Preparing For a Future Without Any R-22

R-22 bannedThe EPA’s release of the R-22 phaseout schedule has provided a better idea of how fast R-22 refrigerant will be eliminated. Building owners and managers can now plan for it over the next few years. A big part of that preparation is education.

R-22 will be gone soon so now is the time to make decisions about your HVAC equipment. In Sacramento, 70-80% of commercial buildings still have R-22 systems in operation. Whats your plan?

A Cool Idea – Electricity Free Air Conditioning

New materials may change the way temperatures are regulated


Cooper Oates Air Conditioning HVAC, Mechanical Contractors, Electricity

A Stanford University research team has invented a way for buildings to dump their heat without the needs for pumps, fans or compressors. This idea, described in a recent issue of Nature, is simple and provocative – radiate the heat back into space. The materials used for this process are still in the prototype stage and in the end would probably not eliminate all of a building’s cooling needs. The idea could be the start of something really cool.  Read More Here.


HVAC Retirement – To plan or not to plan

The end is coming! The question is, is it better to plan for HVAC replacement or endure the disruption when it occurs.

Old HVAC Ready for Retirement Replacing or upgrading an HVAC unit is never an easy decision, unless that decision has already been made for you due to the unit failing. Many building owners and managers are reactive when it comes to their HVAC systems. Something changes (no air, no cool, no warm etc…) then action is taken to correct the failure or replace the unrepairable unit. Even with diligent and meticulous maintenance HVAC has a finite lifespan and it will fail eventually. The real decision with managing the HVAC assets is will you manage them or will they manage you.

We suggest that you take control and manage these remarkable and quite vital assets. Whether the units are old and running on borrowed time due to the increasing shortage of R-22 refrigerant, you are looking to increase the buildings value and marketability or just want to save energy, taking control will pay off in many ways. Have a plan in place that allows you to be pro-active about your replacement strategy and that fits you budget. Thinking strategically about your HVAC assets is proving to be more economical over the long run than reacting to emergencies.

COAC can provide you with information and expert advice that will guide you through your decision process. Detailed unit evaluations, pre & post energy use modeling, maintenance and replacement planning and financing are just some of the ways we can assist you in taking control. To plan or not to plan, it’s up to you.
