Straight Talk from Your CasPro Technician
Let’s be real, your HVAC system works hard, especially when summer turns your attic into a sauna or winter makes your windows rattle. And even with good maintenance, things can go sideways. I’ve been fixing HVAC systems for years, and most calls we get boil down to a handful of common (and totally fixable) issues. Here’s what to watch for, plus how to stop small problems from becoming “why is my house 90 degrees?!” emergencies. Read on about the most common HVAC problems and what you can do about them.
1) The Filter You Forgot About
We get it, life’s busy. But that filter is clogged with dust and pet hair? It’s like making your system breathe through a straw. Poor airflow, higher bills, and even breakdowns can follow.
Do this: Swap it every 2–3 months. (Pro tip: Write the date on the filter frame so you remember.)
2) Thermostat Acting Possessed
If your air conditioner turns on and off randomly, or worse, does not turn on at all, your thermostat may need to be adjusted (or replaced).
Try this first: Replace the batteries, then double-check the settings. Is it still wonky? We’ll test it, no ghostbusting necessary.
3) Breaker Tripping (Again)
HVAC systems are heavy on energy, especially during heatwaves or cold snaps. If your breaker continues tripping, a filthy filter or an electrical gremlin might be the cause.
Quick fix: Start with a clean filter. If it doesn’t work, let us look into it; DIY electrical work rarely ends well.
4) Mystery Puddles Around Your Unit
Water where it shouldn’t be? Usually means your condensate drain is clogged with gunk. Left alone, you’re risking mold or water damage.
Don’t wait: A quick service call now beats a soggy floor (or worse) later.
5) AC Blowing Warm Air
If your vents feel more “lukewarm breeze” than “arctic blast,” you might have a refrigerant leak. (Other red flags: hissing sounds or ice on the coils.)
Heads up: Refrigerant isn’t a DIY fix, it’s tricky stuff. We’ll seal leaks and recharge it safely.
6) Strange Noises (The Bad Kind)
The banging, shrieking, or rattling isn’t your HVAC’s new music; it’s a call for help. Loose parts, failed motors, or worn-out components may be to fault.
Rule of thumb: If it sounds like a haunted appliance, call us before it quits entirely.
7) Coils Dressed in Dirt
Your system’s coils need to stay clean to absorb heat efficiently. When they’re coated in grime, your unit works overtime and your energy bill climbs.
Easy fix: We’ll clean them during a maintenance visit, like a spa day for your HVAC.
8) Weak or Uneven Airflow
If some rooms feel stuffy or vents barely whisper, you could have blocked ducts, a dying blower, or (you guessed it) yet another dirty filter.
Our move: We’ll trace the issue and get air moving right, in the room left behind.
