At Bruce’s Air Conditioning & Heating, we’re proud of our reputation as a leader in commercial and residential HVAC services for nearly 50 years. Of course, much has changed since we first opened our doors. There have been tremendous technical advances in air conditioning. Here are just a few of the amazing innovations that improve the comfort of homes and businesses.

1970

The first ductless air conditioning systems are invented, serving as an alternative to portable air conditioners attached to windows. These enable air conditioners to be placed in locations other than windows.

1975

The US government begins their investment in HVAC research and innovation. Propelled by the energy crisis of the ‘70s, this leads to the first national standards for HVAC equipment.

1978

The heat pump is invented. The air-to-air heat pump is used in both heating and air conditioning systems.

1987

The UN Montreal Protocol is created to protect the ozone layer. The international treaty was signed by participating countries to begin the phasing out of use of ozone depleting chemicals, including the ubiquitous coolant – Freon.

1987

The Seasonal Energy Efficient Ration (SEER) measurement of energy efficiency is rolled out for HVAC systems. This is the first national standard for efficiency and is still used today.

1994

Freon is officially linked to ozone depletion, kicking off a ban around the world. The US government launches millions of dollars to ramp up research on improvements to air conditioning and refrigeration.

1996

All HVAC manufacturers in the US are required to switch to the environmentally-friendly coolant R134a.

2000

R410a is introduced as a more environmentally-friendly coolant.

2005

The combination of technology and improved coolants have measurably improved HVAC system efficiency by more than 30 percent.

2007

Nearly 90 percent of all American homes now have air conditioning. Compare this with just 10 percent in 1965.

2010

HVAC is connected to the Internet of Things (IoT). HVAC systems with sensors can now be controlled by internet-enabled devices.

2011

The Nest thermostat is introduced, enabling consumers to monitor their energy usage and adjust their HVAC systems from their smart phones. Nest is rapidly acquired by Google.

2015

The US Department of Energy starts funding into research of non-vapor compression technologies for HVAC systems. This could mean a reduction of energy use by more than 50 percent.

2020

The innovation continues in the HVAC industry. From greater integration with other smart home technologies to leveraging artificial intelligence to optimize energy efficiency, the advancements are nothing short of amazing.
