Krissy & Richard Hiteshew with A-1 Guaranteed heating and air conditioning repair

Richard began A-1 Guaranteed Heating & Air, Inc. with his wife Krissy in 1996. His career in the HVAC trade began when he was 16 years old and got a job with his brothers at the same company they were at. He began as a shop boy in the warehouse. He also held other positions such as Service, Install and now owner. Krissy began her career in the HVAC when the business began. Having absolutely no previous experience in the field has provided an opportunity to learn something new every day. Prior to A-1 Guaranteed, she was an Admin Assistant, Billing Clerk and a Bookkeeper which has helped in the daily operation of the business. Richard and Krissy met while they were teenagers and have been happily married since 1989. When they began the business, they lived in a small 2 bedroom house and were pregnant with their 3rd child. They started in their garage. The company phone number was actually their home number that they used for the business and eventually had to get a personal number to keep the two separate. They have 4 children together, 3 of which are also in the business. A-1 Guaranteed became incorporated in April 2004.
