How does a furnace work?
Furnaces play an important role in keeping your home or business warm, so you may
be wondering how these important devices work. Furnaces typically run
on natural gas, propane, oil, or electricity. In many furnaces, the air
is heated using the energy source and then pushed into the home through
ducts and vents.
The thermostat on the furnace activates the device to move more hot air
into the property once it determines that the heat has dropped below a
certain point. A professional trained in furnace systems understand how
to install, repair, and replace heating systems should anything go wrong
with this process.
How does a humidifier work?
Dry air can have a drastic effect on your health and home. Not only can
this cause respiratory irritation, but it can affect the indoor temperature.
Humidifiers work with your existing HVAC system to maintain adequate moisture
conditions within the home.
Humidifiers have sensors that determine the amount of moisture in the air.
If the percentage of water dips below a certain point, water vapor is
added to the circulated air until it reaches an acceptable percentage.
How does an air conditioner work?
Air conditioners help to maintain a comfortable temperature and control humidity within
the home. As a part of your HVAC system, your air conditioner plays an
important role in helping you maintain comfort.
AC units work by:
- Moving warm air from the room into the HVAC system through grates;
- Air flows over pipes filled with coolant fluid to chill the air;
- This air is pushed back into the room using fans;
- Heat absorbed from the air as it passed over the coolant is pushed outside
using fans; and
- The resulting air inside the home is cool.
How does a heat pump work?
The main purpose of heat pumps is to move hot air from one place to another.
It is a heating and cooling device that maintains the temperature of your property.
Heat pumps typically work by moving warm air into the existing ductwork
using a motorized fan. Refrigerant is used to absorb the heat as it passes
over the system. Depending on whether you need warm or cool air, heat
is either moved into the home or pushed outdoors, maintaining the ideal
temperature no matter what season.
