When the Tennessee heat hits and your AC system starts acting up, you need a team that truly understands both the urgency of repairs and the value of preventive maintenance. Here at Air 911 Heating and Cooling LLC, we've built our reputation on treating your comfort as our emergency while also helping you avoid those emergencies through professional maintenance.
After years of keeping Chattanooga homes comfortable, we've learned that the best repair is the one you never need. That's why we offer comprehensive services that both fix immediate problems and prevent future ones.
We offer a full range of AC repair and maintenance services to keep your home comfortable year-round.
Our technicians don't just guess at problems – we use systematic testing to identify exactly what's wrong:
Through thousands of service calls across Chattanooga, we've seen it all:
Here's something most people don't realize: a well-maintained AC system uses up to 25% less energy than a neglected one. We've seen this proven time and again with our maintenance customers who consistently report lower utility bills.
We don't just change your filter and call it done. Our comprehensive maintenance covers:
We understand you have choices when it comes to AC service. Here's what sets us apart from the competition and why your neighbors keep calling us back:
Our licensing across Tennessee (TN-53170), Alabama (AL-23182), and South Carolina (SC-117295) means we meet the highest industry standards. This isn't just paperwork – it represents ongoing training, insurance requirements, and accountability that protects you.
As an Armstrong ProTeam Dealer, we receive regular factory training on the latest equipment and repair techniques. But we don't stop there – we're also certified to work on Rheem, Lennox, Trane, and virtually every other brand you'll find in Chattanooga homes.
Our unique climate creates specific challenges for air conditioning systems. The combination of high humidity, temperature swings, and long cooling seasons means your AC works harder here than in many other regions.
Chattanooga's humid climate creates problems you might not see in drier areas:
When humidity is high and airflow is restricted, your evaporator coil can literally freeze solid. We see this frequently when homeowners neglect filter changes or close too many vents. The ice blocks airflow completely, and running the system with a frozen coil can damage your compressor – the most expensive component to replace.
That musty smell coming from your vents? It's likely mold growing in your ductwork or on your evaporator coil. Our humid climate creates perfect conditions for biological growth, especially when systems cycle on and off frequently. Regular maintenance includes antimicrobial treatments to prevent this health hazard.
Your AC removes gallons of water from the air daily. When condensate drains clog with algae or debris, water backs up and triggers safety switches. We install overflow protection and treat drains to prevent these shutdowns that always seem to happen on the hottest days.
After sitting idle all winter, many AC systems develop problems that only show up when you need cooling. Capacitors weaken over the winter months, contacts corrode, and critters sometimes make homes in outdoor units. That's why we recommend spring maintenance before the first hot day.
When temperatures soar above 90°F, your AC runs almost continuously. This extreme operation exposes any weaknesses in the system. Worn components that work fine in mild weather often fail under peak summer loads. We see more compressor failures in July and August than any other time.
By autumn, your system has worked hard for months. Coils are dirty, filters are clogged, and efficiency has dropped significantly. Many homeowners don't realize they're paying 20-30% more to cool their homes by season's end due to neglected maintenance.
Let me share some insider knowledge about AC repairs that can save you money and frustration:
Refrigerant doesn't wear out or get used up – if you're low, you have a leak. Here's what we've learned from fixing thousands of leaks:
When we find a leak, we'll give you honest options. Small leaks in accessible locations are worth repairing. But when an evaporator coil develops multiple leaks, replacement often makes more sense than repeated repairs. We'll show you the math to help you decide.
If I had to pick the most common AC repair, it's capacitor replacement. These electrical components help motors start and run, but Chattanooga's heat shortens their life. We've found that proactive capacitor replacement during maintenance prevents about 60% of summer breakdowns.
Your compressor is the heart of your AC system and the most expensive component. Here's how we help protect this critical part:
I can't stress enough how much money proper maintenance saves. We track our customers' service records, and the difference between maintained and neglected systems is dramatic.
A dirty condenser coil makes your compressor work harder and run hotter. Just cleaning this one component can reduce energy use by 15%. Add in a clean evaporator coil, proper refrigerant charge, and good airflow, and you're looking at 20-25% energy savings.
Our maintenance customers average 75% fewer emergency repairs than non-maintained systems. When you factor in overtime charges, emergency fees, and the inconvenience of no cooling, maintenance pays for itself many times over.
Here's data from our service records:
We've designed our maintenance plans based on what actually helps our customers:
We offer multiple plan levels to fit different needs and budgets. Contact us to discuss which maintenance plan works best for your home and system.
Your air conditioner does more than cool – it's your primary defense against indoor air pollutants. Here in Chattanooga, with our high pollen counts and humidity, this role is crucial.
