- Single component failure (capacitor, sensor, fan motor)
- You've maintained it regularly
- Major components are still healthy (compressor, heat exchanger)
REPLACEMENT
Makes Sense When
- Your heater is 10-12+ years old
- Facing a $1,500+ repair (compressor, heat exchanger)

I have a large pool 20 x 36 and Jacuzzi. Last year after consulting with Medallion I went with an Oasis Heat Pump to heat my pool. I can not say enough of how happy I am with the Company and with the Pool Heater. Great service and tech's on the installation and the heater works tremendously. This week, the first week of January, I turned on the heater and within 2 days raised my pool temperature from 62 degrees to 88 degrees. Excellent product and service. Highly recommend Medallion and the Oasis Heat Pump.
I recently called Medallion Energy to have a technician inspect my 10-year-old failed heat pump and provide an estimate for repairs. The initial quote for about $1,000 in parts and labor seemed reasonable, but what impressed me most was how the tech went above and beyond. Instead of just fixing the immediate issue, he continued to thoroughly check the entire system and discovered that the compressor was making noises indicating an impending failure—which would have led to a much more expensive breakdown later. They could have easily taken the $1,000 job and said nothing, but they chose honesty and transparency.The team walked me through several options, including a full unit replacement, and explained everything clearly. They were genuinely understanding, empathetic, and patient while discussing solutions with my wife and me. They even negotiated an outstanding deal that saved us significantly compared to what I'd researched on Google for similar heat pumps. The installation was flawless—they removed the old unit and professionally installed the new one in just one day. Afterward, they took the time to sit with us, walk through the controls, and show us how to customize the temperature settings for the pool and spa separately. My wife and I are absolutely thrilled with the care, professionalism, and support we received from Jim and Brandon. This level of honesty, expertise, and customer-focused service is rare these days. Medallion Energy truly stands out—thank you for making what could have been a stressful experience so positive! If you're dealing with pool/spa heating issues, look no further. Medallion Energy gets my highest recommendation!
Excellent company and service!
Thermostat not working on my pool heat pump...called customer service...the service was exceptional...friendly and very responsive..Entire team, Ricky, Shelley, Tiffany, Denise excellent. Denise walked me through a possible fix and it worked. Thank You.
The team was a great help. Helped me to get my heater working as well as walking me through the process after hours thanks again!!
Total scam. I put in a request through Aqua Comfort. These guys called. Ricky walked me through what he thought was issue over the phone. My heat pump actually was working when I turned on for him. I ordered parts anyway $425 just in case it was a fluke it was working but still happened again. Parts came I decided to return parts as my pump was still working fine. I decided to look them up in case I ever needed them. They charged me $234 for a $30 part and $174 for a $7 part. I called this morning to return. He forgot to tell me when I ordered that on the Docusign you to sign after you pay there are no returns or refunds. I would have been happy to paid some thing for the time on the phone with me taking my pump apart myself. But a 10x plus over charge is ridiculous.
Had an issue with my heater; pool company said I needed a new motherboard. Thanks to Denise at Medallion Energy was able to walk us through a fix! Thank you Denise!
Dear Medallion Energy Team, I wanted to extend my sincere thanks and appreciation for the exceptional service you provided. You went above and beyond to resolve my issue, and your dedication, professionalism, and willingness to help did not go unnoticed. It’s rare these days to find a company so committed to customer satisfaction, and I am truly grateful for the way you handled everything. You’ve earned my trust and my highest recommendation. With heartfelt thanks, Robert Guadagnoli ⸻ Let me know if you’d like to add any specific names or details.
Everyone was extremely professional and very helpful in getting our pool heater back up and running. Great team with expert skills that was able to pinpoint the problem & give us serval options on how to resolve. Cannot thank Jim, Tiffany, & the rest of the team at Medallion enough!
I had a great experience with help from Medallion Energy. They helped me obtain and install a new motherboard for my pool pump heater which I could never have done on my own. Denise talked me through it on the phone while I was literally inside the machine and she was extremely patient, friendly and helpful and all of the communications were clear and helpful and the new system lasted a long time!
