If problems develop with the delivery of heated or cooled air at a business site, work could significantly suffer. Fortunately, many commercial HVAC issues involve a simple fix. Here are some common problems in commercial HVAC systems in Oak Ridge, TN.

1. Not Heating or Cooling

If you notice that your air conditioning system is suddenly not cooling and is instead blowing lukewarm air from the vents, then there are several possible causes for this issue. Walk outside and see if your outside compressor is running when the inside blower is running. If not, first check the circuit breakers.

Another culprit can be a refrigerant leak, which will require the immediate attention of a professional technician. If there is a leak, the technicians at Cook’s Comfort Systems, Inc., can fix it and replace the refrigerant. If this is not the problem, then other causes can be a frozen condenser coil or a broken compressor.

2. Constant Running or Short Intervals Between Cycles

A loss of efficiency for your commercial HVAC system can be a problem. The increased run times can cause wear and tear and effectively age your system.

You will also notice higher energy bills. A probable cause of this decreased efficiency is usually dirt and dust that has collected on your air filters or on your coils.

Clogged air filters impede the flow of air into your system and cause your system to work harder to draw in the air. Dirt that has accumulated on your coils interferes with the heating or cooling transfer of energy. Other causes can be vents that are blocked or a problem with your ductwork.

3. Poor Indoor Air Quality

You want the indoor air quality in your building to be comfortable and healthy for the occupants. This is especially important for your employees and customers.

There are many ways you can improve the indoor air quality. Some examples include providing better ventilation, adding air purifiers and cleaners and installing better grade air filters. Air filtration will remove small particulates like dust and pollen, and air purifiers and cleaners will remove gases, chemicals and volatile organic compounds or VOCs.

These systems can be added to your HVAC system and thus benefit larger areas than if added as portable solutions. You can also add humidifiers and dehumidifiers as well. Our professional technicians at Cook’s Comfort Systems, Inc., are experienced with all indoor air products, and we can advise you on how to improve your indoor air quality.

4. Loud or Unusual Noises

If your HVAC system suddenly develops loud or unusual noises, then the cause can be any number of issues. If the noise is a screeching or squealing sound, this may indicate a need for lubricant or mean a fan belt may need replacing. Regardless, a serious issue may be at play and require professional services from our technicians with Cook’s Comfort Systems, Inc.

5. Not Powering on

When your system is totally unresponsive, it could be a problem with the thermostat. Thermostats are usually hard-wired, but many also have lithium batteries that are recharged by the wiring. In some cases, the battery can still fail and cause the thermostat to not work as expected.

To troubleshoot the issue, replace the battery. If the system can now power on, then that may indicate a need to replace the thermostat. The system may be failing to charge the battery correctly.

Commercial HVAC units are large and involved systems that require care and maintenance to stay in top condition and perform efficiently. However, even with careful maintenance and checks, your system can sometimes still experience problems.
