When winter temperatures drop and your furnace starts acting up, you need more than just a quick fix – you need a heating partner who understands both emergency repairs and the preventive care that keeps your family warm all season. At Air 911 Heating and Cooling LLC, we've spent years perfecting our approach to furnace service, combining rapid emergency response with maintenance programs that prevent those middle-of-the-night breakdowns.
When your furnace stops working on a cold winter night, every minute without heat feels like an eternity. Our repair process prioritizes both speed and safety, ensuring your heating is restored quickly without compromising your family's wellbeing.
We don't just guess at furnace problems – we use proven diagnostic procedures:
Through thousands of service calls, we've become experts at fixing:
Here's something most homeowners don't realize: a properly maintained furnace uses up to 30% less gas than a neglected one. We see this proven every winter when our maintenance customers report lower heating bills despite rising energy costs.
We go far beyond a simple filter change. Our maintenance service includes:
We understand that inviting someone into your home to work on equipment that could affect your family's safety requires trust. Here's why your neighbors choose us for their furnace service needs:
Every technician on our team receives extensive safety training beyond basic requirements. We're not just fixing furnaces – we're protecting families. This includes:
During every service call, whether repair or maintenance, we perform safety checks that many companies skip:
We've designed maintenance plans based on what actually benefits our customers:
We offer flexible maintenance plans designed to fit different budgets and needs. Contact us for details about our current plan options and how they can save you money while protecting your heating investment.
Our region's weather patterns create unique challenges for heating systems. The combination of humid falls, variable winters, and occasional ice storms means your furnace faces stresses that systems in more stable climates don't experience.
Chattanooga's high humidity doesn't stop affecting your HVAC system just because it's heating season. That moisture leads to:
We combat these issues through proper maintenance, including rust inhibitors and moisture control strategies that extend equipment life.
When temperatures fluctuate between 70°F one day and 30°F the next, your furnace works overtime. This cycling stress causes:
Once furnaces hit 15 years old, we start seeing predictable problems:
The heat exchanger is your furnace's most critical safety component. After 15-20 years of expansion and contraction, microscopic cracks can develop. We use specialized cameras to inspect for these dangerous cracks that could leak carbon monoxide into your home.
Older furnaces typically operate at 60-80% efficiency, while modern units achieve 95%+. We help you calculate when the energy savings of a new system outweigh repair costs. Often, the monthly savings pay for the new equipment.
Manufacturers typically stop making parts 20 years after a model's discontinued. We maintain relationships with parts suppliers to find components for older systems, but sometimes replacement becomes the only option.
Let us share some insider knowledge about furnace repairs that can save you money and keep you safer:
Your heat exchanger separates combustion gases from the air you breathe. When it fails, deadly carbon monoxide can enter your home. Here's what we've learned from inspecting thousands of heat exchangers:
When we find a cracked heat exchanger, replacement is the only safe option. However, on furnaces over 15 years old, the cost of heat exchanger replacement often exceeds 50% of a new furnace price. We'll help you evaluate whether repair or replacement makes more financial sense.
Today's furnaces use several ignition types, each with specific failure points:
These ceramic ignitors glow red-hot to light your burners. They're reliable but fragile:
More complex than hot surface ignitors, these control the entire ignition sequence:
Your blower motor works year-round for both heating and cooling. Common issues include:
When you hear squealing or grinding, bearings are failing:
Carbon monoxide is the silent killer – odorless, colorless, and deadly. Every winter, we respond to CO emergencies that could have been prevented through proper maintenance.
We can't overstate how much proper maintenance matters for furnace reliability and efficiency. Our service records show dramatic differences between maintained and neglected systems.
A dirty furnace wastes fuel through incomplete combustion. Our maintenance service includes:
We regularly see efficiency improvements of 15-20% after comprehensive maintenance. For a typical Chattanooga home spending $150/month on heating, that's $30 monthly savings – enough to pay for maintenance several times over.
Our maintenance data shows:
Your furnace plays a crucial role in winter indoor air quality. With homes sealed tight against cold weather, proper filtration and humidity control become essential.
