Why You Should Install a Generac Whole House Generator for Your Home

In Austin, unpredictable weather and power outages can disrupt your daily life. A Generac whole-house generator ensures your home stays powered, safe, and comfortable during unexpected blackouts. Here’s why home backup generators are a smart investment.

Automatic Power During Outages

Generac whole-house generators automatically detect power loss and restore electricity within seconds. Whether it’s a summer storm or a grid failure, you’ll never be left in the dark.

Power for Your Entire Home

Unlike portable generators, a Generac whole house generator powers your entire home, including critical appliances like refrigerators, HVAC systems, lights, and medical equipment. You’ll enjoy uninterrupted comfort and convenience no matter the circumstances.

Reliable During Severe Weather

Austin homeowners know how quickly the weather can turn severe. Generac generators run on natural gas or propane, making them dependable even when storms disrupt the electrical grid.

Frequently Asked Questions

THD stands for Total Harmonic Distortion and refers to the amount of distortion or interference in an electrical signal, often measured as a percentage. In the context of home generators, THD is important because high levels of THD can damage sensitive electronic equipment such as computers and televisions. To ensure safe and reliable operation, it is recommended to choose a generator with a THD level of less than 5%.

Air-cooled standby generators are a type of backup power generator that uses air to cool their engine, as opposed to liquid-cooled generators that use coolant and a radiator system. These generators are often used for residential or smaller commercial applications and are typically less expensive and easier to maintain than liquid-cooled generators. The engine in an air-cooled standby generator is typically smaller and has a lower power output compared to liquid-cooled generators. They are also more compact, making them a popular choice for residential use.

Mobile Link is a wireless monitoring system that connects your Generac standby generator to your smartphone, tablet, or computer. This allows you to monitor the status and performance of your generator remotely, receive notifications and alerts, and even control certain functions of the generator, such as starting or stopping it. It can also provide valuable information, such as the generator’s run time and maintenance schedule, to help ensure your generator is always ready to provide backup power.

200 SE (not CUL) stands for 200 amp service entrance, which means the generator is capable of handling a maximum electrical load of 200 amps. This is an important specification to consider when sizing a generator for your home or business, as it needs to be able to handle the total electrical demands of your property.

200 SE ATS (not CUL) refers to a 200-amp service entrance automatic transfer switch, which is a switching device that automatically transfers power from the utility to the generator when a power outage occurs. This ensures a seamless transition to backup power without any interruption to your electricity. The “not CUL” designation may mean that the generator has not been certified by the Canadian Standards Association (CSA), which indicates that the product meets applicable safety and performance standards.

Our Reviews

We switched from another plumbing and HVAC service to Stan's and we couldn't be more happy. Their prices are way more affordable, their personnel are much more knowledgeable, and they can get to you usually very quick - especially important if say your AC blows out in the middle of summer (which it did)! Highly recommend!

Aldarbert was very knowledgeable. He helped me to make the best decision for my Tesla and he installed it quickly. I was able to tested it out before he left, which worked perfectly as soon as him plug it in. I definitely recommend him and the company. Thanks!

Marva B.

Mr Robert Mendoza and Mr Daniel did an amazing Job replacing my evaporator coil which leaked with the new one. He took the time out to explain to me every detail he was doing as I asked questions. They both did a outstanding job. They made sure they put plastic down on my wooden floors as well

Larry D.

Showed up the next morning to check out the situation. Julian Rodriguez showed up later that afternoon with the new hot water heater. He explained everything he was doing during the process. Very thorough, polite & professional. Cleaned up the area he was working in and removed all the debris and old parts.

Aimee B.

“Stan’s has serviced our furnace and air conditioner for the past 15 years and was recommended by the former homeowner. They are knowledgeable and professional. As a longstanding company, the techs are prompt, friendly and trustworthy. I highly recommend them.”
