I posted about my thermostat two days ago. I finally gave up and called a HVAC technician in. He says the capacitor for compressor and transformer for air handler needed to be changed. He said these parts were very expensive. I let him fix the problem. He also wired the thermostat properly. Well I was charged $635.00 for part and labor of capacitor. $ 312.00 for part and labor of capacitor. Went online to check prices of parts. The transformer is about $100.00 and capacitor at most $50. The company is A-1 American. I am furious that the labor (he was here for one and a half hours) cost me almost more than $700. I called the office. Office manager is supposed to call me back to "explain it to me" is this the normal cost of labor if it is then I need to change professions.
