HVAC (heating, ventilation, and air conditioning) systems are most likely responsible for monitoring and adjusting the indoor temperatures of your home and work spaces. Whether you are talking about heating and air conditioning in Toronto or Las Vegas, these systems affect your level of comfort indoors.
Those of you that own or manage large buildings with high occupancies will understand the importance of maintaining the functionality and efficiency of your HVAC system. Doing so requires you to enforce a routine maintenance schedule for every part of your HVAC system. Keep your business (and your HVAC system) running smoothly by following this simple checklist.
1. Use High Quality Filters and Replace Them Regularly
Filters come in all shapes and sizes, and with a wide range of filtering capabilities. The highest quality filters are able to remove the smallest particles from the air. Make sure the filters you use are capable of removing almost all toxic ingredients from the air.
Bbjenviro.com says that you should replace your filters every 1-6 months, depending on how fast they fill with particulates. Dirty filters do nothing to prevent mold from being dispersed through your building, and they put undue stress on your HVAC system.
2. Clean and Treat Your Evaporator and Condenser Coils
The copper condenser and evaporator coils can collect water and dirt in a couple of ways. Water, dirt (for nutrients), and mold spores are all that are needed for mold to thrive in these systems. By cleaning them inside and out at least once a year, you can keep this growth at bay. Once cleaned, you should apply an antimicrobial treatment that will prevent spores from taking hold in or around the coils.
3. Inspect and Clean Areas around Air Intakes
Water tends to accumulate near air intakes. Twice a year, you should look at all of your intakes and clean any water, dirt, or mold around them. Again, the application of HVAC-specialized antimicrobial treatments will keep the mold away from these areas.
4. Locate and Repair Air Leaks
Few things suck the efficiency out of an HVAC system faster than air leaks. Air leaks can happen anywhere, but they usually occur at junctions. You should visually inspect all of the air ducts in your system at least once each year.
5. Clean the Air Ducts
Dirt, moisture, and other debris can build up in air ducts over time. In extreme cases, air ducts can become completely clogged, which can be detrimental to the system in many ways. Luckily, it takes a while for that amount of dirt to build up. Cleaning your air ducts once every two years should be enough to keep them functioning properly.
6. Inspect, Clean, Treat, and Repair all Moving Parts
All HVAC systems come with a bunch of different moving parts. Dampers, fans, valves, and many other common components have pulleys, motors, sliding surfaces, and belts that all need to be regularly checked, cleaned, treated, repaired, and replaced. You should get your eyes on each of these parts every few months, and clean them at least twice a year.
7. Confer with an Expert
Honestly, there is a lot more that goes into properly maintaining large HVAC systems. While performing the above tasks regularly will do a lot to ensure the functionality of your system, consulting a certified HVAC technician will do even more. Good technicians can easily identify areas that need attention, and finely tune each part of the system. Make sure that you ask your technician to help you set up a more complete maintenance schedule.
Although HVAC systems in large buildings are complex, it can be easy to keep them running smoothly. By following a simple maintenance routine, logging the problems you come across, and consulting with a professional HVAC technician, you can ensure that your system stays in great condition.
