AC Installation in Long Valley, NJ

Properly sized central AC for Long Valley’s rolling Morris County terrain — installed by NJ-licensed techs who’ve been at this since 1999.

Long Valley sits at a higher elevation in Washington Township, Morris County, tucked among rolling hills that funnel summer heat in a way flat suburban towns don’t experience. Those conditions — combined with the area’s large colonial and farmhouse-style homes built through the 1970s, 80s, and 90s — make right-sizing a new AC system genuinely important. An undersized unit runs nonstop and never catches up on the hottest July days; an oversized one short-cycles, leaves the air clammy, and wears out early.

Constant Air has been installing central air conditioning and heat-pump systems across Sussex County and into Morris County since 1999. We do a full Manual J load calculation before recommending any equipment, so the system we install actually matches your home’s square footage, insulation, window exposure, and ceiling height — not just a rough guess based on square feet alone.

We carry energy-efficient systems from trusted brands, handle all NJ permits and inspections, and offer Hearth financing to spread the cost. Free in-home estimates make it easy to get a real number before you commit.

Long Valley homeowners have plenty of regional HVAC chains to choose from, but those companies dispatch from central hubs that can be 45 minutes or more away — and their crews rarely know the specific quirks of Washington Township’s older housing stock or its higher-elevation climate. Constant Air is based in Newton, roughly 25 miles north, and we’ve been working in Morris County for years. We know the local permit office, we understand how these homes were built, and we show up on time. Every installation is backed by our NJ HVACR contractor license (#19HC00108700), full insurance, and a 24/7 service line — so if anything needs attention after the install, you’re not chasing a call center. Since 1999, a straight-talking, dependable crew.

Square footage alone isn’t enough — Long Valley homes tend to have higher ceilings, older insulation, and varied window exposures. We run a full Manual J load calculation before recommending any equipment. It takes an hour on-site and costs you nothing; call (973) 948-0680 to schedule a free estimate.

Yes. PSE&G and NJ Clean Energy both offer rebates on qualifying high-efficiency systems, and the federal Inflation Reduction Act tax credit (up to 30% for eligible heat pumps) can further offset costs. We’ll identify every rebate your chosen equipment qualifies for and walk you through the paperwork.

Most residential installations are completed in one day — usually 4 to 8 hours depending on system complexity and whether any ductwork adjustments are needed. We pull the required Washington Township permit in advance so there are no delays. Call (973) 948-0680 to get on the schedule before the busy summer season.
