Sean from Shamrock Heating & Cooling came to check out my air conditioner ... after I had another company check it. My unit was 12 years old and my compressor was burned out. I ended up buying a new unit and now have a 10 year warranty for partsand labor, plus 2 tune-ups a year from Shamrock and that's at half the price the other company quoted me. I now have peace of mind next summer or summers after when something goes wrong ... Shamrock comes the day you call. I believe most of us in AZ have home warranties mainly for our air conditioners. But they only bandaid what they need, and then again when something goes wrong, usually after waiting a few days for that. I no longer need a Home Warranty since I have Shamrock. So glad I found them .... thanks Sean!
