Get Better Efficiency, More Consistent Heating and Cooling with Two-stage and Multi-stage HVAC Equipment

As we do our new HVAC installations and HVAC upgrades, we often recommend homeowners install a two-stage or multi-stage system for residential heating and cooling.

Traditional single-stage HVAC systems operate as on or off and in general, so indoor air temperatures fluctuate more than with a modern two-stage system. Multi-stage HVAC equipment (two stages or more) switches between low and high stage operation depending on conditions.

What is a two-stage HVAC system?

Two-stage HVAC systems have a low setting and a high setting. They run much of the time on the low setting and switch to the high setting as needed. The low stage (used for moderate temperatures) usually operates at between 60% and 70% of full capacity and the high stage (for hotter or colder days) runs at full 100% output. The result is more consistent heating and cooling with improved unit and energy efficiency.

We install Carrier’s two-stage heat pumps, furnaces, and air conditioning systems. While multi-stage units have a higher initial cost, they can be a worthwhile long-term investment thanks to improved comfort and lower energy bills.

Benefits of multi-stage HVAC equipment

• Reduces energy consumption – the lower capacity setting uses less energy
• Lowers energy bills – fewer temperature fluctuations, less energy consumption results in lower utility costs
• Less wear and tear on the system – fewer stops and starts means less effort to heat and cool the home, with less stress on the compressor and other HVAC components
• Increased comfort thanks to more stable temperatures with fewer hot and cold spots in the house
• Improves indoor air quality – more continuous air movement leads to better air filtration
• Operates more quietly than traditional systems – the lower speed run times are less noisy
• Delivers better humidity control during the summer months – extended, lower-speed run times enable the system to remove more moisture from the air

Variable speed for precise cooling

Many two-stage systems include variable speed blower fans. These kick up energy efficiency a notch by matching airflow to comfort demands in real time. These units have “smart” electronics that monitor conditions and automatically select the best stage for comfort and efficiency. Variable speed heat pumps and central air conditioners with Greenspeed Intelligence can adjust their speed and output to match the cooling demands of your home, with the ability to adjust down to 1% increments, delivering precise temperature control.
