Vallejo, CA  March 31, 2021 – Krissy Hiteshew, co-owner and manager of A-1 Guaranteed Heating & Air in Vallejo, was recently named one of Daily Republic’s Women of Influence for 2021.

Hiteshew and her husband, Richard, started the business from their garage in 1996, which has since grown to be one of the top HVAC service providers in the area. In fact, A-1 Guaranteed Heating & Air was just named The Best Heating and Air Conditioning Company in the Times-Herald’sBest of 2020” awards.

Hiteshew says her goal is “to have happy customers that we have made more comfortable in their homes or even to have changed their health by improving their air quality.” She explains that her industry is one that is very gratifying, and the A-1 Guaranteed team is heavily involved in giving back to the community. She hopes one day to retire from the company and volunteer more of her time to giving back to those in the area. She hopes that people will continue to depend on her to help when needed, whether it be physically or financially.
