The HVAC industry has been transitioning to variable-speed HVAC systems for the past decade. Although prices on these new variable-speed systems may be steep, there are several benefits that make this system more efficient and beneficial than older models. This article will focus on the top 6 reasons to choose a variable-speed HVAC system, how these units work, and why it is important to have them professionally installed.
How Does a Variable Speed HVAC System Work?
The primary objective of your HVAC system is to keep the temperature in your home at a comfortable level. This is done by cycling on and off, depending on the temperature readings detected by sensors inside your home. Older models used to have just one sensor located in an inconspicuous location within the building.
Variable-speed systems are equipped with several sensors that are put at different locations throughout the house. This allows for more accurate monitoring of indoor temperatures, which results in more efficient operation of this equipment.
Another benefit is that unit fan speeds are capable of adjusting based on internal heat levels. When it detects hot air within the building, it will turn up its fan speed to compensate for this excess heat. Conversely, if it detects cold air, the fan speed will slow down to compensate for the lack of heat.
What Makes a Variable-Speed HVAC System More Efficient?
Fan motors on variable-speed systems are more efficient than those found in older models. This is because they use permanent split capacitor (PSC) motors rather than old-style universal motors. PSCs offer several benefits over their predecessors, such as:
– Lower noise levels: PSCs create less noise than universal motors, and new system designs allow for even better sound reduction.
– Less vibration: Since fan blades on PSC fans are suspended, this reduces vibrations caused by the spinning of these fans.
Another energy-efficient feature is variable-frequency drives (VFD). VFDs adjust the frequency of power supplied to a motor so that it can run at different speeds without getting damaged. This allows for more precise control over indoor temperatures based on environmental conditions.
How Does a Variable Speed HVAC System Save Money?
Improved energy efficiency is one of the reasons why consumers choose to invest in a variable speed HVAC system, but it’s certainly the only benefit offered by these units. They use less energy than older models, which results in lower monthly utility bills.
Top 6 Reasons to Choose a Variable Speed HVAC System
Quieter Operation
One of the main reasons to switch to a variable speed HVAC system is the reduction in noise levels caused by these units. PSC motors are specifically designed with quiet operation in mind, which means lower noise during fan operation.
In addition, systems that use VFDs produce less vibration because of their blades being suspended rather than spinning horizontally or vertically. As a result, you will notice that variable-speed air conditioners and furnaces tend to be much quieter than other types of HVAC equipment.
Cost Efficiency
As previously mentioned, variable-speed HVAC systems use less energy than older models to maintain preferred indoor temperatures. They also recover more quickly after drastic temperature changes and operate at lower speeds when environmental conditions warrant it. If you’re looking for ways to reduce your energy costs, these are all great reasons to consider having a variable-speed HVAC system installed in your home.
Precise Temperature Control
Variable-speed systems have the ability to monitor multiple indoor sensors and adjust unit fan speeds accordingly to maintain preferred temperatures. If it detects that the air is too cold, the fan will increase its speed to compensate for this lack of heat. If it’s too warm, the fan will slow down because there isn’t enough hot air present to be effectively circulated throughout your home. This means you can avoid being subjected to drastic spikes or drops in temperature caused by older models switching on and off repeatedly over short periods of time.
Comfortable Air Quality
Some have shown that variable-speed systems are better at maintaining healthy indoor air than older systems. That’s because they constantly monitor environmental conditions and adjust unit fan speeds accordingly to maintain clean air quality within your home. When the air quality is poor, the system will increase its fan speed to compensate for this excess dust and debris in the air. If it detects low temperatures, it also has the ability to heat or cool incoming fresh air until proper temperatures are reached before circulating good air throughout your building.
Greater Energy Efficiency
All of these benefits can add up when you’re looking for ways to reduce energy consumption in your home. Variable-speed systems use less energy than older models, which results in lower monthly utility bills during operation. Furthermore, they recover faster after drastic temperature changes between seasons which also results in significant savings. The bottom line is that you will see a reduction in your energy bill if you switch to a variable-speed HVAC system.
Decrease Carbon Footprint
These systems also decrease your carbon footprint by using less energy than older models. This reduction in energy consumption reduces the number of greenhouse gasses emitted into the atmosphere, which contributes to global climate change.
Variable-speed HVAC systems have been shown to improve the overall comfort level within a home because they use precise amounts of energy depending on environmental conditions. They are very cost-efficient and allow homeowners to better regulate their indoor temperatures without making them uncomfortable. Furthermore, you will reduce your carbon footprint significantly by switching to a variable-speed air conditioner or furnace for heating and cooling needs.
Professional Installation
