What should you do next?

Not sure if you need service now or can wait? Use these signs to choose a practical next step. Talking through what your system is doing does not commit you to an appointment.

See smoke, flames or signs of a fire? Leave the building, stay out and call 911. If there is no fire and it is safe to use the controls, switch the system off and call SquareHVAC.

Emergency service is available 24/7, including Sundays.

Plan an AC maintenance visit

Quick checks before you call

  • Check the thermostat: is it set to heat or cool, and is the set point where you expect?
  • Check the filter: a clogged filter limits airflow. Replace it if it is visibly dirty.
  • Check the power: look at the breaker and the equipment switch near the unit.
  • Check the airflow: hold a hand at a supply register and feel whether air is moving.
  • Check the outdoor unit: clear leaves and debris from around it.

Signs to call us about

When to replace an air conditioner

  • the air conditioner is old and a main part has failed, such as the compressor or the indoor coil
  • it needs a repair every summer
  • it uses R-22, an older refrigerant that is no longer produced
  • some rooms never get cool, even when the system works
  • you are replacing the furnace anyway. The two share the blower and the ducts, so it can make sense to do both together

When the old air conditioner cannot keep up — or a major part has failed on a system near the end of its life — a new system is the better path. SquareHVAC is based in Hillside and serves communities within approximately 30 road miles. We install central air conditioners, ductless mini-splits and heat pumps, sized to the home and installed to the manufacturer’s specifications. Serving homeowners and businesses since 2009.

What the cost depends on

An installation price depends on the system chosen, the home’s ductwork and electrical connections, access to the equipment, and whether anything worn needs replacing at the same time. We assess the system, explain what we found and provide a written quote for approval before work begins, with parts and labor listed separately.

The written quote

We explain what we found and what it costs, in writing, with parts and labor listed separately. You review it; you decide. Work only begins once you approve.

All services

What the installation service includes

  • System selection. We assess the home's size, layout, insulation and ductwork, and recommend a central air, ductless mini-split or heat pump system.
  • The installation. Technicians install the system per the manufacturer's guidelines.
  • Testing before we leave. We verify airflow, refrigerant charge and thermostat operation, and show you how the thermostat works.
  • Aftercare. A maintenance visit once a year keeps the new system working as installed.

What happens on installation day

  1. Step 1

    Old unit out

    We protect the floors and remove the old unit.

  2. Step 2

    Lines and connections

    We check the pad outside, the copper lines, the drain and the electrical connection, and replace what is worn.

  3. Step 3

    New system in

    We install the indoor coil and the outdoor unit.

  4. Step 4

    Refrigerant charge

    We charge the system with refrigerant to the maker's instructions.

  5. Step 5

    Test and handover

    We run it, check the temperatures and the airflow, and show you the thermostat. A system that also needs new ducts takes longer, and we tell you the expected time in the written quote, before you decide.

Common questions about air conditioning installation

Can I install an air conditioner myself?
No. Installation involves pressurized refrigerant lines and electrical connections. It is regulated work for a reason, and mistakes are expensive to find afterwards.
Which brands do you install?
We install systems of all major brands. What we recommend depends on the home's size, layout and ductwork, and we provide a written quote before work begins.
Can you help with rebates?
We can help you identify utility or manufacturer rebates that are available when you replace equipment. Programs and eligibility change, so we check what applies at the time of your quote.
