Your furnace is getting old, and you can feel it. The heat is uneven, the bills keep climbing, and you are tired of paying for repairs on a unit that is on its way out. Novus Mechanical handles furnace installation and replacement across Freehold and Monmouth County, and every job starts with one question most contractors skip: what size furnace does your home actually need?
Most of the time, the old furnace was guessed at. A contractor matched the new one to the old one, and the old one was too big to begin with. We do it differently. We measure your home first, then we recommend. That is the whole point of a diagnostic-first company.
If your furnace quit on a cold morning, the first real question is whether it is worth saving. A furnace under about 10 years old with a small failure is usually a repair, not a replacement. We will tell you that honestly.
Replacement makes more sense once a furnace is over about 15 years old, has a cracked heat exchanger, or needs a repair that costs a large share of a new unit. A cracked heat exchanger is the big one. It can leak combustion gases into your home, so we do not patch around it.
We run the numbers with you instead of pushing repeated repairs on a dying system. If a fix buys you a few more good years, that is what we will tell you. When you are weighing one more repair against a new unit, our furnace repair page walks through what is worth fixing and what is not.
Find the real cause, fix it for good
Here is where most furnace jobs go wrong. The contractor reads the old furnace's nameplate, orders the same size, and bolts it in. If the old one was oversized, and a lot of them are, the new one is too.
An oversized furnace short-cycles. It blasts on, heats the air near the thermostat too fast, and shuts off before the far rooms catch up. So it kicks back on a few minutes later. That cycle wears out parts faster, heats your home unevenly, and runs up your gas bill.
We size every furnace with a Manual J load calculation, the room-by-room sizing math the heating industry treats as the standard. It accounts for your square footage, your insulation, your windows, and how tight or leaky your home is. The result is a furnace matched to your actual house in Freehold. Manual J is the ACCA-recognized method for residential load sizing, and it is why a right-sized furnace runs longer cycles, holds an even temperature, and lasts.
Our technicians hold NCI Residential HVAC System Performance Technician (#25-142-01) and NCI Residential Air Balancer (#25-143-01) certifications, plus EPA #P165BDDE28EAD0701. Those are the credentials behind the measurements, not a sticker on the truck.
Measure first, then recommend
Most furnace replacements take about one day. We start with the home assessment and load calculation, so the price is set before we begin the work. Parts are priced up front too.
When the crew arrives, we cover your floors and protect the path to the furnace. We shut down and disconnect the old unit, then haul it away. Nothing gets left in your basement or driveway.
Then the new furnace goes in. We set it, connect the gas, venting, and electrical, and run the safety checks that matter most: gas connections, venting draft, and a combustion check so the unit burns clean. Before we leave, we walk you through the system, show you the thermostat, and confirm it is heating every room.
Once your new furnace is in, a yearly system check-up keeps it running clean and catches small issues before they become cold mornings. New equipment is covered by a 1-year labor warranty and the manufacturer's equipment warranty.
A new furnace is a real expense, and not everyone wants to pay it all at once. Novus Mechanical offers financing so you can spread the cost out, and you get the full price up front before any work begins. Ask about current options when you book your consultation in Freehold or Monmouth County.
