"I live in Conroe and have a tankless water heater. The technician joe Brawner came in and diagnosed it and found the issue at a reasonable cost and fixed it within the same day at a reasonable cost! Ask for joe when you call! He’s definitely cheaper than those bigger company’s!"

"Could not have been happier. Quick to respond and coordinate a service visit. Forrest was very informative and professional. Repair diagnosed and completed very fast. Got the water heater back up to speed and saved me a lot of money compared to a total replacement. They warranty their work for a year."

"Safe Air did an amazing job replacing the entire HVAC system in my house. They were quick and courteous of my house while doing the job. I had lost cold air the next day but they came out right away to find that there was a manufacturer defect in the coil. After a temporary fix it was working great again. They cam back out in the next couple days to replace the temporary part with the correct piece. I would absolutely hire these guys again and would recommend them to anyone who needs heating and cooling work done on their house."

"The yearly service works out to be $50 a month. We've had two water heaters replaced through them because of a fault in them. They're usually very responsive. I like that I can request the service online. The only thing is, I wish that there was a better avenue for emergency services. If something doesn't work right away usually it takes a couple of days to get someone out and sometimes you can't wait two days without water."

Water Heaters questions, answered by experts

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

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.

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.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
