When your air conditioner quits in the middle of a hot Washtenaw summer, your first instinct might be to pick up the phone and call a 24 hour AC service in Washtenaw. And while that’s exactly what professionals like us at Whitney Services are here for, the truth is that sometimes the problem is something you can fix in just a few minutes without needing a technician.
Before making that emergency call, it’s worth checking a few common trouble spots. A little troubleshooting can save you time, money, and stress while also helping you understand when it’s truly time to call in professional air conditioning services in Washtenaw.
Here’s a homeowner’s guide to what you should check first before reaching out for emergency AC service.
1. Make Sure the Thermostat Is Set Correctly
Your air conditioning system’s command center is your thermostat. If it’s set incorrectly, your AC won’t cool properly.
- First, confirm that the thermostat is switched to “Cool” mode and that the temperature is set lower than the current room temperature.
- Replace the batteries if the screen is blank. Many homeowners don’t realize that some thermostats still rely on batteries, and dead batteries are a common culprit when the system won’t turn on.
- Also, double-check the fan setting. The fan will run constantly if it is set to “On,” even when the cooling cycle is not in use. Switching it to “Auto” allows the fan to run only during cooling cycles, which is typically what you want.
Something as simple as correcting thermostat settings has saved countless Washtenaw homeowners from unnecessary service calls.
2. Check Your Air Filter and Airflow
A dirty air filter is one of the most frequent causes of inadequate cooling or weak airflow.
The airflow your system requires to operate effectively is restricted when a filter becomes clogged with dust, pet hair, or pollen. This can cause uneven cooling, higher energy bills, and even system breakdowns.
- Examine your filter and replace it if it appears gray or dirty.
- Most homeowners should change filters every 30–60 days, and more often if they have pets or live in a dusty environment.
- While you’re at it, check your house to make sure that no furniture, drapes, or rugs are blocking vents or return grilles.
Good airflow is essential for your system to do its job, and sometimes a new filter is all it takes to restore comfort.
3. Inspect the Circuit Breaker and Power Switches
If your AC won’t turn on at all, it could be an electrical issue rather than a system failure.
Look for a tripped breaker in the electrical panel of your house. If the breaker that powers your air conditioner is in the “off” or middle position, reset it and see if the system starts.
Also, look around your indoor air handler and outdoor condenser unit both usually have power switches nearby. These can sometimes be turned off by mistake during cleaning or yard work. Ensuring they’re in the “on” position may save you an unnecessary call for service.
4. Clear Around the Outdoor Unit
Your outdoor condenser unit needs room to breathe. If it’s surrounded by overgrown grass, bushes, or debris, airflow can be blocked, causing the system to overheat or cool inefficiently.
Walk outside and check the area around your AC unit. Trim back any plants within two feet of the unit and remove leaves, sticks, or dirt that may be clogging the fins.
Keeping your condenser clear not only prevents service interruptions but also extends the life of your equipment.
5. Look for Condensate or Drain Blockages
In addition to cooling the air, air conditioners also eliminate humidity. That moisture drains through a condensate line. If that line gets clogged, you might see water pooling around your indoor unit, or your system may shut down as a safety measure.
If you notice standing water in the drain pan or around the unit, the condensate line could be blocked by dirt or algae. In some cases, flushing the line with warm water or vinegar can solve the problem.
But if the issue keeps coming back, it’s best to call in professionals for a more thorough cleaning.
6. Listen for Unusual Sounds or Smells
Your senses are powerful tools when it comes to diagnosing AC problems.
- If you hear buzzing, banging, hissing, or grinding, your system may have an electrical issue, a loose part, or even a refrigerant leak.
- If you smell something musty, it could be mold growth inside the system. A burning odor could indicate an electrical fault, while a sour smell might point to drainage issues.
Any unusual sound or smell should be taken seriously, and in most cases, it’s time to call in air conditioning services in Washtenaw for a proper inspection.
7. Watch for Ice or Frozen Components
Another common issue is ice buildup on your evaporator coils or refrigerant lines. If you see frost or ice forming, it means the system isn’t getting proper airflow or that there may be a refrigerant leak.
Turn off your AC and allow it to thaw completely before turning it back on. If the freezing continues, it’s a sign that you need professional service. Ignoring it could eventually lead to more expensive and serious problems.
8. Monitor Energy Usage and Room Temperatures
Even though you continue to use your air conditioner, have you noticed that your energy bills are increasing? Or maybe one room feels like an icebox while another barely cools down?
Both are warning signs that your system isn’t running as efficiently as it should. It could be an airflow issue, ductwork leak, or a failing component.
By paying attention to your energy costs and comfort levels, you’ll know when something’s off before it becomes a complete breakdown.
9. Schedule Routine Maintenance (Pro Tip!)
Even if your system seems fine, preventive AC maintenance is the key to avoiding surprise breakdowns.
Every year or twice, a professional tune-up can:
- Improve energy efficiency
- Identify minor issues before they become major repairs.
- Keep your warranty valid
- Extend the overall life of your system
At Whitney Services, our technicians perform thorough inspections that include cleaning coils, checking refrigerant levels, tightening electrical connections, and testing system performance. One of the best investments you can make in the comfort of your home is routine maintenance.

Frequently Asked Questions
You should call immediately if your AC has completely stopped working in extreme heat, if you smell burning or electrical odors, if water is leaking heavily, or if you hear loud, unusual noises. These signs often mean a serious issue that shouldn’t wait until the next business day.
Check the thermostat first if your air conditioner isn’t working. Make sure it’s set to “Cool,” the temperature is set lower than the current room temperature, and the batteries are working. If the display is blank or the settings keep resetting, the thermostat may be the culprit.
Yes, it can. Your system may overheat or freeze as a result of restricted airflow caused by a clogged air filter. Changing your filter on a regular basis is one of the easiest ways to keep your air conditioner running smoothly.
This issue may be brought on by low refrigerant levels, dirty coils, blocked airflow, or electrical problems. If basic troubleshooting (like checking filters and thermostat settings) doesn’t fix it, it’s time to call a professional AC technician in Washtenaw for a full inspection.
Most experts recommend professional maintenance at least once a year, ideally in the spring before heavy summer use. In some cases, twice a year (spring and fall) is even better. Regular tune-ups extend your system’s life and prevent costly breakdowns.
