AC systems provide cool air to indoor areas, promoting comfort throughout the warmest seasons. If you experience problems with your unit, you might wonder whether an HVAC contractor should provide air conditioning repairs or a replacement. The following guide explores each option to help you determine which is best for your home. 

When to Repair 

Frequent cycling during the summer may cause fans and their bearings, which push cooled air into rooms, to overwork and wear out prematurely. Consistent operation can cause capacitors, which provide power to the compressor, blower, and fan motors, to become overheated and no longer hold a charge. In both cases, you might notice low or no cool airflow. Fortunately, these issues are minor, and an HVAC technician can usually repair or replace the components.

Pooling water around your AC unit may result from frozen coils. Dirt and dust accumulations on coils prevent warm air from making contact with them. Since coils contain refrigerant, they may become too cold and freeze. As they thaw, they may drip excess moisture into the condensate pan, causing it to overflow. Pooling water may also occur when the drain line leading away from the condensate pan becomes blocked. In either case, air conditioning repairs can remedy the problem, as a technician may thaw and clean the coils or clear line clogs.

When to Replace

As air conditioners age, they become less efficient, meaning they must use more energy to reach thermostat temperatures, elevating monthly utility bills. Additionally, an AC unit toward the end of its lifespan may no longer evenly cool indoor areas. Since air conditioning systems have a lifespan of about 15–20 years, upgrading yours once it nears this age can minimize energy expenses while promoting even cooling. 

Wear and tear on mechanical components, such as motor bearings and fans, may cause units to break down frequently. If you keep paying for the same minor repairs or a single repair expense amounts to over half the cost of a new system, replacing the unit might be more financially worthwhile.
