Is your heating system ready for the coldest months of winter? With commercial HVAC systems it is necessary to do a bit of maintenance to ensure everything is working properly and efficiently.

Winter weather and freezing temperatures can wreak havoc on your system if you’re not prepared, and that can result in heating system failure at an inopportune time. Here are the most important steps to take in order to winterize your commercial HVAC system. 

 

Perform a Thorough Inspection

Start by inspecting the entire heating system, including every part that is indoors as well as outdoors. Go through the following list:

  • Check exposed pipes for proper insulation. Pipes that lack insulation can freeze and cause all sorts of problems. 
  • Look for signs of moisture or leaks. Moisture where it shouldn’t be usually indicates a leak that needs to be fixed. 
  • Check for cracks in any part of the heating system or ductwork. Cracks allow heat to escape outside rather than warming the inside as it should. 
  • Empty condensation traps. Condensation accumulates and will freeze in cold temperatures, potentially causing problems. 
  • Ensure there are no blockages in hoses or drainage tubes. Condensation needs to be able to drain out and the flow of air in both directions should be unencumbered. 
  • Listen for unusual sounds. If your system is making strange or louder than usual noises, there could be a part that is wearing out or some other mechanical issue. 

 

A thorough inspection can go a long way toward making sure there are no unexpected surprises. 

 

Basic Maintenance

Here are the most basic maintenance steps that should be done multiples times a year:

  • Replace the filters. Dirty, clogged filters are one of the most common problems with HVAC systems. Changing filters regularly keeps your system operating efficiently. 
  • Check carbon monoxide detectors. Many furnaces and heating systems produce carbon monoxide. If not properly ventilated, CO detectors are an important safety feature. 
  • Calibrate thermostats. Thermostats can sometimes deviate from their original temperature gauges, causing incorrect readings and operation of your heating system. 
  • Clean ducts and vents. Keeping ducts and vents clean will go a long way toward maintaining the efficiency and proper operation of your HVAC system. 

 

Professional Maintenance and Tune Up

Unless you are in the HVAC business, there are aspects of yearly maintenance that should only be handled by a professional. Depending on your level of comfort and expertise, you may even need an HVAC specialist to perform some of the items listed above. At the very least, it is necessary to have a yearly inspection and tune up for your heating system performed by a professional commercial HVAC technician.

When it comes to COVID-19 and HVAC systems, there are a lot of unknowns. Businesses hope to avoid the spread of the coronavirus among employees as much as possible. But how?

There are various ways that HVAC systems play a part in curbing the current global pandemic. Consider these COVID-19 HVAC questions and answers to help you make the right decisions for your business.

Can HVAC Systems Help Prevent the Spread of COVID-19?

Proper ventilation is pivotal in slowing the spread of viruses, including COVID-19. HVAC systems circulate air and reduce humidity, which prevents the virus from being able to live in the air. Heavy, moist air will hold more pathogens as the moisture gives them something to cling to. HVAC systems bring fresh outdoor air into the building and push stale indoor air out. Viruses can’t live in the open air long enough to be passed through the HVAC and infect anyone.

How Does UV Light Kill Viruses?

UV lights have the capability to destroy viruses. This is not new information, as scientists have been aware of this for decades. Wavelengths between 200 and 400 nanometers are the most effective. The way it works is that the ultraviolet light breaks apart the virus by destroying the bonds that hold it together (mostly hydrogen). The virus can’t survive and cannot infect anyone once it is dead.

While it can help to kill viruses, a UV light alone is not capable of completely eliminating COVID-19 from a building. The EPA (Environmental Protection Agency) recommends the use of UV light in conjunction with best practices recommended by the CDC (Center for Disease Control).

Is UV Light Safe for People?

UV light is radiation. This is why UV rays from the sun can cause skin cancer. Which begs the question, can UV light be harmful to people? And if so, should it be used in businesses around many people?

UV lights are installed deep in the HVAC system where the light itself, the radiation, will not come in contact with people. It is out of sight and only shines on the air as it passes through the HVAC ducts, meaning it cannot harm people. Professional HVAC technicians know how to carefully handle these UV lights to avoid exposure to radiation themselves.

How Can I Get a UV Light Installed in My Commercial HVAC System?

A commercial HVAC company can install UV lights at various points in your HVAC system to ensure the optimal amount of virus control. The size of your building and other factors will affect the placement and number of UV lights you’ll need to get the most virus protection possible.

With the introduction of COVID-19, employee safety in the workplace has become a bigger issue than ever. Keeping 6 foot spacing between workers and enforcing wearing masks and gloves in some industries has become the norm. But how does the building’s HVAC system play a part in keeping everyone healthy?

