Fan & Motor Cleaning

The fan and motor blades are prone to damage due to rust formation. In most cases, corrosion is an unavoidable phenomenon because excessive use and exposure to external elements like rain and snow eventually spoil the protective coating on the blades. Moreover, the accumulation of dust, dirt, and debris in the fan housing can also hinder the operation of the system over time. It leads to noise generation and vibration which can, in turn, lead to grinding, chipping, and crack formation. Our HVAC maintenance specialists can clean the dirt buildup to ensure smooth operation. Additionally, we can perform vibration analysis and alignment tests to make sure that the system continues to runs reliably.

Heat Exchanger Inspection

The heat exchanger is the main component responsible for heating the air as it passes through the HVAC system. It is a complex unit that comprises several metal tubes, wires, and coils to properly warm the air before it’s circulated indoor. Minor damages like rust or cracks in the heat exchanger can not only affect the air temperature and quality but also pose a risk of fire due to the heated elements. During your unitary HVAC service, we will thoroughly inspect the heat exchanger for any hidden damages or warning signs such as abnormal vibration, temperature fluctuations, smoke release, etc to reduce the risk of untoward accidents and unexpected heating system failure.

Voltage Testing

A voltage imbalance can give rise to serious safety issues and must not be taken lightly. Whether you have noticed voltage variations in your HVAC system or not, it is recommended to perform routine voltage checks to ensure that the heating and air conditioning units are drawing no less and no more than the power needed for smooth operation. High voltages can cause the motors to become overheated, while low voltages lead to amperage increase, which can cause a unit meltdown or even fire in the branch wiring.

Electrical Connections Inspection

Loose or deteriorated electrical connections can create excessive heat, reduce system performance, and increase the risk of equipment failure. Our technicians inspect wiring, terminals, and electrical components for signs of wear, corrosion, or overheating and tighten connections where appropriate.

Thermostat Inspection & Calibration

A properly functioning thermostat helps maintain consistent comfort while minimizing unnecessary energy use. We verify thermostat operation, check calibration, and confirm that the system responds correctly to heating and cooling demands.

Evaporator Coil Inspection

The evaporator coil plays a key role in cooling and humidity control. Dirt buildup or restricted airflow can reduce efficiency and place additional stress on the compressor. We inspect the coil for cleanliness, damage, and proper operation, recommending cleaning if needed to restore optimal performance.

Condenser Coil Inspection

Outdoor condenser coils are exposed to dirt, leaves, and other debris that can reduce heat transfer and system efficiency. We inspect the coil condition and recommend cleaning when necessary to help improve cooling performance and reduce energy consumption.

Refrigerant Inspection

The correct refrigerant charge is critical for efficient cooling performance. Low refrigerant levels may indicate a leak and can reduce cooling capacity while increasing operating costs. We inspect refrigerant pressures and system performance to identify any potential issues that require further attention.

Condensate Drain Inspection

Blocked condensate drains can lead to water damage, mold growth, and system shutdowns. We inspect the drain line, drain pan, and condensate removal system to ensure proper drainage and help prevent moisture-related problems.

Blower Assembly Inspection

The blower assembly is responsible for distributing conditioned air throughout the building. Dust accumulation or worn components can reduce airflow and increase energy use. We inspect the blower wheel, housing, and related components to help maintain consistent airflow and reliable operation.

Belt Inspection & Adjustment

On belt-driven systems, worn or improperly tensioned belts can reduce airflow and increase wear on motors and bearings. We inspect belt condition, alignment, and tension, making adjustments or replacement recommendations when necessary.

Safety Control Inspection

Safety controls protect your HVAC equipment from operating under unsafe conditions. We verify the proper operation of key safety devices, including pressure switches, limit controls, and overflow protection, to help ensure reliable and safe system operation.

Airflow Inspection

Balanced airflow is essential for maintaining comfort and equipment efficiency. We inspect supply and return airflow, identify potential restrictions, and evaluate overall air distribution to help ensure the system is operating effectively.

Overall System Performance Check

As part of every preventive maintenance visit, we perform a comprehensive operational check of the HVAC system. This includes evaluating equipment performance, listening for unusual noises, checking operating temperatures, and identifying any developing issues that could impact reliability or efficiency.
