  • How Does a Central Air Conditioner Work?
    Written by
    With our steamy hot Pennsylvania summers, a central air conditioner is not just a luxury, it's a necessity. Air conditioners work hard to keep our homes comfortable, but have you ever thought about how they work? Here's a brief overview.

    Split Systems

    A typical central cooling system is a split system, meaning it consists of an outdoor unit housing a condenser coil and compressor, and an indoor evaporator coil, usually installed in conjunction with an air handler inside the house.

    The AC Compressor

    The compressor pumps a chemical refrigerant through the indoor evaporator coil. As warm air inside your home blows across the evaporator coil, the heat energy is transferred to the refrigerant inside the coil. It's this transfer of heat that cools the air. The heat absorbed by the refrigerant is sent outside while cooled air is blown back inside. This condensing process also removes excess humidity from the air.

    Air Ducts

    A home's ductwork is designed to distribute conditioned air throughout your home, it also returns air to the air handler to repeat the process again.


    The thermostat is the "brains" of the central heating and cooling system. Once the temperature is programmed, it maintains an even temperature. Some thermostats can be programmed to work on a schedule, saving energy when the house is unoccupied.

Customer Testimonials

"Our AC unit failed in the afternoon.  Maitz was the only service we were able to contact that evening and schedule for the next day.  They said they could call on us first thing  the next morning.  They arrived on time, diagnosed the problem, had the parts to fix it and did.  Not to mention it was literally the hottest day of the year, so we were pleased they could accomodate us on such short notice.  We spent a little more than we had hoped, but were able to stay cool that day.  They also reccommended a cleaning of the unit, and when we declined described the problem and how to address it ourselves.
Very courteous, very professional, just a bit pricey, but hey the repairs will likely extend the life of our AC for a few more years anyway."
