Medallion Energy
4.7Out of 5 starsOverall rating out of 80 Google reviews
Denise did a fantastic job helping isolate and identify an electrical issue. She worked directly with me throughout the troubleshooting process, demonstrating professionalism, patience, and a collaborative attitude as we checked various voltages. She provided logical explanations for the readings and offered a well-reasoned theory about the potential cause of the issue. Subsequent investigation confirmed that her speculations were correct. I was very impressed with her technical knowledge, methodical approach, and ability to work through the problem.
Google Review 5/5 Stars — Outstanding Service and Expert Guidance I cannot say enough good things about Medallion Energy. When I ran into an issue with my pool heat pump's control board, the owner, Jim Diroff, reached out to me personally to help work through it. Jim was extremely professional, courteous, and knowledgeable. He walked me step-by-step through troubleshooting the board, which helped us reach a clear conclusion: after 20+ years of faithful service, it was finally time to replace my old pool heater. Because of Jim's exceptional customer service, I am purchasing my new pool heater directly from Medallion Energy and having it shipped to Maryland. If you want honest advice, deep expertise, and a company that truly values its customers, look no further. Highly recommended!
I want to thank Medallion Energy for helping me getting my heat pump working again. The display said "FLO" despite adequate water moving through the system and I was sure that it was the water pressure control switch that needed replacement. After reaching out to them via email they called me back and asked me what was going on. After explaining the issue they agreed that it was most likely the switch and shipped me a new one. It even came with directions on how to replace it. Once replaced I turned the heater on and it is working again. That saved me a huge bill to replace the heater. Thanks Medallion Energy for your help.
AquaComfort stands behind their products and delivers exceptional service. My husband and I could not be more pleased with this company. The service team went above and beyond to fix our concerns even when the warranty was expired.

I had the temperature sensor on my electric heater fail and I worked with tech support (Nikki) who did an excellent job assisting me in clearing a code to get the heater running despite the failing sensor and said she would ship out a new temp sensor with complete instructions to accomplish the repair (if I felt comfortable doing it) or send a repair technician. I opted to do the repair myself. Took less than an hour and the directions were spot on and easy to follow. My heater is back working and the new sensor performing like new. My heater was still under warranty so no cost to me.Posted on Google![]()
