It costs around $100 for the pump and gauge set to do it yourself. I've found that HVAC guys want to do the FULL install, otherwise they won't even do simple service on it. My experiences: 1st system, 18Kbtu unit in the cabin - HVAC guy did it, really simple install: $5000 2nd system, 9Kbtu unit in my shop office, did it myself. $600 for unit + $100 for tools. Been working for 2 years. 3rd system, 36Kbtu, 4 head unit in rental. ~$2000, did it myself, been working fine for over a year. 4th and 5th systems, 9K btu each in my house. Each cost about $700. I made an error on one and screwed up a fitting and lineset. Called 5 local HVAC guys. 4 refused to even look at it, the 5th wanted $600 for the initial service call. So I fiddled with it some more, did some damage, and decided to just replace the whole unit. Another $700. Still WAY WAY cheaper than having it installed by an HVAC guy. -- Bobcats and Cougars, oh my! http://john.casadelgato.com/Pets _______________________________________________ Address messages to [email protected] No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/ LIST INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
