Airflow and Outdoor Unit Basics
4. Check the Air Filter
If your system has to work too hard to push air through a clogged filter, it won’t cool effectively.
Why it matters: Poor airflow reduces the air passing over the evaporator coils, making the air from the vents feel warmer. It can even cause your coils to freeze up, making things worse.
What to do: Locate the air filter, usually domiciled in the return duct or air handler. If it looks dirty or has been 90–120 days since you changed it, it’s time for a new one. A simple replacement could solve your problem.
5. Inspect the Outdoor Condenser Unit
The outdoor condenser releases the heat your AC pulls from your indoor air. The condenser will struggle to cool effectively when leaves, dirt, tall grass, or other debris obstruct airflow.
Clear away anything blocking the unit and trim back any vegetation within at least two feet around it. Make sure the fins are clean and unobstructed.
Electrical Components Matter, Too
6. Check the Circuit Breaker
Find your home’s main electrical panel and check the breakers labeled “AC,” “Air Conditioner,” “Condenser,” or “Air Handler.” A tripped breaker is often in the “Off” position or stuck halfway between “On” and “Off.” If tripped, reset it by turning it off and back on.
Important: If the breaker trips again immediately or repeatedly, leave it off and call a professional. This issue could point to an underlying electrical concern that needs expert attention.
When to Call a Trane Comfort Specialist
If none of the above steps restore the chill, your issue may need professional repair. Here are some common problems that require trained eyes and hands:
- Low Refrigerant Levels: A refrigerant leak will reduce your system’s cooling power. A professional HVAC technician must locate the leak and recharge the system properly.
- Dirty Coils: Even if you regularly replace filters, indoor and outdoor coils can gather grime over time. Dirty coils reduce your system’s ability to remove heat, lowering efficiency and performance.
- Compressor Issues: The compressor is the heart of your system. If it malfunctions, the entire cooling cycle is compromised. A professional HVAC technician should diagnose, repair, or replace a compressor.
- Leaky or Disconnected Ductwork: Damaged or disconnected ducts could cause inefficiencies and loss of treated indoor air. A technician can inspect and seal your ductwork.
