Commercial buildings are often big, busy, and full of people. That means that HVAC (heating, ventilation, and air conditioning) systems have to work harder than ever to keep everyone comfortable. But that doesn’t mean that the systems are immune to wear and tear. In this article, we’ll explore some basic tips for keeping your HVAC system in good working order.

An overview of HVAC systems


Commercial buildings rely on air conditioning and heating to keep employees comfortable during the summer months and to maintain a consistent temperature in the winter. Cleaning and maintaining your HVAC system is key to ensuring that your building stays operational. Here are some tips for cleaning and maintaining your commercial HVAC system:

  1. Check the filters on a regular basis. Filters catch debris and dust, which can block airflow and damage equipment. If the filters are dirty, replace them as needed.
  2. Check the HVAC units for proper alignment and operation. Units should be placed at an adequate distance from walls and other objects and should be level to minimize drafts. Alignment can be checked by using a spirit level or a laser pointer.
  3. Inspect ductwork for cracks, leaks, or other damage. Ductwork should be cleaned if it becomes dirty or damaged, in order to avoid serious problems down the line.
  4. Clean the exterior of the cooling towers regularly. Cleaning can prevent bacteria buildup that could lead to corrosion, which could then cause serious problems with the cooling system.

If your HVAC system is not operating properly, it’s important to get it serviced as soon as possible. A qualified professional, such as HVAC service phoenix AZ, can diagnose the issue and recommend a course of action to fix it.

The five most common types of problems with commercial HVAC systems

  1. Dirty filters – HVAC systems work best when the filters are clean. If the filters are dirty, the air inside the system will be dirty too. This can lead to problems with your heating and cooling, as well as allergic reactions in people who are around the system. Regularly check your filters to make sure they’re clean.
  2. Obstructed vents – Vents that are blocked can cause your HVAC system to work harder than necessary to cool or heat the building. This can create excessive noise and fumes, and it can also lead to a higher energy bill. Clear any obstructions from your vents and keep them free of dust and debris to prevent these problems from happening. If you have a prepaid electricity plan and constantly use the air conditioner, your monthly cost will be more than average, so it’s a good idea to look at Just Energy rates as well.
  3. Damaged or old equipment – Old or damaged HVAC equipment can lead to a number of problems, including decreased efficiency and increased wear on your system. If you notice any signs of damage or wear on your equipment, contact a professional for help.
  4. Incorrect settings – If you’re not using your HVAC system the way it was designed to be used, it may not work as well as it could. Make sure you adjust your settings regularly to ensure maximum efficiency.
  5. Unseasonable weather – Weather can affect the performance of your HVAC system in a number of ways. If you notice your system isn’t working as well as usual in cold or hot weather, it may be time to adjust your settings.

How to clean and maintain a commercial HVAC system


When it comes to keeping your commercial building’s heating, ventilation and air conditioning (HVAC) system in top condition, there are a few tips you can follow. Here are some of the most important:

  1. Regularly check the filters – A dirty HVAC filter can lead to increased energy costs and shortened system life. Check the filters monthly and replace them as needed.
  2. Keep the ductwork clean – Clean ductwork helps ensure efficient airflow and proper insulation. Use a duct cleaning service or a shop vacuum to clean ducts on a regular basis.
  3. Maintain the HVAC unit – Check for loose connections, cracks in the unit’s casing, and other signs of wear and tear. If necessary, make repairs or replace parts as needed.
  4. Tune up the HVAC system – Periodic tune-ups help ensure that your HVAC unit is running at its best and uses less energy. Schedule an appointment with your HVAC specialist to have everything checked out.


Commercial buildings can be particularly challenging when it comes to HVAC cleaning and maintenance. Here are a few tips to help make the process easier:

  1. Plan ahead – know what needs to be cleaned and when, so you can schedule your employees accordingly.
  2. Use the right tools – from vacuum cleaners to air purifiers, use the right equipment for the task at hand.
  3. Keep an eye on the temperature – if the temperature inside is too high or too low, it will affect how well your system works.
  4. Be proactive – clean as you go, rather than waiting until something becomes visibly dirty before taking action. This will save time and energy in the long run!