Furnace heat removes moisture from your air, causing:
We install Aprilaire and Honeywell humidifiers that:

From our Chattanooga headquarters, we provide comprehensive furnace repair and maintenance services throughout the region, ensuring no family goes without heat.
During heating season, we position technicians strategically throughout our service area for faster emergency response. Our maintenance routes are organized efficiently, allowing us to offer neighborhood scheduling and group discounts.
Maintaining an A+ rating with the Better Business Bureau requires consistent excellence. This rating represents:
During winter heating season, we prioritize no-heat emergencies and typically respond within 2-3 hours. We maintain service vehicles throughout Chattanooga with common furnace parts stocked for faster repairs. Maintenance plan members receive priority scheduling that often cuts response time in half.
We recommend annual furnace maintenance, ideally in early fall before heating season begins. This timing allows us to identify and fix problems before you need heat. Older furnaces (15+ years) or those running frequently may benefit from bi-annual service to ensure reliability.
Our comprehensive maintenance includes safety inspections (carbon monoxide, heat exchanger), performance optimization (cleaning, adjustments), mechanical service (lubrication, electrical checks), and efficiency testing. You'll receive a detailed report showing exactly what we did and any recommendations for your system.
Yes, we service furnaces of all ages. While parts for 20+ year old units can be challenging to find, we maintain supplier relationships to source components. We'll honestly advise when repair costs approach replacement value, helping you make the most cost-effective decision.
Watch for unusual noises (banging, squealing, rattling), inconsistent heating, frequent cycling, yellow flames instead of blue, increased heating bills, strange odors, or visible rust/corrosion. Any of these symptoms warrant professional inspection to prevent larger problems.
Extremely dangerous. A cracked heat exchanger can leak carbon monoxide into your home, potentially causing illness or death. If we discover a crack, we'll show you the problem and explain why immediate replacement is necessary for your family's safety.
Yes, we offer several plan levels from basic annual service to comprehensive coverage including repairs. Plans include priority service, repair discounts, and other benefits that typically save more than the plan cost through prevented breakdowns and improved efficiency.
With proper maintenance, furnaces typically last 18-25 years. Without maintenance, expect 10-15 years. Factors affecting lifespan include usage patterns, maintenance frequency, installation quality, and local climate conditions. We'll help you determine when replacement makes sense.
Absolutely! Clogged filters restrict airflow, causing overheating, heat exchanger stress, blower motor strain, and efficiency loss. Check filters monthly and change when dirty. It's the simplest maintenance task with the biggest impact on system health and operating costs.
Yes, we service small commercial heating systems including rooftop units, unit heaters, and commercial furnaces. We offer maintenance contracts, emergency service, and energy efficiency consulting tailored to business needs. Our commercial techs understand the importance of minimizing business disruption.
Short cycling (frequent on/off) commonly results from oversized equipment, dirty filters, thermostat problems, blocked vents, or overheating from restricted airflow. This wastes energy and stresses components. Our technicians diagnose the root cause and provide appropriate solutions.
Often yes. Replacing both ensures matched system efficiency, single installation disruption, potential package discounts, synchronized warranties, and optimal performance. We'll evaluate your specific situation and provide honest recommendations based on equipment condition and your needs.
Beyond regular maintenance: programmable thermostats save 10-20%, sealing air leaks reduces loss, adding insulation improves retention, cleaning vents ensures airflow, and upgrading to high-efficiency equipment can cut costs by 30-40%. We provide energy audits to identify your best savings opportunities.
Yes, we provide 24/7 emergency heating service. While after-hours calls may include additional charges, we keep rates reasonable. Maintenance plan members often receive reduced or waived emergency fees. Your family's warmth and safety are always our priority.
We partner with Service Finance to offer flexible payment plans for repairs and replacements. Options include low monthly payments, same-as-cash terms, and quick approvals. This helps when unexpected repairs strain your budget or when upgrading to efficient equipment.