Every time your AC runs, it pulls air through the filter. But not all filters are created equal. We recommend MERV 8-11 filters for most homes – they catch allergens without restricting airflow. Higher MERV ratings can actually damage your system if it wasn't designed for them.
Proper humidity levels (30-50%) prevent mold growth and dust mite proliferation. Your AC removes moisture, but only when sized and maintained correctly. Oversized systems cool too quickly without adequate dehumidification – a common problem we fix.
Stagnant air breeds problems. Your AC system circulates and mixes air throughout your home, preventing stratification and reducing pollutant concentration. We often add ventilation controls to bring in fresh air during mild weather.
During maintenance or repairs, we can install several IAQ improvements:
These germicidal lights install in your air handler and kill mold, bacteria, and viruses. We've installed hundreds of Reme Halo and Air Scrubber systems with excellent results.
Far superior to standard filters, these use electrical charges to capture particles as small as viruses. Honeywell and Aprilaire models integrate seamlessly with your existing system.
Winter heating dries your air excessively. We install bypass and steam humidifiers that maintain healthy humidity levels automatically, reducing static, dry skin, and respiratory irritation.
Based in Chattanooga, we've built our reputation serving communities throughout the region with fast, reliable AC repair and maintenance services.
We strategically position our technicians throughout the service area during peak season, ensuring faster response times when you need emergency repairs. Our maintenance routes are organized by neighborhood, allowing us to offer group discounts and consistent technician assignments.
We've maintained our A+ rating with the Better Business Bureau by consistently delivering on our promises. This rating reflects:
During peak summer season, we typically respond to emergency calls within 2-4 hours. We maintain fully stocked service vehicles throughout our coverage area and prioritize no-cooling situations. Maintenance plan members receive priority scheduling that often cuts response time in half.
Repair fixes existing problems after they occur, while maintenance prevents problems before they happen. Think of it like your car – repairs fix breakdowns, but oil changes prevent engine failure. Regular maintenance costs far less than emergency repairs and extends equipment life significantly.
We recommend annual maintenance at minimum, ideally in early spring before cooling season. Older systems (10+ years) or those running frequently benefit from bi-annual service. Our Premium and Ultimate plans include multiple visits to keep your system in peak condition year-round.
Yes, we service all major brands including Armstrong, Rheem, Lennox, Trane, Carrier, Goodman, York, and many others. Our technicians receive ongoing training and have access to parts for virtually any system you might have.
Based on our service data, the top causes are: lack of maintenance (dirty coils, clogged filters), electrical component failure (especially capacitors), refrigerant leaks, and drainage problems. Most of these are preventable with regular maintenance.
Yes, we still service R-22 systems, though the refrigerant is expensive due to the phase-out. We'll discuss your options including repairing with R-22, retrofitting to a replacement refrigerant, or upgrading to a new R-410A system. We'll help you make the most cost-effective decision.
We use the 50% rule – if repair costs exceed 50% of replacement value, replacement usually makes more sense. We also consider age (systems over 15 years), repair frequency, and efficiency. We'll always give you honest recommendations based on your best interests.
Our comprehensive 21-point inspection covers electrical testing, refrigerant check, coil cleaning, drainage clearing, component lubrication, safety testing, and performance optimization. You'll receive a detailed report showing exactly what we did and any recommendations.
Yes, we provide 24/7 emergency service for our customers. While after-hours calls may include additional charges, we keep these reasonable. Maintenance plan members often receive reduced or waived after-hours fees as a benefit.
The best way is preventive maintenance – it's far cheaper than repairs. Also, change filters monthly, keep your outdoor unit clear, don't close too many vents, and address small issues before they become big problems. Our maintenance plans include repair discounts too.
First, check your thermostat settings and batteries. Then check circuit breakers for both indoor and outdoor units. Make sure your filter isn't completely clogged. If these don't help, call us. While waiting, close blinds and avoid heat-generating activities.
Absolutely! Clogged filters restrict airflow, causing your evaporator coil to freeze, your compressor to overheat, and your blower motor to fail prematurely. It's the easiest maintenance task with the biggest impact. We recommend checking monthly and changing when dirty.
Yes, we provide a 90-day labor warranty on all repairs, and parts come with manufacturer warranties ranging from 1-10 years. Our maintenance plan members receive extended labor warranties. We stand behind our work and respond quickly to any concerns.
Consider this: maintained systems use 15-25% less energy, need 75% fewer repairs, and last 5-7 years longer on average. A typical maintenance plan pays for itself many times over through energy savings and avoided repair costs. The math clearly favors maintenance.
We partner with Service Finance to offer flexible payment plans for repairs and maintenance agreements. Options include same-as-cash terms, low monthly payments, and quick approval processes. This helps when unexpected repairs strain your budget.
