HVAC Tips: Opening Indoor Spaces Safely as COVID Restrictions Ease

COVID cases are falling, but the pandemic is far from over. As vaccination rates rise and COVID cases fall, how can you get your business ready to open its doors safely? Both the Centers for Disease Control and Prevention (CDC) and the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Epidemic Task Force recommend a layered approach.

Make Sure Idle Systems are In Good Working Order

If your system has been shut down for an extended length of time, follow standard practices for new construction startup to ensure proper system operation and safety. This is especially important for water systems and features such as humidifiers/dehumidifiers, cooling towers, and refrigeration units due to the risk for Legionnaire’s bacteria. This task is easily managed by requesting a maintenance service call from your local commercial HVAC mechanical services provider.

Exchange Indoor Air with Fresh Outdoor Air as Much as Possible

Because the COVID virus spreads more readily indoors than outdoors, where virus concentration is diluted, enhanced ventilation is crucial. This can be accomplished in a number of ways:

• Upgrading your building with added ventilation
  Talk to your commercial HVAC contractors about ways to modify your system to improve ventilation, such as an exhaust, supply, or heat recovery ventilation system.
• Using natural ventilation
  When weather permits, opening doors and windows, except when doing so, poses a health risk due to allergen or environmental contaminant exposure, reduces airborne viral concentration.
• Use fans
  Fans improve circulation when windows/doors are open. Place fans in windows, exhausting air outdoors. Do NOT blow potentially contaminated air towards people.
• Decrease occupancy levels
  If outdoor ventilation cannot be increased.
• Pre and/or post flush with outdoor air
  Run HVAC at maximum outside airflow 2 hours before and after occupancy to enhance air cleaning within the system.

Improve HVAC Air Filtration

Talk to your commercial HVAC service company to determine the highest level of filtration your commercial HVAC unit can manage without affecting system performance and lifespan. ASHRAE recommends a true HEPA filter with a rating of 13 or higher. The higher the number, the more particles a filter can remove from the air.

Consider Adding an Air Purifier with UV Light 

Incorporating an air purifier with an ultraviolet germicidal light into your commercial HVAC system offers another layer of protection, trapping and killing airborne contaminants. These systems are more effective than portable models, cleansing air throughout the building.

Enforce the Use of Masks and Social Distancing

Maintain the CDC’s recommended 6-foot social distancing measures whenever possible and continue wearing masks until most of the population has been vaccinated and herd immunity has been reached. While progress in our fight to control the virus continues, we are not out of the woods yet.

Every building faces unique COVID reduction challenges. Learn ways to effectively decrease the COVID viral load in your building through improved ventilation and filtration with help from H & H Commercial Services. Contact us to schedule a consultation today.

Commercial HVAC Preventative Maintenance Checklist

Unsure of how to take care of your commercial HVAC system from season to season? Our commercial heating and air conditioning repair team has you covered, with the details on essential seasonal maintenance tasks. This spring, ensure your commercial AC is in tip-top shape before summer weather extremes push the limits of your system.

Spring Commercial HVAC Maintenance Checklist

Our commercial HVAC mechanical services recommend regularly performing these tasks:

• Change AC filters 
  Regularly changing air filters is one of the most important maintenance tasks. Dirt buildup in filters forces your system to work harder, negatively impacting your system’s performance and lifespan. Dirty filters also distribute dirt through essential AC components and your business, affecting indoor air quality.
• Clean coils and fan
  Fifty percent of summer AC failures are the result of improper cleaning. Evaporator coils, condenser coils, and fan blades clogged with layers of dust, dirt, mold, and plant debris drag down the performance of your system, making it difficult for your commercial HVAC system to maintain temperature.
• Maintain drain lines
  Drain lines must be regularly cleaned according to the manufacturer’s instructions to prevent clogs from dirt, minerals, mold, and mildew that can lead to leaks and water damage inside your building.
• Inspect electrical components
  It’s best to regularly inspect the wiring in your commercial HVAC system for loose connection, shorts, and visible damage from animals that may have sought shelter in your system over the winter.
• Check refrigerant levels
  A system with low refrigerant levels will have difficulty maintaining temperature. If levels are low, this indicates a leak.
• Verify thermostat function
  Your thermostat serves as the brain of your system. If it is not reading the temperature accurately or engaging the system as it should, it could lead to an uncomfortable indoor climate and wasted energy. A minor investment in upgrading to a new smart thermostat offers superior comfort and savings.
• Check for adequate airflow
  Check for furnishings blocking vents and registers and ensure airflow is evenly distributed through all vents and registers.

Well Maintained Commercial HVAC Systems Save Energy

Regularly performing these basic maintenance tasks will keep your system running at peak performance – however, our commercial HVAC contractors want you to know this list is not all-inclusive. Rooftop units, heat pumps, VRF systems, chiller/cooling towers, water-cooled systems, dehumidifiers, and more all have unique care requirements. The type, age, location, and usage of your system may also affect maintenance frequency. A customized commercial HVAC maintenance plan is best to ensure peak performance, keep energy costs in check, and prolong the life of your system.

Make sure your commercial HVAC system gets the timely, expert care it needs. Contact H & H Commercial Services to schedule a full system inspection or to learn more about our commercial maintenance plans today.

How to Avoid Unfortunate Commercial HVAC Accidents

Experiencing a fire is traumatic. Most unfortunate is that, most home and business owners think they are unlikely to suffer such an incident, believing they are less at risk than those they see in the news. This false sense of security, called optimism bias, leads many to neglect procedures that could safeguard them against a similar experience. Commercial HVAC contractors know dangerous HVAC fires are among these preventable issues, and they are avoidable with simple maintenance measures.

Basic Steps You Can Take to Prevent HVAC Fires

Making yourself aware of common HVAC related fire hazards is essential to protect your business. Keep a watchful eye out for these common causes:

• HVAC electrical problems
  Electrical issues are the leading cause of HVAC fires. Commercial heating and air conditioning repair technicians see a lot of them, particularly in aging, poorly maintained systems. Making yourself aware of the condition of your system through regular HVAC maintenance can help you prevent a dangerous situation. If it’s been a while since your system has been serviced, don’t wait. A professional checkup could thwart a potential disaster – or at the very least, major repair expenses.
• Overuse in weather extremes
  Heating and air conditioning systems draw a lot of current. In heat waves and cold snaps, when HVAC constantly runs for many hours or days at a time, it is possible for the motor to overheat, resulting in a fire.
• Crowded heating and air equipment
  Heating and cooling equipment located in cramped quarters,  crowded by cleaning chemicals and boxes – or worse – used as shelving to store these items, poses a serious fire risk. Keeping your unit clear and unobstructed ensures efficient operation and reduces fire risk.
• Improper installation
  Installation mistakes such as poorly fitted connections can go undetected for years until other forces like weather or an earthquake worsen the issue. Regular inspections by our commercial HVAC mechanical services contractors ensure all fittings, gas, and electrical lines to your unit are properly secure and in good working order.
• Combustion-related concerns
  Combustion equipment such as gas furnaces poses a host of fire hazards, particularly when maintenance is neglected. In addition to all of the above concerns, faulty gas connections, improper fuel pressure (both high and low), and leaking fuel lines could result in a fire. Poorly maintained combustion appliances may also pose carbon monoxide dangers, making routine maintenance a must on these systems.

Don’t play with fire. Catch dangerous heating and air issues before they result in damage and inventory loss. Make sure your system is installed correctly and maintained annually. Contact H & H Commercial Services to schedule preventative HVAC maintenance today.
