"Andy and his helper were INCREDIBLY respectful, punctual, and competent. Andy showed me what was wrong with my leaking shower head before/after repair and stepped me through the whole process. The total cost was cheaper compared to other plumbers and he took the time to show me how I could prevent other water damage in my shower stall. He made sure everything was cleaned up afterwards. More importantly, he was very nice and easy to work with. I highly recommend his services for any plumbing repairs."

"This was a last second thing. Our hot water heater died on us. Left him a message on Tuesday afternoon. He showed up first thing next morning. Right on time. Discussed the job and he gave me a estimate with a small window. And he said he could have me back with hot water in a few hours. Sure enough less then 3 hours later I’m back running. Very good and clean job. Very professional with all aspects of the job which was nice. Best part of it all when it’s time to pay his his price was barely over the low end of his estimate. Everyone else would most likely been barely under the top end of their estimate. So a very good clean job done as a rush for a good price."

"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."

Water Heaters FAQs, answered by experts

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

Choosing between an electric water heater vs. a gas water heater comes down to personal preference. Overall, electric heaters are more energy efficient than their gas competitors. They’re also quieter to operate, take up less room, and don’t come with a risk of gas leaks. 

The downside is that electric water heaters cost more to operate than gas. They might also struggle to heat water fast enough for households that use large amounts of hot water. Lastly, a power outage could cause your electric water heater to stop working, whereas gas water heaters may still function.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

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.
