NORMAN had his name misspelled on the only review I found. He is a consummate professional. Taught HVAC "Back East" before "retiring" to Albuquerque. He is also an expert in Evaporative Cooling systems. Definitely _NOT_ a handyman, but a Veteran of the Marine Corps, Senior Citizen, and a thinking, intelligent troubleshooter and repair technician on any kind of cooling systems, though here in Albuquerque he mainly works on "Swamp Coolers". He came to my house where the swamp cooler had been noisy and ineffective for quite some time. Diagnosed the problem finding "wallowed out" pillow bearings, a fan shaft with flat spots where it had been riding on the old bad bearings, as well as other milder issues. He was able to adjust the shaft to an undamaged area and put in a locking collar so the new ball bearing "pillow bearings" he installed and the shaft would roll on new interfacing surfaces. The cooler now operates like brand new. This is the man you want working on repairs and service of your Evaporative Cooler! read more
