Car Aircon Problem

[dr. d]

Mga boss pa advice nmn.. newbie here and sa car.. just bought a 1999 honda civic.. after 8mos ko na sya gamit then yung aircon nya may time na mahina buga kahit naka todo na.. tpos kinabukasan okay ulit.. then may time na babalik yung paghina ng buga to the point na magbaba na kami ng bintana.. per record nya january 2015 sya nalinis, napalitan receiver drier.. medyo takot ako dalhin sa gawaan at baka kung ano ano sabihin at palitan.. wala kasi ako idea.. so any advice sa possible problem and pricing just in case dadalhin ko nga sa gawaan. Salamat in advance.

i had similar problem with my non-honda car before.
it appears, the evaporator (orig had a leak, and we replaced it just a few days before) was not compatible with the rest of the aircon system.
tinipid ng gumawa, at yung mas murang unit ang linagay. ayun.. nag-yeyelo at hindi makadaan ang hangin.
so i had the evaporator replaced with the correct (much more expensive!) one, and i had my aircon back to as-new coldness.

but my suspicion is, your unit has low freon level, and it might be freezing up, blocking air flow, just like a home aircon lacking in freon, does..
determining freon level is easy and usually free.. they simply connect the gauge to the service nozzle.. have yours checked, sir.
