Jeff, glad to hear that things got sorted out.

One last issue: FILTERS. Think of them much like your oil/air filter in your car: Some trap the big stuff, some can even get the finer particles, but you will reach a certain point in each filter, where they will become too restrictive, and thus cause poor air flow. Use your best judgement when it comes to changing/cleaning your filters. Houses where there is a lot of "traffic", more dust, furry pets, etc., will need more routine maintenance than the elderly couple living alone.

Good luck.
Pete

air flow, air flow, AIR FLOW! (think of your air conditioning unit like a set of stock 5.0 heads....the more air that you can get through the "return system", the better.) make sure all return AND supply vents are clear/unobstructed.....


..as was stated earlier: ice on lineset (copper line) is a sign of poor airflow, or low freon charge.

duct work made from galvanized does not "collapse" unless it gets crushed by force. I dont buy that one. take zulu's advice, and pull the filter, let the unit "thaw out" (as the inside coil is probably a block of solid ice), and then check air flow again (run the fan in the "on" position. does it flow air now? if so, dial the temperature back down to "call for cooling", and wait a few minutes; some outdoor units have a "time delay", and will not immediately start up.

run it for 10 -15 minutes, and check the temp. coming out of the supply vents. -depending on the temp. inside & outside the home, you should be reading somewhere in the 45-55 degree range. check the out door unit: does it blow hot air from the fan area? re-check the copper lines, are they forming ice?

it sounds to me like a restrictive filter is the problem rather than a freon leak, since the filter change was the last operation done to the system.

pm me if you like.

keep us posted.
