"Tech said that the Freon leaked out and that the compressor burned out because of it. Quoted $4800 to replace compressor and recharge, or $7,000 for a new AC unit. Got a second opinion and hired a handyman. Turns out the breaker was tripped and needed some fiddling with. AC works great now. Can’t believe they were going to lie about what was wrong to replace the whole AC. Just because it was an old unit. Get a second opinion for them if they tell you something similar."

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.
