I couldn’t be happier with Gault. There were no games played. Just a very fair priced, straight to the point estimate for new central a/c and furnace. Installed the following week. Everyone was great. Highly recommend!

They installed a new H/H furnace and A/C unit in my home and it has a noticeable difference already. The old unit was undersized and looked like some 8 year old installed it, the new equipment is first class. But now with properly sized ductwork the home is much more comfortable. You only get what you pay for.

We have our home and an apartment above our detached garage and have had both furnaces replaced in each. Great service. Great installations. Checkups were both great.  Would definitely recommend the company! All employees have been pleasant and helpful.

They did it all in one day and they were efficient. We were told one of the guys was new. There was a small leak in the system, but they came back the same day and fixed it. Their price was very competitive.

FAQ: Water heater installation in Grove City, PA

How do I know when my water heater needs to be replaced?

Most tank water heaters last 8 to 12 years. If yours is in that range and you are seeing rust-colored water, pooling around the base, or it just is not keeping up the way it used to, replacement is usually the smarter call. Frequent repairs on an aging unit are a good sign it is time.

What is the difference between a tank and a tankless water heater?

A tank unit stores 40 to 80 gallons of hot water and keeps it heated around the clock. A tankless unit heats water as you need it, so you are not paying to maintain a tank temperature when nobody is using it. Tankless units cost more upfront but typically last longer and cost less to run.

Is a tankless water heater installation right for my home?

It depends on your household's hot water habits and your existing gas or electrical setup. Tankless is a good fit for homes that run out of hot water regularly or want to lower operating costs, but the unit needs adequate gas line capacity or electrical service to perform correctly. We will look at your home and give you a straight answer.

How long does water heater installation take?

A tank replacement is usually done in two to four hours. Tankless installation takes longer if gas line work, venting changes, or electrical upgrades are part of the job. We will give you an accurate timeline before we start.

Do you pull permits for water heater installation in Grove City?

Yes. Pennsylvania requires a permit for water heater installation and we handle that as part of the job. Everything is installed to current code by licensed technicians.

What size water heater do I need?

For tank units, most two to three person households do well with 40 gallons. Families of four or more usually need 50 to 80. For tankless water heater installations, we size based on flow rate rather than storage volume. We make sure what we recommend actually fits how your household uses hot water.

Water heater installation and replacement in Grove City, PA

Gault Heating & Cooling has been installing and replacing water heaters for Grove City homeowners since 1955. We work with tank and tankless systems, size everything correctly for your home's actual demand, and back every installation with a 2-year guarantee. If you are not sure which type makes sense for you, we will walk you through it without the sales pitch.

Conventional water heater installation & replacement

Tank water heaters are still the most practical choice for most Grove City homes. They are straightforward to install, compatible with existing plumbing setups, and less expensive upfront. When one fails, we can usually have a replacement in the same day.

Water heater installation that is done right and permitted properly

We install gas and electric tank water heaters sized to your household, connect to existing supply and fuel lines, handle venting where needed, and pull the permit. Before we leave, we run through the installation with you so you know what you have got.

Water heater replacement, when repair no longer makes sense

If your tank is leaking, corroding, or just not producing reliable hot water anymore, replacement is usually the right call past the 8 to 10 year mark. We remove and dispose of the old unit and have the new one installed and running the same day in most cases.

Tankless water heater installation for Grove City homeowners who keep running out of hot water

Tankless water heaters heat water as you use it rather than storing it, which cuts out the standby energy loss of a tank unit. They take up less space, last longer, and you will not run out of hot water mid-shower. The tradeoff is a higher upfront cost and installation that sometimes requires gas line or venting work.

Tankless water heater installation sized and installed for your home's actual demand

Before we install, we assess your gas line capacity, venting setup, and actual hot water demand to make sure the unit we recommend can handle your home. We take care of any line or venting modifications as part of the job and test everything before we leave.

Switching from tank to a tankless water heater replacement

Whether you are replacing an existing tankless unit or making the switch from a tank system, we start with the same assessment. We check whether the current infrastructure is still appropriate, handle any upgrades needed, and install the new unit correctly. We will give you a clear picture of what is involved before anything starts.
