Reliable HVAC systems are essential for businesses, yet common issues can interrupt operations. To prevent problems, every business should prioritize regular maintenance and repairs. Clogged filters or duct blockages often lead to poor airflow; fix this by routinely changing filters and inspecting ducts. Ensure thermostat accuracy and proper installation to tackle temperature control glitches. Refrigerant leaks compromise efficiency, so proactively check for and repair leaks. Scheduling expert visits for commercial HVAC repair Dallas helps minimize disruptions and optimize performance in commercial settings. Here are a few common HVAC problems that you may encounter- 

1.    Short Cycling

Short cycling is a common issue in commercial HVAC systems where the system turns on and off frequently. It can happen if the system is too big for the space or needs to be properly maintained. It leads to problems like higher energy bills and system damage. Causes include an oversized system, dirty filters, blocked ducts, faulty thermostats, or refrigerant leaks.

To fix it, ensure the HVAC system fits the space, maintain it regularly by changing filters and cleaning ducts, and get professional help if you need commercial HVAC repair Dallas TX. Addressing short cycling promptly is essential to prevent increased wear, frequent maintenance, and higher costs.

2.    Leaking Refrigerant

Leaking refrigerant in commercial HVAC systems can lead to various issues, often caused by poor maintenance or aging systems. Regular inspections and maintenance are essential to identify and address potential problems early and ensure efficient operation. If signs of a refrigerant leak appear, prompt, professional assistance is necessary to prevent further damage or the release of harmful gases. Schedule a visit with HVAC experts near you.

3.    Dirty Filters

Dirty filters in commercial HVAC systems pose several issues, including reduced efficiency and higher energy bills. They affect proper airflow, overworking system components and leading to potential breakdowns. It is when you may need commercial HVAC repair in Dallas TX. The dirty filters cause the system to operate at increased temperatures, increasing energy consumption.

To prevent these problems, regular inspection and replacement of commercial HVAC filters are advised at least every three months. The checks for accumulated dirt or debris are also essential, prompting immediate replacement if any issues are identified. Regular inspections and servicing of the entire HVAC system further ensure optimal functionality.

4.    Dirty Condenser Coils

• Dirty coils make the unit work harder, consuming more energy.
• Restricted heat exchange leads to slower and less effective cooling.
• Additional strain on the system increases the breakdowns.
• Dirty coils compromise the efficient transfer of heat.
• Reduced capacity results in a longer time to reach the desired temperature.
• Inefficient cooling can lead to discomfort and health issues for users.

To prevent these issues, the HVAC units should be serviced; the condenser coils should be inspected and cleaned when needed. It will ensure that the unit runs as efficiently as possible and that the cooling capacity is not affected by dirty coils. Regular maintenance also reduces the risk of breakdowns, which can be costly and time-consuming.

5. Clogged drain

Maintaining your commercial building’s HVAC system from a clogged drain is essential. It is caused by dirt and debris buildup. Neglecting it may seem like a minor problem, but it can result in water overflows, damaging the HVAC system. You can book a professional HVAC repair in Dallas, TX, to deal with it. Regularly inspect and clean the drain line to prevent clogs and remove accumulated debris.

Additionally, check and replace HVAC filters to avoid drain line blockages. If a clog occurs, seek professional help promptly. Expert HVAC technicians can assess the situation, clear the clog, or replace the drain line as needed, ensuring the system’s optimal functionality.

6.    Malfunctioning Economizer

• Malfunctioning economizers lead to unpredictable indoor temperatures.
• Efficiency issues make HVAC systems work harder, raising energy bills.
• Malfunction can result in overly humid, dry, or dusty air, impacting health and comfort.
• Occupants experience discomfort due to temperature fluctuations and air quality problems.
• Systems may be strained, leading to increased wear and potential breakdowns.
• Malfunction compromises overall HVAC system efficiency.
• Non-compliance with regulations may arise due to a faulty economizer.

7.    Loose Evaporator Belt

A common issue in commercial HVAC systems is a loose evaporator belt, which transfers power to the fan to cool the coils. If left unattended, it can lead to system shutdowns, resulting in heating and cooling loss. Additionally, it may cause the fan motor to overheat prematurely. Detecting this problem involves checking the belt for wear, cracks, or fraying and adjusting the tension appropriately. Regular inspections and prompt replacement of a worn or damaged belt are crucial for preventing disruptions in HVAC functionality.

The Bottom Line

Knowing the common problems with commercial HVAC systems can reduce the time it takes to diagnose and repair them. With effective maintenance, these issues can improve and become more costly.
