Its 116 degrees in Las Vegas and every good AC service firm cannot set an appointment for less than 10 days out. Nevada Residental Services is also booked solid. NRS could only offer an appointment next week but they immediately offerred up names of reliable competitors ( wow!!). Then when I indicated to their technician that I was handy--he offered suggestions on likely causes on the phone and even said he would make an attempt to come out after-hours tonight or tomorrow if my own efforts failed.
I was lucky the fix was something easy and within my abilities ( it was also highly suggested as the fix needed by NRS).
These guys are great. They get my highest recommendation!!
