You have three choices for your next furnace in New York City or Long Island.

Like most purchases, your choice will depend on budget and personal preference.

Single stage

The single stage furnace, the least expensive, is either on or off. It reaches the number you desire on the thermostat and then stops. It’s probably best for a smaller house or a home you don’t plan to own long-term.

One downside: It starts at full blast and expels some cool air before the warm air. It also can provide uneven heat in multistory homes.

Dual stage

A two-stage furnace offers two speeds when it’s on: low mode or high mode. Low mode does most of the work, but the furnace kicks into high mode at particularly cold times. This allows the furnace to be more energy efficient and quieter than the single-stage model.

Cost is the most common objection to the two-stage furnace, but it is more effective with energy usage and it delivers even coverage of all rooms in your home or business.

Variable Speed

This technologically advanced model delivers consistent air flow throughout the home or business, eliminating the feeling that some rooms are cooler than others. Air filtration and air flow also are good.

Price is the big factor because it’s the most expensive furnace, but it’s less daunting if you plan to stay in the home for an extended period. The average furnace will work for 15 to 20 years if it is well-maintained.
