Why It Matters

Why a Backup Generator Is Essential For Your Home & Business

Oklahoma storms and power outages happen without warning. A reliable generator keeps your home and business protected when the grid goes down.

Keep the Lights On

A standby generator restores power automatically within seconds of an outage — protecting your family’s comfort and safety around the clock.

Protect Your Home Systems

Prolonged outages damage sump pumps, refrigerators, HVAC systems, and medical equipment. A generator keeps critical systems on.

Extend Equipment Life

Proper installation and routine maintenance prevent wear, extend your generator’s lifespan, and protect your investment for years to come.

Prevent Costly Downtime

For businesses, power outages mean lost revenue and operations. A standby generator keeps you open and running no matter what.

Fuel Efficiency & Performance

Modern Generac systems are engineered for fuel efficiency, running only at the capacity needed and reducing operational costs during outages.

Peace of Mind Year-Round

With automatic operation and regular maintenance, your generator is always ready — giving you confidence through every Oklahoma storm season.

 Trustindex verifies that the original source of the review is Google. The team at A&T are the best in the business.  I use them for HVAC, plumbing and electric needs for both my home and my business.  I just had two ceiling fans installed at my home and their electricians went above and beyond.  Very thorough and professional.

 Trustindex verifies that the original source of the review is Google. Nick was amazing. He knew so much about the Lennox products that he was maintaining ( furnaces and a/c  units) He made some great recommendations and also showed us to get even better usage on our thermostats!  He was very personable, polite,  and efficient. I hope Nic can work with us on every occasion. Plus we decided to have him install surge protectors which will be installed this week. Looking forward to more preface of mind. We have always used A&T in this house, and always will.

 Trustindex verifies that the original source of the review is Google. Four stars instead of five only because the person who first answered our phone call and scheduled the visit said that they DID service floor furnaces, but the men who came said no, they didn't, but they did help us light out furnace, which was what we needed, and were very kind and helpful. I appreciate them!
