"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!!"

"After leaving a message on Angie's List on Saturday, Jim Stephens responded within an hour or so. After exchanging information, he volunteered to make a service call the next day Sunday. Because of my 5-day work week, this was a big relief. On Sunday, he called, as agreed, and asked if he could be at my house in a few minutes. As agreed, he arrived promptly. He diagnosed the problems and, at my request, provided details for solution fix. He had the part in his van and explained how the fix would be done and how it would work. He answered questions and explained clearly and thoroughly. Before beginning the work, he gave me an estimate, which I agreed to. After the work, his stated charge was no more than what his estimate had been. In addition to providing a high-quality solution, he provided, at my request, education about a related issue - the exterior drain for the sump pump. He thoroughly explained how the exterior drain could be extended away from the house to mitigate the fact that the water flow was eroding the soil near the foundation. When Jim left, I was a completely happy customer. I knew that 1) it was not necessary to replace the sump pump and 2) I had the knowledge, going forward, to know how to routinely check and maintain the sump pump functionality. Without hesitation, I can honestly say I will be calling JM Stephens for all my plumbing issues in the future."

Water Heaters FAQs, answered by experts

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater’s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500

There are many issues that can cause cold showers, but the most likely is a problem with your water heater, especially if other fixtures also don’t get hot water. If it’s just your shower not getting hot water, you likely have a broken or damaged shower cartridge. You can replace this yourself or hire a plumber to do the work for you if you’re not comfortable working with plumbing.
