HVAC Then & Now: How Has It Improved Through the Years?

The HVAC industry has undoubtedly changed significantly over the years. From the invention of the first contemporary air conditioning in 1902 to the current innovative technology, HVAC systems have advanced quite a bit. 

In the early 20th century, people began using air conditioning in homes and businesses due to its ability to regulate temperature and humidity. And this was revolutionary for those living in hot climates, allowing them to stay cool even during the hottest summer days. Over time, HVAC systems became more efficient and durable, lasting twice as long as before while consuming far less energy.

Address Your AC Stressors

Several factors can stress your air conditioner, hindering its optimal performance. Therefore, getting the most from your AC requires addressing its stressors. That way, you can ensure your air conditioner serves you better and longer. Also, you can lower your monthly energy bills and maintain healthier, cleaner indoor air. Here are the primary AC stressors to address and ensure your AC system’s optimal performance and longevity.

  1. Start with regular preventive maintenance. During this process, experts remove debris and contaminants from the unit, clean the coils, and check the parts for wear and tear.
  2. Be sure your AC unit has adequate airflow. Remove any obstacles blocking the free circulation of air through ducts and vents.
  3. Change your AC filter often to keep dirt and dust from building up in the system’s components. A clean filter will allow for better airflow, which helps reduce stress on the air conditioner motor and other system parts.
  4. Ensure the correct functioning of your thermostat so that it can accurately read temperatures inside the home or office building with the AC system.
  5. Keep your compressor in good shape by ensuring it is adequately lubricated and has the proper refrigerant level.
  6. Check all electrical components associated with the air conditioner, such as wiring and circuit boards, for signs of damage or wear and tear that can cause overheating and other problems.
  7. Please ensure there are no leaks in the system that can lead to inefficient performance, wasted energy, and high utility bills.

Giving your AC unit the necessary TLC will help keep it running efficiently, improve its performance, reduce stress levels, and extend its lifespan. If you need help giving your AC unit the TLC, contact a professional HVAC contractor for expert advice, maintenance, and repair services.

HVAC Industry Has Come a Long Way

Today’s HVAC systems are sleeker, quieter, and more intelligent than ever. For instance, smart thermostats can adjust temperatures automatically based on user preferences or conditions outside, enabling homeowners to save on energy costs. Additionally, many modern HVAC systems incorporate air filtration to improve indoor air quality. 

Moreover, the emergence of HVAC professionals with certifications in handling intricate repairs and servicing has also contributed to improving the industry’s standards. In particular, these technicians ensure that all system components operate correctly and efficiently, increasing their longevity and performance. 

As technology evolves, so does the HVAC industry. Experts are releasing more efficient designs every year. Undoubtedly, HVAC technology will continue to advance to meet consumer needs and future environmental goals. 

The HVAC Industry's Journey

The HVAC industry’s journey began in 1902 with the introduction of the first contemporary air conditioning system. Since then, the industry has gone through several transformations and advancements as follows: 

  • Basic necessity: Only the wealthy could access air conditioning for years. Before the invention of window units in the 1930s, air conditioners cost between $10,000 and $50,000, translating to $120,000 to $600,000 today. However, AC systems became more accessible and affordable in the 1950s. As of 2007, 86% of homes in America had air conditioners.
  • Sleek and quiet systems: First AC systems were pretty contraption. Their piping and venting required large rooms. However, they eventually shrunk, with modern AC units being smaller and quieter, particularly the ductless models.
  • Smarter systems: Older AC systems were energy-intensive. However, contemporary models are more efficient. These systems use innovations like smart thermostats for automation, lowering their energy consumption.
  • Environmentally friendly systems: Initially, people ignored the impacts of air conditioners on the environment. However, modern systems minimize carbon footprints while protecting the ozone layer. One step that reduced the AC systems’ impact on the environment was the phase-out of the R-22 refrigerant. Today, people go for greener methods for heating and cooling their homes.
  • More heating and cooling products: There was a time when the industry had a one-size-fits-all product. However, the industry has hundreds of models and brands of air conditioners. Thus, property owners have more heating and cooling products to consider when shopping. 

The HVAC industry has improved tremendously. With every technological advancement, consumers can benefit from better savings and energy-efficiency products that lower their heating and cooling costs. 

However, you need help choosing the right product for your specific needs and budget. That’s where the expertise of HVAC specialists comes in. So ensure you get a qualified technician to help you choose, install, repair, service, maintain, or replace your system.
