10 Reasons Your AC Is Running But Not Cooling – And How HVAC & Appliance Repair Guys Can Help

Hey there, Lake Oswego! Is your AC running, but you’re still feeling the heat? We know how frustrating it can be when your air conditioner seems to be doing its job, but your home just won’t cool down. Don’t sweat it—literally! There could be a number of reasons why your AC isn’t performing at its best, and we’re here to break them down for you in simple terms. Whether it’s a minor fix or something more serious, our team at HVAC & Appliance Repair Guys is ready to help you get back to cool comfort in no time.

1. Improper Thermostat Settings

First things first—let’s talk about your thermostat. Sometimes the issue is as simple as an incorrect setting. Make sure it’s set to “Cool” and not “Fan” or “Off.” If you’ve done that and things still aren’t cooling down, it could be a thermostat malfunction. In this case, it’s best to have a professional check if it’s misreading the temperature.

2. Faulty Thermostat

If your thermostat isn’t working as it should, it can mess up your whole system. It might be turning the AC on and off at the wrong times or misreading the room’s temperature. Professionals can determine if it’s time to replace or relocate the thermostat, especially if it’s in a drafty or sunny spot.

3. Dirty Air Filter

A clogged air filter can seriously limit the airflow in your system, making your AC work harder and cool less. If your filter’s dirty, it’s time to swap it out. And if you’re not sure how to keep up with filter changes, we’ve got your back with routine maintenance services to ensure your AC is always breathing easy.

4. Frozen Evaporator Coil

Ice on the evaporator coil can stop your system from cooling. This can happen if there’s a refrigerant issue or poor airflow due to a dirty filter. Instead of letting the problem grow into something bigger (and more expensive), let our technicians check it out and get it running smoothly again.

5. Damaged Evaporator or Condenser Coil

Your AC has two essential coils—evaporator and condenser—that help with cooling. Any damage here will stop the cooling process in its tracks. Whether it’s a repair or replacement, our team can handle the heavy lifting to get your system back on track.

6. Clogged Condenser Unit

That outdoor unit does a lot of work, but it can get clogged with leaves, dirt, or debris. When that happens, it struggles to do its job, leaving your home warm. We recommend calling in a pro to clean it up and ensure it’s running optimally.

7. Refrigerant Leak

A refrigerant leak isn’t just bad for your cooling—it’s potentially dangerous. Not enough refrigerant means your system can’t cool properly, and if left unchecked, it can damage your compressor. If you suspect a leak, reach out to us immediately to avoid bigger problems down the road.

8. Incorrectly Sized AC Unit

If your AC is too big or too small for your home, it won’t cool efficiently. An oversized unit can short cycle, while an undersized one can’t keep up on hot days. If you’re in the market for a new system, we’ll help you find the right size to keep your home comfortable year-round.

9. Leaky Ductwork

Leaking air ducts mean that cool air isn’t getting where it needs to go. You might feel warm air coming through the vents because the cool air is escaping into places like your attic. We can inspect your ductwork and seal any leaks to improve your AC’s performance.

10. Mechanical Problems

Sometimes the issue is with the mechanics. Here are a few common culprits:

  • Damaged fan blades
  • Worn-out motors
  • Loose or broken belts

If any of these parts are malfunctioning, your AC might be running, but it won’t be cooling. Our team is experienced in diagnosing and fixing mechanical problems, so you can count on us to get it right the first time.

It’s easy to take your air conditioning for granted—until it stops cooling when you need it most! If your AC is running but not keeping your Lake Oswego home cool, the problem could be one of the issues we mentioned above. Whether it’s a dirty filter, a refrigerant leak, or something more complex, HVAC & Appliance Repair Guys is here to help.
