Air 911 Heating and Cooling LLC was founded in 2023 and operates out of 4295 Cromwell Rd in Chattanooga, TN. The company was started for a simple reason: too many homeowners were waiting days for a callback, paying for repairs they did not understand, or living with a system that nobody ever explained to them. We set out to do heating and cooling differently - with clear answers, fair pricing, and a team that shows up when it says it will.
We are a young company, but the people behind it are not new to the trade. Our technicians bring years of combined HVAC experience to every call, from routine tune-ups to full system replacements. That hands-on background shapes how we work: we diagnose carefully, explain what we find, and let you decide.
Our service philosophy is built around how families actually live. We offer same-day service during business hours, seven days a week, and our hours are Monday through Sunday, 7 AM to 5 PM. We quote honest, upfront pricing before any work begins, and we treat your home's comfort as something worth taking seriously. When budget is a concern, we can walk you through HVAC financing options or a maintenance plan that spreads the cost of upkeep across the year.
The crew behind Air 911 is what makes the difference on every job.
Every member of our field team is a NATE-certified technician, which means they have passed the nationally recognized industry exams covering installation, service, and safety. As an authorized Armstrong ProTeam Dealer, our technicians are factory-trained on the equipment we install, and that training does not stop once the certification is earned. We invest in ongoing education so the team stays current on new equipment, refrigerants, efficiency standards, and diagnostic tools.
Just as important as the technical skill is how our technicians carry themselves in your home. They arrive in uniform, explain the work clearly, lay out your options without pressure, and clean up before they leave. We know you are inviting us into your space, and we treat that as the privilege it is - professional, respectful, and straightforward from the first knock to the final walkthrough.
Whether the job is a quick repair or a multi-day installation, the same standards apply. Our team works on Armstrong, Rheem, Lennox, Trane, and Samsung systems, so no matter what is in your home, there is a good chance one of our technicians has serviced it before. When you have questions, you get answers in plain language, not industry jargon.
Credentials matter in this trade because HVAC work involves gas lines, electrical systems, and refrigerants that have to be handled safely. Air 911 holds the licenses and accreditations that prove we meet professional standards across the region.
We are licensed in three states - Tennessee (TN-53170), Alabama (AL-23182), and South Carolina (SC-117295) - and we carry full insurance and bonding for your protection. We are also an A+ BBB rated company, a NATE-certified team, and an authorized Armstrong ProTeam Dealer.
We service and install equipment from Armstrong, Rheem, Lennox, Trane, and Samsung, which lets us match the right system to your home and budget rather than pushing a single brand. For larger projects, we offer financing through Service Finance so the cost of a new system fits your monthly budget.

Alongside Chattanooga, we cover Red Bank, Signal Mountain, East Ridge, Hixson, Ooltewah, Soddy-Daisy, Middle Valley, Walden, Cleveland, Ringgold GA, and Knoxville.
