Common Air Conditioning Problems and Solutions
No Cool Air
When your AC runs but doesn’t cool, it’s typically due to airflow restrictions, dirty filters, or refrigerant leaks. Start by inspecting your air filters—clogged filters are the most common cause. Replace them if they are dirty. Also, check that vents aren’t blocked by furniture or curtains.
Quick Fixes:
- Replace or clean filters monthly.
- Ensure all supply and return vents are open and unobstructed.
- If the issue persists, contact a technician to check refrigerant levels.

Strange Noises
Hearing unusual noises from your air conditioner, such as banging, buzzing, or clicking? These sounds often indicate loose components or electrical issues. A buzzing noise could suggest motor or fan problems, while clicking may point to a failing relay or capacitor.
Steps to Address Noises:
- Tighten loose screws or parts if accessible.
- Turn off the unit and inspect the fan blades for obstructions.
- Call a technician for persistent or electrical-related noises.

What to Do:
- Use a wet vacuum or pipe cleaner to clear the drain line.
- Turn off the AC to allow frozen coils to thaw.
- Ensure the unit is properly leveled to prevent drainage issues.
