Prompt, professional, solved my problem. My AC suddenly stopped working during a heatwave and wildfire smoke so this was URGENT. I called COHC at 2pm and they said they could get someone to come over that day before 7pm (the other company I called said they couldn't get to me till Tuesday!). Spencer showed up a couple hours later, diagnosed my problem, (capacitor), and despite there being an active wasp nest a foot away from the unit (inside the breaker box) and I said they could wait til the next morning it was his call, he still braved it and quickly fixed it! SO GRATEFUL!!! Also, the lady who made the reservation was super sweet.
