What is an Inverter Air Conditioner System?

Inverter air conditioners use less energy and save money on utility bills

Unmatched Efficiency & Consistent Comfort

Typical standard air conditioners are put to the test when extreme temperatures hit. Their all or nothing approach cycles the system and your home’s comfort. With an inverter air conditioner system, there is a consistent, leveled output keeping you comfortable. Inverter air conditioners have less variation in their output, delivering consistent temperatures and indoor comfort.

The Advantages of Inverter Air Conditioning Technology

As indoor temperatures rise and you hear your air conditioner turn on, you look forward to the initial blast of cool air. There is a certain comfort that comes with feeling the air moving. But after your thermostat turns it off, the indoor temperature begins to rise again and there is a staleness to the air.

An inverter air conditioner doesn’t cycle on and off costing you more on your energy bills.

The inverter air conditioner system is equipped with controls that proactively manages the variable speed compressor motor that handles your AC unit’s cooling capabilities. This balanced operation limits wasted energy that non-inverter air conditioners expend when they have to “fire up” the motor to begin a cycle. Installing an inverter air conditioner unit will help you save energy while providing a consistent desired room temperature and comfort.

What is an Inverter Air Conditioner System?

Inverter or variable capacity air conditioners regulate the frequency of voltage to the compressor motor. The inverter air conditioner system controls the output of your HVAC system by controlling the current to your compressor in small increments both up and down.

By running your air conditioner consistently but at lower power, your system will be more energy-efficient. With constantly fluctuating temperatures in the Knoxville area, an inverter air conditioner system can better manage your indoor comfort.

Inverter Air Conditioner vs Non-Inverter Air Conditioner

Energy efficiency is the main difference between conventional and inverter air conditioning systems. Inverter technology allows the ability to manage the current that your air conditioner on-demand and is what gives it the edge over a non-inverter air conditioner making it the best air conditioner.

A conventional single-stage compressor motor will turn 100% on or off when the desired temperature is reached. They are either running at 100% or not at all. Some non-inverter units use two-stage compressors that run at the lower power most of the time to keep more consistent room temperatures. But they operate at full speed when more power is needed.

Comparing Air Conditioner Compressor Types

All air conditioners use a compressor to provide the flow of refrigerant. There are three common compressor types found in most residential AC systems. A Non-inverter air conditioner uses either a single-stage or two-stage compressor.

When the thermostat calls for cooling, each compressor motor uses a different amount of power to generate the necessary cold air to reach your desired temperature settings. Inverter-driven AC compressors run at the minimum needed, requiring less power consumption and providing more consistent temperatures.

Single-Stage AC Compressors

Single-stage air conditioners run at either 0% or 100% full capacity and have shorter but more frequent cycles. There will be noticable temperature swings. When off, the indoor air temperature will rise until the unit turns on. After the desired temperature is reached, the thermostat will turn off the AC unit.

It is the least efficient cooling method because the unit is either on or off which uses more electricity. The cost effectiveness of a single-stage central air conditioner is preferred by some homeowners.

Two-Stage AC Compressors

Two-stage air conditioner units have longer and less frequent cycles than the single-stage unit. They run at either 65% (stage one) or 100% capacity (stage two). You will sometimes notice room temperature swings but less extreme than a single-stage air conditioner unit. A two-stage unit will run at lower speed most of the time to keep more consistent temperatures, and only use full speed in periods of high demand.

Inverter AC Compressors

Long and slow cycles are the key to reducing energy consumption. Inverter air conditioners actively regulate the speed of the motor. This allows the unit to run between 35 and 120% capacity. During operation, the output varies only slightly. Consistent cooling power with virtually no temperature change is the result.

Energy consumption will decrease because the unit is not wasting energy to keep you comfortable. The upfront cost of an inverter driven air conditioner is recouped in monthly utility bill savings.

Inverter driven reverse cycle heating and cooling

Known as a heat pump, a reverse cycle unit can cool and heat your home or business. An inverter-driven heat pump is a complete solution to your indoor comfort. These systems provide versatile heating and cooling capabilities.

These units are perfect for East Tennessee where the outdoor temperature can change considerably day after day.

Ductless Inverter AC System

The most common application for inverter technology in air conditioning is the ductless mini-split. The ductless mini-split is a versatile inverter driven heating and cooling unit. The compact outdoor unit can be mounted on walls and rooftops as well as on the ground.

The indoor units come in a variety of styles that suit almost any rooms decor. Typically, they service a single zone or room. They can also be set up for multi-zone with multiple indoor units on the same outdoor unit.

Ducted Inverter Air Conditioner

Central Inverter Air Conditioner

All major HVAC brands have a high efficiency, inverter driven line of heating and air units. Typically 18 and 20 SEER, these units are top of the line and fully loaded with the best new technology. They have tremendous advantages over the non-inverter air conditioner.

Mini-splits no longer

Mini-splits have always had a ducted option. But the design still targeted single rooms or zones. However, inverter ACs are now being made as direct replacement for traditional, central, non inverter units. They make use of existing duct work, thermostat wiring, thermostats, and linesets. They come in all residential capacities, 2-5 tons.

The indoor units are sized to fit where the non-inverter air handlers are installed. This gives the homeowner a tremendous opportunity to take full advantage of the energy-efficient inverter technology with running exposed linesets or air handlers.

The rarely mentioned benefit of inverter air conditioning

We’ve covered many of the benefits of having an inverter air conditioner. The one that gets rarely mentioned is humidity control. One of the major functions of air conditioners is removing moisture from the indoor air. This only happens when the unit is running.

Have you ever woken in the middle of the night during the summer and thought, “It’s warm in here?” You get up expecting there to be something wrong with your AC and find that it’s working fine. The warm, uncomfortable feeling is because humidity is building up in your home. It’s dark and the temperature in your home is low. So, your thermostat isn’t telling your air conditioner to start.

As we mentioned, your non-inverter air conditioner is either fully on or fully off.

Your inverter air conditioner runs for much longer periods of time. This keeps humidity levels low throughout your home. Humidity control means better overall comfort. 70 degrees feels like a real 70 degrees. You’re not forced to set your thermostat a few degrees lower to get that 70 degree feeling.

Choosing the Right Air Conditioning System

Deciding on the right air conditioner for your home or business can be tough. There are many factors to consider. The square footage of your home and the heating and cooling needed to meet that need is where the decision making process starts.

The HVAC contractor that you choose should perform an audit of your property. They should take note of where your doors and windows are, and the presence adequate insulation. If you have any questions about selecting a new air conditioning system, we’re here to help.

If you choose an inverter air conditioner, you’ll need an experienced and licensed HVAC installer. Most of the major brands will not sell inverters to HVAC companies without their first attending a special training.

There are a lot of good reasons to choose an inverter AC system. However, the benefits won’t be realized if not properly sized and installed. The HVAC technicians at Blue Water will help you make the right decision for your needs.
