A-1 Guaranteed Heating & Air, Inc. had humble beginnings. The Vallejo-headquartered company that started in Krissy and Richard Hiteshew's garage now employs 21 people. The company has spent twelve years on the BBB Honor Roll and was voted Best Heating/Cooling Company for 5 years by the readers of the Vallejo Times Herald. Quite an achievement in any industry!

The company is aptly named. Since 1996 it's provided nothing but top-notch heating and cooling systems and service. They maintain a Trane Customer Satisfaction rating of over 98% - six points higher than the national average. A-1 Guaranteed's expert technicians make sure you get everything you need, without being sold unnecessary extras. They use only the best equipment, install it correctly, and keep it performing to its potential with regular maintenance. And no matter what duty they're performing, the A-1 Guaranteed techs exhibit professional, courteous, pleasant behavior. They clean up after themselves, follow up to make sure you're happy, and thank you for your business. It's the way companies used to treat customers, and the way A-1 Guaranteed still does.
