Shamrock Heating & Cooling Shamrock Heating and Cooling Inappropriate, Disrespectful Opportunists Tempe Arizona

I called Shamrock because my a/c was blowing warm air.  The unit was installed by Shamrock less than 5 years ago and came with a 10 year parts and labor warranty.  At that time, I dealt with Sean and Shamrock was the lowest of 3 estimates I got for replacing my heat pump.  This time, however, I suspect I was ripped off.  The technician was friendly, but wasted no time in establishing that I knew nothing about HVAC systems.  After diagnosing the cause of the problem (covered by the warranty), he just happened to find several items that needed attention that were not covered by the warranty and implied that failure of my system was imminent if I did not have these parts replaced, repeatedly using 'industry terms' for things and saying how hard it was to explain them to me, because I don't know anything about how heat pumps and electrical systems work.  After he humiliated and scared me into agreeing to $900 worth of [likely unnecessary, possibly non-existent] work, he insisted on using my hose to do the cleaning of the system, even though I warned him it was not long enough to reach my second story roof.  So now my hose bib and rain gutter are bent from him yanking the hose.  I just hope he didn't damage my roof.  The technician also mentioned more than once that he'd been working for 13 days straight with no time off and asked me to rate his service on a scale of 1-10 right then and there, which made me very uncomfortable.  I feel stupid and sick to my stomach for not getting a second (or third) opinion, but being without a/c in the Phoenix heat and not wanting to have to take a day or more off work to be home and get more estimates, I just caved and got the work done.  Next time I need a/c service, I'll be sure to get estimates from several companies, but Shamrock won't be one of them.
