Why Choose a Variable Speed Air Conditioner Or Heat Pump?
By Travis Baugh
Are you considering a new air conditioner and encountering the term "variable speed technology"? Understanding this feature can help you make an informed decision. Variable speed air conditioners and variable speed heat pumps offer substantial benefits, including enhanced energy efficiency, superior comfort, and improved humidity control.
Variable-speed technology allows an air conditioner or heat pump to modulate its speed and capacity based on your home's cooling needs. This capability not only increases energy efficiency and can help reduce costs but also helps enhance overall comfort and humidity control.
With a Carrier variable speed air conditioner, you can look forward to the potential for lower heating and cooling energy bills, superior humidity control, and a quieter operation that brings peace of mind.
What is Variable Speed HVAC Technology?
Variable speed HVAC technology is a groundbrewww.carrier.com/residential/en/us/products/air-conditioners/aking feature in modern air conditioners and heat pumps, designed to provide enhanced comfort and energy efficiency. Unlike traditional air conditioners and heat pumps that operate at a fixed speed, variables peed units can adjust their speed and output to match the cooling demands of your home. With speeds adjusting down to 1% increments!
This technology employs advanced sensors and algorithms to continuously monitor indoor temperature and humidity levels. Based on this data, the air conditioner or heat pump can automatically adjust its speed and airflow, maintaining a consistent and comfortable environment.
A significant advantage of variable speed HVAC technology is precise temperature control. Traditional air conditioners and heat pumps might cause temperature fluctuations by turning on and off, think like a light switch, to maintain the desired temperature. In contrast, variable speed air conditioner units can fine-tune their operation, similar to lights with dimming features, for steady and even cooling.
Variable Speed Air Conditioners and Variable Speed Heat Pumps
- Energy savings
- Consistent comfort
- Enhanced humidity control
1. Energy Savings
Most of the higher efficiency heating and cooling systems today achieve their ratings with variable-speed technology. These systems can help save money on your heating and cooling bills, and some may even qualify for local utility company rebates. Here’s how:
- Variable speed units can modulate their speed and energy usage based on current conditions. This means they can operate at lower speeds when cooling demands are lower, thus using less electricity, resulting in significant energy savings.
- Single-speed systems actually use more energy turning on and off more often, running at full capacity when they are on regardless of the temperature.
By running at lower speeds during periods of reduced cooling demand, variable speed HVAC systems consume less energy compared to traditional units that operate at full capacity constantly. This can help reduce your heating and cooling bill and also your carbon footprint.
2. Consistent Comfort
Going back to how variable-speed technology works, the longer heating or cooling cycles help keep the air in your home consistently closer to the temperature set on your thermostat. This results in more even, consistent comfort, with fewer hot spots and cold spots in the house.
In comparison, single-speed systems turn on at full blast to reach the right temperature, then shut off when the temperature is met. When the temperature drops, the system turns on again and the cycle continues with up and down temperature swings.
3. Enhanced Humidity Control
In the summertime, humid, sticky air can sometimes make you more uncomfortable than hot temperatures. While all central air conditioners remove a little humidity from indoor air during the cooling process, some do a better job than others.
Variable-speed systems are much better at humidity control than standard, single-speed systems. Because they are operating for longer periods of time, they can remove more moisture from the air, so you FEEL more comfortable. You may even find yourself placing your set point higher than you would with a single-stage unit.
Carrier takes it even further with Ideal Humidity SystemTM technology, a function that manipulates speed settings and cycle times to squeeze even more of the uncomfortable moisture from indoor air.
4. Improved Sound Levels
The noise level of your air conditioner significantly impacts your living environment. Carrier's variable speed air conditioners and humps are designed to operate quietly, ensuring a peaceful atmosphere in your home.
Unlike traditional air conditioners and heat pumps with fixed speeds, variable speed units offer precise control over the indoor fan motor's speed when paired with a communicated indoor. This allows the unit to adjust its output based on your home's cooling needs, resulting in more efficient and quieter operation.

FREQUENTLY ASKED QUESTIONS ABOUT VARIABLE SPEED AIR CONDITIONERS
Variable speed air conditioners and heat pumps can offer enhanced energy efficiency, lower operating costs, and improved indoor comfort by maintaining consistent temperatures and better humidity control. They operate more quietly and reduce wear and tear on the system, potentially extending its lifespan. Whether they are “worth it” is up to the individual and their level of comfort.
While variable speed air handlers offer several advantages, variable speed air handlers are generally more expensive to purchase and install compared to single-speed models. Although they have a higher upfront cost, the long-term savings and comfort benefits may outweigh the initial investment.
Variable speed in an air conditioner/heat pump refers to the ability of the compressor and fan motor to operate at different speeds, adjusting airflow and cooling capacity based on the cooling/heating needs of the space. Unlike traditional AC/HP units that operate at a fixed speed, variable speed models can run at lower speeds during mild weather, increasing efficiency and maintaining consistent indoor comfort.
No, variable speed air conditioners/heat pumps do not run all the time. They adjust their speed and operation based on the cooling/heating demands of the space. During mild weather or when the cooling/heating load is low, variable speed AC/HPs can operate at lower speeds or cycle on and off as needed to maintain the desired temperature..
Yes, a variable speed air conditioner/heat pump typically requires a compatible thermostats that can communicate with and control its variable speed capabilities effectively in order to use all features and functionality. Standard thermostats may not be capable of fully optimizing the performance of a variable speed AC/HP, such as adjusting fan speeds and operation modes based on the cooling requirements of the space. Always check with your dealer to make sure you get a thermostat that fully utilizes your variable speed system’s capabilities.
