Air Conditioner Repair Costs by Part

Faulty Circuit Breakers, Relays, or Fuses

When your AC unit starts having electrical issues, it's often due to faulty circuit breakers, relays, or fuses. These parts can be the main culprit behind the malfunction, leading to unexpected breakdowns. According to HomeGuide, the cost for these parts typically ranges from $75 to $300 (or CAD 102 to CAD 410), which includes installation fees. 
​
The source of the problem might also be traced back to the main panel. An HVAC contractor can inspect your system and determine whether a repair is necessary or if a full replacement is needed. Having experienced similar issues with my own air conditioner, I understand how important it is to address these problems promptly to avoid more extensive damage.

Freon Leak Fix

Dealing with a Freon leak in your air conditioner can be costly, with fixes ranging from $200 to $1,500 (CAD 273 to CAD 2,048). Leaks occur due to holes or corrosion on the coils where the refrigerant resides. It's important to address these issues promptly. Low refrigerant levels can prevent your unit from cooling the air properly. Regular maintenance can prevent further damage. When a leak is detected, ensure it's repaired and inspect the coils for additional issues.

Refrigerant Recharge

When it comes to air conditioner repair, one key part often needing attention is the refrigerant. The average cost for a recharge is typically between $100 and $600 (CAD 137 and 819), according to HomeGuide. An air conditioner's refrigerant level should never be too low. The process of having a professional refill it is known as a refrigerant recharge. The AC recharge cost essentially covers the refill, which requires specialized equipment and skills to perform correctly.

Thermostat Replacement

When it comes to air conditioner repairs, the thermostat is a key part. The cost to replace a thermostat can range from $75 to $575 (CAD 102 to CAD 785). Keeping it accurate is important for performance. Programmable thermostats can be off by up to five degrees, making your AC unit run too long or too short, needing repair.

​After an inspection, a technician will review their findings. If your current thermostat is an older model, consider an upgrade to a smart thermostat. These have an error rate of half a degree and offer benefits like improved energy efficiency, adjustable settings and preferences. Staying updated with technology ensures your home remains comfortable.

AC Compressor Replacement

When your air conditioner isn’t producing cool air, the AC compressor might be at fault. This part is the heart of the AC unit and is particularly important. If you turn on your unit and hear the motions but get no output, a repair might be needed. According to Bob Vila, replacing an AC compressor can cost between $800 and $2,800 (or CAD 1,092 to CAD 3,824).

​Sometimes it’s more cost-effective to replace the compressor or even the entire AC system. A technician can examine your unit, give you more information, and outline your options. You may hear the fans run, but without a working compressor, there will be no cold air output. Every part of the AC unit is important for it to operate correctly and keep your air cooled.

Condensing Components Repairs

When it comes to AC repairs, understanding the condensing unit's components is crucial. The fan and pump are integral parts that often require attention. The cost for these repairs can range from $100 to $700 USD (CAD 137 to CAD 956). Whether it's the fan giving out or the pump failing, knowing when to replace these parts can save you from more significant issues.

​You'll need to factor in the cost of the part itself and the service call. While some might feel confident using a screwdriver and following instructions for a DIY project, it's usually best to seek help from a professional. HVAC technicians can handle the repair or replacement and will test the unit to ensure it's as close to the manufacturer's settings as possible, helping to extend the lifespan of your unit.

Evaporator Coil Repair

Keeping your AC unit running smoothly is essential for maintaining a healthy home. One crucial component is the evaporator coil, which helps cool the indoor air by transforming refrigerant from a liquid to a gas. Over time, these coils can suffer from corrosion and bacterial growth, impacting your home's air quality.
​
Repairing or replacing the evaporator coil in a timely manner can prevent these issues, ensuring the cost of repair stays manageable. Regular maintenance helps to keep the evaporator coils clean and repaired, promoting better efficiency and extending the lifespan of your AC unit.
