When your air conditioner fails on a hot Tennessee afternoon, waiting days for help is not an option. Air 911 Heating and Cooling provides same-day emergency HVAC service to homeowners and businesses throughout the Chattanooga area. Our technicians offer priority same-day response during business hours, seven days a week, to restore your comfort as quickly as possible.

Emergency calls are handled with the same professionalism and quality workmanship we bring to every scheduled appointment.
Every Air 911 technician holds NATE certification - the HVAC industry's most respected independent credential. NATE (North American Technician Excellence) certification means our technicians have passed rigorous testing on real-world installation and service situations. You are not getting a self-taught handyman; you are getting a trained professional who understands equipment specifications, refrigerant handling, electrical safety, and system diagnostics at a level that directly protects your home and your investment. Combined with our State of Tennessee CMC mechanical license and local mechanical and gas licenses, Air 911 operates at the highest level of professional standards in the trade.
Air 911 Heating and Cooling holds an A+ rating with the Better Business Bureau - a reflection of our commitment to resolving customer concerns, operating transparently, and standing behind our work. As an authorized Armstrong ProTeam Dealer, we have earned direct access to Armstrong's full line of high-efficiency heating and cooling equipment, factory training resources, and manufacturer-backed warranty support. Armstrong ProTeam status is not automatic; it requires meeting Armstrong's standards for technical training, customer satisfaction, and business practices. When you choose Air 911, you are working with a company that meets those standards and takes that responsibility seriously.
Air 911 is licensed to perform HVAC work across three states: Tennessee (TN-53170), Alabama (AL-23182), and South Carolina (SC-117295). That multi-state licensing reflects our commitment to operating legally and professionally wherever our customers need us, not just in our home market of Chattanooga. It also means that customers with properties in multiple states - homeowners, property managers, and small business owners with locations across the Southeast - can rely on a single trusted contractor. Each license is maintained in good standing and our technicians are bonded and fully insured throughout every service area we cover.
When it comes to keeping your home or business comfortable, you deserve a company that offers complete solutions. Air 911 Heating and Cooling specializes in a full range of HVAC services to meet every need:

Expert AC service from diagnosis to installation - backed by manufacturer warranty coverage.
When your central air conditioner stops cooling effectively, the problem could be one of several common issues our technicians diagnose every day. Refrigerant leaks are among the most frequent causes of reduced cooling capacity - a system low on refrigerant cannot transfer heat efficiently, and simply adding more refrigerant without finding and fixing the leak is never the right answer. Our technicians locate the source of the leak, repair it, and recharge the system to the manufacturer's specification.
Capacitor failures are another common cause of AC breakdowns in Chattanooga's hot summers. A failed start or run capacitor can prevent the compressor or fan motors from starting at all. Frozen evaporator coils, often caused by restricted airflow or low refrigerant, are another issue we diagnose regularly. Thermostat problems - whether a faulty sensor, miscalibration, or wiring issue - can cause short cycling, temperature inconsistency, or a system that simply will not respond. Condenser problems, including dirty or damaged condenser coils and failing condenser fan motors, reduce the system's ability to release heat outdoors and drive up energy consumption.
Air 911 technicians carry common replacement parts on every service vehicle so that most AC repairs in Chattanooga can be completed in a single visit. Learn more about our AC repair services.
A new air conditioning system is one of the larger home investments a homeowner will make, and proper sizing is the most important factor in getting it right. Air 911 uses Manual J load calculations to determine the precise cooling capacity your home requires based on square footage, insulation levels, window area, orientation, and local climate data. An oversized system cools the space quickly but cycles off before removing humidity, leaving you with a clammy, uncomfortable home. An undersized system runs continuously, struggles to reach the set temperature on peak days, and wears out prematurely. Proper sizing, done by the numbers, is the foundation of a good installation.
We install and replace systems using current SEER2 ratings - the updated efficiency standard that replaced the original SEER metric beginning in 2023. Higher SEER2 ratings mean lower operating costs over the life of the system. We can help you compare equipment options across the efficiency range and identify any available rebates or incentives, including TVA EnergyRight rebates for qualifying equipment.
For homes without existing ductwork, or for additions and renovated spaces, we also install ductless mini-split systems and heat pumps that provide both heating and cooling from a single unit. Learn more about AC installation and replacement.
Annual air conditioning maintenance is the single most effective way to avoid unexpected breakdowns, preserve manufacturer warranty coverage, and keep your system running at its rated efficiency. Most equipment manufacturers require documented annual maintenance as a condition of their warranty - skipping that maintenance can void coverage on parts and labor when you need it most.
A spring AC tune-up from Air 911 covers the components that most commonly cause failures during the cooling season. Our technicians clean the evaporator and condenser coils, check refrigerant pressure, inspect electrical connections and contactors, test capacitors, verify thermostat calibration, clear the condensate drain, and assess overall system performance. This seasonal checklist catches developing problems before they become emergency repairs and ensures your system is operating at its designed efficiency before summer heat arrives.
As a member of the TVA EnergyRight Quality Contractor Network, Air 911 customers may qualify for a $50 rebate on AC tune-ups. Our maintenance plans also include priority scheduling, discounted repair rates, and seasonal reminders so you never miss a service interval. Learn more about our HVAC maintenance plans.

Modern HVAC equipment and smart controls can work together to meaningfully reduce the energy your home uses for heating and cooling - which typically accounts for the largest portion of a household's utility bills. Air 911 helps homeowners in Chattanooga and surrounding communities make informed decisions about efficiency upgrades that fit their budget and their home's actual needs.
Smart thermostats from brands like Honeywell, Ecobee, and Google Nest give homeowners precise control over their comfort schedules, remote access via smartphone, and usage reports that can identify where energy is being wasted. Many models learn your household's patterns automatically and adjust setpoints to reduce run time during unoccupied hours without sacrificing comfort when you are home. Air 911 installs and configures smart thermostats for compatible systems and ensures they are communicating correctly with your equipment for reliable, accurate operation.
On the equipment side, SEER2 ratings are the current standard for measuring central AC and heat pump efficiency. Higher-rated systems use less electricity to deliver the same amount of cooling - a meaningful difference in a Tennessee summer that can run five or six months. Energy Star certified equipment meets federal efficiency benchmarks and may qualify for utility rebates or tax credits depending on the program and timing.
As a member of the TVA EnergyRight Quality Contractor Network, Air 911 is positioned to help qualifying customers access available rebate programs on tune-ups and equipment upgrades. Contact us to ask what efficiency incentives may apply to your situation.

A central AC system only cools, requiring a separate furnace for heating. A heat pump provides both heating and cooling from one unit by reversing the refrigeration cycle. In Chattanooga's moderate climate, heat pumps operate efficiently for most of the year, lowering overall energy costs. For the coldest nights, many systems include auxiliary heat strips as backup. We'll assess your home and help you determine which option delivers the best comfort and value.
