"I had good service from previous plumbing repairs but they really messed up on my A/C repair this time. I was 3 weeks without air during one of the hottest periods this year. The first motor that was installed broke the same day it was installed. 7 day wait for another one. The job cost me almost $1100."

"I cannot say enough about Aaron Schwarder and Schwarder Construction. We bought a home that had not been updated since 1964. Plumbing included. Aarons crews redid both baths and the kitchen. Beautiful bright Carrera look tile, white counter tops, beadboard, wainscoting. New light and plumbing fixtures. Kitchen went from dark and cave like with fluorescent lights in plexiglass recessed ceiling thing, to raised ceiling, high end appliances, beadboard cabinets and an open to the dining room floor plan. Aaron was not satisfied with the cabinet surfaces and repainted them himself. All custom cabinets. Very important to me is the comfort level of having people working in my home. It can be awkward, to say the least. Aaron's guys are very respectful and always clean up at the end of the day, even if they are coming back in the morning. They were very careful not to let the animals escape. Recently I called the home depot pro desk with some questions about installing a new entry door and the first name they gave me was Schwarder Construction. I was raised to believe that a man's word is his worth. You can take Aaron at his word. 5 stars only because you cannot rate higher."

"I've been using this company off and on for several years. They aren't the least expensive, but I'll tell you, they are the best! I have a vacation rental and a sump pump...not a good combination. Last night, the guest reported sewage backing into the shower and bathtub. I got in touch with Beverly at 8 a.m., and she had someone at the house by 9:30. Beverly has always taken my calls these past few years, and she feels like a family member who is there to help. She is always helpful and talks me off a ledge when I'm stressed about a plumbing issue. Thank you, Beverly! Ryan was my service tech, and, like all their staff, he was prompt, courteous, and professional. He informed me about each step and took pictures to show me what the problem was and the resolution. He handled a disgusting job that almost all people would not touch. They resolved my issue, and my current guest was very happy. Thanks for digging out all the grease that prior guests have dumped down the sink. Not a good combo with the sump pump and plumbing. Happy Holidays to all!"

Water Heaters questions, answered by experts

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.

Unusual noises, lack of hot water supply, efficiency loss, and visible leaks are signs of necessary replacement beyond mere repair.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.
