When temperatures start climbing in Arizona, your air conditioner becomes one of the most important systems in your home. As a family-owned and operated HVAC Chandler company, we perform Air Conditioning Service every day and see many of the same issues causing breakdowns.
If you’ve ever searched for “Air Conditioner repair near me”, chances are your system stopped working during the hottest time of the year. The good news is that most major breakdowns can be prevented with routine inspections and maintenance.
Below are the top 7 components that commonly fail in an air conditioning system and what homeowners should watch for.
1. Evaporator Coil Corrosion (Rust)
One of the most common issues we see during Air Conditioning Service in Chandler is corrosion on the evaporator coil.
The evaporator coil absorbs heat from inside your home, but over time moisture and age can cause the coil to rust. Once corrosion starts, it can eventually lead to refrigerant leaks.
In the video above, our technician shows a system with a rusted evaporator coil and discusses how the age of the system can impact performance and reliability.
Signs of a failing evaporator coil:
- Reduced cooling performance
- Ice forming on the coil
- Refrigerant leaks
- Rust or corrosion visible on the coil
2. Capacitor Failure
Capacitors help start and run the motors in your air conditioning system. In the Arizona heat, capacitors are one of the most common components to fail.
Signs of capacitor problems:
- AC unit won’t start
- Humming noise from the outdoor unit
- System turning on and off frequently
This is a very common reason homeowners search for Air Conditioner repair near me during the summer.
3. Compressor Failure
The compressor is the heart of your air conditioning system. It circulates refrigerant throughout the system to remove heat from your home.
Compressor failure can occur due to:
- Electrical issues
- Overheating
- Age of the system
- Lack of maintenance
Unfortunately, compressor replacement is one of the more expensive AC repairs, which is why regular Air Conditioning Service is important.
4. Condenser Fan Motor Failure
The condenser fan motor helps remove heat from the outdoor unit. When it fails, the system can quickly overheat and stop cooling properly.
Common signs include:
- Loud noises from the outdoor unit
- The fan not spinning
- Warm air blowing inside the home
5. Refrigerant Leaks
Refrigerant is what allows your AC system to remove heat from the air. When leaks occur, the system loses efficiency and cooling power.
Signs of refrigerant leaks:
- AC running longer than normal
- Warm air coming from vents
- Ice on refrigerant lines
Leaks often occur due to coil corrosion, like the issue shown in our video.
6. Electrical Component Failure
Air conditioning systems rely on multiple electrical components, including contactors, relays, and wiring. Over time these parts can wear out or burn out.
Electrical issues can cause:
- AC not turning on
- System short cycling
- Tripped breakers
7. Clogged Drain Lines
Your air conditioner removes humidity from the air, which drains through a condensate line. When that line becomes clogged, it can cause water leaks and even shut down your system.
Common warning signs:
- Water around the indoor unit
- Musty smells
- AC shutting off unexpectedly
Routine Air Conditioning Service helps keep drain lines clear and working properly.
Why Routine Air Conditioning Service Matters
Regular inspections allow technicians to catch small issues before they become major problems.
At our family owned and operated HVAC Chandler company, our technicians check critical components like:
- Evaporator coils
- Capacitors
- Refrigerant levels
- Electrical connections
- Drain lines
This helps homeowners avoid unexpected breakdowns during the hottest months of the year.
