The first cold snap in November is when most NJ heating problems show up. The furnace runs all summer with the cover on, you flip it to heat, and nothing comes out warm. Novus Mechanical is the heating contractor Freehold and Monmouth County homeowners call when they want the real cause found, not a guessed-at part swap, because improper installation alone can cut a system's efficiency by up to 30%, according to ENERGY STAR.
Here's what sets the work apart. We measure before we quote. Static pressure, a load calculation, the combustion side of a furnace. The numbers show what's actually wrong, so a repair holds through the winter and a new system is sized for your house instead of copied off the old box.
This page is the way into all of it. Find the service that matches what you're dealing with below, or call and we'll point you the right way.
Not sure where to start? This is the fast way to match what you're dealing with to the right service.
| Service | When you need it | What Novus measures first |
|---|---|---|
| Furnace installation | The furnace is past about 15 years old or beyond repair | A Manual J load calculation, room by room |
| Furnace repair | No heat, short-cycling, or a furnace that will not ignite | Ignition, flame sensor, combustion, and airflow |
| System check-up | Once a year, before heating or cooling season | Static pressure, temperature split, airflow, combustion |
| Thermostat services | A blank screen, short-cycling, or a room that never hits the set temperature | Thermostat wiring, and whether it is the cause or a symptom |
| Heat pump repair | No heat or no cooling from a heat pump system | Refrigerant charge, static pressure, and electrical components |

Novus measures before recommending heating equipment because a new furnace can't fix a problem it never measured, and that's the gap most heating quotes skip.
Picture a house that never heats evenly. One contractor looks at the old furnace, sees it's tired, and quotes a bigger one. Reasonable on the surface. The trouble is an oversized furnace is its own problem. It blasts heat, hits the thermostat fast, and shuts off before the far rooms catch up. So the back bedroom stays cold, the unit short-cycles itself to an early grave, and you paid more for a worse result.
Right-sizing is the answer, and right-sizing means a Manual J load calculation. That's the industry-standard math for matching a heating system to the actual house. It accounts for:
We run it before any replacement. When the symptoms point at airflow, we check static pressure too, because a furnace fighting a choked duct system burns out no matter how new it is.
Heating adds one thing cooling doesn't: safety. A gas furnace burns fuel inside your home, so the combustion side has to be right. We check it. A cracked heat exchanger or a furnace starved for air isn't a comfort issue, it's a carbon monoxide risk, and the CDC ties hundreds of deaths a year to it.
The payoff shows up two ways. A system sized to the home runs longer, steadier cycles, holds an even temperature, and costs less to run. And it cuts callbacks. When the repair hits the real cause and the equipment fits, you're not calling us back in three weeks for the same cold room. Do it once, do it right.
Our technicians hold the credentials that back this up. NCI Residential HVAC System Performance Technician (#25-142-01), NCI Residential Air Balancer (#25-143-01), and EPA certification #P165BDDE28EAD0701. The performance and air-balancer training is exactly what lets us measure static pressure and airflow and turn the readings into a system that's verified, not just swapped in.

Repair usually wins on a furnace under about 15 years old with one failed part, and replacement starts to make more sense past 15 years, with a cracked heat exchanger, or when the repair eats a big share of a new unit's cost. That honest answer depends on age, the part that failed, and the math, not on which contractor happens to answer the phone.
A furnace under about 15 years old with a single failed part is usually worth repairing. Push past 15 years, add a cracked heat exchanger or a repair that eats a big share of a new unit, and replacement starts to make more sense. A dying furnace nickel-and-dimes you one part at a time, and each part is older than the last.
We run those numbers with you instead of pushing repeated repairs on a system that's done. If a repair is the smart call, we say so. If you're throwing good money after bad, we say that too. Start at furnace repair and we'll tell you straight which side of the line you're on.
Novus services all major heating brands, including Mitsubishi, Daikin, Bosch, Amana, Carrier, Trane, Lennox, Rheem, Goodman, Fujitsu, and York, so you're not hunting for a contractor based on whose name is on the furnace.
If your equipment isn't on that list, call anyway. What matters more than the label is whether the system was sized and installed right, and that we can check on anything.
