Furnace Installation & Replacement in New Jersey

A properly installed high-efficiency furnace keeps a New Jersey home warm through the coldest stretch of winter while cutting gas bills compared to the 20-year-old unit it replaces. Heating Cooling NJ installs gas and propane furnaces in homes throughout the state, from compact closet installs in Hudson County condos to large two-stage systems in Morris and Somerset County colonials.

Every furnace replacement starts with a free estimate, a load calculation and a frank conversation about efficiency levels, so you understand exactly what you are buying.

Choosing the Right Furnace

Gas furnaces are rated by AFUE. An 80 percent furnace vents through a metal flue and suits homes where a chimney liner is in good shape. A 95 to 98 percent condensing furnace vents through PVC, produces condensate that must be drained and uses far less fuel. Single-stage furnaces run at full output every cycle, two-stage furnaces run at a lower fire most of the time for quieter, more even heat, and modulating furnaces with variable-speed blowers adjust continuously for the best comfort and lowest operating cost.

We walk through each option and recommend the configuration that fits your home, budget and how long you plan to stay.

Sizing Matters

An oversized furnace short-cycles, wears out faster and leaves rooms uneven. We perform a Manual J heat loss calculation that accounts for your square footage, insulation, windows and New Jersey design temperatures, then select a furnace with the correct BTU output. We also check that the ductwork and return air can handle the blower, which is often the hidden cause of a noisy or underperforming system.

Our Installation Process

The crew shuts off gas and power, removes the old furnace, cleans the plenum, sets the new furnace with proper clearances, connects supply and return with sealed transitions, installs new gas piping with a drip leg and shutoff, runs new PVC venting and condensate drain for condensing models, wires the thermostat and safety controls, and fires the system. We measure gas pressure, temperature rise, static pressure and combustion to confirm the furnace is operating within manufacturer specifications, then register the warranty.

Pairing With Air Conditioning

If your air conditioner is also aging, replacing the furnace and AC together as a matched system reduces labor cost and ensures the blower, coil and condenser are designed to work together. We can also pair a new furnace with a heat pump as a dual-fuel system that uses the cheapest energy source at any given temperature.

Rebates and Financing

High-efficiency furnaces may qualify for New Jersey Clean Energy Program incentives and utility rebates. We identify eligible equipment and submit the paperwork. Financing is available for approved homeowners, and estimates are always free. We install furnaces in all 21 New Jersey counties.
