Arrive to home and spoke with customer, she told me a previous company was out and did a bunch of repairs. When I opened the unit up, I found wiring burned that needed to be fixed. Normally this is due to loose connections and heat buildup. Customer told me to only do repair today, however, we did talk about installing a in rush device to lower the starting amps and about doing preventative maintenance. The only other estimate I left was for the Remi halo because homeowner mentioned that his wife has asthma and bad allergies. They are extremely beneficial unit to have in your air conditioning system. Unit running at departure with a 23° temperature differential.
