"Tap Heating and Cooling came while I was at work and my wife was home taking care of our newborn.  The technician, Jeff, was very polite and very quiet as well (as we had a newborn sleeping) which I found to be amazingly courteous.  He performed the cleaning and inspection of our furnace very quickly and efficiently.  When Jeff was finished, he let my wife know the the circuit board was mounted improperly, but that he went ahead and took care of it as it was a very simple fix.  As well, a filter was included in this service.  I had recently replaced our filter (not realizing I was going to take advantage of this awesome Angie's List deal) and he let my wife know that the filter was still good and that he left a new one next to the furnace for next time.  We recently moved here, but Tap Heating and Cooling is for sure my go-to in the area from now on as they showed nothing but professionalism, honesty, and courteousness while in my home.  Thanks Jeff and Tap Heating and Cooling, I'll see you in summer for my A/C tune up!

"We bought a house recently. The inspection report called for installation of an expansion tank and lengthened drip leg on the HW heater. Jamison Plumbing had installed the new HW tank several months before for the original home owner. Jason called the City of Liberty to determine the exact code requirements. He called back and agreed to the additional work at no charge. He was able to make the changes in a timely manner. His crew called to say they would be later than planned because of an unexpected delay at the preceding job site. We appreciated his willingness to finish the installation according to code and to cover the additional materials and time. It was a great way to be welcomed into a new community.

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

"I called in at 2:30 AM and ii got an answering machine. I had left messages at 2 other companies so I thought "what the heck, I might as well see if this company will return my call." With-in 10 min I had a call back and they had a tech out witth-in the hour. The man I spoke with on the phone went through step by step what I needed to do to shut off the water because it was leaking all over my floor. They were prompt and had wonderful customer service. The tech had a badge on with his picture and the company name which made me feel very secure to let them into my home in the middle of the night. I can not say enugh about Reeds 24HR Plumbing. I would use them again and would definatlty recommend them to my friends and family. OH and the cost was very reasonable for having to come out in the middle of the night! I received a courtesy call the very next day to check on how things went and if there was anything else they could do for me. THANK You Reeds And to the professional Tech Scott that did a super job.

"They were up right and direct to the point. Had some trouble with the fittings so took longer then expected. Made up for not having correct fitting by lowering the cost, clean up really good, and disposed of old water heater at no cost. I'm well please with the service. Mike"

Water Heaters FAQs, answered by experts

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.
