What is the Difference Between a Standard HVAC Unit vs. Inverter HVAC Unit?

For most people, when the time has come to change their HVAC system, knowing what the best new system to install in their home can be daunting. Most people are not overly concerned with the inner workings of every HVAC system—they may need an entire course just to understand the differences between one system and another. What most people’s main concerns are three things: Is it going to be costly? Will it be able to properly heat and cool my home? Is it going to be loud and noisy?


In this post, we are going to address why an inverter system is superior to the standard HVAC system based on the three things most homeowners care about. But we’re also going to dig a little deeper to show you the intricate intricacies of how the inverter system works in a superior way.


Imagine that you’re driving down a highway using cruise control. You see cars in the distance going a bit slower, so you’re able to adjust your speed to match or dial down delicately. This is why highway miles are much more efficient in terms of car and gas. Now imagine that you’re driving down a road with 10 stop signs. At each stop sign, you come to a complete stop and then start the car back up, only to come to a stop again. Most people understand how inefficient this is in terms of gas and car lifespan. This difference in efficiency is the main reason why the inverter HVAC system is superior to the standard HVAC system.


Compressor Speed


A standard HVAC system has a compressor that is either fully running or fully stopped. It runs at a fixed speed. The inverter system has a variable speed operation. This allows the compressor to operate at different speeds based on the heating and cooling demand.


Precise Temperature


All HVAC systems are designed to heat or cool a home to its desired temperature. However, the standard HVAC system completely shuts off once it reaches its desired temperature, whereas the inverter system slows the compressor speed to simply maintain the exact temperature. When the home’s temperature fluctuates throughout the day, the standard unit will have to turn back on fully to reach the desired temperature once again.


Noise Level


The inverter system generally has a quieter operation because it does not turn on to the fullest extent that a standard HVAC unit does. The variable speed of the compressor allows for a smoother operation altogether.


Lifespan


The constant cycle of turning off and back on again throughout the lifespan of a standard HVAC unit tends to break down over time. The variable speed of the compressor in the inverter system experiences much less wear and tear and generally leads to a longer lifespan for your HVAC system.


The inverter HVAC system is built for maximum comfort and efficiency, quieter operation, and a longer lifespan. It is only a matter of time before the inverter system is the dominant HVAC system in our Southeast Tennessee region. Much like how highway miles are more efficient than city miles, the inverter system is much more efficient than your standard system. The growth of inverter systems is inevitable.
