"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"Excellent Plumbing was fantastic - he installed a new faucet, vanity, and water filter for me. Super punctual, really professional, very communicative, and paid close attention to detail. Everything's working great. What really stood out was Joe's dedication. He came back to check on the work and found an unrelated issue with my kitchen sink (which was already there). He gave me some great tips on how to fix it. I highly recommend Joe and Excellent Plumbing & Heating for any plumbing work. He's super skilled and has awesome customer service."

"Just Rite Heating & Cooling installed our central air conditioner today. The team of five were on time, courteous, friendly and hard workers. They laid down runners to keep the interior of my house clean. The boss, Eric, explained how each part of the system components worked. Together we worked out the placement of the ceiling registers in each room. After the system was completely installed I was instructed on the how the new thermostat controlled both the old heating system and the new air conditioning system. Best of all the installation was completed in one day!"

Water Heaters questions, answered by experts

If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.

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.

Electric water heaters typically last 10 to 20 years, though proper maintenance can extend their lifespan. If your unit is over a decade old and showing signs of inefficiency—such as higher energy bills, frequent repairs, or leaks—replacement is a smart investment. Tankless models last over 20 years, which can make them a longer-lasting alternative to traditional tank water heaters.

Yes, a heat pump water heater can work in colder climates but it’s much more effective where it’s warm. The reason is that the heat pump needs ambient warmth in the air to compress. The less warmth, the more compression required, thus using more electricity and offsetting the energy-efficient benefits.

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.
