What is two-stage heating?

Two-stage heating means the furnace has two levels of heat output: high for cold winter days and low for milder days. Since the low setting is adequate to meet household-cooling demands 80% of the time, a two-stage unit runs for longer periods and provides more even heat distribution.

Why should I zone my house?

A zoning system is designed for the many ways you use your home. Maybe you're caught up in family "thermostat wars?" Or perhaps you have unoccupied areas that do not need conditioning? A Lennox® zoning system allows you to divide your home into separate areas, giving you the comfort and control you've always wanted.

Zoning can give you more comfort, efficiency, control and quiet performance. Make sure to ask your Certified Technician for ideas on zoning your home.

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.

To learn if a dual-fuel system is right for your home, you can discuss this with our Certified Technicians.

Will my new furnace work differently than my old one?

Furnace technology has advanced significantly in recent years. Modern furnaces are designed to provide more efficient and even heating than old furnaces, which can impact both how your system operates and what you notice about your system.

To better regulate temperatures and airflow, modern furnaces move more air over the heat exchanger than older furnaces. The air that comes out of your furnace registers may not seem as warm as the air from your old furnace, but overall airflow is improved. Better airflow means higher comfort.

Also, new furnaces are designed to integrate with high-efficiency air conditioners, so furnace blowers are more powerful to accommodate add-on cooling. Since cold air is much heavier than warm air, your system needs an extra boost from the blower to deliver cool air throughout your home. If you have an older home, this performance boost could produce unfamiliar sounds because air duct systems were originally designed for heating only. To minimize sound levels, choose a variable speed furnace which automatically changes speeds to meet the airflow needs of both heating and cooling cycles.

Why is it important to have regular maintenance on my new furnace home comfort system?

You wouldn't buy a brand-new car and expect to never have to put air in the tires, change the oil and check out any unusual noises, would you? In the same way that an automobile requires periodic maintenance for optimal performance, a home comfort system should be regularly inspected by a qualified technician.

How can I find out about rebates and tax credits on my new HVAC equipment?

The first thing to know is rebates are only available through companies that are certified through the North American Technician Excellence program (NATE). The first thing to ask any furnace Dealer is if all their Technicians are certified through this program.

Various rebates can be available through the Lennox company, your utility provider and your Dealer. There are also tax credits available from your state and federal government.

Due to changes over time the only way to get an accurate picture of which rebates and tax credits are available at any one time is to call Welzig Heating and Air at 303-678-5576. We will be happy to answer all your questions.
