AC Repairs: 10 Signs You Need Service Before Summer

Expect a Higher Level of Service

Air Quality - Ventilation and Duct inspection

As the Las Vegas heat starts creeping back in, the last thing you want is to be stuck with an AC unit that can’t handle the pressure. Trust us, the middle of a triple-digit summer day is not when you want to find out your AC needs repairs. Being proactive about AC maintenance is the key to staying cool and comfortable while avoiding costly breakdowns.

At Air Supply, we’re all about helping you keep your home cool without the stress. Here are the key signs that your AC needs some work before summer hits.

1. Weak or Warm Airflow

When you crank up the AC, you expect a rush of cold air to cool down your space quickly. If you’re experiencing weak airflow or warm air, that’s a clear sign something’s wrong. This could be due to a failing compressor, low refrigerant levels, or even clogged filters or ducts restricting airflow. Weak airflow means your system is working harder than it should, which can drive up your energy bills and lead to more serious damage over time.

2. Unusual Noises

Your AC isn’t supposed to be the life of the party. If you’re hearing banging, rattling, grinding, or squealing noises, it’s time to call in the pros. These sounds often signal loose parts, motor issues, or problems with the fan. Ignoring strange noises can lead to major breakdowns, so don’t wait until it’s too late.

3. Frequent Cycling On and Off

It’s normal for your AC to cycle on and off throughout the day, especially during peak heat. But if it’s happening too frequently or irregularly, that’s a red flag. Short cycling can be caused by a dirty air filter, thermostat issues, or even an oversized AC unit. Not only does this strain your system, but it also reduces energy efficiency, leading to higher utility bills.

4. Foul Odors

A musty smell when your AC kicks on could indicate mold or mildew buildup in the system or ductwork, especially if moisture has accumulated. A burning or electrical smell might signal overheating components or wiring issues—both of which need immediate attention for safety reasons. If your AC smells off, don’t ignore it. Air quality matters and strange odors often mean it’s time for a professional inspection.

5. High Humidity Levels Indoors

Las Vegas isn’t exactly known for high humidity, but if your indoor air feels more sticky than cool, your AC might not be doing its job. Part of your AC’s role is to control humidity levels. If it fails to keep moisture in check, there could be issues with the condenser, evaporator coils, or refrigerant levels.

6. Leaking or Excess Moisture Around the Unit

A little condensation around your AC unit is normal. But pools of water, active leaks, or signs of refrigerant leaks (like ice buildup on the coils) are not. Refrigerant leaks can pose health risks, and water leaks can cause property damage or even mold growth if left unchecked. If you notice leaks, call for AC repairs ASAP to prevent further damage and costly fixes.

7. Rising Energy Bills

Have your energy bills spiked without any major changes in your household’s usage? An inefficient AC could be the culprit. When components wear out or your system struggles to maintain the set temperature, it consumes more energy to compensate. If your energy costs are creeping up, even if your AC seems to be working fine, it’s worth getting a professional tune-up to identify hidden issues.

8. Inconsistent Temperatures

Are some rooms in your home ice-cold while others feel like a sauna? Uneven cooling is a sign your AC isn’t distributing air properly. This could be due to issues with the ductwork, thermostat problems, or even failing components inside the unit. Your home should have consistent comfort throughout—if not, it’s time to have your system checked.

9. Old Age of the Unit

If your AC is over 10-15 years old, it might be time to consider repairs or even a replacement. Older units are less energy-efficient, more prone to breakdowns, and often cost more to maintain over time. Regular maintenance can extend the life of your unit, but no AC lasts forever. Scheduling an inspection before summer hits can help determine if your system is still up to the task or if it’s time to upgrade.

10. Thermostat Issues

If your thermostat isn’t responding correctly or your home’s temperature doesn’t match the setting, it could be more than just a thermostat glitch. Faulty sensors, wiring issues, or communication problems between your AC unit and thermostat can cause inconsistent cooling. If adjusting the thermostat doesn’t improve comfort, it’s time for a professional inspection to get to the root of the problem.

Why Early AC Repairs Matter

Waiting until summer hits to address AC issues is a gamble—and not the fun Vegas kind. Early repairs mean:

  • Lower repair costs: Catching problems early often means cheaper, less extensive fixes.
  • Avoiding peak-season breakdowns: No one wants to be stuck without AC in 110-degree heat.
  • Better energy efficiency: A well-maintained unit runs more efficiently, saving you money.
  • Longer system lifespan: Regular care extends the life of your AC.
