This is how you have to do it
I had an estimate for 2300 for just the outside unit so i said i'll think about it mean while i went online to get my epa certification.
It only cost 25 dollars for tech 1 and that is good for less than 5 pds freon units so i bought my unit from ebay 1000 and the pump, recovery tank gauges the hole 9 yards total i have in it is 1400 installed in 1 day.
they wanted 800 for just labor this is a rip off market in the hvac world. Any fool can pass that test and do the work themselves you have to because the idiots in this field think they have one over on you and charge you thousands for a days labor.. ill never call an hvac dude again no thanks charge someone else a thousand for sitting in a chair waiting for a vacuum pump to do its thing..
