The ingenuity humans possess allows us to solve the problems that come our way. It helps us survive in different environments, such as deserts, woodlands, among others. It continues to help us to this day, making life better with new technology. The heating and cooling industry has had its share of innovations through the years. For example, our ancestors used to light wood for heating. However, we only need to adjust our thermostat settings to achieve our preferred comfort level. We also don’t need to endure hot temperatures with the help of our air conditioners. The past decade has brought many changes to HVAC technology, ensuring tremendous improvement in our homes’ comfort and energy efficiency.

Changes In HVAC Technology

Some of the changes in HVAC technology that we have seen in recent years include:

1. Higher HVAC Equipment Efficiency

In the past, there used to be only a few houses fitted with an HVAC unit because of its massive costs. Aside from the unit being expensive, using them for long hours would rack up high energy bills. HVAC equipment was also very bulky, taking up a huge chunk of space.

Many improvements have been made such as the efficiency of modern HVAC systems. This means less energy is consumed to cool homes and offices. Since less energy is used, you will have significantly lower energy bills, and you get to save money in the long run. Furnaces also utilize less fuel to heat homes in the winter. This also means that there is less environmental impact, which is a feature that eco-conscious consumers like.

2. R-22 Refrigerant Phase-Out

Refrigerants are an essential component needed for cooling units to work as expected. Older types utilize a refrigerant that destroys the ozone layer, which absorbs the sun’s harmful UV radiation. Keep in mind that exposure to the sun can run an increased risk of cataracts, skin cancer, and other health issues. It can also lead to adverse effects on marine life, plants, and various materials. As a result, manufacturers have shifted into using new refrigerants that have a less ecological impact. The R-22 refrigerant was banned from being used except in existing air conditioners in 2010. This was elevated to a total ban in 2020 which means that older units with a coolant leak will need to be replaced or retrofitted to ensure they operate using eco-friendly refrigerants like R-410a.

3. Smart HVAC Technologies

All tech companies have been pushing to have smart homes by introducing innovations from their companies. Different appliances can now be connected to the internet, so you can access them via your smartphones. This way, they can check the appliance’s status and even look into the historical statistics. The appliances can also be controlled remotely. For instance, in the summer, you might have forgotten to turn up your thermostat’s temperature setting before going out. You can do it in your office using your smartphone, so you don’t air-condition an empty house and waste energy. You can even turn it back on before you get home so you can relax in a cool house after being out all day.

4. Ductless Heating & Cooling Systems

Many homes use central cooling systems that need ductwork to ensure that conditioned air reaches various rooms throughout your house. However, it might not be as practical to have this type of system in some situations. You might have recently moved into an old home that is not fitted with ducts. If this is the case, consider installing a ductless system instead, so you don’t need to have a massive renovation done at home. A mini-split or a ductless heat pump consists of an indoor air handler and an outdoor condenser that can cool a single zone or room. Ductless heat pumps can also keep your home warm during the winter. A ductless HVAC system provides high system efficiency, better temperature control, and noise reduction to your home.

5. HVAC Zoning Systems

Larger homes typically implement HVAC zoning systems nowadays. This is a good strategy to utilize if you use a standard HVAC system that cannot adequately cool or heat your home in its entirety. One side could be getting more sun while trees shade the other. HVAC zoning means that each zone has its own thermostats so you can monitor and control the temperatures effectively. The air ducts can also be fitted with dampers. These changes mean that your household will be more comfortable and consume less energy. Therefore, you’ll also save more money.

6. Sensor-Driven Ventilation

Ventilation is often neglected when it comes to home heating and cooling. However, it is also an essential factor in achieving comfort. Smart ventilation systems were introduced in 2016. This innovation allowed homeowners to monitor the flow of air in all vents throughout their homes. This makes finding and removing blockages easier. It also allows you to switch off the vents in unoccupied rooms to save energy. Some tasks can also be automated depending on the sensor data.

7. Air Conditioners Have Variable-Speed Compressors

Newer AC models have variable-speed compressors. This means that your system operates with less noise, enhanced temperature management, improved humidity control, and higher energy efficiency. It adapts to the changing environmental conditions easily. A light load means that a variable-speed compressor slows down, while a heavy load can speed it up. A starting surge won’t happen, so the power supply quality improves. This helps extend your unit’s lifespan as well as provide your home with greater comfort. It is also highly efficient, so you will have lower energy costs.


