New Features You Should Look for in an HVAC System


Like many products and services, high-tech digital features have been utilized in the HVAC industry to provide more efficient and lasting products. With so many new features introduced in recent years, it can be quite a chore to keep up with it all. Read on to see if the following HVAC components spark your high-tech interest!

Wi-Fi Thermostats

The latest thermostat technologies incorporate Wi-Fi and digital features that put home automation at your fingertips. If you are still using a standard digital thermostat or an antique manual box or dial type, take a look at some of the great features Wi-Fi thermostats offer:

  • Control your home’s HVAC system with your smartphone or computer.
  • Program four or more temperature changes to save energy.
  • Receive text or email alerts regarding HVAC maintenance and malfunctions.
  • Control multiple thermostats in a zoning system from one device.
  • Some Wi-Fi thermostats “learn” your preferred temperature and schedule habits and automatically adjust temperature for best energy savings and comfort.
  • Receive automatic software updates.
  • Receive weather reports.

Variable-speed Technology

Variable-speed technology gives you constant comfort by operating at the exact cooling and heating output needed to keep your home comfortable. Conventional air conditioners, heat pumps, and furnaces use fixed-speed blower motors that operate at 100 percent capacity.

Variable-speed blower motors adjust airflow speed up or down as needed in as little as one percent increments. The result is lower energy usage, quieter operation, and exceptional home comfort.

Air conditioner and heat pump compressors are also available with variable-speed digital features — producing less noise, less vibration, and lower energy bills!

Electronic Expansion Valve

The thermostatic expansion valve (TXV or TEV) on your air conditioner or heat pump is the device that controls the amount of refrigerant flowing into the evaporator coil. Many high-efficiency air conditioners and heat pumps use an electronic expansion valve (EEV) for greater accuracy, efficiency, and comfort.
