Why Generator Installation Matters in Friendswood and Pearland
When Hurricane Beryl hit in July 2024, more than 2 million CenterPoint customers lost power, and some waited more than a week in summer heat.
A generator keeps the refrigerator cold, the air running, and medical equipment powered. The risk is in how it gets connected. A cord run from a portable generator into a dryer outlet can send power back onto the utility lines, putting line workers in danger. Generator installation done right keeps your house and the grid separated.
How Our Generator Installation Process Works
We start at your house, because no electrician can tell you what you need without looking first. We check your panel, your loads, and where a unit or inlet can go. Then we explain your options in plain language, with a clear estimate before any work begins. You decide.
Once you’re ready, we pull the permits, install the system by the code, and schedule the inspection. Before we leave, we test everything and walk you through startup and breaker management. The work is backed by our 100% Electrical Service Quality Guarantee.
Get a straight answer before you decide.
Whole House Standby Generator Installation
A whole house standby generator sits outside on a pad and runs on natural gas or propane. When the power drops, an automatic transfer switch disconnects your home from the grid and starts the generator. You don’t have to be home for it to work. We size it with a load calculation, so you know whether whole-home coverage or an essential-circuits setup makes more sense.
Standby units fit best when outages run long or when you want central air through a Houston summer outage. As a Generac dealer and certified installer, we supply and install the generator, so one company handles the equipment, the transfer switch, and the permits. We also handle generator repair and maintenance, so the unit starts when you need it.
Portable Generator Interlock Kit and Inlet Installation
If you already own a portable generator, an interlock kit is the safe, affordable way to connect it. We install an inlet outside and an interlock on your panel, which keeps the main breaker and the generator breaker from being on at the same time, so power can’t backfeed onto the lines.
Don’t have a generator yet? We can supply a Generac portable generator and install the interlock and inlet in the same visit.
Tri-fuel and inverter generators marketed as whole-house capable still need proper transfer equipment. Call us to learn more about portable generator interlock kit installation.

Is a Whole House Generator Worth It?
A whole house generator is worth it if your household can’t ride out a multi-day outage without power. Medical equipment, a home office, or older family members in the heat tip the answer toward standby. If your outages usually run a day or less, a portable generator with an interlock kit often covers what you need for much less. We’ll tell you which fits, even when the answer is the smaller job.
Generator or Battery Backup: Which Fits Your Home?
A home battery runs silently, needs no fuel, and can recharge from solar panels after a storm. The tradeoff is runtime: central air drains a battery fast. A standby generator on natural gas keeps running as long as the gas supply holds. Some homeowners use both, a battery for short outages and a generator for long ones. Either way, your electrical panel has to handle the connection, and we can tell you what it supports before you commit.
Whole House Surge Protection at the Panel
Power often comes back with a spike after a storm. A surge protector at your panel protects HVAC equipment, appliances, and electronics. It makes sense to add one during generator installation, since the work is already at the panel. Read more about whole house surge protection.
What Affects Generator Installation Cost
We price generator installation after we see the site. The main factors are:
- Generator size and how much of the home it covers
- Fuel type, and whether a gas line needs to be run or upsized
- Automatic transfer switch or interlock kit
- Panel capacity, and whether the panel needs work first
- Permits, inspection, and placement on your property

Generator Installation and Surge Protection FAQs
Can I connect a portable generator to my house without an interlock or transfer switch?
Can I connect a portable generator to my house without an interlock or transfer switch?
No. Without an interlock kit or transfer switch, a portable generator can backfeed power onto utility lines and endanger line workers. Residential Electrical Services installs the inlet and interlock so your generator powers your panel by the code.
Do I need a permit for generator installation in Pearland or Friendswood?
Do I need a permit for generator installation in Pearland or Friendswood?

How long does whole house generator installation take?

Most interlock kit installations take one day. A standby generator takes longer because of the pad, gas line, transfer switch, and inspection schedule.
Should a standby generator run on natural gas or propane?
Should a standby generator run on natural gas or propane?
Natural gas is the usual choice when your home already has gas service, because it doesn’t need refilling. Propane works where natural gas isn’t available.

What size generator do I need to run central air?