Called Medallion’s main office in FL (from Virginia), unsure if they’d be able to help me many states away. I received a prompt call back and Denise helped me (I’m sure it was obvious I’m a pool heater neophyte) attempt to diagnose my problems over the phone. Once we established on-site work/review would be needed, Denise provided me with a local service partner’s contact info. I called the service provider and they came same day. I’m very impressed with their kindness, service and nationwide network. Highly recommend.
I have had multiple excellent experiences when contacting Medallion Energy for my pool heater. Jim and Shelley have always been both gracious, patient, resourceful and knowledgeable about my problem. I always feel confident that they will have the solution and they always have one. Thank you both for all of your help. You define great customer service.
Tiffany was amazing! Totally floored by her exceptional service. Saved me a ton of money with her support, patience and expertise.

FAQs
Can a pool heater be repaired?
Yes, most pool heaters can be repaired. Whether you have a heat pump, gas heater, or electric heater, common fixes include replacing capacitors ($200-$400), fan motors ($300-$600), sensors ($150-$300), or addressing refrigerant leaks ($400-$700). Even compressor failures can be repaired, though at $1,200-$2,000, replacement may make more sense for units over 10 years old. We’ll give you both options with honest guidance.
What is the average cost to repair a pool heater?
Pool heater repairs average $350, typically ranging from $150 to $800. Simple fixes like thermostats or capacitors cost $150-$400. Mid-range repairs (fan motors, control boards) run $300-$800. Major repairs (compressor replacements) cost $1,200-$2,500. Labor rates typically run $80-$120/hour plus parts.
How long does a pool heater last?
Pool heaters typically last 8-15 years depending on type and maintenance. Heat pumps last 10-15 years, gas heaters 5-10 years, and solar heaters 15-20 years. Florida’s year-round pool season means your heater works harder than those in seasonal climates, which can affect lifespan. Proper maintenance extends life significantly.
What's the most common problem with pool heat pumps?
Low water flow is the #1 issue causing heat pumps not to work. This is often due to dirty filters, closed valves, or clogged pump baskets. Other common pool heat pump issues include capacitor failures, thermostat problems, and low refrigerant.
How long does pool heat pump repair take?
Most heat pump repairs are completed same-day in 2-5 hours. Simple fixes (capacitors, sensors) often take less time. Major repairs (compressor replacement) may require 1-3 days if parts need ordering. We stock common parts for all major brands to minimize delays.
Is it worth repairing a pool heater?
Here’s our honest guidance: If repair costs exceed 40-50% of a new heater’s price, and your unit is 10+ years old, replacement usually makes better financial sense.
For heat pumps under 8 years or gas heaters under 5 years with minor repairs, fixing it makes perfect sense. You’ll avoid the higher cost of replacement and get several more years of service. We’ll run the numbers with you for YOUR specific situation.
Why is my pool heat pump running but not heating?
Common causes include insufficient water flow (40% of cases), low ambient air temperature – below 50°F, refrigerant issues, or thermostat miscalibration. Check your filter, ensure valves are open, and verify your thermostat is set above current pool temperature. Our diagnostic checklist above can help you identify the issue.
Can I DIY my pool heat pump repair?
Simple checks (filter cleaning, valve positions, breaker, thermostat settings) are safe DIY. However, refrigerant-related repairs require EPA 608 certification by law. Electrical and compressor work should always be handled by licensed professionals for safety, warranty protection, and code compliance.
Do you provide a warranty on pool heater repairs?
Yes. All labor is backed by our satisfaction guarantee. Parts come with manufacturer warranties (typically 1-2 years). If something fails within your warranty period, we’ll make it right at no additional cost.
What's the difference between a pool heater and a pool heat pump?
A heat pump IS a type of pool heater – it’s the most common type in Florida. Heat pumps use electricity to extract heat from the air and transfer it to pool water (very energy efficient). Gas heaters burn fuel to heat water directly (heats quickly but costs 3-5x more to operate). When Florida pool owners say ‘pool heater,’ they usually mean a pool heat pump.
