The contactor is an electrical switch in the condensing unit of your central air conditioner. The switch controls the electrical signal traveling between your indoor thermostat and that outdoor condensing unit. If the contactor is open, the unit knows to keep providing cooling services to your home while a closed contactor says to shut down shop.
A malfunctioning contactor can keep your air conditioner from turning on at all or keep the unit running well past the cooling level you desired.
In the midst of summer, you may find yourself running your air conditioner very often, which can rack up a huge electricity bill. However, there are ways that you can reduce your cooling needs to make the most of your cool air. Here are some proven ways to reduce your AC bill.
Get an Inspection
The first thing to do is to get an inspection of your HVAC and AC systems to root out any problems.
One of the best alternatives to traditional heating methods is radiant heating. A radiant heating system is a bit different from a traditional forced-air heating system because it does not utilize a furnace. Instead, this system uses either electric panels or water pipes located underneath the floors and within the walls of the house.
A radiant heating system that uses water pipes will typically utilize hot water from a boiler to heat up the walls and floors, which in turn heat up the house.
