Best Heater Repair in Phoenix AZ

I have an antifreeze (closed) solar water heater that was having some issues.  General solar came out and resolved my issue quicker and easier than I expected.  Turns out all I needed was a system recharge. Perhaps best of all, the cost was very reasonable.  
They did a good job of checking thoroughly for other possible issues, but also didn't make me feel like they were trying to push any unnecessary repairs on me.  They were attentive to making sure the job was done right.  Customer service was great and they explained in great detail what was going on, and were friendly but professional and knowledgeable.   Considering that my biggest complaint was that they were about 15 minutes late, it was a great visit.

Pedro arrived when he said he would.He was professional and knowledgeable and went above and beyond to address all my electrical issues in a friendly and trustworthy way.I will definitely call them again !

Great service from Nick and his company, I literally texted him nextdoor this morning, he responded very fast, and was at my house in 2 hours to fix our AC unit, now it starts and operates much better, much quieter. Thank you very much, wish you and your company all the best...Vince (U.S. Navy (retired))

Kelly at EOS was so easy to talk to and extremely knowledgeable. I ended up going with them for the higher efficiency panels I'd wanted for our current system. They made the whole process so easy. After looking around for fair price and the ability to install quickly; they came up with awesome pricing and actually listen to me. No one tried to BS me into more than I needed or wanted. They spent time answering my questions, and never talked over my head (so refreshing). They got me installed within two weeks of first contact! The new panels look great and you can tell the installer Chris loves what he does. Solar has saved me thousands and with these new added panels, I'm saving even more. Bye-bye APS, and thank you EOS! You're the best and I'm surly going to be sending everyone I know your way.

My husband found them on Angie's List and they did not disappoint. Outstanding customer service and attention to detail. They showed up on time, completed the job, passed the inspection, and cleaned up after themselves.  Extremely friendly and accommodating. We will definitely be using them for all our needs.

Fast response and was $300 lower than other companies. Will definitely use for any other plumbing issues.

Very fair pricing, excellent work.  Arrived on schedule and on time.  Extremely happy and highly recommend DTL Electric.

I started talking to Danielle about solar for our home since our electric bill was so high summer of 2019. She was so educated and had great customer service. Any question we had, she answered quickly. Brandon was also a pleasure to work with. He got our solar installed very quick after we made a great deal and he even threw in a free 65" tv to say thank you! Highly recommend Divine Solutions if you're thinking about buying solar for your home!

Very impressive service. They contacted us right away to schedule a visit for an in- person quote. Quote process was thorough and Rob was a real pleasure to work with. Quoted price was reasonable and the company is vet friendly. Installation occurred within mere days due to a cancellation, but expect about two weeks. The crew, including James and Eddie were great! Very friendly and Eddie's 20 years of pool experience was evident in the careful and meticulous work he did, even improving the current pump manifold configuration. They spent the entire day and checked and rechecked their work thoroughly. Our pool is already warming up and it was a true pleasure to work with this fine company and superb employees. Even the company founder, Jamie came by to meet us and check on the progress. Felix has my top endorsement!

This company is a DISGRACE and their customer service is HORRENDOUS...stay as far away as you can. My solar system had to be completely redone because of their incompetence(by a company that actually knew what they were doing)...don't believe a word they tell you!

Years ago Heliocol put solar hot water and pool solar on the roof. I was later told they should not have sold me the water heater solar, as I was on gas and the backup for their system is This will be in parts in Twitter due to limited number of characters.

Years ago Heliocol put solar hot water and pool solar on the roof. I was later told they should not have sold me the water heater solar, as I was on gas and the backup for their system is electric, much more expensive and reduces significantly any savings.
Five years ago all sort of green material coming through my faucets, shower heads ruined and all had to be replaced. Big expense I paid. Found out the rod in the tank completely disintegrated. Likely due to the hard water in AZ, but they should have known this since they are in AZ. Anyway, put in a different rod and seems to be fine.Told me to service every 4-5 years. I have called and left messages for service to call me back twice over the last ten days and sent an email request for service. Never even the decency to call me. Finally, reached Melody last Friday, explained the situation and she "promised" to get back to me Monday to arrange a service call. She never called, I called and left another message and still did not have the courtesy of calling me back. Do you really want to buy their products and not be able to get them serviced?
Horrible company!
In regard to the solar for the pool. Over time the small tubes spring leaks. Bad for the flat roof and the elastomeric coating. Each time I would call for a repair it would take two to three weeks for them to come out. In the meantime I had to turn off the solar so it did me no good. Finally, went on the roof with my pool guy and learned how to repair it ourselves. Stupid of Heliocol, now they lost all that money which I gladly paid when they did come out.
The company is horrible, they sell you things they should't, they don't return calls or come out to do the necessary service. ZERO STARS. Need I say more?

If this is posted they are really stupid and really don't care about their customers, since I was nice enough to send a copy of the above to their main office with a note to please have someone of a managers level or above call and rectify this situation. I have given them a week to respond and they must have decided not to......

Update as of 4/23/22
Received a call from Benjamin the day I wrote this initial review he promptly responded and let me know he was going to review my account information and would get back to me within a week. I have never received a call back and have left multiple messages over the last couple of months and sent a message via Yelp with no answer. I was excited about solar and during the initial sale they were helpful and routinely stated how it's a long term relationship we don't just sell you something and you never hear from us again. I don't usually write reviews but felt this one was important to share for awareness as solar is a financial investment so pretty disappointing to pay for solar and continue to have to pay APS bills every month that are over $100.
