower part of house at night saving me huge in energy cost. We spent extra money for these features, but we spent it where is counted and made economic sense as well as high performance. Very pleased with the system they put together for me. I’m an engineer, so I know what I’m doing too. Forth, they are all very nice people! From the phone to the service techs, they are warm, friendly, cooperative, skilled and willing to work with you. You can tell your dealing with a family owned business that has happy employees.

Just had our new heat pump unit and inside unit installed. Could not have had a better service crew do the install. Jeff and Tyler where very good. Professional, courtious and answered all my questions.

Aaron could not have been more customer oriented. He made it easy on me and was prompt and respectful. Thank you!

DO NOT USE. RATES ARE COMPLETELY UNREASONABLE. CHARGED $600 TO SWEAT 6 INCHES OF COPPER AND REFILL THE LINES WITH WATER. NOT EVEN 3 HOURS OF WORK. THAN ADDED $79 FOR A DISPATCH FEE. THE TECH DIDNT EVEN SWEAT THE COPPER RIGHT THE FIRST TIME. TOOK ADVANTAGE OF MY HONESTY THAT OTHER HEATING COMPANIES TOLD ME THEY WOULD NOT REPAIR THE BASEBOARD COPPER PIPE. WILL NEVER USE AGAIN.

They do the absolute best when servicing my equipment and repairing plumbing issues. And the customer service is excellent. I love this company!

Had an electric problem. JF&S correctly identified it as a Delmarva issue and indeed it was. Delmarva came out and my problem is solved. Very knowledgeable staff. They hit the nail on the head and were able to come out quickly. 5 stars! Will call again!

Great service and friendly people

Timely. Professional. Clean. Thorough

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.

Prompt,super friendly service. Would definitely work with them again.

Aaron did the annual maintenance on the heater and found faulty burner units. He was very professional in explaining the issue and the corrective plan. He returned with the parts and fixed the CO problem.

Our heater wasnt working Wednesday night. I had called 3 other 24-hour service places. The earliest they could come out (if I talked to anyone) was the next day after noon. I called Joseph Frederick and Sons, spoke to an operator who took my info and I received a call from the technician on call, Aaron, within 20 minutes. While on the phone he walked me through some troubleshooting and sure enough, it was a just a switch on the furnace that needed to be turned back on. Aaron took the time on the phone and saved us the huge expense of an emergency visit just to flick a switch - and as a bonus, he was very kind and pleasant! We have had a service contract with another company in the recent past; however, we will not be going back to them. We will be using Joseph Frederick & Sons from now on! Thank you for the great service, Aaron!

Have used this company for all my heating and a/c needs for over a decade. Excellent service and personnel.

Excellent service and very helpful and friendly technicians. Always punctual on service calls. If anything goes wrong they make it right.

Always professional after all these years. Excellent customer service and fair prices.

Kevin is friendly, polite, helpful and very good at his job. He is a credit to Jos. Fredricks and himself.That says it all .

Bobby,Very thorough and courteous. Reviewed all the service done when finished.

Excellent technician - smart and professional.
