"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

Water heaters seldom ever burst, but when they do, you should know the warning signs to protect your home. The biggest sign that your water heater is about to burst is a sulfuric smell. If your home inexplicably smells like rotten eggs, then this could be an indication of a gas leak in your gas water heater. If gas leaks out of the unit, it could ignite and cause an explosion, so you should immediately shut off the gas and call a plumber near you to inspect your water heater.

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.

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.

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.

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.