HVAC stands for heating, ventilation, and air conditioning. The keyword here is ventilation. It’s important to keep air moving and your commercial HVAC system is an integral part of that. But when it comes to HVAC systems and COVID-19, you may have some questions. Here are some frequently asked questions and answers that can help you stay informed.

Is it Safe to Use Your Commercial HVAC System During COVID-19?

According to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), there is no danger of spreading COVID-19 through your HVAC system. In fact, allowing your HVAC system to operate as usual is helpful to prevent the spread of the disease. Your HVAC system continually cycles air.  As the air cycles, it moves through a filter that eliminates many of the particles from the air. Regular use of commercial HVAC filters are not proven to trap pathogens such as viruses, but they may help.

Are Commercial HVAC Services Available Right Now?

As a result of all the business closings due to COVID-19, it can be hard to know what’s open and what’s not. But HVAC companies are considered essential businesses, so you can still schedule service for your commercial HVAC system.  Maintenance is important for proper operation of your system. A well-tuned up HVAC system will do a better job of keeping your indoor air clean and healthy. So there’s no reason to put off your regularly scheduled maintenance or to avoid calling for repair if it is needed.

Can an Air Purifier Kill Coronavirus?

There is no official evidence that proves that an air purification system is capable of killing the coronavirus that is causing the current outbreak known as COVID-19. Air purifiers do eliminate finer, even microscopic particles from the air and in significantly greater quantities than the average HVAC filter. Another benefit of an air purification system is that it can create new air molecules that are clean and uncontaminated. Ultimately, it is important to note that the success of an air purifier in eliminating COVID-19 is unknown, but it may help.

HVAC Maintenance Tips for Business OwnersWhen it comes to running a business, your building is a large part of it. Of the many systems you may have operating in your building, your HVAC system is a crucial one. The HVAC system, when working properly, provides a comfortable environment for employees, customers, and anyone else who enters the building. To keep your HVAC system operating properly, regular maintenance is necessary. Here are some helpful tips on HVAC maintenance for businesses.

Change your Filters Regularly

If there is one thing you can do between professional maintenance appointments that can make the most difference in your HVAC system’s performance, it’s changing your filters. The intake vents draw air into the system to condition it (heat or cool it) and then blow it back out into the building. The job of the filter is to block dust, dirt, and particles from being sucked into the ducts and inner machinery of your furnace and air conditioner. A dirty filter can let unwanted particles through, so regular replacement is necessary. Quarterly replacement is best, but twice a year is the absolute minimum. 

Why is this important?

  • Dust and other particles that get into the ducts can get into the working machinery of your heating and cooling systems. When your HVAC system gets dirty, it doesn’t function as efficiently, if it functions at all. 
  • Any dust or particles that get past the intake filters can make their way through your system and back out through the vents, essentially blowing dust and other allergens around the building. 

Schedule Regular HVAC Maintenance

HVAC maintenance for businesses is just as important as it is for your home, if not more so. A business tends to be a larger building than a standard single-family home and is likely to contain more people on a daily basis. A business HVAC system will most likely be larger and involve a greater amount of ductwork and vents. Commercial HVAC companies recommend twice a year maintenance, once to focus your heating system and once to focus on your cooling system.

Why is this important?

  • Maintenance involves a thorough inspection of your system which will identify any potential problems, such as parts that are wearing out or loose. It can help you avoid unexpected breakdowns and emergency repairs. 
  • Keeping your HVAC system well maintained allows it to run at peak efficiency, which can save you money on your energy bill. 

Monitor and Control your HVAC System Via Integrated Systems

One of the best ways to keep on top of your HVAC system’s performance is through the use of integrated systems. Integrated systems, also known as automated building systems, is a method of networking all of your buildings’ systems (such as plumbing, security, HVAC, internet, phones, and more) and both controlling and monitoring them all at once using an intelligent software package that works with computers and handheld devices like smartphones and tablets.

Winterizing your HVAC systemAs the weather changes and we switch from air conditioning to heat there are important steps to take to prepare your HVAC system for the switch. This is something you should have done for your business to ensure optimal performance from your systems. When was the last time you needed commercial HVAC repair in Roanoke, VA? If it’s been a while since your last service, it’s probably long overdue. Follow these 5 tips for winterizing your company’s HVAC system. 

 

Schedule Preventive Maintenance

 Your HVAC system should have periodic maintenance performed by a professional heating and cooling service to ensure it is running properly and efficiently. HVAC experts recommend scheduling appointments twice a year; in the fall for your furnace and in the spring for your AC. Preventive maintenance consists of an inspection that identifies any potential problems such as parts that are wearing out and need to be replaced, a thorough cleaning of the system, and a general tune-up. This ensures your system is prepared to operate properly and efficiently for the season ahead. 

