Murphy's Law: It's about a million degrees outside, humidity levels are the highest they've been all year - and your air conditioning system freezes up. Frustrating, to say the least. Yet it's often an inevitable circumstance, and a fairly common one, too. Here's what you should do when faced with this frosty dilemma...
Simply put, shut it down. When A/C systems are frozen - and they continue to run - the potential for additional damage is increased. When a frozen system is turned off, the equipment will begin to thaw. If you're looking to expedite the thawing process, consider running the HVAC fan only (but be sure it ISN'T set to "cool!").
Check For Clogs & Line Leaks
The thawing process can take some time; While you wait, check and empty the A/C drain pan - and take a look at the condensate line, too. A clogged condensate line or drain can sometimes be the culprit.
Open Those Air Vents
Closed or blocked air vents can seriously hamper the airflow of an HVAC system, causing it to work harder than necessary. The harder a system works, the less efficient the operation. The end result? An eventual freeze-up. Be sure to open all operable air vents, and keep them clear of furniture or other bulky items.
Replace Your Dirty Filters
Much like obstructed air vents, a dirty HVAC air filter can cause an A/C system to work overtime. Dirty filters lessen the flow of air needed to cool a house, causing additional stress on a system. If you're looking for peak system performance, consider changing your air filter on a monthly basis.
Contact Your HVAC Technician
The solutions listed here are just the tip of the troubleshooting iceberg. A/C systems freeze up for a wide variety of reasons: low refrigerant, thermostat problems, a faulty fan - just to name a few. Issues like these usually require the talents of your trained HVAC technician.
