Exploring the Top Issues With Aging AC Units

 

Aging air conditioners can run into a lot of problems. Below are several common issues.

Air conditioning units aren't built to last forever. Constant exposure to varying weather conditions, such as storms and humidity, eventually gets the better of them. Aside from the unit type and size, other factors such as frequency of use and unit maintenance will determine the longevity of an air conditioner. On average, AC units last about 8 to 14 years. Here are the problems associated with aging air conditioning units:

Wear and tear

Although regular maintenance is essential to keep the air conditioning unit working correctly, it will still break down eventually. Aside from exposure to weather conditions that affect the appliance, chemicals in the air can also enter the AC unit, corroding its electrical and mechanical components.

Increased energy bills

Wear and tear or damage can cause an air conditioner to operate less efficiently. Appliance issues can cause the unit to work harder and consume more energy, which will increase the energy bills.

Ice build-up

Ice can accumulate on the AC unit, primarily through heavy use. This build-up could be the result of a clogged air filter limiting airflow. But, if there is a significant amount of ice on the evaporator coils, it could arise from a refrigerant leak or a broken fan. These issues may be the result of an aging appliance.

Refrigerant leak

Aging refrigerant lines can leak refrigerant, which is harmful to the environment. If the air conditioning unit is low on refrigerant, it could be because there is a leak. Adding more coolant won't fix the problem, but an experienced technician can come in to seal the line. 

Electrical issues

As the AC unit gets older, it's more prone to electrical faults. Some of the most common issues that can cause this to happen are faulty electrical components, such as relays, capacitors, and corroded wiring. Improper maintenance can also lead to a fire in the unit.

Fan problems

The AC unit has two fans designed to cool the air coming from inside and outside the home. They both work by delivering air over the evaporator coils. These fans may cease to function properly due to various factors such as worn belts, dirt, and debris.

If there is restricted airflow due to a fan problem, it could lead to compressor damage, which would mean replacing the entire unit.

Leaking ducts

Over time, cracks and breaks in the ductwork that runs through the house's walls could become apparent. These breaks could be caused by the age of the materials used to seal the ducts, allowing air to escape. Also, prolonged closing of the vents can cause air pressure to build up, leading to more holes.

Keep a regular maintenance schedule

The AC unit's lifespan can be prolonged by sticking to a regular maintenance schedule. Setting one up with a certified technician can ensure that the unit runs more efficiently for longer.
