“AC needed repair while the weather was in the high 90s. Called for repair and Lucas was here within 20 minutes and my AC was running again within 10 minutes. I am so grateful.”

“I noticed water pooling in the floor where our condenser is located. A quick call to Frederick and they had a repairman out that afternoon. The problem was a dead condensate pump. It was replaced in about an hour. This is the kind of excellent customer service we've had from Frederick over the last 40 years. Their service personnel are always courteous and competent.”

I followed Grok’s recommendation and called Joseph A. Frederick and Sons for our 20-year-old air conditioner in Wilmington, Delaware. They responded quickly, and technician Lucas did an outstanding job. He diagnosed the issue, got us cooled off in no time, cleaned up thoroughly afterward, and explained everything clearly.
The service was excellent and well worth the investment. My wife, children, grandchildren, and I are very thankful for Lucas’s hard work and professionalism.
I strongly recommend Joseph A. Frederick and Sons!”

“Today, Lucas came to our home and blessed us with a complete repair for our children and grandchildren. Lucas was able to work around our dogs, cats, and even the mice that were in the air-conditioning unit. What an outstanding young man to be sending out to your customers. Thank you so much, Lucas!”

“Lucas identified our issue in minutes. He shared the process of ordering a replacement part and returned to install and check our A/C was cooling properly. He kept me informed of what was needed and was very professional during the process. Great work!”

“We were very happy with the installation of our air conditioner and heater. Both Lucas and Jacob were very efficient and knowledgeable in the installation. We have been using Jos Frederick and Sons for the past 33 years and have been very pleased with the high quality service they provide. They install high reliable appliances and provide long warranty. Also, our experience in their plumbing services are highly recommended. Finally, Jos Frederick prices are reasonable and scheduling with their staff is friendly and prompt.”

“Lucas did a great job performing a deep clean /tune up of my mini split A/C unit. He was very cordial and showed me how dirty the internal fan had gotten. He even vacuumed area where he worked and also cleaned out sink he used to clean the dirty fan. As always I highly recommend Joseph Fredricks for any HVAC needs.”

“We use Jos. Frederick & Sons to service our full house air conditioner. They did the installation and we have always used them to maintain the system. They are always on time and the teck is always respectful and friendly and performs all the service points listed in our maintenance agreement.
We have also used this company for electrical and plumging problems. The techs who came out to resolve those issue were also respectful, friendly and resolved the problem.
For whatever reason we have JF & S come out, they are reasonablly priced and we have never had to have them return, because the job was not completed & resolved.
My husband and I absolutely recommend JF & S.”

“I Do Not Recommend Jos Frederick for any service! They do not guarantee customer satisfaction, they are more expensive than most, not reputable. Carrier system less than 3 yrs old, installed by Jos Frederick. 5:30am no heat. Snow storm coming. Came out $125 emergency. 4 hours said it would cost $187 to repair. Labor not covered. No heat 2 more times. Again said $189 for labor for defective part. Why don’t they go back to carrier and have them pay the ridiculous fee of $189? Told them to fix. No choice.”
