Commercial air conditioners need to run more and handle higher cooling loads than their residential cousins, so wear and tear related problems are much more common. For this reason, rather than simply failing to work at all, most commercial air conditioning systems first start having smaller problems as they age.
Armed with the ability to identify these smaller issues, you can have your building's air conditioning system professionally repaired before larger problems or catastrophic failures happen.
Listed below are four signs your commercial air conditioning system is malfunctioning and is in need of repair.
Sign #1: Your Power Bill Keeps Increasing
If your company's power bills keep increasing each month without any other reason, then you should suspect the air conditioning system isn't working correctly. As the system struggles to keep the building cool, it will draw more and more electrical power. This additional draw will slowly increase your bills each month.
Sign #2: Moisture Is Building Up Inside of Windows and Doors
One of the ways your commercial building's air conditioner cools is by removing humidity from the air. When moisture isn't being properly removed, then it will build up inside of the building. As this happens, you will see water condensation forming on the insides of windows and doors.
Sign #3: Indoor Air Quality Seems to Be Declining
Another common sign of a malfunctioning air conditioning system is the production of less than stellar indoor air quality. Often, when things stop working as well as they should, the building will start to have a musty odor or people will complain of slight burning smells.
Sign #4: The Air Conditioner Is Making Strange Noises
As the various parts of a commercial HVAC (heating, ventilation, and air conditioning) system start to age, it is common for them to start making strange noises. Sometimes worn bearings will make gravely or squealing noises as the blower motor runs. Other times, as the system is first starting up, you will hear thunking or clicking noises.
Additionally, a system with issues producing a steady stream of air will send more air to some ducts than others. This will lead to systemic noises in rooms being overloaded with air.
What to Do If You Notice Any of the Above Signs of Air Conditioner Malfunction
If you notice any of the above signs in your commercial building, then you must schedule an air conditioning repair appointment with a local HVAC service company, such as Day's Appliance Day's Appliance Repair Heatg & Air Condtng Co.
