From the first call to Mark Krenn, owner of American Solar Energy Systems, to discuss my options for replacing my conventional hot water heater with a much less expensive to operate heat pump water heater, I knew I had found a contractor I could count on. No pushy sales, no bad vibes, just calm experience and knowledge of the product he installs. I was considering a Rheem ProTerra system until he convinced me of the quality and support provided by Bradford White. I ended up going with an 80-gallon model to support the needs of my home. I was given an incredibly fair price - thousands less than the larger local marketplace competitors - that was backed up by an extremely competent installation. The whole while, Mark kept in touch with me, answered my MANY questions, and offered sage advice where it was warranted. I absolutely cannot recommend him enough. He has over 40 years of experience in the business of low-energy hot water systems and knows the technology inside and out. He worked cleanly and efficiently while respecting our space and we ended up with a beautifully finished installation. Give him a call. You won't be disappointed.
Ricky, thank you very much for such a glowing review! I do very little advertising so the #1 source of new business for my company is word-of-mouth referrals and testimonials from satisfied customers like you. It was a real pleasure working with you and please let me know if there’s ever anything I can do for you.
Mark was very knowledgeable and helpful!
Thank you Julie! Glad I could help
Had new solar panel system installed along with a new efficient hybrid water heater. Mark helped us get a system to maximize our power generation while staying within JPL's tier 1 limit (10kw). . There were a few hiccups with condensation and draining for the new water heater which took a 2 visits to address. Now everything is installed and up and running smoothly, my system generates about 20kwh on a cloudy day up to 50kwh on a sunny day and this is only November. I expect this to be a great investment for the future,<br><br>I am currently working with Mark to resolve issues with my system.
Mr. Jenkins, thank you very much for the positive review! Looking forward to working with you to get your system back in perfect condition.
Excellent company and seamless experience. I highly recommend!
Thank you, Donna, for the great review and of course, thanks again for your business!
American Solar did an outstanding job doing my replacement panels.
Thank you for the excellent review, Tim, it is very much appreciated.
I’ve been doing business with American Solar for over 11 years, and that kind of long-term relationship says a lot. In my experience, they are extremely trustworthy. They do exactly what they say they are going to do every time. That consistency and integrity are what set them apart.<br><br>Over the years they’ve proven to be reliable in every respect of their work. Projects are completed as promised, timelines are met, and there are no surprises along the way.<br><br>Their customer service is also been outstanding. They’re responsive, professional, and generally care about their customers long after the initial installation is complete.<br><br>Just as important, the product itself has been excellent. The system has performed well overtime, and I feel confident I received a high-quality solution and a fair price.<br><br>It’s rare to find a company that delivers this level of honesty, reliability, service, and value over more than a decade. I would highly recommend American Solar to anyone considering heating their pool.
Mr. Kenyon, thank you very much for your kind and thoughtful review. It is very much appreciated!
This is our second time dealing with Mark at American Solar Energy Systems. After 17 years and many storms our solar panels Mark installed decided enough is enough as a hole developed in the panels. We decided to go with a heat pump and gotten several quotes. Dealing with Mark in the past was great and easy which was a factor in our decision. We ended up having Mark install a heat/cool pump.
Lee, thank you very much for your business and the great review! It was a pleasure doing business with you.
