I HAVENT FINISHED WITH THIS PROJECT I WILL RATE YOU AS EXCELLENT. ON MY EQUIPTMENT THE HEAT STRIP WAS NEVER HOOKED UP . THE 220 IS DIRECTLY INTO THE AIR HANDLER. ALL THE LOW VOLTAGE WILL BE HOOKED UP. MY QUESTION IS CAN WE FORGET ABOUT THE HEAT FOR NOW - AND WILL THE VARIABLE SPEED AIR CONDITIONING WORK UNTIL I FIND HVAC PEOPLE I CAN TRUST
