It's the hottest day of the year, the AC just quit, and you have no idea if it's a $300 part or a $9,000 replacement. That's the worst part. Not knowing.
Novus Mechanical is an air conditioner repair company serving Freehold, NJ and Monmouth County that tests your system and tells you exactly what's wrong before you spend a dollar. You get a fixed price and approve it before any work begins.
AC down right now? We answer any hour, day or night.
Novus Mechanical repairs air conditioners across Freehold and Monmouth County, and every repair starts with a real diagnosis instead of a guess. You get one fixed price before any work begins, and for small parts like a capacitor or a thermostat we tell you the cost up front, so nothing on the bill is a surprise.
Your AC is running, you hear it, but the air coming out isn't cold. Nine times out of ten that's one small part, not the whole system giving up.
We handle refrigerant leak detection, thermostat repair, mini split repair, heat pump repair, and condenser coil and drain line cleaning. The drain line is the sneaky one. It clogs with algae, water backs up, and the system shuts itself off on the hottest afternoon for no reason you can see.
Heat waves here don't ease in. They land all at once. If your system is older and already struggling, get it checked in spring instead of waiting for the first 95-degree day.
Novus Mechanical installs central air, ductless mini splits, and heat pumps in Freehold homes. We run a Manual J load calculation first so the system fits your home instead of guessing from square footage.
Your house never had central air, and every June you're dragging window units up from the basement again. There's a better way to live.
Mini splits solve the rooms ducts can't reach. A finished attic, a sunroom, an addition, that one bedroom that's always 10 degrees off. We mount the head, run the line set, and you control each space on its own.
Oversizing is the most common installation mistake in the trade, and it's the reason we run the load calculation first. An oversized system cools fast, shuts off, and never runs long enough to pull the humidity out. You end up cold and clammy at the same time, and the unit wears out early. Sizing it right is the whole game.
A Manual J load calculation is the industry-standard math that tells us exactly how much heating and cooling your house needs, room by room, and Novus Mechanical runs one before sizing any system in Freehold. It starts at $350.
You got three quotes and all three sized the system differently. One of them is right, and you have no way to tell which.
Square footage can't answer the question. Two houses the same size can need completely different systems depending on the windows, the insulation, the ceiling height, how much air the house leaks, and which way it faces. We measure all of it and put real numbers into the calculation instead of eyeballing it.
What comes back is a number, not an opinion, and we size the equipment to that number. It's the cheapest line on any install and the one that decides whether everything after it actually works. If you're adding central air or putting in a heat pump, ask for the load calculation up front.
Novus Mechanical handles heating for homes across Freehold and Monmouth County, including furnace installation, heat pump installation, thermostat installation, and humidifier installation.
The first cold night of the year is when you find out your heat doesn't work. It ran fine all summer, sitting there, and now nothing.
Heat pumps have come a long way. For a lot of Monmouth County homes they now carry the house through a Jersey winter, and if you're replacing an old furnace it's worth knowing whether a heat pump fits before you default to the same thing you had. We size it with a load calculation either way, so the heat actually keeps up on the coldest nights.
Before the cold hits, we check what your system is doing instead of waiting for it to quit. A weak igniter, a tired blower, or low refrigerant on a heat pump shows up on the meters months before it leaves you with no heat in January.
Novus Mechanical repairs gas and electric furnaces in Freehold. We handle ignition and pilot repair, flame sensor and igniter cleaning or replacement, thermostat replacement, and drain line inspection. We price the small parts before we begin, and we check the heat exchanger for cracks on every visit, because a cracked exchanger is a carbon monoxide risk, not only a comfort one.
Most of the time it's the igniter or the flame sensor, not the whole unit, and a flame sensor sometimes just needs cleaning.
If your furnace is 15 years or older and the repairs keep stacking up, we lay out repair versus replace with honest numbers. Sometimes the fix is the smart call. Sometimes you're feeding money into a system that's done. You hear it straight either way.
Novus Mechanical cleans, seals, and repairs ductwork across Freehold, and in a lot of older homes 20 to 30 percent of the conditioned air leaks out before it reaches a room. We find the bad runs and fix them.
You pay to cool the whole house, and half the cold air dumps into your attic before it ever reaches the bedroom. That's a duct problem, and no new equipment fixes it.
Crushed flex duct in the attic, joints that came apart in the crawlspace, returns too small for the system. These are the quiet problems behind a room that never matches the rest of the house. Duct sealing and airflow testing balance it room by room.
Novus Mechanical runs home performance diagnostics in Freehold, including blower door testing, duct leakage testing, and thermal imaging. A blower door test puts a fan in your front door, pulls the air out of the house, and shows exactly where it's leaking.
