Hot water is essential to your home comfort and the experts at Johnson Heating and AC are here to help make sure you don’t ever have to do without.

We are experts at traditional systems like storage tank hot water heaters, but we also install and service systems like tankless and heat pump hot water heaters.

We’ll Help You Properly Size Your Hot Water Heater

A lot of reasons why we get calls about hot water heaters in the first place is because at initial installation a homeowner’s hot water heater was not properly sized.

Typically, someone calls for water heater repair or replacement, however, we find once we get there that the malfunction, breakdown or need for repair is due to having a hot water heater that was never the right size for the home.

When you work with us right from the beginning, this will never be an issue because we take the time to size every single hot water heater we install or replace. And sizing goes for all hot water heaters, not just storage tank water heaters. Tankless units and heat pump hot water heaters also need to be properly sized, and we can help with these, too.

When Is It Time to Call for Water Heater Repair?

Many homeowners wait until their hot water heaters breakdown completely before calling for repair help. Some aren’t aware of the signs and others aren’t sure if there’s really a problem. Waiting for a complete breakdown of your hot water heater can make for a more costly repair bill, so here are some signs to stay aware of to get ahead of water heater repair in your home:

Strange noises – hot water heaters are not noisy appliances. At most you should hear a burner being ignited. If you are hearing more than this, it’s time to call for an expert.

Tepid water – there are a few reasons why your hot water heater is generating only tepid water and not hot water. Give our experts a call so we can diagnose and repair the issue.

Odors – smells should never emit from the unit itself, and if you are experiencing a rotten egg smell coming specifically from your hot water, you’ll need a professional to flush out your hot water heater.

When most people think of hot water heaters, they think of a storage tank type. Today’s tank hot water heaters are the most efficient yet, as new regulations and better design have recently come into effect. We specialize in gas and electric storage tank hot water heaters, and can help you with installation, repair, replacement or annual maintenance.

Tankless hot water heaters have become very popular among homeowners, but knowing whether or not a tankless unit is a good fit for your home is best decided with a trained expert. If you do decide to move forward with installation, make sure it is with a pro who knows how to correctly install these types of units. We can also make sure your existing tankless system works as needed with excellent repair and maintenance services.
