"My heat pump which had been installed 2 years ago by FH Furr suddenly stopped working Sunday afternoon. With the heat warnings in effect, I knew I needed help, FAST! Blair arrived this morning abd diagnosed the issue and replaced the condensation pump. These new "smart" systems have more brains than some humans!! When the pump failed, it shut down the entire system. However, Blair had the old school know-how and work ethic to get my system back online and back to normal. I have seen a nice change in technicians in the last 2 years and am always pleased to have them come out and fix any issues I may have. Keep up the good work!!"

"I was nervous to check on water systems for our house and am happy I found Purfect Water Solutions. After checking through Angie's list I got an immediate response and scheduled a time to meet with Scott. He came in and tested the water, he educated us on where our water quality is now (not great) and even tested our bottled water we got from the store (which was also not great). Great financing program if you worried about $ and referral program. W/ what we pay for water this was a no brainer. John came by our house in days with the system and had it hooked up the same morning. He was very nice, punctual, respectful and knowledgeable with what he is doing. I don't usually write reviews... but we want safe water for our kids and family and Scott & John did such a great job I want to write a good review and share our experience. Water is so important everyday. Do yourself a favor and at least get your water tested so you know what your family is drinking/washing with."

"The project was completed seamlessly and Jim and his helpers were competent, hard-working and didn't mind explaining what was going on every step of the way! His years of experience are evident, and make him a great diagnostician and problem-solver. He even went out to buy stone to line the bottom of the trench dug outside of the house to insure that the new pipe would be stabilized underneath! There were a number of things that could have been complications (like tree roots, and breaks in the pipes going to the septic tank), but it was clear to me that Jim would be able to address them, if they did surface. This was the kind of thing that makes a homeowner very nervous, so I was so relieved that I had Jim do this work. Experienced, competent, honorable, and a really nice guy! So glad that I won't have to conduct searches for a plumber in the future!"

Water Heaters FAQs, answered by experts

Storage, tankless, heat pumps, and solar water heaters each suit specific space constraints, usage needs, and efficiency preferences.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

Traditional gas or electric water heaters last an average of six to 11 years. However, with excellent maintenance, they can last up to 15 years. Heat pump water heaters, on the other hand, last an average of between 12 and 15 years and potentially longer with proper maintenance. In both cases, your home's water quality can be a determining factor regarding the lifespan of your water heater.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener.
