AC Acting Up? Here’s What to Check Before You Call for Repair
A busted AC can really screw up your day. But before you pick up the phone and call for a Rocklin air conditioning repair service, there are a few things you can check on your own.
Here’s a simple, down-to-earth checklist to walk through before calling in the pros.
✅ 1. Check the Thermostat First
We know it sounds obvious, but it happens all the time. Make sure your thermostat is:
- Set to “cool” mode
- Set to a temperature lower than the current room temperature
- Showing a live display (if it’s blank, it might just need new batteries)
Sometimes, the issue is just a bumped thermostat or dead batteries. Easy fix!
✅ 2. Make Sure the Breaker Didn’t Trip
If your AC isn’t turning on at all, it might not be a mechanical issue. Try testing your electrical with the following steps:
- Head to your circuit breaker panel and check if the breaker for the AC unit has tripped.
- If it has, reset it once. But if it trips again quickly, don’t force it. That’s when it’s time to call for professional help. Safety first, always.
✅ 3. Check the Air Filter
Dirty air filters can cause short cycling, overheating, and prevent cold air from blowing. The good news is that this is a pretty easy one to fix.
- Check your filter
- Pull out your filter and hold it up to the light. If you can’t see through it, it’s time for a replacement.
- Change Your Filter Regularly
- Most homeowners should replace their filters every 1 to 3 months, especially during peak summers.
This little habit helps your AC run more efficiently and keeps your indoor air cleaner.
✅ 4. Inspect the Outdoor Unit
An AC’s outdoor condenser unit plays an essential role in the cooling process. If it’s blocked by debris or foliage, you’ll notice a drop in performance.
Here’s how to inspect it:
Debris Check
- Make sure it’s clear of any debris that may be blocking, or too close to, the vents.
Fan Check & Sound
- Check that the fan is spinning (and that there’s no unusual noise coming from it!)
Clog Check
- Don’t open the unit up, but if it looks iced over or clogged with dirt, that’s a solid sign to call in a technician.
Pro Tip: Keep at least 2 feet of clearance around the whole outdoor unit year-round.
✅ 5. Look for Ice (Yup, Really)
Speaking of blockages, if your AC has ice build up you might be in trouble.
Here’s what to check:
- Check refrigerant lines and evaporator coil (usually behind the air filter panel) for ice buildup.
- If you see ice, turn off your AC right away and set the fan to “on” to help it thaw.
Ice buildup can point to airflow issues, low refrigerant, or a dirty coil.
✅ 6. Listen to the Noises
Is your AC suddenly louder than a lawn mower? Weird noises can tell you a lot.
- Grinding = possible motor issue
- Hissing = refrigerant leak
- Banging = loose or broken parts inside
If you hear something unusual, try to note when it happens (startup, while running, etc.). It’ll help the HVAC tech diagnose it faster.
✅ 7. Smell Something Funky?
Odd smells could be more than just a nuisance, they might be signs of real problems.
- Musty = mold or mildew in the system or ductwork
- Burning = electrical issue or overheating part
- Rotten eggs = gas leak (call your utility company immediately if this happens)
Don’t ignore unusual smells. Even if the AC still technically “works,” it’s better to get it checked out.
