air conditioning not working right
Our air conditioning unit has been working great till this year. Had it serviced 2 weeks ago. Needed a new coil as the older one had a leak. Unit is only 6 years old. Today outside temp is 95. Unit in house set for 72. Its been blowing but staying at 74 all day and will not go down to 72. Vent temp is 67. Called 2 days to complain. Company said if its icing up there is a problem. But its not icing up. Outside temp now is 72. but the air cond is still running full out and house will not go below 73. What cold be wrong ? I pulled the filter out to give max air flow. Im wondering if the coil they installed is too small ??? although they said it was the right size. Full pressure will full freon (or whatever its called now). There is no way it should be running and not go down to the temperature in the house that it is outside. Any ideas ???
