3 Problems You May Encounter With Your Garage Window AC
Posted on: 28 January 2021
Do you have a window air conditioner for your garage? Window ACs are great for small spaces that are not within the central cooling system's reach. They allow you to achieve comfortable temperatures during the hot season. However, just like any other ACs, window air conditioners are prone to faults along the way. Thus, note the following problems you may encounter when operating the unit.
Ice Build-Up on the AC
A window AC uses refrigerant to cool your garage. The refrigerant absorbs heat from the air, and as it passes through the condenser coils, the coils absorb the heat. Consequently, cool air from the surroundings is blown over the coils by the unit's fan. This cycle is crucial to the optimal operations of the window fan. If there's inadequate airflow due to clogs or fan failure, your coils may freeze.
Hot air contains moisture. The moisture gets removed as cool air blows over the condenser coils. With inadequate airflow due to dirt buildup, the coils get humid due to the warm indoor air. The moisture builds up over time and freezes. To prevent freezing, clean any dirt and debris on the unit. Also, check the fan to make sure it's working correctly.
Inadequate Cooling
Is your window unit no longer cooling your garage properly? Inadequate cooling may result from the following issues:
- Inadequate refrigerant
- Restricted airflow to the unit
As aforementioned, the refrigerant is paramount to the unit's performance. If there's a leak along the refrigerant line, there will be insufficient fluid. As a result, your window unit won't be able to absorb all the warm air from the garage.
Also, if you have a clogged fan or air filter, you may experience cooling problems. Dirt buildup in these components hinders airflow, causing your AC not to produce adequate cool air. Thus, replace worn filters and fans to boost the unit's performance.
No Cool Air
A window unit should blow cool air into the garage when you turn it on. If the unit is running, but there is no cool air, you may be dealing with system failure. This problem usually occurs due to a failed compressor unit. The compressor pressurizes the refrigerant to facilitate heat transfer. If it isn't working, you won't get even the slightest cold air in your garage.
A common cause of compressor failure is electrical problems. Surges in current due to voltage issues in your home can damage the compressor. Also, long-ignored problems such as low refrigerant and frozen coils can stress the compressor and lead to failure.
Window air conditioners have their share of problems. Luckily, most of these issues are fixable. Contact an HVAC contractor for AC repair services!
