When your system breaks, AC repair becomes a top concern. Homeowners in Surprise, AZ often confuse the air conditioner and the air handler. However, knowing the difference is key. Both components are critical to your HVAC system. Proper HVAC repair depends on understanding each part’s role. At E R Heating & Cooling, we’ve seen it all.

What Is an Air Handler?
An air handler is a large indoor unit. It looks similar to a furnace. Yet, it doesn’t burn fuel. Instead, it moves air through your ductwork. It houses the blower motor and evaporator coil. These work together to circulate cool or warm air throughout your home.
Air handlers are commonly used with heat pumps. If your system uses a heat pump, it likely has an air handler, not a furnace. The air handler does not cool the air. It pushes the air that has already been cooled.
What Is an Air Conditioner?
Your air conditioner is typically located outside. It contains a compressor and condenser coil. These parts release heat from your home to the outside air. The air conditioner works by removing heat, not creating coolness.
Once heat is extracted, refrigerant moves inside to the air handler. There, the air handler pushes cool air through your ducts. The two units must work together. If one breaks, your entire HVAC system suffers.
Key Differences Between the Two
Let’s break it down further:
- Location: Air handlers are inside. Air conditioners are outside.
- Function: Air handlers move air. Air conditioners remove heat.
- Connection: They depend on each other to cool your home.
Without a working air conditioner, your air handler can’t cool the air. Without a working air handler, cool air won’t reach your rooms.
Signs You Need AC Repair in Surprise, AZ
Phoenix summers are brutal. So are Surprise summers. If your AC fails, the heat becomes unbearable. Watch for these signs:
- Warm air is blowing from vents
- Weak airflow
- Strange noises or smells
- High energy bills
- Inconsistent room temperatures
If you notice these, call E R Heating & Cooling for fast AC repair. Our team understands both air handlers and air conditioners.
Can You Repair One Without the Other?
Yes and no. It depends on the issue. If your air handler motor fails, your air conditioner may still work. But air won’t circulate. If your air conditioner loses refrigerant, the air handler can’t push cool air.
Sometimes, only one component needs HVAC repair. Other times, both do. Only a licensed technician can determine the full scope.

When to Replace Instead of Repair
Sometimes AC repair isn’t enough. Systems over 10-12 years old often need replacement. Especially if repairs are frequent or costly.
Signs it’s time to replace both units:
- Multiple repairs in a year
- The system uses outdated R-22 refrigerant
- Your energy bills keep rising
- Poor indoor air quality
- HVAC system is too noisy
E R Heating & Cooling offers free consultations. We’ll assess whether repair or replacement makes more sense.
How Surprise Weather Affects Your System

Filters clog faster. Motors overheat. Coils collect debris. That’s why regular maintenance is vital. It prevents expensive HVAC repair later.
