Maintaining HVAC systems in commercial buildings is complex work. It wouldn’t be a good idea to have just some random technician looking after a whole building’s system just so you can save a few bucks. Commercial HVAC system maintenance should be done by cooling and heating service in Las Vegas experts who’ve been in the business for more than a decade and have made it their life’s work. That’s us, Air Pro Master.


Residential HVAC systems, simply put, are much easier to maintain and look after. They’re much smaller, they don’t take up too much of a load, and their mechanics are much simpler to keep up. Commercial HVAC systems, on the other hand, are exponentially larger (depending on the size of the structure), take on much heavier loads to maintain a comfortable climate, and the system extends to every room and hallway within the structure. Effective and efficient maintenance would require a team of experts.

Cooling and Heating Service in Las Vegas: The Importance of Regular Maintenance

It is imperative to have commercial heating and cooling systems maintained and tuned up on a regular basis. Neglected systems tend to be prone to breaking down, to damages, and worse, could be an unwitting source of illnesses. Below is a list of signs that your HVAC is in dire need of a check up:

Higher energy bill

While it’s normal for energy bills to fluctuate every now and then, a consistent upward trend could be an indicator that your system isn’t running as smoothly as it ought to be. Extreme temperatures put a heavier load on the system which then results in higher energy consumption. So if it isn’t the height of summer or the dead of winter and yet your energy bill is through the roof, perhaps it’s time to have things checked.

Poor airflow or reduced indoor air quality

Indoor air quality is a critical component of a healthy environment. Once the air quality inside your space is compromised, you’ll start noticing that the people using that space will begin exhibiting signs like irritations of the eyes, nose, and throat, headaches, and much more.

Unusual smells

Weird smells are most definitely a sign that you need to have your system checked. Below are specific odors you might want to watch out for:

  • Mold or musty smell – if you smell a moldy or musty smell, then that probably means there’s mold buildup somewhere. Because of the moisture to escape from the unit to the ducts, molds could grow and accumulate. Mold is toxic and causes serious illnesses and should therefore be immediately eliminated.
  • Rotten egg smell – if you smell rotten eggs in your space when no one has been eating any, then you probably have a natural gas leak. This is incredibly dangerous and should be checked out by a professional right away. This might require the space to be evacuated because of its potential danger.
  • Electrical or burning smell – if something smells like it’s overheating, then something probably is. Electrical problems can occur in the motor or other components which can then lead to electrical fires. This is exactly the kind of situation that you would want to avoid. If this happens, it’s best to cut off all electrical supply to the unit and call a professional technician to come and take a look.

Odd noises

If your unit is making unusual sounds, then that probably means that there’s something wrong. Strange noises like squeaking, grinding, and grating shouldn’t be ignored. This usually means that something in the unit needs to be repaired or replaced.


There shouldn’t be an accumulation of water around your HVAC system. Whether it’s just a small leak or an actual puddle, this means that your unit is having some issues and needs some TLC from a professional.

Unevenly heated or cooled rooms

When each room in your space has a different temperature, this is usually a sign that your system isn’t working efficiently. While this is more common in older systems, a poorly installed or poorly designed air distribution system could also be to blame.

Age of the HVAC system

If you have an older system, then that in itself is reason enough to have it routinely checked. If it’s 10 years old and older, the chances of something going wrong are significantly higher than if it were brand new. This is usually the time when you might want to consider getting a new system installed instead as this might actually be more cost-efficient. Industry studies have shown that HVAC systems today are as much as 60% more efficient than ones that are over 10 years old.
