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.

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

Signs the thermostat needs attention

  • The screen stays blank after you change the batteries.
  • The room does not reach the temperature you set.
  • The heating or cooling does not start when the thermostat calls for it.
  • The thermostat keeps losing its Wi-Fi connection.

A Wi-Fi thermostat lets you see and change the temperature of your home from anywhere, and heat or cool on a schedule that follows your week. SquareHVAC is based in Hillside and serves communities within approximately 30 road miles. We install and set up smart thermostats.

Choosing a thermostat

The right model depends on your system: single-stage, multi-stage, heat pump or zoning change what works. Some models learn your routine and adjust automatically; others rely on the schedule you set. We tell you plainly what fits your system and what each option does.

What the cost depends on

The price depends on the thermostat model, the wiring in your home and whether the system needs an adapter. We assess the system, explain what we found and provide a written quote for approval before work begins.

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

Why people upgrade

  • Remote access. Adjust the temperature from your phone, at work or on vacation.
  • Schedules. Heat and cool when the house needs it, not all day.
  • Maintenance reminders. Notifications when it is time to change the filter or arrange a maintenance visit.
  • Use information. Most apps show runtime history, which helps you spot a system that is working too hard.

What the installation includes

  • Compatibility check. We inspect your existing system to confirm it works with the thermostat you have chosen.
  • Installation. A technician handles the wiring, mounting and configuration.
  • Connection. We connect the thermostat to your home network and set up the manufacturer's app.
  • Walkthrough. We show you how to program the schedule and use the energy features.
  • Support afterwards. If you need help with settings later, call us.

Common questions about Wi-Fi thermostats

Can I install a smart thermostat myself?
Some models are designed for it. If the wiring is straightforward, many homeowners manage; if your system has multiple stages, humidity control or a heat pump, professional installation avoids miswiring.
Does a smart thermostat lower energy use?
It can, by cutting unnecessary runtime when the home is empty or asleep. How much depends on your schedule, the system and how you use the thermostat.
Do I need to be home for the installation?
Yes. Someone needs to let the technician in and show us the existing thermostat and the system it controls.
