How many microns in size is the COVID-19 virus?

The COVID-19 virus is approximately 0.125 Micron or 125 nanometers in diameter. (Source: National Library of Medicine)
However, it often travels in biological aerosols from coughing and sneezing which range in size from 0.5-3 Micron.
Face Masks of the HVAC realm are the “new normal”.  The fact that viruses can be airborne, higher MERV filters can trap them.

Sharp Cooling Tower Cleaning

Normally we clean Cooling Towers during low ambient conditions in the fall and spring time.  As soon as this project was approved, our Team was able to start Cooling Tower Cleaning during the first 2020 heat wave in SoCal. This required precise execution with the Hospital engineering staff and our Technician staff to keep Central Plant Chillers online while we took down three Cooling Towers at a time. The Cooling Towers were extremely dirty and could have caused the Central Plant Chillers to surge and possibly lock out on Condenser Water.

What happens to Big Box Retail Stores when they Close? You recycle!

We are helping U-Haul recycle old Kmart buildings in Southern California into storage facilities for consumers. This process includes converting the old inefficient HVAC systems into efficient HVAC systems. Storage temperatures in specialties storage need to be maintain and done efficiently. This takes the knowledge of RAM Engineering to covert and retrofit systems to meet the needs of U-Haul. Gas flows, water flows, air flows and electrical flows must be in balance and this takes Physics. This takes the knowledgeable technicians at RAM HVAC & Engineering!

Coils and Corrosive Sea Air


Did you know that in Southern California coils are usually the first item to fail due to the corrosive nature of Sea Air? Ram Air Engineering can tackle diagnosing and replacing any size coil in Southern California. Make sure to have a team of experts like Ram Air Engineering replace your coil vs. waiting for a leaky coil too! A loss of refrigerants is expensive and if you wait for a coil to become leaky it could cost you. When should I replace my coils? Ram Air Engineering suggests that you replace your coils every 10-15 years.

The more unusual the better….

1991 Bixby Knolls tower LB. 12 stories up we lifted a section of chiller out of penthouse. With 2” to spare! We have a history of tough jobs! The more unusual the better….

San Diego Commercial HVAC Company Installs Pelican Wireless Thermostat Systems at the Boys and Girls Clubs of San Dieguito

Having recently completed installation of the Pelican Wireless Thermostat systems at two San Diego locations of the Boys and Girls Club of San Dieguito, San Diego commercial HVAC company, RAM Air Engineering is excited to work with their new client.


According to Boys and Girls Club of San Dieguito COO, Andy Brosche, RAM Air’s HVAC technicians were very thorough in their installation of the new Pelican Wireless Thermostat systems and he is very pleased with the results. Not only that, he was impressed with the newfound ability to monitor the building’s HVAC by controlling the package units from his tablet or phone. With the addition of remote statistics and historical graphical data, Andy and his team are now able to control temperatures at the space instead restricted to the location of the main thermostat as well as view the past energy use of each unit. Additionally for such a technical wireless HVAC thermostat system, our San Diego Commercial HVAC technicians were able to complete training on the use of the Pelican Wireless Thermostat system in less than 20 minutes.

Another great feature of installing a commercial Pelican Wireless Thermostat system is participation in RAM Air Engineering’s new maintenance program to reduce filter changes from quarterly to tri-yearly, which ultimately, reduces filter waste and cost of program. To participate in this maintenance program all the client needs is upgraded Tridec 3 ply filters and Pelican controls which is good for package units from 3 ton to 100 ton boxcar type units. With the Pelican Wireless Thermostats in place our HVAC technicians at RAM Air Engineering can monitor notifications pushed from Pelican and respond to problems before they become major issues.
