Ac Problems

octexas · 2015-07-05T16:36:38+00:00

We knew the ac did not work and tried adding Freon. We checked and it had was full. We then made sure the air compressor was running and it was. Is there anything else it could be? The heater works and when we change it to cool it just blows air. We are really frustrated at this point and hiring someone is not an option. Thanks in advance.

Hi Jim,

Sounds like the heater core may be clogged. Check the warmth/lack of warmth of the heater inlet and outlet hoses close to the firewall connections. If the core is clogged, the outlet will be much cooler than the inlet. If it is clogged, have it backflushed to knock the debris out of the core tubes. If it is not clogged, try installing a 195 degree thermostat.
