Air Handlers and Heating

Usually the air handler is the unit that provides heat, but some more advanced commercial and residential heating systems use zoning with remote heating. In this case the handler just provides air while the heaters provide zoned heat. Even inside air handlers there are multiple forms of heat energy.

You can have electric heat strips which are like super hot ribbons to heat air with. For chemical heat, gas and oil furnaces are popular with Denver furnace services companies. Some units heat a liquid which then warms the air through a heat exchanger. Hot water coil and heat pumps are examples of this type of technology. Hot water coils usually use a fossil fuel to heat the water, while geothermal heat pumps use the energy from the ground.

Electrical energy is the most common in commercial Denver HVAC applications. Electrical energy does not waste as much energy as the combustion of fossil fuels in furnaces, however electrical is still more expensive per unit of energy than any other alternative. Electrical heaters generate heat by passing high voltage electricity though a metal resistance strip. They use a lot of energy, so you need to make sure both the electrician and Denver HVAC engineer are on the same page putting in all proper wiring and and circuit protection.

All wiring needs to be well insulated for this type of high energy electric work. You need circuit protection and fail safe breakers that will shut off in the event of a short or overheat.

Remote heating in air handlers use a switch to energize the heater when air flow is detected. This is important to have air flow to keep from wasting energy and reduce the chance of fire. This is an added risk with heaters all over the house. On the other hand, for buildings that will only need heating in certain locations, zone controls can result in significant savings. Remote heaters can even be gas duct furnaces. Zoning can be installed by a Denver furnace repair company, and they not only save money but also result in more even heating. They provide heat by burning gas in the ducts, but they also need air flow when operating.
