Common HVAC & Refrigeration Problems
Inefficient Operation
Dirty filters, clogged coils, and leaky ductwork reduce efficiency, leading to higher energy bills. Many times, the controls are improperly calibrated, contributing to inefficiency.
Inconsistent Temperatures
Uneven heating or cooling can result form aiflow imbalances, ductwork issues, or malfunctioning zoning systems. Hot and cold spots are a frequent problem.
Poor Indoor Air Quality
Inadequate ventilation, dirty filters, and mold growth can compromise IAQ, affecting occupant health. Industrial environments may have specific air filtration needs.
Refrigerant Leaks
Leaks reduce cooling capacity and can harm the environment. Commercial systems often use large refrigerant volumes, making leaks a significant concern.
Control System Operations
Faulty thermostats, sensors, or building automation systems can disrupt system operation. Complex control systems require specialized expertise.
Drainage Problems
Motors Compressors, and other components can fail due to wear and tear or lack of maintenance.
Drainage Problems
Clogged drain lines and pans can cause water damage and mold growth.
Economizer Issues
Malfunctioning economizers, which use outside air for cooling, can lead to energy waste.
Noises and Vibrations
Unusual noises and vibrations can indicate mechanical problems, such as worn bearings or loose components.
Exhaust System Issues
Inadequate exhaust ventilation can lead to buildup of pollutants, fumes, or odors.
Evaporating & Condenser Coil Fouling
Industrial environments often have airborne contaminants that can quickly foul coils, reduce heat transfer and efficiency.
Walk-in Cooler/Freezer Door and Seal Problems
Frequent use can damage doors and seals, leading to air leaks and increased energy consumption.
Glycol System Issues (Chillers)
Many industrial systems use glycol chillers. Problems include glycol leaks, pump failures, and inadequate concentration.
Complex Control Systems Malfunctions
Commercial and Industrial systems often use sophisticated control systems for temperature, humidity, and defrost cycles.
Defrost System Failures (Large Evaporators)
Large evaporators require robust defrost systems. Malfunctions can lead to excessive ice buildup, reducing air flow and cooling capacity. Defrost timers, heaters, and sensors are common failure points.
Refrigerant Recovery & Disposal
Due to the size of the systems, when repairs are made, large amounts of refrigerant need to be recovered, and disposed of properly.
