Top Reasons Your AC Isn’t Cooling 🛑
If your AC isn’t chilling the air, don’t panic. Here are the most common problems, plus what you can safely do before calling the pros at Ace Status Heating.
1. Dirty or Clogged Air Filters 🫧
Symptoms: Weak airflow, dust blowing, musty smell, AC runs but doesn’t cool.
Why it matters: Dirty filters restrict airflow, making your AC work harder and cool less.
What to try:
- Check your air filter (usually behind the return vent or inside the furnace/air handler).
- If it’s gray, dusty, or more than a month old, replace it with a new filter.
- Filters also protect indoor air quality—so swap them often for healthier air!
Pro tip: Set a reminder to check filters every 1-2 months, especially in summer.
2. Thermostat Settings & Battery Issues 🔋
Symptoms: AC won’t turn on, or is running but not cooling; thermostat screen is blank or flashing.
Quick checks:
- Make sure your thermostat is set to “Cool” and the temperature is lower than room temp.
- Replace the batteries if your thermostat uses them.
- Check programmable settings to ensure they’re not overriding your cool setting.
Smart tip: Sometimes, a thermostat can get bumped or the schedule can be off. Double-check before calling for AC Repair!
3. Tripped Circuit Breaker or Blown Fuse ⚡
Symptoms: AC unit won’t power on, nothing happens at the outdoor unit.
How to check:
- Go to your electrical panel and look for the breaker labeled “AC” or “Cooling.”
- If it’s tripped, turn it all the way off, then back on.
- If it keeps tripping, don’t reset repeatedly—this signals an electrical issue.
Call us: Persistent power loss means it’s time for emergency hvac help. Don’t risk electrical hazards!
4. Refrigerant Leaks or Low Refrigerant 🥶
Symptoms: AC blows warm air, hissing noises, ice on coils or lines, rising energy bills.
Why it matters: Refrigerant cools the air. Low levels mean your AC can’t do its job.
Safe troubleshooting:
- Look for water or ice near the indoor or outdoor unit.
- Listen for odd hissing sounds.
When to call Ace Status Heating:
- Only a licensed HVAC Repair pro can safely handle refrigerant leaks, recharge your system, and ensure EPA compliance.
5. Frozen Evaporator Coils or Air Handler ❄️
Symptoms: AC stops cooling, visible ice buildup, water leaks below air handler.
What you can do:
- Turn your thermostat to “Off” and switch the fan “On” to help thaw the coils.
- Check and replace dirty filters (a common cause).
When to call:
- If coils keep freezing or drainage issues return, call our emergency hvac team for a thorough diagnostic and safe repair.
6. Blocked Condenser Unit Outdoors 🌳
Symptoms: AC struggles in heat, unit runs constantly, minimal cooling.
What to try:
- Check the outdoor condenser unit (the big box outside).
- Remove leaves, grass, or debris from around the coils.
- Ensure at least 2 feet of open space around the unit for good airflow.
Never use a hose or pressure washer on coils—this can cause damage.
7. Duct Issues or Leaks 🌀
Symptoms: Certain rooms stay warm, weak airflow, high utility bills.
Possible DIY checks:
- Accessible ducts (like those in the attic) should be connected and sealed.
- Look for obvious gaps, but don’t try to fix major ductwork yourself.
Our team offers: Duct Cleaning, Air Balancing, and expert Duct Inspection as part of our HVAC Maintenance packages.
