The Next Evolution of Home Energy Savings


Single-Speed vs. Multispeed (and why it matters)

 Meritage Homes is paving the way as the first national builder to install highly-efficient multispeed Carrier® HVAC systems as a standard in new communities and in select homes in existing communities after April 1.


For a better picture, imagine you’re driving a vehicle and you floor the accelerator. You’re asking the engine to run at full speed. It’s loud, every part of the engine is moving at full capacity and you’re using more gas. That’s similar to how a single-speed HVAC system functions. The thermostat calls for heating or cooling and the system kicks on — at full speed.

Multispeed HVAC systems work a lot like a car adjusting its speed — the car may go 60 mph on the highway, but only 35 mph in a neighborhood. And at lower speeds, it makes less noise, uses less fuel and puts less wear and tear on the system.

So how does all of this help our homeowners?

Let's dig a little deeper into the day-to-day benefits of a superior HVAC system.

  • Better HealthAir Quality

    Greater Humidity Control & Better Air Quality

    About 70% more humidity is removed in a multispeed HVAC than single-stage units. The system in Meritage homes can now eliminate 121 pints of moisture per day, or about 29 2-liters of water — nearly twice as much as the single-speed. Additionally, because the HVAC is designed to run longer, it will more often cycle and filter air, potentially improving indoor air quality.

  • Real ComfortComfort

    More Comfort

    Less humidity, of course, creates a more comfortable environment for homeowners. Longer run times at lower speeds increase dehumidification capability and provide for more even cooling — with less humidity, rooms just feel cooler, even at higher temperatures. Plus, when the multispeed HVAC operates at a lower speed, it makes less noise — creating quieter at-home time for families.

  • More SavingsSavings

    Energy Efficiency = Savings

    The multispeed units know when it’s time to work hard and when it’s better to relax. In extreme temperatures, they’ll run on high. But when it’s milder, they’ll cruise on low which ultimately saves you money on energy use. Plus, the actual equipment is 10% to 15% more efficient than a typical system because homeowners get more cold or warm air per kW when it’s running at full speed, according toCR Herro, Vice President of Innovation at Meritage Homes. “Through the combination of all our building practices and the new HVAC system in our Meritage homes, the total heating and cooling cost can be reduced over 50%,” says Herro.


    The evolution of energy-efficient homes

    The homebuilding industry has been looking for opportunities to create energy efficiencies across the board. “And I think the industry has evolved so that the lights, appliances, heating and cooling system, and the water heater are much more efficient than they were 10 years ago,” says Herro. “And then the next evolution is to really be smart, not just about the machine, but how the machine runs.”

    Meritage Homes continues to be the leader in innovation by incorporating several energy-efficient features in its homes that pull double duty by keeping your home healthy while running smoothly. MERV 13 air filters, sealed ducts and spray foam insulation help keep dust and allergens out, while the multispeed HVAC system helps maintain high air quality by circulating clean and filtering air more frequently, all while saving energy and costs. Together, they work as a system to keep your Meritage home functioning more efficiently, improving the health and comfort for you and your family.
