AC Installation in Franklin, NJ

New AC installation in Franklin, NJ — properly sized systems for Sussex County’s former zinc-mining borough, installed by a Newton crew that has served this area since 1999.

Franklin Borough sits in a valley in the heart of Sussex County, roughly six miles south of Newton along Route 23. The borough is compact but densely built — its housing stock reflects more than a century of working-class construction tied to the old zinc mining industry that defined the town for most of the twentieth century. What that means for air conditioning is a neighborhood of older homes: prewar two-stories, mid-century single-family houses, and solid older structures with limited attic clearance, minimal wall insulation, and ductwork — where it exists at all — that was designed around a central furnace, not cooling. Installing a new AC system in that kind of housing takes a trained eye, not a standard package quote.

Constant Air Service has been installing central air conditioning, high-efficiency heat pumps, and ductless mini-split systems throughout Sussex County since 1999. We work out of Newton, which puts us about a ten-minute drive from Franklin — close enough to give you a same-day estimate and fast install scheduling, without the travel fees a regional chain pads into every job. Every installation we do starts with a full Manual J load calculation: we measure your home’s square footage, ceiling height, insulation levels, window orientation, and actual air-sealing conditions before we recommend a single piece of equipment. That calculation is what prevents an oversized system from short-cycling and leaving your home damp all summer.

We manage the entire process from start to finish: free in-home estimate, permit filing with Franklin Borough, equipment delivery and installation, system start-up testing, and a full homeowner walkthrough before we leave. Hearth financing is available for households that prefer to spread the investment, and our 24/7 emergency availability means you have a direct line to us if anything needs attention after installation day.

A regional HVAC company dispatching from Morris County will send someone unfamiliar with Franklin’s dense older neighborhoods — the prewar two-stories near the Franklin Mineral Museum area, the mid-century ranch homes on the borough’s side streets, and the older houses with tight crawlspaces and undersized duct chases that make every installation a puzzle. Constant Air Service is based in Newton, roughly ten minutes north on Route 23, and our crews have been working in Franklin and across Sussex County since 1999. We know what AC installation looks like in a 1940s two-story with a floor-furnace past, and we know when a ductless mini-split is a smarter call than trying to run new sheet metal through an uninsulated wall. We are licensed under NJ HVACR #19HC00108700, fully insured, and available 24/7 for emergencies. Every job starts with a free in-home estimate, includes proper permit filing, and ends with your system running and verified before we pull out of the driveway.

We run a full Manual J load calculation before we recommend anything — measuring your home’s square footage, insulation, window area, ceiling heights, and air-sealing conditions. Franklin’s older housing stock often has minimal insulation and duct systems that were sized only for heating, which changes equipment selection significantly. Call (973) 948-0680 to schedule your free in-home estimate and we’ll walk through the numbers with you.

Yes. Ductless mini-split systems are an excellent fit for Franklin’s older homes where running new duct through prewar framing and tight wall cavities isn’t practical. We handle the complete installation — indoor wall units, outdoor condenser, line sets, and all electrical connections — with minimal disruption to finished walls and ceilings. Call (973) 948-0680 and we’ll assess your floor plan and recommend the right configuration.

A standard central air installation in a Sussex County home generally runs $4,500–$9,500 depending on system size, efficiency rating, and whether existing ductwork needs modification or replacement. Ductless mini-splits vary based on the number of zones needed. We provide a written, itemized quote at no cost before any work begins, and Hearth financing is available to spread payments over time. Call (973) 948-0680 to set up a free estimate.

Yes. Constant Air files the required mechanical permit with Franklin Borough, coordinates the inspection schedule, and handles all paperwork — you don’t need to track anything yourself. Permit coordination is part of our standard installation process at no additional charge to the homeowner. We do not begin work without the proper permits in place, and we see the inspection through to final approval.
