A malfunctioning AC system in the summer can evoke panic. Homeowners may worry about whether or not an air conditioning repair will fix the issue. If they have an older system, they may also worry about whether they will need to get a new system. One of the most obvious signs that something is amiss is when an AC stops cooling. This phenomenon can be caused by a number of issues. The following points highlight reasons why an AC system may blow warm air.
No Power to the Condenser
The condenser is the outdoor portion of the AC system. If it loses power, it cannot cool. This is why one of the first things homeowners should do is check the circuit breaker for their AC system. If the breaker does not trip often, it is merely an inconvenience and a sign that the electrical system is working as intended. However, frequent breaker trips when using the air conditioning system are a sign of an AC repair issue. It can damage the system if repairs are not made.
Dirty or Frozen Condenser Coils
The condenser coils are located inside the condenser. They are prone to freezing, and dust or debris may also accumulate on them. The freezing phenomenon is triggered by unclean coils. This interferes with them being able to perform. Individuals who get routine maintenance for their AC systems usually do not have to worry about dirty coils. HVAC technicians clean them during air conditioning services. Another measure that homeowners can take to reduce the amount of dirt and debris on their coils is to invest in a cover for their condensers.
This is another issue that would be discovered during routine air conditioning services. Technicians inspect for leaks and make air conditioning repairs if needed. Sometimes the refrigerant may be low, which can also lead to warm air blowing. This requires refilling it to the correct level. This can only be done by a licensed HVAC professional.
An HVAC contractor is a good resource to use when an AC system is not cooling. They have a variety of air conditioning repair options they can implement after they make a diagnosis. If it is determined that the cost to repair is more than or in the same range as getting a new system, they will likely recommend an upgrade. This is often the case when critical parts such as air compressors need to be replaced. Air conditioning services that include a full replacement can give homeowners peace of mind that they have a working system under warranty.
