"As a small business owner, I strongly caution others against this HVAC/R company. In over 10 years, they?ve been the least trustworthy and poorest performing contractor I?ve worked with. We experienced repeated service issues, a 25% rate hike without notice, ignored emails, and unreturned quote requests. Worse, we were billed for work that wasn?t done?confirmed twice, including by a third-party inspection with photos. Even when confronted, they deflected and delayed for months. We had to hire another company. They also mis-sized a walk-in freezer due to bad measurements and blamed their supplier. When shown proof it was undersized, they argued with no solution. They later mismeasured again on a replacement bid. Their attitude throughout was defensive, unprofessional, and dismissive. If something goes wrong?and it likely will?they will not stand behind their work. Save yourself the frustration and look elsewhere."

Water Heaters questions, answered by experts

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.