Your bedroom never cools, the bills keep climbing, and the system runs all day without catching up. The equipment usually isn't the problem. The house is.
This is the test that explains the unexplainable. The cold room. The high bill. The system that never keeps up. Air leaks are often the real story, and no new furnace fixes a hole in your house.
We also install smart thermostats, whole-house dehumidifiers, and zoning systems. Zoning lets you cool the bedrooms at night without freezing out the rest of the house, which for a two-story home is often the fix people have wanted for years.
Novus Mechanical repairs and installs every major HVAC brand, so you call one team no matter what's in your house.
A Novus visit runs in four steps: you reach us, we measure the system, we explain the real problem with a fixed price, and nothing starts until you approve it. When your AC quits, you don't want a guessing game or a hard sell, you want to know what's actually wrong and what it costs.
Call or book online day or night. Our assistant takes your details and connects you to a person when you want one.
We come out and hook up the meters: static pressure, airflow, temperatures, refrigerant. We find what the system is actually doing instead of guessing.
We explain what's wrong in plain words and hand you one number, no upsell.
You approve the price first, every time. Work is scheduled Monday through Friday.
We measure so the fix holds, not so we are back next season.
Novus measures your system and your house first, static pressure, airflow, refrigerant, and air leakage, before recommending anything, on purpose. Most HVAC companies sell a part or a whole new system before they actually know what's wrong, and that's how people end up paying to replace equipment that was never the problem. It costs a little more time up front, and it saves you from the expensive mistake of buying the wrong fix.
That approach is what our NCI (National Comfort Institute) training and EPA certification are built on. It is the reason our repairs hold and our installs run right the first time.
Here is the full toolkit, and what each measurement changes about the recommendation you get.
| What we measure | What it tells us | What it changes about the recommendation |
|---|---|---|
| Manual J load calculation | The exact heating and cooling load your home needs, room by room | Sets the equipment size, so we never install on a guess from square footage |
| Blower door test | Total air leakage in CFM50, and where the leaks actually are | Shows whether sealing the house first beats installing a bigger system |
| Duct leakage test | How much conditioned air the ducts lose before it reaches a room | Tells us whether duct sealing gets you more comfort than new equipment would |
| Static pressure with MeasureQuick | Whether the system is fighting restricted airflow | Flags an airflow fix instead of a part swap or a bigger unit |
| Thermal imaging | Where a wall, ceiling, or floor is losing energy that a thermostat can't show | Points us at insulation or sealing instead of a heating or cooling change |
The Comfort Club is $99 a year, and it covers your seasonal system check-up, priority scheduling, and 15% off every service. Two visits a year keep the small problems small. That's the whole point.
A skipped seasonal check-up is how a small repair turns into a big one. A dirty coil makes your AC grind all summer. A clogged filter starves the whole system.
Novus Mechanical holds a 5.0 average across 44 Google reviews, and Freehold homeowners keep saying the same thing: real answers, not a sales pitch.
I have worked with Novus Mechanical a few times now and recommend them to my neighbors. The owner is responsive, knowledgeable, fair and works clean. I have used Alex to install a completely new HVAC system, to help me figure out why it was so hot in one room in my apt compared to others and to understand my options for adding AC to an old house I am buying. Each time, he was easy to contact, was prompt with his site visits and proposals, was reasonably priced and completed the work when/how he said he would.
Alex and Novus is what I have been looking for! I didn't want someone to come and tell me things that wouldn't solve my problem. I wanted real data and science to show the actual issue. He came and measured the static pressure in both of my furnaces — we planned out how to best address the issues, I got estimates quickly, install shortly after. The work was extremely clean, neat and professional. After all of the work we retested static pressure to show the effectiveness. Novus is the model for every contractor.
We recently had central A/C installed by Novus during a renovation. We are very pleased with the installation and as I'm sure often happens, there were adjustments needed once the system was in and operating. Alex and his team were very responsive and quick to follow-up every time we reached out. I'm more than comfortable recommending Novus to those looking for an outstanding HVAC contractor.
Alex and his team are the best HVAC service we have used, period. Our central AC unit stopped working one night during a heat wave, and they were there right away the next morning to diagnose, and the new compressor was installed 48 hours later. Everything is working perfectly again! They are extremely professional, knowledgeable, and honest. It feels great to know we have someone trustworthy and reliable to call if anything goes wrong in the future!
Novus Mechanical was founded in Freehold in 2016 by Alexander Medvedev, after twenty-plus years in HVAC convinced him the area needed a contractor that diagnoses before it prescribes. Novus is a small family operation: his wife runs the books, the crew is kept small on purpose, because he would rather do ten jobs well than fifty halfway.
Novus Mechanical is based in Freehold, NJ and works throughout Monmouth County. If you're within about 20 minutes of Freehold, we can help.
