How to Repair an AC: A Simple Guide to Fixing Common Air Conditioning Problems
If you're dealing with a malfunctioning air conditioner in the middle of a hot day, it can be frustrating and uncomfortable. While professional help is often needed, there are some basic steps you can take to troubleshoot and learn how to repair an AC on your own. Knowing these simple fixes can save you time and money, especially if the problem is minor. However, for more complex issues, it’s always a good idea to contact professionals, like those at Heritage Air Services, to handle the repair safely and efficiently.
In this post, we’ll walk through some common problems and tips on how to repair an AC when things go wrong.
1. Check the Thermostat
Before diving into more complicated fixes, always start by checking your thermostat. Sometimes the simplest solution is the right one. If your AC isn’t working, ensure that the thermostat is set to "cool" and the temperature is set lower than the current room temperature. You should also check that the thermostat has working batteries, as dead batteries can prevent the unit from turning on.
By starting with the basics, you can potentially avoid unnecessary ac repair and get your system running again quickly.

2. Inspect the Air Filter
One of the most common causes for air conditioning issues is a dirty or clogged air filter. When your air filter becomes too dirty, it restricts airflow, causing your AC to work harder and reducing its efficiency. This can lead to poor cooling or even cause your system to shut down.
To repair an AC suffering from airflow problems, simply locate the air filter and check its condition. If it looks dirty or clogged, replace it with a new filter. This simple fix can significantly improve the performance of your air conditioning unit.
At Heritage Air Services, we recommend checking and replacing your air filter every 1-3 months, especially during peak cooling seasons.
3. Inspect the Circuit Breaker
If your air conditioning system isn't turning on at all, there could be an issue with your electrical supply. Head to your electrical panel and check if the breaker for the AC has tripped. If it has, reset it and try running the system again.
If the breaker continues to trip, it may indicate a more serious electrical issue within the AC system, and you should call for professional ac repair to prevent any further damage or safety hazards.
4. Clean the Outdoor Unit
Another common issue that can affect your air conditioner’s performance is dirt and debris around the outdoor unit. The outdoor condenser coil needs to be clean and clear for your system to function efficiently. If it’s clogged with dirt, leaves, or grass, the airflow will be restricted, and your AC will struggle to cool your home.
To repair an AC suffering from poor cooling, inspect the outdoor unit and gently clean any debris from around the unit. You can use a hose to carefully rinse the condenser coil, but avoid using high pressure, as it can damage the fins.
Regular cleaning of your outdoor unit can help extend the lifespan of your system and prevent the need for more serious air conditioning repair down the line.
5. Check for Refrigerant Leaks
If your AC is blowing warm air or taking longer than usual to cool your space, there could be a refrigerant leak. Refrigerant is essential to the cooling process, and without the proper amount, your AC can’t function correctly.
Refrigerant leaks are not something you should try to fix on your own. If you suspect a refrigerant leak, it’s important to call a professional air conditioning repair service like Heritage Air Services. A trained technician can diagnose the issue, repair the leak, and recharge your system with the proper amount of refrigerant.
6. Inspect the Condensate Drain Line
Air conditioning systems remove moisture from the air, and this moisture is usually drained through a pipe called the condensate drain line. If this line gets clogged with dirt, algae, or mold, it can cause water to back up into your AC unit, potentially leading to damage or water leaks in your home.
To repair an AC with a clogged drain line, try to locate the condensate drain and check for any visible blockages. You can use a wet/dry vacuum to remove the clog, or carefully flush the line with a mixture of water and vinegar.
Preventing clogs in the condensate drain line can save you from costly ac repair bills and keep your system running smoothly.

7. Check for Frozen Evaporator Coils
If your air conditioner is running but not cooling effectively, frozen evaporator coils might be the issue. These coils can freeze due to poor airflow, low refrigerant, or even running the AC on very low temperatures for extended periods.
To repair an AC with frozen coils, turn off the system and let the coils thaw completely. Once thawed, try running the system again. If the problem persists, it’s a good idea to call a professional technician for a more thorough inspection and repair.
When to Call a Professional
While these tips can help you troubleshoot and understand how to repair an AC on your own, there are times when it’s best to leave the job to the experts. If the problem involves electrical components, refrigerant, or a major mechanical issue, it’s always safer to call a licensed HVAC technician.
Heritage Air Services provides reliable and professional air conditioning repair services for all types of AC problems. With proper maintenance and care, your AC system can run efficiently for years, keeping you cool and comfortable when it matters most.
