Have you wondered what the main components to your HVAC system are and how they heat and cool your home and office?

There are a couple of different kinds of coils. There are condenser coils and evaporator coils. The condenser coil manages heat exchange and condenses the refrigerant gas (which is hot). After the condenser coil does it's job it passes off to the evaporator coil and releases the refrigerant to it. The evaporator coil then turns the release into cool air and blows it throughout your home or office in the duct work.

I am sure at some point in your home you have heard mom, dad, or anyone else yell out, "Who changed the thermostat?". This is a common thing in a household. Disagreements can arise over the house thermostat, trust me, I have seen them. Not everyone in the house though may like the same temperature. If you are looking to find a solution, Lancaster Heating & Air with our professional heating and cooling techs may have some simple tricks to keep everyone happy. With women usually being more on the chilly side and males on the warmer, we have to find a happy medium for all.
