Yesterday, after their technician looked at my unit he told me to change it for $5222 at 12:00pm since the compressor was supposed to be 90% damaged and my system is an old one (R22) I needed to replace it all. Likewise, he would be able to replace it the next day; so, I told him to put it to work at least that day because I left my handicapped mom and another person there and I was working, Houston yesterday was 100+. He charged me $533 for replacing a ""capacitor"" ($50 price found on the web), a ""contactor"" ($30 price found on the web), and diagnostic as per invoice (no warranty & no freon charged). Of course, this money it was refundable ""IF"" I change the unit in one week. When I got home @ 4:30pm it was fresh instead of cool, 84 degrees as per thermostat, set at 79. So, I decided to get a 2nd opinion, 5000 buck is a lot of money. These 2nd people showed at 9:00, after their last work, they charged 4# of freon (I could feel the temp going down) and told me it could be a leak; so they told me to keep looking the temperature during the night. I woke up this morning and the system was still working smooth and cold 75 it was reset to 75 to test it. I called Arvell Moore to complain about what happened and they just told that technician was one of their top one; they will call me after talking to him and I am still waiting for their call. By the way, I was supposed to have 50% discount to be a new customer on repairs as per their web page, but it wasn't honor.
