To prevent ducts from becoming wet:
Moisture should not be present in ducts. Controlling moisture is the most effective way to prevent biological growth in air ducts.
Moisture can enter the duct system through leaks or if the system has been improperly installed or serviced. Research suggests that condensation (which occurs when a surface temperature is lower than the dew point temperature of the surrounding air) on or near cooling coils of air conditioning units is a major factor in moisture contamination of the system. The presence of condensation or high relative humidity is an important indicator of the potential for mold growth on any type of duct.
Controlling moisture can often be difficult.
Here are some steps you can take:
Penguin air practices a full service Preventative maintenance plan.
- Promptly and properly repair any leaks or water damage.
- Pay particular attention to cooling coils, which are designed to remove water from the air and can be a major source of moisture contamination of the system that can lead to mold growth.
- Make sure the condensate pan drains properly. The presence of substantial standing water and/or debris indicates a problem requiring immediate attention.
- Check any insulation near cooling coils for wet spots.
- Make sure ducts are properly sealed and insulated in all non-air-conditioned spaces (e.g., attics and crawl spaces). This will help to prevent moisture due to condensation from entering the system and is important to make the system work as intended. To prevent water condensation, the heating and cooling system must be properly insulated.
- If you are replacing your air conditioning system, make sure that the unit is the proper size and installed by Penguin Air licensed air conditioning contractor with pryde and experience ensuring a properly sized system for your needs and that all ducts are sealed at the joints will also increase energy efficiency. A unit that is too big will cycle on and off frequently, resulting in poor moisture removal, particularly in areas with high humidity. Also make sure that your new system is designed to manage condensation effectively.
Improper sizing air conditioning systems is a common problem:
- short runtimes.
- early compressor, fan failure
- results in a less efficient system
- higher energy bills.
- poor humidity control for cooling systems
- even as it is thought that a larger unit will keep a home cooler it is not so as the system short cycles it fails to remove the humidity from the home causing less comfort.
Good sealed ducts are important to keep an air conditioned home cool without upsizing your system because it is often the ducts improper seal and size that creates energy loss and gives the impresion of insuficient air flow.
