Air Conditioning

Central Air Conditioning Installation and Replacement in North Jersey

Replacing central air is one of the larger purchases a homeowner makes, and the brand on the box matters less than how the system is sized, matched and installed. Master's Plumbing installs central air and heat pump systems across Union, Essex, Bergen, Passaic, Hudson and Morris counties, and we do it the long way: a load calculation, matched equipment, a correctly sized line set, a clean condensate path, a permit and a final inspection.

We install all major brands and quote every job by the job, with financing available. When your current system still has life in it, we tell you that too.

When replacement makes more sense than another repair

  • The system is out of warranty and needs a compressor, coil or major refrigerant repair
  • It uses R-22 refrigerant, which is no longer produced
  • It still cools but runs almost nonstop on hot days and never catches up
  • Repairs have become a yearly event
  • Some rooms are comfortable and others never are, and the ductwork checks out
  • Electric bills climb every summer with the same thermostat setting
  • You are adding a finished attic, addition or second story the current unit cannot handle

What a proper installation includes

  • Load calculation and sizing

    We measure the house, insulation, windows, orientation and ductwork rather than copying the tonnage off the old nameplate. Oversized systems short-cycle and leave the house clammy. Undersized ones never catch up.

  • SEER2 efficiency options

    SEER2 is the current efficiency rating for central air. We explain the practical difference between standard and higher-efficiency tiers in operating cost, comfort and price, and let you choose.

  • Matched systems

    The outdoor condenser, the indoor evaporator coil and the air handler or furnace blower are selected as a matched set so the system performs at its rated efficiency.

  • Line set and refrigerant piping

    We replace or flush the copper line set, size it for the new equipment, braze with nitrogen flowing, pressure test and pull a deep vacuum before charging.

  • Condensate management

    A properly pitched drain, a trap, a float safety switch and a secondary pan wherever the air handler sits above finished space.

  • Electrical and controls

    The correct breaker and disconnect, a new whip, surge protection if you want it, and a thermostat that matches what the equipment can do.

  • Permits and inspection

    We pull the required permits with your town and schedule the inspection. It is not optional, and it protects you when you sell the house.

  • Removal and disposal

    The old condenser, coil and refrigerant are removed and disposed of properly. Refrigerant is recovered, never vented.

From estimate to first cool day

  1. 1

    In-home estimate

    We look at the existing equipment, ductwork, electrical service and the house itself, then give you options in writing with firm prices.

  2. 2

    Choose your system

    Standard or higher efficiency, central air or heat pump, with financing available if you want to spread the cost. No pressure.

  3. 3

    Installation day

    Most straightforward replacements are finished in a day. We protect the floors, remove the old equipment, set the new condenser on a level pad, install the coil and line set, run the electrical and drain, and start the system.

  4. 4

    Commissioning and inspection

    We verify the charge, airflow and temperature split, walk you through the thermostat and register the manufacturer warranty. The town inspection follows.

  • “5 stars all around. Came out as quickly as possible and it was late night. Great customer service. And fixed my issue with tips for the future so that I can maintain my plumbing. Thanks!”

  • “If you need work done and don't want to waste money on the same repair call Moe. Truly wished I found the company sooner, it would've saved me a lot of headache and expenses. When I called and explained my situation, without seeing the repair he already knew what needed to be done. He visited the same day and shortly after fixed a damaged pipe that could've taken out the lower half of my home. On site, Moe thoroughly explained the repairs needed at a reasonable cost. Polite, professional and truly knowledgeable.”

  • “Master's was a godsend. We called late at night when our basement started flooding out of nowhere and Moe immediately came over. He was able to fix our issue and walked us through what caused it, what to expect, how to handle it if it happens again, and long term fix options. He was outstanding and I highly recommend Moe and Master's!”

FAQ

AC Replacement & Installation questions, answered

What size air conditioner do I need?
The only honest answer comes from a load calculation on your house. Square footage alone is not enough. Insulation, window area, sun exposure and duct condition all change the number. Bigger is not better; an oversized unit cools fast, shuts off before it removes humidity, and leaves the house cold and damp.
What is SEER2?
It is the efficiency rating for central air conditioners, measured under a newer test procedure than the old SEER rating. A higher number means less electricity for the same cooling. Whether the higher tier pays back depends on how much you run the system, and we lay that out for you.
Do I need to replace the furnace or air handler too?
Not always. The indoor coil almost always gets replaced to match the new condenser. If the furnace blower is old or incompatible with the new equipment, replacing it at the same time is often cheaper than doing it separately later.
Do you offer financing?
Yes. Financing is available on new system installations. Ask when you call and we will explain the options.
Do I need a permit for a new air conditioner?
Yes. New Jersey towns require permits and an inspection for HVAC replacement. We handle the paperwork and scheduling.
