Sizing

What size generator does your home need?

In Houston, air conditioning sets the size. Two AC systems and gas heat is a very different job from an all-electric house with a pool.

FAQ

Questions Houston homeowners ask

How much does a whole-house generator cost in Houston?

Most installed systems fall between about $10,000 and $25,000. Size, transfer switch, gas and electrical work, and permits decide where you land.

What size generator do I need?

It depends mostly on your AC systems, heat type and big electric appliances. Many Houston homes with two AC systems and gas heat land around 20 to 26 kW with load management. Try our calculator for your home.

Natural gas or propane?

If you have a gas meter, natural gas is usually the easy choice since you never refuel. Propane works well for homes without gas service.

How long does installation take?

The on-site work is often one to three days. Permits, HOA approval and any gas meter upgrade usually make the whole process several weeks.

Are you a generator dealer?

No. GeneratorsIn is an independent guide and free matching service. We don’t sell or install generators and aren’t an authorized dealer for any brand.

Does it cost anything to get matched?

No. It’s free for homeowners, with no obligation to hire anyone.
