5 Things to Focus on When Inspecting an AC Condenser

If you are inspecting an AC condenser, there are things you should focus on whether it's the first time you are doing it or its part of your regular inspections. Here are some of those things:

Location of the Unit

If this is the first time you are inspecting the unit, then you should examine the location of the condenser unit since its location influences its efficiency. Ideally, the unit should be located in an area that ensures maximum air circulation. For example, a condenser unit that is located too close to a wall or fence may suffer from impaired air circulation, and the issue should be rectified.

Debris Accumulation

You also need to check if your condenser unit is covered in dust since debris accumulation may also affect the operation of the condenser. Windblown debris such as leaves, grass, flowers, dirt, and others will block airflow over the condenser fins and reduce heat transfer between the condenser and the outside air.

Physical Condition of the Fan

Examine the condenser fan for signs of physical damages, which is rare, but possible. The fan blades are designed in such a way that they provide maximum air circulation, which will be hampered if they are bent out of shape. Such damage may occur, for example, if the fan blades are struck by flying debris such as pebbles.

Physical Condition of the Fins

The condenser fins are more delicate than the condenser fan blades, which mean the former are more susceptible to physical damage. This is why you need to be careful when cleaning the condenser because you might damage the fins. Damage to the fins may also occur if they are struck by flying debris from lawnmowers. Such damages reduce the surface area of the condenser exposed to the outside air, which also reduces the efficiency of heat exchange.

Signs of Rust

Lastly, you should also examine the condenser unit for signs of rust. A little rust on the condenser unit is not a cause for alarm, but rust accumulation may herald serious problems. If you don't prevent or get rid of the rust, it will accumulate on the condenser, corrode it, and deteriorate or even create holes on the coils. Not only that, but too much rust accumulation also insulates the coils and interferes with heat transfer.

Apart from your DIY inspections, you should also get regular HVAC services not only for the condenser but also for the entire AC system. Also, don't forget to engage a professional technician if your DIY inspection reveals a concern.
