"not only carrier"
I've been reading reviews because I'm buyging a new system....My question to the installers...how do you know. I found out that the people who originally installed my unit did wrong things, the people the came to repair it did funky things...and I thought I was using reputable people.

"HVAC UNION CONTRACTOR STEAMFITTER"
The number one complaint is coil freeze up. The number one problem we find is incorrect installation. I know, you all have heard this before. When we install in a new home, everything is new. We vacuum system down to 350 Microns, which let us know if we have any leaks or non-condensibles. I've seen reputable companies with bbb awards skip this process or not do this with micron gauges. This is a MUST! Second, we purge with nitrogen. Then we charge system. Now, with all systems having TXV's for the metering device, we have to sub cool the system for correct charge. A lot of technicians feel this is too time consuming and just feel the suction line (big pipe) and if it's cold, they think it's working. Wrong, we use a chart and a digital thermister and check liquid line. A lot of complaints about evaporators rusting is due to unit being over charged with refrigerant, or duct work not sized correctly. We size ducts with a ductulator. A/Cs that are grossly overcharged will condensate a lot, more than normal. I do find manufacturer defects in all brands and it upsets us that some companies cut costs by using sub standard materials. We can find these issues at start up by sub cooling or super heating equipment. I also read about faulty txv metering devices. A lot of these I find are over heated with the torch during install. I'm sorry not every tech is trained nor is the owner of some of these HVAC businesses. It is giving everyone a bad name. There is a set up for furnace also. It is called temp. rise. We set that with blower speed. It is too hard to find a good contractor that is going to go by these industry standards, but if you ask questions about sub cooling and super heat and watch their reactions, that should let you know if you have a good tech. It is not always mfr's issue. Good luck!
