Simple Steps Before You Call the Pros
If your air conditioner suddenly stops working in the middle of a Houston heatwave, your first instinct might be panic. But before calling in a technician, you might be wondering: How can I fix my AC by myself? While many AC repairs require a professional, there are a few DIY troubleshooting steps that can get your system back up and running—especially if the issue is minor.
1. Check Your Thermostat Settings
Before diving into your unit, start with the thermostat. Make sure it’s set to “cool” and that the temperature is set lower than the current room temp. If your system uses batteries, replace them.
For programmable thermostats or smart units that are glitching, a reset might solve the issue. Learn more on our guide: how to reset your thermostat.
2. Inspect Your Air Filter
A clogged air filter can drastically reduce your AC’s performance or stop it altogether. If your airflow is weak or your unit keeps turning off, check the filter and replace it if it’s dirty. This simple task can improve your system’s efficiency and even extend its lifespan.

3. Check the Circuit Breaker
If your AC won’t turn on at all, it might be a tripped breaker. Head to your breaker box and look for a switch labeled “AC” or “air conditioner.” If it’s flipped, switch it off and then back on again. This is especially common during high-demand months in areas like West University Place and River Oaks.
4. Clean Around the Outdoor Unit
If your outside condenser unit is covered in leaves, dirt, or debris, it may struggle to pull in air and cool your home. Turn off the unit and gently rinse the outside coil with a garden hose. For tougher grime, refer to our guide on how to clean evaporator coils.
5. Check for Ice Buildup
If your AC is blowing warm air or making odd noises, inspect the evaporator coils inside. Ice buildup can stop your system from functioning. Shut off the system and let it thaw for a few hours. While this won’t fix the root cause, it can temporarily restore cooling.

FAQs
Can you fix your AC yourself?
In some cases, yes. Simple issues like a dirty air filter, tripped breaker, or incorrect thermostat setting can often be fixed without professional help. If you’re asking, “How can I fix my AC by myself?”, start by checking your thermostat, changing the filter, and clearing debris around your outdoor unit. For more complex problems—like refrigerant leaks, electrical issues, or frozen coils—it’s best to call a licensed HVAC technician to avoid causing further damage.
Why is my AC not blowing cold air?
If your AC is running but not blowing cold air, it could be due to a clogged filter, low refrigerant levels, dirty coils, or a faulty thermostat. It’s also possible the evaporator coil is frozen. Start by changing the filter and checking your thermostat settings. If that doesn’t work, schedule an AC repair service to diagnose and resolve the issue quickly.
Can I do AC maintenance myself?
You can handle basic AC maintenance yourself—like replacing the air filter, rinsing off your outdoor unit, and making sure your thermostat is working properly. These DIY steps can improve efficiency and prevent breakdowns. However, full AC tune-ups—like checking refrigerant levels, tightening electrical connections, and inspecting internal components—should be done by a professional.
How do you cool a room with a broken AC?
If your AC breaks down during a hot Houston summer, you can cool a room temporarily by closing blinds, using fans to circulate air, and placing a bowl of ice in front of a fan for a DIY cooling effect. Avoid using heat-generating appliances like ovens. Then, schedule emergency AC service with Bellaire Air Conditioning to restore comfort fast.
Why is AC repair so expensive?
AC repair costs depend on the problem’s complexity, parts needed, and labor time. High-efficiency units or systems with older components may be more expensive to service. While minor repairs are usually affordable, major issues—like compressor or refrigerant problems—can cost more. That’s why regular AC maintenance is key to preventing expensive repairs down the line.
