The inspection was, to my knowledge at the time, professional and thorough. Of course, I was (and still am) ignorant of what else could be checked to pinpoint the problems that were discovered. I felt that the inspection, although very courteous, friendly and professional, was a big set up to sell me their products. When I asked if there was a discount for purchasing two whole new sytems the inspector said yes and verbally quoted $10,000. When I received the quote it came to $12,350...with a very tiny scribble indicating that there was 5% discount. I figure the guy realized my ignorance regarding a/c systems and used this against me. He even went so far as to say, "I'm sorry, I don't work on commission, but this is what I found. I know this is a lot of money, and if my wife were to agree on something like this without my consent I wouldn't be too happy about it." So today I am getting another a/c tune up anf 15 point inspection from another service provider (Air Tech of Houston) who might be able to pinpoint the real issues with both systems instead of trying to sell me $12,000 for two a/c systems.
Description of Work: My townhome was bought in October 2009, and the inspection reported no a/c issues with neither the coils nor the condensers. (There are two split systems, one "newer" 3 ton Carrier unit for the first and second floors and another "older" 2.5 ton for the top 3rd floor). Water pans drained correctly and there were no freon leaks detected. A week ago, when the weather went from freezing to mildly warm, I turned on the "newer" a/c system and there was a horrible sound coming from outside. So I turned it off and called the number on the unit, which is Air Specialist. They were polite and professional, said they would charge $69 for inspection and quote and we made the appointment for the next day (last Tuesday). The service man who came, "Leon", was likewise polite and professional and brought a freon tank, a pressure manifold, a freon leak detector, drill, etc. At the time I was completely ignorant of how an a/c system works or what might be required to fix the system. He asked that I turn on the a/c and I did, and he immediately turned it off (there is an external switch wired to the exterior wall). He asked that I turn off the other unit which sits right next to the one being serviced. Once I came back down from the 3rd floor and went outside to he declared the exterior valve was in need of replacement, he showed how if you tighten it it would s*** out freon and oil, and he smelled his fingers saying that the gas and oil smelled burnt, indicating that the compressor is likely in need of replacement. I asked how much to replace the valve and the compressor and he told me that there is a "new system" regulated by a law that went into effect last year where he couldn't change the compressor without changing the evaporator coil in the attic. That alltogether the whole system, plus 10 yrs parts and labor warranty, would be $6000. Of course, I tried to understand if we replaced only the equipment that was faulty (with a "new" lower pressure/ higher efficiency compressor) would the system work and he said he would need to check the coil boxes in the attic to see if these are compatible. He repeatedly said they only sell the newer system and could not retrofit with older model compressors, etc. So we went inside, (yes, very polite and clean, used shoe protectors) and climed to the third floor, as he went into the attic he said, wow, I can't believe it, you have the original coil systems that were installed when the house was built. Which meant that no, it was not the new system coils. Then he mentioned that he needed to clean/ dry out the water pans to check for clogging. But there was no issues at all with coil box, pans, etc, but he said he didn't understand why there was buildup on the exterior spout, so he traced the pans back to my other unit (the older, smaller system in use for the 3rd floor) and opened up the panel to find that it had frozen into a solid block of ice at the bottom of the coils. At that point I went up into the attic to see for myself and upon seeing the evidence I became more convinced of the need to replace both systems, coils and compressors, but not knowing that this could be the fan, the fan relay, the connection with the thermostat, the blower motor, etc. The technician said that this is due to a freon leak in the coils (of the 3rd floor system), and since I still don't know any better I believed him. Also, the replacement of the valve and the compressor outside of the 1st/2nd floor a/c could be all that is required, with a good cleaning of the unit.
