“Andrew and Matt were outstanding! They were professional, knowledgeable, and courteous throughout the entire service call. They replaced a couple of fan control switches that I had ordered directly from the fan manufacturer and completed the work efficiently and with great attention to detail.
They kept the work area clean, thoroughly tested everything, and verified that all the fans and controls were operating exactly as designed before leaving. They also took the time to answer all of my questions and made sure I was completely satisfied with the results.
I truly appreciate their professionalism and quality workmanship. I would highly recommend Andrew and Matt to anyone looking for reliable and skilled technicians. Great job!”

“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.”
“Joseph Frederick & Sons has been servicing my HVAV and plumbing needs for years. They always do a fantastic job with installations, maintenance, and repairs. Their entire team is friendly, knowledgeable, prompt, and professional. You're in good hands from the time you call in to make an appointment until the job is completed. This time, Tim R did an awesome job repairing our tankless water heater. Hot water is once again flowing through our pipes. Thank you, Tim R and Joseph Frederick & Sons.”
“Aaron always does a great job, informative and personable and honest.”
“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.”
“⭐⭐⭐⭐⭐ 5 Stars
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!”
