Your home’s heating needs can account for up to two-thirds of your annual energy bill, so it’s important that we inspect your current furnace to ensure it is not too old, too large or too small for the job it is being asked to do.
Furnace Installation, Replacement and Repair
Before you think your decades-old furnace is “good enough,” consider that modern high-efficiency furnaces can be up to 95% fuel-efficient—something unimaginable even ten years ago. What percentage of fuel is your furnace using, compared to the percentage being wasted? When a repair is in order, we stand by our quality work and put warranties on any parts we replace. However, with the efficiency of modern furnaces, having a new furnace installed is also a good option as you will begin saving money on heating immediately.
Should your furnace only require a quick tune-up, we can often handle it during the same visit. We service all brands of furnace and heating systems including, Lennox, Trane, Carrier, Bryant, American Standard, Rheem, York, and Goodman.
If a replacement would be a better option for you, we will tell you why, and go through the best options for your home and budget requirements.
More than anything, we feel our responsibility is to ensure that you enjoy worry-free heat and comfort at the lowest annual cost.

A Brief History of Furnaces
Many people don’t realize that the modern furnace is actually a relatively new invention. Before 1885, most homes in America were heated via wood that was burned in fireplaces and pot-belly stoves. Just fifteen years prior to the turn of the century, however, the first coal furnaces were built from riveted steel. These early furnaces were unique in that they did not utilize electricity or fans in order to move air; rather, they were able to transport heat via convection, which occurred naturally and brought heated air from the basement furnace to the rooms above via a series of ductwork.
Cast-iron radiators would be the next invention to change the landscape of home heating. Thanks to this innovation, coal-fired boilers located in the basement could now deliver hot water and steam to each room in the house. Both of these methods dominated the landscape of home heating until the introduction of “forced-air” furnaces in 1935. These types of furnaces distributed heat via an electric fan, although coal was still used as the primary fuel source. While available towards the end of the 19th Century, central heating really didn’t become common until the late 1930s.
As coal would begin to fall out of the limelight, the same type of furnace would eventually incorporate Natural Gas and Fuel Oil as alternative fuel sources; no more would homeowners have to stoke a coal fire, which was a rather labor-intensive process.
From these relatively simple beginnings, the central heating system became the Comfort Standard for modern living. Today’s furnaces are built with energy efficiency in mind, with features such as multi-stage gas valves & variable-speed blower motors; all contributing to increasing the home’s comfort while saving the homeowners significant amounts of money on their heating bills, even during the coldest of New Jersey winters.
How does a furnace work?
Heat is generated by burning natural gas or propane inside the furnace. This happens in the combustion chamber, which gets very hot. Air absorbs this heat in the furnace’s heat exchanger. Next, the blower sends the heated air through a system of ducts, and warm air circulates through the home.
What is a cracked heat exchanger?
The heat exchanger is the main component of your furnace. If the heat exchanger has a crack or a rust hole, combustion fumes (including carbon monoxide) can contaminate the air in your home. This is a potentially deadly situation and should be addressed IMMEDIATELY. A cracked heat exchanger usually requires replacing the entire furnace. If you suspect that you might have a cracked heat exchanger, or a carbon monoxide problem caused by your furnace, turn the system off immediately. Then call us right away for service.
On mild winter days my furnace runs in short blasts and my home alternates from being too hot to being too cold. How can I fix this?
Installing a new furnace with 2 levels of heat and a variable speed motor is a good solution. These “smart” motors automatically adjust the volume and speed of air based on your home’s temperature requirements.
There will be fewer on/off cycles, smaller temperature swings, consistent, even heat, and lower fuel bills.
