"Great. The contractor from Jimmy Gusky arrived on time and within 45 minutes had provided a full inspection and determined the unit was fine and had simply malfunctioned temporarily during several extremely hot day.s. So this saved me many thousands of dollars. Great experience."

"Fred was responsive (same day), courteous and professional, got to work immediately and was quick and efficient.  He gave me thoughtful advice as well regarding getting maximum life out of my appliances-I solicited him on replacing my water heater vs the other way around.  Pricing was very reasonable.  Highly recommend.

"Jamie our plumber arrived right on time & very efficiently performed three jobs for us. These included replacing a kitchen disposal, installing a vanity water faucet, flushing the water heater. He patiently explained each task and stayed until all were completed. We were so pleased we've entered into a service contract with Beacon Home Services."

"Woke up this morning to my hvac leaking and contacted Markool. I have never used them before and was in a pinch. They fit me right in this morning and were out at my house within 2 hours. The tech stepped in the door and placed covers for his shoes so he did not track in any dirt which was impressive! The tech was very professional and super friendly. Problem was diagnosed and FIXED within an hour. The price was extremely reasonable to the point I was shocked in a good way (expecting a higher price). Anyways, I will most certainly be a returning customer. Thank you Markool Heating Cooling Plumbing."

"Mr. Rema arrived on time Sunday morning to update my water heater. He installed an expansion tank, duct work and replacing the piping to the thermostat on the water heater. He did an excellent job and took his time. Mr. Rema also went to the local hardware store twice to pick up the material that was needed. The only reason I didn't give him an A was because he quoted me a price at the beginning and then went done on the price and then tried to go back up to the original quoted price. After talking with him he decided to keep the price at the lower amount that he quoted."

"Hired Pohlman to evaluate two natural gas tank water heaters in our home, one of which was unoperational. They suggested combi-boiler for our home in lieu of two tank water heaters. They did a great job and we are very pleased. Customer service is top notch, and I highly recommend Pohlman Plumbing."

"Joseph Plumbing and Drain replaced our aging (21 year old) Rheem water heater with an AO Smith Proline 50 gal model. Kap, the owner of the firm, came out to give us an on-site estimate and a detailed explanation of the work to be performed. He showed up at 9:00 am two days later to do exactly what he had promised. Of the six different proposals that we reviewed, Joseph Plumbing and Drain came out on top. They were neither the lowest nor the highest bid, but in our view, the best bid. We found Kap’s price reasonable, his knowledge comprehensive and his work thoroughly professional. We felt we got a quality water heater and expert installation at a fair price."

Water Heaters FAQs, answered by experts

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a local professional to install a water heater, this expert will ensure you follow all the local regulations.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.
