Ok, I want to apologize first, as this may be sort of long. I moved into my bi-level home 3 summers ago. First summer, a/c cooled perfectly without any problems. This year, I have notived that the a/c runs all day long, however, the temperature inside the home will not drop below 76. Cold air comes out of all the vents in the home. All vents are open. I had a tech. come out to take a look. He checked pressures, etc., and told me that my orifice was clogged because my compressor was starting to fail. He told me that when compressors start to go, oil and metal shards will break up and get into the lines. He stated that I needed a new outside unit, and told me he would flush the lines out with nitrogen, and pull a vacuum to suck anything out.
When he did this work, he showed me metal shards that were in the orifice. However, when he flushed the lines, no oil build-up or anything else came out. He also installed a new filter dryer on the liquid line. He informed me that everything would work well now. I am still having the same problem. A/c runs all day with cold air coming from the vents, but the house temp. will not drop below 76, and as a result, never cycles on/off. The house will cycle on /off at night, once it gets cooler outside. He also took the temps. of the return and supply air. He told me that I had splits of 20 degrees, and stated the pressures were all where they needed to be. He does not know why my house still is cooling during the day time when the sun is out. What could be the problem?? Any help would be appreciated. Thanks in advance.
