Your air conditioner works hard to keep your home cool and comfortable — especially during the hot and humid summers in Chattanooga TN. But like any machine, it’s bound to run into problems from time to time. Whether it’s a clogged filter or a faulty thermostat, knowing when to call for air conditioner repair in Chattanooga TN can save you from bigger, costlier issues down the road.
At Metro Plumbing, Heating and Air, our certified technicians are trained to identify and fix the most common air conditioning problems efficiently and affordably. Here are seven situations where it’s smart to call the pros.
1. Clogged Drains or Filters
Clogged air filters are one of the most common issues with A/C systems. They reduce airflow, circulate dirty air, and force your system to work harder, which increases energy costs. Clogged drains, on the other hand, can cause water to overflow from the condensate pan — leading to mold growth and even water damage to ceilings or walls. While replacing a filter might be easy, persistent clogs are best handled by professionals to ensure there’s no underlying damage.
2. Low or Leaking Refrigerant
Refrigerant is the chemical that cools the air inside your home. If it’s low or leaking, your system won’t be able to remove heat effectively — resulting in warm air blowing from vents. Recharging refrigerant and sealing leaks requires proper tools and EPA-certified handling. Call a licensed technician to diagnose and repair refrigerant issues correctly.
3. Frozen or Dirty Coils
The evaporator coil absorbs heat, while the condenser coil releases it. Both can become dirty or freeze over if there’s restricted airflow or too much dirt buildup. A frozen evaporator coil won’t allow your system to function properly, and a dirty condenser coil can cause the unit to overheat. If you’ve noticed reduced cooling power, unusual noises, or ice buildup, it’s time for professional coil cleaning and inspection.
4. Malfunctioning Fans
Your A/C uses fans to circulate air throughout your home. If the fans stop working due to a faulty motor, worn belts, or lack of lubrication, your system may overheat or fail entirely. You might also notice your system running nonstop or cycling erratically. A Metro Plumbing, Heating and Air technician can replace damaged components, restore fan function, and prevent damage to the compressor — the most expensive part to replace.
5. Leaking or Damaged Ductwork
If your central air conditioning system is struggling to cool your home evenly, the problem might lie in the ductwork. Over time, ducts can become leaky due to aging materials, pests, or physical damage. This results in cooled air escaping behind walls or into the attic, driving up your utility bills and reducing comfort. Our team can detect, seal, or replace faulty ducts to restore system performance.
6. Thermostat Issues
The thermostat is the brain of your HVAC system. If it’s faulty or miscalibrated, your A/C may cycle too often, not respond to settings, or run inefficiently. Sometimes a simple recalibration can fix the problem, but other times you may need a repair or upgrade to a smart thermostat. Metro’s experts can diagnose and resolve thermostat issues and help you choose a better system if needed.
7. Electrical or Wiring Problems
Wiring problems can be dangerous and should never be ignored. If your system frequently trips the circuit breaker or doesn’t turn on at all, faulty electrical connections may be to blame. These issues can lead to overheating, component failure, or even electrical fires. Only a licensed technician should perform electrical diagnostics and repairs to keep your system safe and code-compliant.
