Residential central air conditioning has a long history going back to the 1920s. But many decades would pass before central AC systems became common and affordable for homeowners.

As spring approaches, it’s a great time to give some thought to making an upgrade to your old HVAC system. If your heating and air conditioning system is more than 15 years old, or it has started to require more repairs while running up steeper utility bills, this is probably the year to have the system replaced—and with one that’s more efficient than your old system was even when it was new.
