Job Locations and Reviews
Completed spring AC maintenance on a 2-ton Carrier unit. Condenser coil cleaned with foaming cleaner, amp draw on compressor at 8.1A (within range). Capacitor tested 39.6 µF out of 40 µF spec. Refrigerant levels normal. Checked float switch operation and cleaned drain trap. All components functioning as expected for cooling season.
AC system not cycling properly. Traced issue to failed thermostat wire shorting Y and G terminals. Re-ran 18/5 low-voltage wiring, sealed connections with silicone to protect against attic heat damage. System now starts and shuts off correctly. Also tightened loose wire nuts in air handler junction box. System tested through full cooling cycle.
Customer had high humidity and inconsistent cooling. Found blower wheel caked in debris and motor capacitor weak (tested 4.1 µF out of 5 µF). Removed blower assembly, cleaned wheel with degreaser, replaced capacitor, and reset blower speed for high cooling. Post-repair humidity dropped from 68% to 51% indoor RH within 2 hours.

4th of July, heat index 107 and our air conditioning developed problems, called Charlie's to get on the list. Expected that they were probably covered up due to the heat. Was extremely surprised to get a call from Shawn saying he could be there in an hour. He found the problem quickly and had us back in the comfort zone. Have always had great service from Charlie's and this just reinforces that.
We are so happy that Shawn could take care of you on the 4th! We really appreciate you taking the time to let us know how much it means to you. Thank you for being a customer, and give us a call any time!
