Heating and cooling service in Edison

Our technicians reach Edison from Scotch Plains in neighboring Union County for furnace, air conditioner, heat pump and ductless work. Our Edison service area page covers plumbing, water heaters and drains in the township; the HVAC services hub lists every heating and cooling service we offer.

Two facts shape most HVAC work in Edison. Edison’s housing skews older: Census data puts the median year of construction at 1974, and about 57 percent of all units were built before 1980. And the township’s permit office lists a new furnace among the projects that require a permit, so a replacement is an inspected job, not a drop-in swap.

Why does an older Edison home’s air conditioner struggle even after a repair?

Usually because the problem is the ductwork or the sizing, not the unit. About seven in ten of Edison’s housing units were built between 1950 and 1989, with the 1980s the single largest decade. A house of that age has probably had at least one air conditioner replaced already. If the ducts are original, they were sized for older equipment: undersized returns starve the blower, leaky trunk lines in an unconditioned attic waste cooled air, and a condenser oversized to make up for weak airflow short-cycles and never dries the air properly.

A proper diagnosis on an older system checks static pressure and airflow, not just the failed part, and if the ductwork is the real limit we say so before you spend money on a compressor. Sometimes the answer is a duct fix; sometimes it is a ductless mini-split for the room the ducts never reached.

Why does a furnace short-cycle or shut off on its limit switch?

Most short-cycling comes down to restricted airflow or a control fault. A clogged filter, a slow blower or a return closed off in a renovation lets the heat exchanger overheat, the high-limit switch opens, and the furnace shuts down until it cools. Repeat that for a season and you risk a cracked heat exchanger. A dirty flame sensor, a failing pressure switch or a thermostat mounted over a supply register can do the same. Each is a straightforward diagnosis if the technician watches a full cycle rather than swapping the first suspect part. Our furnace repair page covers the common faults.

What should I do when the AC quits during a heat wave?

Set the thermostat to off, check the filter and the breaker, and call. Running a unit with a failed capacitor or a frozen indoor coil can turn a small repair into a compressor replacement. If you see ice on the refrigerant lines, switch the fan setting to On so the coil thaws before we arrive. We answer the phone 24 hours a day, including holidays, and emergency heating and cooling calls get a written price before work begins, same as a scheduled visit.

Where should furnace and AC condensate drain?

Condensate from a furnace, air handler or condensing equipment goes to an approved drain or a condensate pump, routed the way the mechanical code and the inspector expect, with a neutralizer for condensing equipment where required. Edison’s wastewater is treated regionally by the Middlesex County Utilities Authority, so the township is on public sewer. Separately, the Township’s Chapter 27 water and sewer code, as posted by the Edison Water Utility, bars sump pumps, floor drains, area drains and roof leaders from the sanitary sewer, so if your mechanical room has a sump or floor drain we check how it is connected before tying anything into it. The Department of Engineering also runs the township’s stormwater program under a state MS4 permit and maintains a Stormwater Control Ordinance and an Illicit Connection Ordinance.

The township’s own preparedness page notes that Edison “should be especially mindful of flooding.” If your mechanical room has ever taken water, ask us about setting new equipment on a raised pad and mounting the outdoor condenser on a stand above grade.

What heating and cooling work do we handle?

We serve the whole township, including Menlo Park, Clara Barton, Oak Tree, Stelton, Bonhamtown, Piscatawaytown and the Raritan Center area.

• AC repair: refrigerant leaks, capacitors, fan motors, frozen coils and compressors.
• AC installation: central systems sized to the house and its ductwork, not by rule of thumb.
• AC maintenance: spring tune-ups that catch weak capacitors and dirty coils before July.
• Furnace repair and furnace maintenance: no-heat calls, ignition faults, heat exchanger inspection.
• Furnace installation: gas, electric and oil-fired replacements, permit and inspection included.
• Heat pumps: cold-climate units that replace both the furnace and the air conditioner.
• Ductless mini-splits: additions, finished attics and rooms the ducts never served.
• Emergency heating and cooling: 24 hours a day, including holidays.

How does a visit work?

Call 908-577-5579 or request service online. A licensed technician from our own crew comes out; we do not subcontract. After diagnosis you get a written price before any work starts, with no hidden fees. If the job needs a permit, we pull it and schedule the township inspection. Financing is available for replacements; see financing.

Getting the permit and inspection in Edison

Construction permits for HVAC, furnace and water heater work in Edison are issued by the Township’s Division of Construction Code Enforcement, part of the Department of Planning & Engineering, at 100 Municipal Boulevard, open Monday through Friday between 8:00 AM and 4:30 PM. The township’s Code Enforcement page lists a new furnace and a new water heater among permit-required projects, and inspections run Monday through Friday between 9 AM and 3 PM; we coordinate the inspection time with you.

One more detail for boiler feed or humidifier work: Edison is split between two water providers, the Township-run Edison Water Utility and Middlesex Water Company, and the township publishes a water provider lookup map so you can check which serves your address. We confirm it on site before connecting to the water supply.
