Variable Speed Compressors & Energy Efficiency For Your Home
All about Variable Speed Compressors and how they improve your home’s efficiency
Choosing A Variable Speed Compressor
John Jones A/C, Heating & Refrigeration specializes in high-efficiency comfort systems. Did you know upgrading your A/C unit and furnace to a variable speed heat pump can save you money on your energy bills each month? The savings can be almost enough to pay for the new system, over time. Variable speed technology works differently than standard A/C units, with results that provide incomparable comfort and efficiency.
How they work:
AccuComfort™ Heat Pumps avoid the peaks and valleys of conventional systems by varying its output in 1/10 of 1% increments in order to stay within a 1/2 degree of its set temperature. The result is ultimate comfort and a quietly powerful way to satisfy your idea of home sweet home.
Accu-Comfort from American Standard is a true variable speed product with a compressor that can ramp between 400 and 6000 RPM with an inverter drive. The outdoor section communicates with the indoor section and the controller to give a very well tailored comfort solution and dehumidification without spikes and hard starts as conventional systems experience, always missing their mark and either over cooling or under dehumidifying.
The Accu-Comfort system totally eliminates the need for a dehumidifier and allows the user to set desired humidity levels which are easily achieved without overcooling the home. The result is a very crisp, cool, dry living space which is very efficient and totally controllable from a smart phone or other wireless device.
The Department of Energy states that over half of energy usage in homes is attributed towards heating and cooling the home. Variable Speed Heat Pumps greatly reduce your home’s energy consumption by not cycling off completely but instead keeping the temperature within 1 degree of your desired temperature. Since the system doesn’t completely power off and then back on, your home stays more comfortable and your energy bills get lower.
From the graphic below, you can see that it takes more than 8X the energy for a system to start and stop. Most systems can start/ stop up to 72 times per day during the hottest and coldest days of North Alabama. That’s a lot of wasted energy!
We’ve outlined three reasons why switching to a variable speed compressor is a great decision for your home and your wallet:
Reason 1: Energy Efficiency
A variable speed compressor, also known as an inverter-driven or inverter compressor, allows your HVAC system to use only the amount of energy needed to deliver the cooling capacity you need.
For instance, if it is 95 degrees outside, your air conditioner may need to run at near full capacity to handle the load, but when it is only 80 degrees, the load is lower, so the speed can change (hence variable speed). By only using the amount of power and energy you need, you’ll consume less energy, which saves money and helps protect the environment at the same time.
Reason # 2: Comfort
Besides energy savings, another benefit of a variable speed compressor is that you won’t feel uncomfortable blasts of hot or cold air when the system comes on. Instead, the amount of conditioned air that enters your home comes in incremental doses.
Reason # 3: Air Quality and Humidity Control
Variable-speed heating and cooling usually runs for longer periods of time, but at a lower setting. Less energy and force means quieter operation and a better airflow. It’s cheaper to keep the system on at low levels than turning it on and off more frequently. The highest energy usage from an HVAC system comes from constantly powering on and off, as shown in the graphic above.
The longer, better airflow cycles also improve humidification levels, air filtration, and decreases the chance of duct leaks and comfort problems.
