Conventional Heating & Air

Coming to You When You Need HVAC Assistance

Airflow carries most major manufacturers of heating and cooling systems. We do, however, recommend and prefer the Lennox brand of quality heating and cooling equipment.

Here we will discuss some of the basics of heating and cooling. We encourage you to call for an appointment so we can answer any other questions we may not have covered in this section.

How does an air conditioner work?

An air conditioner seems as if it cools your home's air, but it actually makes your home less warm by removing heat from the indoor air and transferring that heat to the outdoor air.

Heat is extracted from the home by passing indoor air across a refrigerant coil in the indoor unit. Refrigerant lines then carry the heat to the outdoor unit, where it is released into the outside air. The cooling cycle continues until the indoor temperature reaches the thermostat setting.

What is a heat pump?

A heat pump is an all-in-one heating and air conditioning system that works year-round to keep you comfortable.

During warmer months, a heat pump works as a normal air conditioner. It extracts heat from inside the home and transfers it to the outdoor air. In colder weather, however, the process reverses - the unit collects heat from the outdoor air and transfers it inside your home.

Even when the air outside feels extremely cold, the air still contains some heat. The heat pump pulls the heat from this cold outdoor air and sends it inside to warm your home. When there's not enough heat in the outside air to meet the demand of the thermostat setting, an electric heater supplements the outdoor air to warm the home. Extremely efficient, this process produces two to three times more heat than the energy it uses.

Also, a heat pump can be an effective add-on option to use in conjunction with an existing gas furnace. With this dual-fuel option, the two systems share the heating load, but never function at the same time. Each system operates when it is most cost effective. The heat pump will be the primary heating and cooling system. However, when the temperature drops below the heat pump's ability to operate as efficiently as the gas furnace, the gas furnace will take over until the temperature rises enough for the heat pump to operate more efficiently.

High Efficiency Furnace

If you're in the market for a new furnace, consider purchasing a high efficiency model. They can help reduce your energy costs as well as conserve our natural resources.

When selecting a furnace, pay close attention to the Annual Fuel Utilization Efficiency (AFUE). The AFUE number represents how efficiently a furnace converts fuel to energy. The higher the AFUE percentage, the more energy-efficient or fuel-efficient the furnace will be. The U.S. government's established minimum AFUE rating for a furnace is 78 percent.

It's also important to look for Energy Star products. This means the product meets the environmental Protection Agency's (EPA) standards by using less energy, which reduces pollution. Energy Star products reduce energy use by 20-40 percent.
