HVAC Service Needs Unique for Each Local Environment
Inside humidity is Clean Air Green Envy Number One, no matter where you reside. That’s because of mold, fungus, and mildew grow and thrive amid high moisture. If humid conditions become severe, structural decay and health risks may appear in one year or less. U.S. Environmental Protection Agency stats reveal an ideal indoor air humidity of 30 to 50 percent. Excessive humidity easily results from the normal everyday activities like cooking, bathing, or doing laundry. This is especially so where ambient air is naturally humid in the first place.
Per World Data Center for Meteorology stats, humidity levels in Flagstaff reach an average of 68.8 percent by 5am each day. Winslow is a close second at 61.6 percent. Tucson isn’t far behind at 52.7 percent, followed by Phoenix and Yuma at 51 and 51.7 percent, respectively.
a. Deep Humidity Hold Keep Mold & Fungus Alive
If your house has a crawlspace, keep plastic covers on bare dirt to prevent soil moisture from being able to seep into its foundation. If stagnant water or wet soil is present, dry those areas with a fan before covering by plastic vapor barriers. Likewise, kitchen and bath ventilation fans lower indoor air humidity levels.
b. Air Duct Leaks Shut Keeps Dust Out
Inspect your clothes dryer exhaust vent to verify that it blows directly out. Also make sure it’s free of excess lint or other debris that create blockages. Clean dryer vent ducts at least once every 12 months and replace damaged metal parts that leak humid air back into your home. Do the same to HVAC ducts and plug gaps with carpenter’s putty.
c. Drain Pans & Maintain Fans
As noted above, A/C pans must be clean with no blockages, while fans blow directly out from blades free of dust or excess debris. Ask your service tech to check HVAC system humidity levels and advise if its size can remove air moisture efficiently. Also, request duct checks to identify air leakage repair needs and verify that airflow proceeds directly into all areas. An HVAC swab test can detect microbial growth. Maintain a log of test results to confirm your system is clean or discern signs that mean otherwise.