Replace Filters

All filters should be replaced at least every 6 months. This is often taken care of as part of preventive maintenance, but if not, it should be done around the same time. For absolute best performance, replace filters quarterly or even monthly. When filters get dirty the efficiency of your HVAC system declines. 

Check Thermostat Settings

When you switch your building over from air conditioning to heat it is important to check your thermostat settings and determine the optimal temperature for the building. If you have zone climate control you can adjust certain areas to heat to specific temperatures based on need. You’ll get optimal efficiency by using programmable thermostats that allow you to set different temperatures for different times of the day based on the typical occupancy of the building. 

Inspect Equipment

This should also be done as a part of your professional preventive maintenance, but it’s not a bad idea to do your own inspection as well. Make sure nothing looks off, that there are no obvious holes or cracks in the ductwork or other parts of the system. Mention anything you notice to your HVAC technician when they come to perform your inspection and tune-up. 

Assess Efficiency

Your HVAC technician can check your system for efficiency, but without regular data, it can be difficult to assess just how efficiently (or inefficiently) your system is operating. Consider integrated systems with automatic performance monitoring to constantly measure the efficiency of your HVAC system. If a decrease in efficiency is detected the system will alert you so that repairs or adjustments can be made. This can save you money over the winter.

Thermostat phootIt’s just about time for autumn leaves and temperatures to begin to fall, which means it is also time to think about furnace maintenance. Commercial HVAC (heating, ventilation, and air conditioning) systems are often more complicated than residential systems. They are typically larger in order to accommodate larger buildings and may include multiple units that need to be maintained. Every fall, the following steps should be taken to properly maintain your furnace. 

  • Replace filters.Most HVAC experts recommend replacing your filters monthly, but at the very least this should be done twice a year: in the fall and in the spring. Dirty, clogged filters are one of the main causes of heating system problems. As the old saying goes: an ounce of prevention is worth a pound of cure. You can potentially save yourself from a large, expensive repair bill by regularly changing your filters. 
  • Calibrate your thermostat. Check to see that the thermostat is properly sensing the temperature and triggering the heat to come on when it should. This can be done by a furnace service in Roanoke such as Varney, Inc. 
  • Check your carbon monoxide detector. Make sure that your carbon monoxide detector has good batteries and is functioning properly. Furnaces produce CO, which can be harmful if not properly ventilated. Furnaces with a lot of soot buildup will produce higher than usual amounts of CO. An alarm will sound on your carbon monoxide detector if CO levels reach a dangerous point. 
  • Schedule a tune-up. The only way to be sure your furnace is in proper working order is to have a reliable, experienced HVAC service perform an inspection and tune-up. Any potential problems will be found and repaired before they can cause furnace failure. The system will be thoroughly cleaned and lubricated so that it’s ready for a cold winter.

back to schoolBack to school time is here. School buses are running, lesson plans are written, and young minds are open and ready to receive all the information they can handle. Getting children the best education possible is a lofty goal, but there are so many contributing factors. One such factor which may not get much consideration is the school’s HVAC system. In schools, having the furnaces and air conditioners serviced and maintained regularly will ensure the highest level of performance. High efficiency HVAC systems that receive expert services from a reputable heating and cooling company will help to keep students focused better with fewer health issues, because efficient air conditioners help to reduce allergens and humidity levels in the air, creating healthier air quality and a more comfortable environment.  

 High Performing Air Conditioning and Heating System Leads to Improved Learning Environments in Schools  

School children can be affected by the indoor environment of schools. If there are too many allergens in the air, and proper ventilation is not achieved, children may have trouble concentrating due to increased allergy symptoms or respiratory illnesses. When the school’s HVAC systems are functioning at full capacity, effectively filtering allergens and germs, students are healthier and more comfortable, able to think clearly and perform better. An evaluation by The United States Environmental Protection Agency on Indoor Air Quality & Student Performance among schools in the U.S. concluded that schools experienced lower absentee rates when efficient air conditioning was in place: 

Early studies in schools have found that air conditioning is associated with lower absentee rates or improved performance, and that schools with humidification systems are also associated with lower absentee rates.” 

Varney, Inc. provides services for commercial air conditioner and heating units in VA and the entire southeast, including annual maintenance and repairs.  

Keeping Your Commercial AC System Maintained Increases the Focus in the Classroom 

In schools, the students’ focus can be compromised if the air conditioning system does not receive regular maintenance. Students may have trouble focusing if they constantly complain about the temperature of the classroom. With a new commercial air conditioner, regular maintenance and expert repairs, a school can have an improved indoor air quality, resulting in better concentration and healthier, more focused students.  

Varney, Inc. Can Keep the Commercial Air Conditioner in Your VA School or Business Running Smoothly 

Whether you run a school or a business, providing clean, cool air will help your students, patrons, or employees think clearly and stay healthy.
