You might encounter some problems after using your air conditioning system for years, especially during the hot and warm seasons. However, you don't need to be an experienced technician to know when something is amiss with your air conditioning system. If this comes after a long period of dormancy, it is easy to ignore the problem and continue running the system. But, as a responsible homeowner, it would help to learn some common AC problems that indicate urgent repairs.

1. Low or Leaking Refrigerant

Your air conditioner depends on the coolant to reduce heat and humidity from the indoor air. The coolant begins to leak if the refrigerant lines wear out and develop cracks. Low refrigerant levels could be why you have insufficient cool air circulation at home, high utility bills, low system performance, and frozen coils.

Replacing the coolant will not solve the issue. Therefore, the technician will inspect the extent of damage and fix any holes that cause the leaks.

2. Funky Smells Emanating From the Unit

Air conditioning vents are notorious for creating excellent breeding spots for mold growth. That could explain the strong, pungent smell that keeps getting stronger. Experts recommend routine duct cleaning, especially after a long, dormant period.

Schedule repair service immediately if you notice burning smells from your system when it's running. It could be an issue with its electrical connections. Additionally, gas smells are a clear sign of leaks that need immediate attention.

3. Frozen Evaporator Coils

One common symptom that signals you have frozen evaporator coils is when you don't receive cool air at home. When the coils are masked in dirt and debris build-up, airflow is limited and warm air fails to get to the coolant.

The refrigerant slowly becomes too cold that any moisture within its vicinity freezes. The coils follow suit and freeze, disrupting regular air conditioning cycles. The expert will need to defrost the coil, clean the system, and replace any faulty components to restore proper functioning.  

4. Leaky Vents

Ductwork facilitates cool airflow from the air conditioner into your home. If there are cracks and holes in the vent system, some of the air doesn't get to your home and ends up between walls. This could cause escalated energy bills and uneven air distribution. Therefore, you should let the technicians find the leaks to repair and solve the issue.

If you suspect any of these problems, contact an air conditioning contractor for help. They will inspect your air conditioning, fix the damaged parts, and advise you on ways to maintain it.
