Human ingenuity has enabled us to solve every problem we encounter. We can survive in any environment, from deserts to woodlands and more. It continues to serve us today, making life better for all with every new technology. The HVAC industry has certainly enjoyed its fair share of innovations over the years. Our ancestors had to chop wood for heating while we only need to turn up the thermostat and conveniently decide our comfort level. We no longer have to suffer from warm temperatures thanks to air conditioning. In the past decade, several changes have made their mark in HVAC technology that brings tremendous improvement in comfort and energy consumption.

Changes In HVAC Technology

1. Higher HVAC Equipment Efficiency

In the past, only a few households had an HVAC system because of massive costs. Not only was the equipment itself expensive, using them for long periods also cost a fortune. The systems were also quite large and took a considerable amount of space.

There has been a great deal of improvement thanks to the increasing efficiency of modern HVAC equipment. This means air conditioners use less energy to cool down spaces. Owners benefit from reduced energy bills that could save them a significant amount of money. Meanwhile, furnaces use less fuel to heat up homes in the winter. The lower environmental impact is also attractive to eco-conscious consumers.

2. R-22 Refrigerant Phase-Out

R22 Banned

Refrigerants are vital in making cooling systems work. However, the older types were found to be harmful to the ozone layer. This layer absorbs much of the sun’s UV radiation. With ozone depletion, sun exposure poses an increased risk of skin cancer, cataracts, and more. Increased UV radiation also has adverse effects on plants, marine life, and materials.

Manufacturers were encouraged to shift to new formulations with less ecological impact. In 2010, the R22 refrigerant was banned except for the use of existing equipment. By 2020, this was elevated to a total ban such that older systems had to be replaced or retrofitted to make them work with more eco-friendly refrigerants such as R-410a.

3. Smart HVAC Technologies

Every tech company has been pushing for smart homes and introducing their own contributions to the movement. Various appliances can now be connected to the Internet and accessed by smartphones. Owners can check their current status and view their historical statistics. They can also control these objects remotely if they want to. For example, if you forgot to turn off the air conditioner on your way out, then you can do so when you reach the office. This can prevent a lot of energy waste. You could also turn on the cooling system 15 minutes before your projected arrival so you can sit back and relax on a hot summer day.

4. Ductless Heating & Cooling  Systems

A lot of homes use central cooling which requires ducts to move the conditioned air to different rooms. However, there are cases where this configuration may not be practical. For example, those moving to old homes built before central air conditioners became mainstream may not have ducts. Instead of undergoing a massive renovation, they may find that ductless systems are the better option. These are also called mini-split systems or ductless heat pumps because they are composed of an indoor unit and an outdoor unit with each cooling a single room. A ductless heat pump can also provide heat in the winter. This configuration provides better temperature control, noise reduction, and system efficiency.

5. HVAC Zoning Systems

Another popular strategy is to implement HVAC zoning systems for larger homes. This is a good solution if you have a standard HVAC system that cannot provide adequate heating or cooling across the entire structure. Maybe one side gets more sun while the other side is shaded by trees. There will be separate thermostats for each zone so that their temperatures can be monitored and controlled more effectively. Dampers will also be installed across the air ducts. With these changes, the family can feel more comfortable throughout the day. They can also save a lot of money and energy.

6. Sensor-Driven Ventilation

Ventilation often takes a backseat to heating and cooling but it is just as important for overall comfort. In 2016, smart ventilation systems were introduced to the market which allows homeowners to monitor the airflow in every vent. This can be helpful in finding blockages and removing obstructions. These also allow users to turn off the vents that feed air into unoccupied rooms to reduce energy consumption. Certain tasks may be automated based on sensor data.

7. Air Conditioners Have Variable-Speed Compressors

Newer air conditioners feature variable-speed compressors. This technology allows the system to run with less noise, higher energy efficiency, improved temperature management, and better humidity control. It can adapt to changing environmental conditions with ease. When there is a light load, a variable-speed compressor can slow down. When there is a heavy load, it can speed up. There is no starting surge as well so the power supply quality is enhanced. These tend to last longer and provide users with greater comfort. The higher efficiency translates to lower running costs.

Conclusion

The speed of technological progress is truly astounding. Every year brings us more innovations to look forward to. Each of these is designed to solve common issues and make our lives a little better. If you are using an HVAC system that was installed over a decade ago, then you might want to consider getting a replacement soon to take advantage of the improvements mentioned in this list. This is especially relevant if your system is starting to break down frequently. A complete system replacement might end up saving you more money by avoiding costly repairs and reducing your monthly bills.
