Hi HVAC experts,
Something bothers me quite a bit. Hope some of you can give me some advices.
I had my new Carrier system installed last week: 24APA524A 2-ton, 15 seer, R410, new inside coil and plenum too, but keep the existing R22 lines.
The tech seemed not to be well tooled (broken tools, etc..) and did not flush the lines saying not necessary even when I did remind him several times.
He seemed did not evacuate the line properly as well, just run the pump for about 20 min before charging and did not even have a working gauge attached to the line other than the crude pump gauge.
The duck job is not very good either. I can feel some air leak around the plenum with my hands. But not seem to be too serious. Though I am sure my older system did not have any air leak.
The system is now working but no much better than the 10 year old system it replaced. In the hot day (97F and up) the system run non-stop and could only brings the inside temp to 78F-79F. Air temp at the register is around 68F-70F and 79F at the air intake.
I wonder if this has to do with the lines have not been flushed and evacuated properly? What should I do to fix this? Ask the tech to open the lines, re-flush and re-charge? Should I ask to replace the filter and compressor oil too?
I keep kicking myself for not stopping the tech when I knew he did not do the job correctly ...
Thank in advance for your advices.
