What your neighbors are saying about us

Patrick was very professional! I cannot recommend him highly enough, and whatever company he is working for. I very much liked their maintenance plan. He explained it very well and we purchased it. I highly recommend this plan, this company and this technician.

We absolutely love Hunters for all our electrical needs. We had originally called them out bc someone redoing our floors had burned up an outlet. Christopher was very knowledgeable and polite. He explained all recommendations that he had in a way that I understood. They are the only company I will use for all our electrical needs and upgrades.

I am very pleased with the service I've received from Hunter Service Group. Stacy was kind, respectful of my home, and professional. The install was performed in a timely fashion and I couldn't be more pleased. I will use Hunter Services for any future needs that I have within your scope! Thank you!

I highly recommend Hunter Service Group. We have recently worked with Noe Garcia and Tony Ruiz to help my in-laws find the right home generator for them to add some peace of mind if the power goes out. Installation should take place in the next few weeks. It has been a great experience so far.

How Whole House Generators Keep Your Home Powered

A whole house generator connects directly to your home’s electrical system and runs on natural gas or propane. When the power goes out, it detects the outage and turns on automatically within seconds, no manual setup, no running outside in a storm. Your AC, lights, refrigerator, and other essential systems stay on without interruption.

Unlike portable generators that only cover a few appliances at a time, a whole house generator powers everything in your home at once. It is always ready, always connected, and requires no action from you when an outage hits.

Signs You Need a Whole House Generator

A whole house generator is a smart investment for a wide range of San Antonio households. It may be the right fit if any of these apply to you:

Someone in your home depends on medical equipment that requires a continuous power supply.
You work from home and losing power means losing income.
Your neighborhood has experienced repeated or extended outages in recent years.
You want to protect your plumbing from freezing during a winter storm event.
You are tired of losing food every time the power goes out for more than a few hours.
You have a security system, sump pump, or other critical systems that need to stay active.

How San Antonio Weather Makes a Whole House Generator Essential

San Antonio’s climate puts homes through a lot. Summers are long, hot, and humid, and losing power during a heat wave is not just uncomfortable, it can be dangerous. A whole house generator keeps your AC running so indoor temperatures and humidity levels stay under control. In winter, it means your heating system stays on during freezing temperatures, protecting both your family and your pipes.

Without a backup power source, even a short outage can lead to spoiled food, uncomfortable temperatures, and potential damage to your home. A whole house generator removes all of that uncertainty.

Frequently Asked Questions

What is the difference between a whole house generator and a portable generator?

A whole house generator is permanently connected to your home and turns on automatically during an outage. A portable generator requires manual setup and only powers select appliances at a time.

How long can a whole house generator run during an outage?

Since whole house generators run on natural gas or propane, they can run as long as fuel is available, making them reliable during extended outages that last several days.

Will a whole house generator power my AC during a San Antonio summer outage?

Yes. A properly sized whole house generator will keep your AC running, which is especially important given San Antonio’s extreme summer heat and humidity.

How loud is a whole house generator?

Most modern whole house generators operate at a noise level similar to a central AC unit, making them much quieter than portable generators.

Does a whole house generator add value to my home?

Yes. Backup power is an increasingly sought-after feature for homebuyers in San Antonio, particularly after major storm events have highlighted how vulnerable the grid can be.
