When a home's heating or cooling systems fails, most home owners do not know what to do and call for a professional. Knowing some basic information about how heating and cooling systems work may help you deal with system mishaps by yourself. Take this quiz and see how good your knowledge of heating and cooling system basics is.
Air conditioners are powered by electricity.
A heat pump heats and cools the air.
The pipes used for hot water may slant in the wrong direction.
The key component is a bimetallic element. The element expands or contracts as your home's temperature changes.
A solid-state electronic thermostat is used to control the air of modern heating and cooling systems.
When they cease to operate, these thermostats must be replaced.
Solid-state thermostats may be more accurate than older models.
Most modern radiant systems are built into homes with a concrete slab foundation.
Climate-controlled systems have three basic components: a source of warmed or cooled air, an air distribution system and a control to regulate the system.
A thermostat is used to regulate heating and cooling systems.
A furnace is a usual source for warm air, but an air conditioner can also be set to heat as well as cool.
An air conditioner is your usual source for cool air.
In homes with central air conditioning, cool and warm air usually share the home's air ducts.
Air is distributed by forced-air, gravity or radiant systems.
A forced air systems uses a blower to force air through a home's duct system.
The principle of hot air rising and cold air sinking is the basis of the gravity system.
At the source, a boiler is used to heat water.
Problems with the blower is a common issue for forced-air systems.
The principle of heat moving from a warm object to a cooler object.
The thermostat usually regulates both the heating and cooling systems.
