HVAC Problems & their Reasons
Systems for commercial heating and cooling are built to deliver dependable performance for a long time. Eventually, the system’s performance will decline as the hardware ages. Here is a brief explanation of five of the most Common HVAC Problems.
The main goals of an HVAC system are to offer thermal comfort and support the maintenance of acceptable indoor air quality through adequate ventilation and filtration. One of the biggest energy consumers in schools is the HVAC system. Numerous other high performance objectives, such as water usage (water cooled air conditioning equipment) and acoustics, can also be impacted by the HVAC system’s design and selection.
1. Insufficient Heating or Cooling
Refrigerant, a liquid substance required for the removal of heat and creation of cool air, is a component in cooling systems. The equipment won’t cool efficiently if the system loses refrigerant due to leaks or theft. Restoring the system’s cooling capacity normally only requires a refrigerant recharge. One of the most frequent issues with HVAC systems is a lack of refrigerant.
An air conditioner’s evaporator coils may freeze over, forming a thick layer of frost that hinders the system’s capacity to cool. Usually, all that is required to get the system to start cooling again is to defrost the coils and remove the accumulated ice.
2. Efficiency Loss
Your monthly heating or cooling costs may significantly increase as a result of HVAC systems losing efficiency. This occurs as a result of the system working harder to run more frequently in order to make up for the loss. Have your HVAC system inspected by a specialist if you’ve seen a sudden increase in your energy expenses that can’t be attributed to increased use or weather-related problems.
3. Reduction in Indoor Air Quality
Your heating and cooling system’s air filters function to filter out dust, pollen, and other debris from the air that circulates through the systems. They do this to prevent such particles from entering the indoor air of your facility. If the quality of the air inside your home seems to be declining, check the air filters in the HVAC system and replace them if necessary.
Additionally, you can anticipate some degree of dehumidification from cooling systems for your indoor space. Preventive maintenance on the equipment can be necessary if humidity levels are rising.
4. Strange or Enigmatic Noises
It could be a warning of major trouble if your HVAC system starts making unusual noises that you have never heard before or if the noises it typically makes get louder than usual. However, first check to see whether the noises aren’t the result of any loose parts, unsecured doors or access panels, or other items that rattle, bang, or clatter.
A fan or other moving item may need to be oiled if it is making screeching or squealing noises. They may also suggest that it’s time to replace the fan belt. If a gas furnace starts making internal popping or banging noises, this could indicate that gas is accumulating and is releasing it audibly.
5. Lack of Response
The thermostat is frequently at blame when your HVAC system completely fails to operate. Many contemporary programmable thermostats are battery-operated, so if the batteries die, the thermostat will turn off and the HVAC system won’t operate. If the thermostat’s screen is blank, check the batteries and replace them. One of the most frequent HVAC issues, the thermostat normally turns back on and the HVAC system resumes normal operation.
If changing the batteries doesn’t fix the issue, the thermostat may need to be changed. A malfunctioning HVAC system could also be brought on by a tripped circuit breaker. Because of power spikes in the electrical wires, breakers can trip. Breaker trips on occasion shouldn’t be reason for concern, but frequent trips could be a symptom of a serious condition. The system should function normally when you reset the breaker.
