Summer is in full swing, and that means the temperatures are rising. If you’re like most people, you’re probably trying to stay cool by using your air conditioning unit. But what if your AC breaks down? Repairing an AC unit can be expensive – especially if it’s a major repair. In this blog post, we will discuss some of the most expensive AC repairs and how to avoid them!

Air Conditioner Compressor Repair

The compressor in your air conditioner is responsible for moving refrigerant through your system to remove heat and humidity. This is a time-consuming job, and if the compressor fails, it can be expensive to replace. Some air conditioners may still have a warranty that will cover the cost of a replacement compressor, but in most cases, you will be responsible for the expense. The average cost of a compressor replacement is $1800-$2800, so it is important to be aware of the potential cost before making the decision to replace your air conditioner. When the compressor fails, you may also need to replace other parts of your air conditioning system, so it is important to factor in the cost of these additional repairs when deciding whether or not to replace your air conditioner or repair the compressor. To avoid this have annual cleaning and regular maintenance by a professional.

AC Condenser Fan Motor Repair

The condenser fan motor in an air conditioner pulls air through the coils of the condensing unit. This repair is necessary when units sit idle for too long and the bearings and shaft in the air conditioner motor seize up or rust. To avoid this, have a spring inspection, clean the unit, and keep up with air filter replacements so the motor runs at full power. A seized or rusty condenser fan motor can cost anywhere from $600 to $1700 to repair. Therefore, it is important to take preventative measures to avoid this costly repair.

AC Evaporator Coil Replacement

The evaporator coils in an air conditioner play a vital role in the cooling process. As air passes over the coils, the refrigerant inside them absorbs heat, causing the air to cool. If the coils develop a leak, this can lead to reduced cooling efficiency and increased energy costs. In some cases, it may be possible to repair the coils, but in most cases, the entire coil must be replaced. Replacing an evaporator coil typically costs between $2,250 and $4,000. To avoid having to replace the evaporator coils, it is important to have them cleaned and serviced on an annual basis. This will help to ensure that they are free of dirt and debris and that they are properly charged with refrigerant. By having annual maintenance performed on your air conditioner, you can help to extend its life and avoid costly repairs.

AC Refrigerant Leak Repair

Air conditioners rely on a closed-loop system of refrigerant to function properly. If there is a leak in this system, it can cause the unit to lose its efficiency and efficacy. In some cases, a simple repair such as sealing a copper bend at the end of a coil can fix the problem. These repairs can be costly, averaging between $250 and $1700. However, refrigerant is essential to maintaining the proper function of an air conditioner. Leaks can be prevented with regular inspections, cleaning, and maintenance by a certified professional. By catching these potential problems early, you can avoid more extensive – and expensive – repairs down the road.


Although the most expensive AC repairs are often those that are least anticipated, there are steps you can take to avoid them.
