Family-owned since 2008
Started in 2008, out of Saucier, with a single truck, a tool bag, and a rule: answer every call, show up when we say we will, and do the job right the first time. Seventeen years later, that hasn't changed. What's changed is the size of the operation.
Today Keith's Heating & Air Conditioning runs eleven trucks across the MS Gulf Coast, employs a team of W-2 technicians (no subcontractors), and services roughly 3,000 calls a year from Gulfport to Hattiesburg. We're a Rheem Triple Diamond Dealer, an accolade we've held for seven years running that puts us in the top 2% of Rheem dealers nationwide. BBB A+ since 2018. Viewer's Choice Best HVAC 2022.
What makes Keith's different
Answered around the clock. 24/7, holidays included. When you call outside our normal hours, our AI answering service picks up first, and a real Keith's team member follows up as soon as possible. No phone tree, no endless hold music.
Same-day dispatch, no distance surcharge. Whether you're 5 minutes from our Saucier HQ or 55 miles away in Hattiesburg, you get the same rate and the same-day response.
W-2 employees, not subcontractors. Every tech in a Keith's uniform is on our payroll. Background checked, drug tested, uniformed, and trained on our standards. Not a random contractor with a Keith's magnet on their door.
10-year manufacturer parts warranty, 1-year labor. Every system we install carries a 10-year parts warranty through the manufacturer, plus 1 year of labor coverage from us. If it fails under warranty, we make it right.
Straight pricing. $80 flat diagnostic. No distance charge, no fuel surcharge. Service calls run $125 after 5 PM and on weekends, and we'll always tell you the rate before we roll a truck. If you approve the repair, the diagnostic applies.
Our promise
The Keith's Promise: if you're not 100% satisfied, we make it right. That's not a marketing line, it's how we've kept 4.9 stars across 1,609+ Google reviews since 2018. We'd rather fix a mistake than argue about it.
