Here in late August, my fairly new HVAC unit started working intermittently. My thermostat was not controlling the operation of the unit. So I called up Booker HVAC on Monday and scheduled an appointment for the next day. Service was timely, thorough and affordable. It was explained to me, in a way that I could understand, that the problem was likely the float switch. Now my blood pressure and my home temperature are COOL! If needed, I would without question call on Booker HVAC again.
