Cooling a Montclair Victorian is an art.We brought the arithmetic.
Twelve-foot ceilings, plaster walls with no cavity to speak of, third-floor bedrooms baking under a slate roof. These houses are beautiful and genuinely hard to cool, and most of the systems that fail in them were sized by someone matching the old label rather than measuring the house.

What we see here
Why Montclair houses defeat ordinary sizing
Four things about this housing stock change the answer, and a quote that ignores them is a quote for a different house.
- Volume, not floor area
- High ceilings change everything A 2,400 square foot Victorian with twelve-foot ceilings holds far more air than a 2,400 square foot ranch. Sizing off square footage alone systematically gets these houses wrong, which is why we calculate volume and load rather than reading the old nameplate.
- Plaster and lath
- Little insulation, real thermal mass Solid walls behave differently from a modern insulated cavity. They hold heat into the evening and they resist quick temperature swings, which affects both the equipment size and how the system should be staged.
- Third floors
- Under a dark roof, at the end of the run The top floor is where nearly every complaint starts. It's the hottest space and the furthest point from the air handler. Adding tonnage rarely fixes it; fixing the return path, adding a zone, or putting a dedicated system up there usually does.
- Retrofit ductwork
- Squeezed through whatever was available Ducts in these houses went in decades after the house did, routed through closets and chases wherever there was room. Undersized returns are extremely common, and a bigger condenser feeding a starved system just runs less efficiently and no cooler.
This is why we measure before quoting and why the quote is itemised. An oversized system short-cycles, never pulls the humidity out, and leaves a house that reads cold and feels clammy — which in a plaster house is exactly the wrong outcome.
Repair or replace
We'll tell you the truth, even when it costs us the sale
Not every struggling system needs replacing. If a repair buys you more good summers for less money, that's the recommendation you'll get, in writing.
Replacement usually wins when
12–15 yrs+
and the repair quote is more than about a third of what a new system costs. At that point you're spending real money to extend something already near the end of its life.
- It runs on R-22 — phased out, expensive, harder to source each year
- Two or more service calls in the same season
- Bills climbing summer on summer with no change in how you use it
- Rooms that never cool, which is usually sizing or ductwork rather than the box outside
Repair is the right call when
Under 10 yrs
and it's a single component — a capacitor, a contactor, a fan motor. Those are repairs at any age, and anyone quoting a whole system off the back of one isn't being straight with you.
- A capacitor is $185–$285, not a reason to replace anything
- One failure, not a pattern of them
- Bills are steady and the house cools evenly
- We'd genuinely rather you called us again in eight years
No starting-at games
What's in the quote
One fixed price, itemised, before anything begins. The number you sign is the number you pay.
- Sizing
- Manual J on your house Volume, insulation, window area and orientation, ductwork. Getting this right is half the job in a Montclair house and it's the half most quotes skip entirely.
- Permits
- Filed and inspected Required township permits filed, inspection scheduled, installed to current code including electrical disconnects, refrigerant line standards and condensate handling.
- Removal
- Old system taken away Old condenser and coil removed, refrigerant recovered and disposed of legally. Floors and stairs protected — in these houses that matters — area cleaned, and the new system tested with you before we leave.
- Warranty
- Registered on the day Factory registration inside the 60-day window, which is what actually starts the 10-year parts coverage. Miss it and the coverage quietly isn't there when you need it.
Installed pricing for a typical 2,000 sq ft North Jersey home runs $6,995–$9,995 for a 14.3 SEER2 single-stage, $9,995–$13,995 for a 15–16 SEER2 two-stage, and $12,995–$18,995 for a 17–20 SEER2 variable-speed system. Larger Montclair houses and anything with a third-floor zone typically sit in the upper part of those ranges. Ductwork, where it genuinely needs doing, adds $2,500–$6,000. Financing is 0% APR for 12 months on jobs over $1,500.
How the job goes
Four steps, no mystery
We look at what you have
Including whether it's actually finished. Plenty of the systems we're called to replace have a few more summers in them, and we say so.
Manual J, then a fixed quote
Measured from the house rather than matched to the old box. Itemised, in writing, and it doesn't move afterwards.
Installed, usually in a day
Most replacements on existing ductwork run 7am to 4pm. Stairs and floors covered, old equipment leaves with us.
Permit, inspection, warranty
Filed same day, inspection coordinated, warranty registered. You get the paperwork rather than a promise about it.
A/C replacement in Montclair: the questions we get
My third floor never cools. Do I need a bigger system?
Usually not, and this is the single most common wrong answer in this town. A starved return, a long duct run and a dark roof will beat any amount of extra tonnage. What usually works is fixing the return path, adding a zone, or putting a dedicated system on that floor. We measure airflow before recommending anything, because guessing here is expensive.
What does a replacement cost?
For a typical 2,000 sq ft home: $6,995–$9,995 for a 14.3 SEER2 single-stage, $9,995–$13,995 for a 15–16 SEER2 two-stage, and $12,995–$18,995 for a 17–20 SEER2 variable-speed. Larger houses and multi-zone work sit higher. Ductwork adds $2,500–$6,000 where it's genuinely needed. Every quote is fixed and itemised before anything starts.
Can you cool an old house without tearing it apart?
Usually, yes. Existing ductwork is reused wherever it's adequate, and where it isn't there are routes that don't involve opening plaster across the house. If your job genuinely does need invasive work, you'll hear that at the quote stage rather than mid-install with the walls already open.
How long will I be without cooling?
One day for most replacements on existing ductwork, roughly 7am to 4pm. If new ductwork or a new zone is involved it's two to three days. We tell you which one you're in before you commit, not on the morning of.
Should I do the furnace at the same time?
Often it makes sense. A modern condenser needs a matched indoor coil to reach its rated efficiency, doing both in one visit saves roughly $800 to $1,500 in labour against two separate jobs, and matched-system rebates are usually better. If the furnace is over fifteen it's likely to follow the A/C anyway.
What about rebates and financing?
Federal credit up to $600 on qualifying 16+ SEER2 equipment and up to $2,000 on a qualifying heat pump. NJ Clean Energy pays $300 to $1,500, and the utilities add $100 to $500. Financing is 0% APR for 12 months on jobs over $1,500, with longer fixed-APR terms available. We file the rebate paperwork as part of the job.
Getting to you
Essex County
Everything runs out of 2 John St in Haledon — dispatch, parts and the fleet bay.
Replacement is scheduled work rather than emergency work, so the ETA above matters less than the survey date — and we'll give you a real one. Permitted work in Montclair is filed with the township as part of the job, with the inspection coordinated by us rather than left to you.
