We often mention how regular HVAC inspections, cleanings, and tune-ups prevent larger, more expensive problems. But how expensive can an HVAC repair be? A maintenance plan is pretty affordable compared to some of the most expensive HVAC repairs. Let’s take a look to put things into perspective.

Evaporator Coil Replacement: Up to $6,000¹

The evaporator coil is one of the most common sources of a refrigerant leak. A leaking coil will struggle to absorb heat, and the system may be unable to cool your home. Repairing an evaporator coil usually isn’t an option because of its complex design. Finding the exact location of a leak is also a challenge. Therefore, the part must be replaced. Not doing so can lead to system failure, so you’d have to replace your HVAC system.

An evaporator coil leak can be prevented by having it cleaned regularly. A buildup of dirt and debris can cause it to overheat, corrode, and develop holes and cracks.

Compressor Replacement: Up to $2,500¹

The compressor allows the refrigerant to circulate and remove heat and humidity. Your air conditioner won’t work without it. The compressor is a sealed component that is often difficult to repair. But if an HVAC contractor can repair it, you might spend from $600 to $1,200, depending on the problem and your warranty.¹

Schedule annual maintenance, which includes cleaning the compressor, to reduce the risk of needing it repaired or replaced.

Refrigerant Leak Repair: Up to $1,500¹

If a refrigerant leak can be fixed, it’ll cost less than replacing the coil. The cost of a leak repair depends on the source of the problem. Changing a bad rubber seal is one of the least costly solutions. Performing a repair at a bend in the copper coil is a complex, time-consuming, and expensive task. Fix a leak quickly, as it can cause further problems in your AC system.

During your annual maintenance service, an HVAC technician should inspect and clean the refrigerant lines. They can also determine if any parts are deteriorating and perform preemptive repairs to avoid this HVAC repair.

Condenser Replacement: Up to $4,200²

An HVAC condenser is designed to collect or release heat. If it’s under warranty, condenser replacement can cost $300 to $1,200. You’ll pay your HVAC contractor’s labor fees. However, if it’s not under warranty, the job can cost $1,200 to $4,200. A professional will often recommend replacing an older unit if its compressor has failed.

To prevent or delay condenser failure, call a professional whenever you suspect a refrigerant leak or notice dirty coils, bent fins, or fan issues.

Condenser Fan Motor Repair/Replacement: Up to $1,500¹

The condenser fan pulls air through the coils. It is run by a motor containing bearings, a shaft, and other parts that can rust or seize up when motionless for a while. Dirt in the system can interfere with the fan motor. The fan can then run slowly, intermittently, or not at all. It may also make unusual noises.

The potential for fan motor issues is another reason to schedule a spring HVAC inspection and tune-up. A professional can properly clean the system. Also, change the air filter regularly to avoid contamination.

Air Handler Replacement: Up to $5,600²

Air handlers typically run flawlessly for 10 or more years. If the air handler is failing, less cool air may blow from a vent or the AC may emit a foul odor when you turn it on. The air handler contains an evaporator coil and a blower fan. It’s a large component of your HVAC system and you’ll have to pay for parts and installation when replacing it. Most professionals recommend replacing the condenser and air handler together.

Regular maintenance can protect the air handler. Change the filter regularly and have dirty/clogged coils cleaned to prevent issues.
