Learning About Commercial HVAC Systems

Hello, my name is Jacob. I would like to talk about proper installation and repair of the HVAC system in your commercial building. Full scale HVAC systems for commercial buildings require ongoing maintenance and repairs to keep every floor and room at a comfortable temperature. These temperature control systems also control the air quality in the building by sending the airflow through filter elements. My site will cover all aspects of the upkeep needed for these systems. I will also talk about the benefits of keeping your air quality and temperatures at desirable levels. Thanks for coming to visit my website.

Air Conditioning Ice Buildup: Common Causes

Isaiah Chapman

Central air conditioning systems depend on consistent, uninterrupted airflow through the unit for adequate cooling. When the air conditioner freezes, a layer of ice builds up on the coils and the interior surfaces. This not only disrupts airflow but can also lead to moisture problems, mold damage, and water damage as the ice thaws. Here's a look at some of the things that you need to understand about air conditioners freezing and the repairs that are required to address the problem.

Dirty Air Filter

The flow of air through the air conditioner plays an integral role in preventing ice buildup because it constantly cycles with enough volume to keep condensation from building up on the coil. When your air conditioning system's intake air filter is dirty, that restricts the airflow into the system. You may not have enough air moving through the unit to prevent ice from accumulating on the coils. Your air conditioning repair technician can not only replace the air filter but also clean the coils and the rest of the interior surfaces to remove dirt buildup that can also encourage ice accumulation.

Refrigerant Leaks

Central air conditioning is a closed system that depends on a precise level of refrigerant to keep the unit functioning as intended. When the refrigerant levels drop, typically because of a leak, that causes your air conditioner to work harder to achieve the same level of cooling. This excess effort and persistent cycling can cause the air conditioner to develop ice around the evaporator coil. You'll need to have an air conditioning repair technician test the refrigerant pressure to confirm the leak, locate and repair the source, then recharge your system to restore its proper cooling function.

Heavy Rainstorms

If you have ever noticed a sharp drop in temperature when rain storms come in, you'll understand the temperature shift that ultimately helps your air conditioner cool the air faster. Unfortunately, this also makes your air conditioner more likely to freeze up. Add the water that falls inside the case from the rain and you have a recipe for disaster when it comes to ice buildup. You can talk with your air conditioning repair technician about installing rain shields to help reduce the splash and rainfall effect in your air conditioning system.

These are just a few of the most common causes of ice accumulation in your air conditioning system. Talk with an air conditioning repair technician to troubleshoot your system's icing issues. For more information on air conditioning repair, contact a professional near you.
