HVAC features

HVAC features continue to evolve as higher technology infuses cooling and heating systems. Upgrading to new equipment typically brings advancements that improve system performance and efficiency as well as making indoor temperature control more convenient than ever. Even today’s basic standard units include features that weren’t available in older units manufactured just a few years ago. Here’s a brief overview of new HVAC features that may not have been available the last time you upgraded.

  • Higher SEER performance. SEER (Seasonal Energy Efficiency Ratio) is the metric that expresses central air-conditioner efficiency. In the year 2000, the required SEER was just 10. Today, minimum SEER ratings are 13 or 14, depending on the locale. At the upper end, new high-efficiency air conditioners offer SEER efficiency rated higher than 20 for significantly lower cooling costs without sacrificing comfort, making it one of the most valuable HVAC features.
  • Variable air circulation. Traditionally, HVAC blowers in homes only operated in on/off mode. When the system cycled on, circulating air volume was 100%. When the unit turned off, air circulation was zero. Cooling and heating comfort also alternated noticeably. Now, efficient, intelligent variable-speed blowers circulate conditioned air nearly constantly while continuously fine-tuning the volume of air to meet temperature requirements.
  • Zoning systems. Temperature preferences often differ from room to room. However, a single HVAC system typically only provides the same temperature in every room. Zoning systems, however, can support a variety of temperatures in multiple rooms with just a single AC or furnace. Automated dampers inside ductwork are opened and closed by a computer linked to individual thermostats, managing heating and cooled airflow and maintaining different temperatures in different rooms.
  • Smarter thermostats. Unlike the “dumb” manual thermostats of yesteryear, today’s intelligent thermostats automatically execute programmed temperature changes inside the house scheduled in advance. Internet connectivity also adds the ability to alter temperature settings as well as monitor the indoor environment in your home from anywhere in the world.