The technological progress in the HVAC industry over the years is truly amazing. Each year brings innovations that have been designed to solve common problems. These make our lives easier and more comfortable as well. If you have an HVAC system installed ten years ago, consider getting a replacement to receive the benefits that the improvements in this list can bring into your home. This is especially so if your HVAC unit has been needing frequent repairs recently. Replacing your system might help save you more money as you avoid the need for costly repairs. There will be a significant reduction in your monthly energy bills as well.

Ductless air conditioning systems do not need ducts like central, or forced-air air conditioners. They work the same way central ACs do, cooling an area by pulling in warm air, eliminating the water and heat from the air, and disposing of the moisture and heat outside. As they do not utilize ducts, ductless air conditioners deliver the cold air directly into the targeted area. On the other hand, central air conditioners use ductwork to distribute the cold air throughout different areas in your home. However, many homeowners still wonder “How do ductless air conditioners work?”.

How Do Ductless Air Conditioners Work?

Read on to find out everything you need to know about ductless air conditioners.

Components Of A Ductless AC Unit

A ductless air conditioner has three main parts. These are:

Single-Zone Mini-Split Vs. Multi-Zone Ductless Setups

Ductless air conditioners are an effective way to cool a single room/zone and multi-zones. Therefore, you can install this type of cooling system in various settings depending on your needs.

Single-Zone Ductless Mini-Split

This mini-split consists of one evaporator or blower unit and an outdoor condenser. It is typically used to cool a single room or zone. If you have ample outdoor space to accommodate several condensers, you can set up more ductless air conditioners that will work together to keep your entire house cool. This allows you to customize the temperatures in each room depending on your needs. It also means that if one system breaks down, the rest remains unaffected and will continue to work as they should. Typically, 8 indoor units can attach to one condenser.

Multi-Zone Ductless HVAC

This type of mini-split comes in two configurations. The first one has multiple indoor units connected to a single outdoor condenser (as mentioned above). Each indoor evaporator or blower unit has a thermostat. All units are switched simultaneously when cooling is needed. This makes it a more cost-effective option. It is the ideal setup for buildings wherein each zone or room has different cooling needs.

The second configuration has detached compressor circuits connected with each evaporator unit. This way, you have a customizable system that can achieve true HVAC zoning. The occupants can control the temperature settings in each zone according to their preferences and needs.

Do Ductless Air Conditioners Have Adequate Cooling Power?

Individual units might seem small, but that is only because they are meant to cool a single room. This allows for easier cooling. However, you need to ensure that the BTU capacity of the system matches the room size so that the unit works effectively. The general rule of thumb is that bigger rooms need higher BTU ratings. Consult a reliable HVAC technician to find the cooling load for your specific needs. They will calculate it using various factors to see what will work best for you.

If it is too small for the area it is cooling, the system will strain to maintain the set temperature. The components will wear out faster, and your unit will need repairs often. On the other hand, short cycling will happen if you have a system that is too large. Frequently turning on and off will lead to a shortened lifespan. Some of the common sizes a ductless air conditioner comes in are:

Some of the pros and cons of having a ductless cooling system are listed below:

Pros Of Ductless Cooling Systems

Cons Of Ductless Air Conditioning Systems

Ductless systems are typically more expensive at the onset. However, they are more energy-efficient and customizable. Keep in mind that if you do not have any ducts, the cost of a central AC installation will significantly increase because you need to have ductwork installed as well. This will make central air conditioners costlier than a similarly sized ductless unit.

Central air conditioners can be hidden in the attic, closer, or basement, while ductless air conditioners are usually mounted on the ceiling, walls, or floor. Therefore, ductless units are more difficult to hide and can affect your aesthetic. However, they are less intrusive and sleeker than a window air conditioner.


Ductless air conditioning systems are highly versatile, customizable, and energy-efficient. They also remove the need to install a network of ducts to distribute conditioned air, meaning they are generally less costly to install and maintain than a central air conditioner.
