A convenient, healthy and productive office or commercial space is very much dependent on an adequate commercial HVAC system. Be it an office building, a retail centre, a restaurant, or even an industrial facility, your heating, ventilation, and air conditioning system is the basis of the interior’s cosiness and air quality. The most carefully crafted commercial system, however, requires regular maintenance to work effectively.

Failure to maintain the equipment may result in increasing energy bills, unforeseen breakdowns, poor air quality and even the expensive breakdown of equipment. Conversely, a proactive maintenance schedule will increase the longevity of your system, enhance productivity, and retain your tenants, employees or customers.

With this detailed manual, you will learn exactly the maintenance that a commercial HVAC system requires, its importance, and how to create a schedule that protects your investment.

Why Commercial HVAC Maintenance Matters?

The Role of Commercial HVAC

A commercial HVAC system is responsible for:

• Controlling temperature and humidity.
• Air-filtration and air-circulation.
• Controlling energy consumption and expenditure.
• Securing equipment, inventory and building structure.
• Satisfaction of code and safety requirements.

The Cost of Neglect

Failure to maintain or being late in maintenance may lead to:

• Increased energy charges through poor operation.
• Increased breakdowns and more costly.
• Reduced equipment life span.
• Uncomfort and IAQ deficiencies.
• Refunded warranties and code violations.
• Unexpected downtimes and revenue loss.

The Benefits of Preventive Maintenance

• Lower operating costs
• Fewer emergency repairs
• Longer system life
• Cosy comfort and air quality.
• Meeting of regulations and warranties.
• The tranquility of the building owners and occupants.

Key Components of a Commercial HVAC Maintenance Plan 

A full maintenance program will encompass all the significant elements of your business system:

Air Conditioning (AC) Maintenance

• Check refrigerant levels, Coil inspection, Clean condensate drains and test controls of the AC system.
• Filter replacement: Replace air filters on a regular basis so as to keep the air flowing and the air clean.
• Cleaning of coils: Clean evaporator and condenser coils to enhance efficiency.
• Maintenance of fans and blowers: Inspections and lubrication of motors, inspection of belts and proper functioning.
• Calibration of thermostat: Good temperature regulation.

Heating System Maintenance

• Tune up the services of furnaces: Check burners, heat exchangers, and flues to detect safety and efficiency.
• Furnace service schedule: Annual or biannual tune-up should be followed according to the recommendations of the manufacturer.
• Installation of commercial furnaces: They should be well installed, vented and controlled.
• Maintenance services: Observe the safety controls for the heating system, check to see if all the oil and gas connections are okay, and clean any components of the system.

Ventilation and Air Quality

• Duct cleaning and inspection: Ensure there are no leakages, blockages or insulations to remove.
• Ventilation fans maintenance: Ventilation fans service, check ventilation fans, including belts and lubrication of the ventilation fan.
• Air testing: Dust, allergens, and contaminants.

Controls and Automation

• Systems Test and calibrate building automation systems, sensors and thermostats.
• Zoning: Zone controls should operate correctly.

Equipment and Parts

• Equipment of HVAC: check wear, corrosion or damage. Replace as needed.
• Electrical parts: Wiring, connections and precautionary devices.

Essential Commercial HVAC Maintenance Tasks

Regular Inspections

Have professional regular checkups at least twice a year, once prior to the cooling and heating seasons. In the case of high-use or critical facilities, quarterly or even monthly checks are to be considered.

What’s included:

• Physical examination of every equipment.
• Leak inspection, corrosion inspection, and noise.
• Testing system functions in every mode.

Filter Changes

Clogged filters do not allow the air to pass through, lower efficiency, and damage the air quality. Change every 13 months or even every 3 months, in dusty locations.

Coil Cleaning

Coils with dust and debris minimize heat conduction and cause any system to labor. Wash evaporator and condenser coils at least once a year.

Drain Line Cleaning

Obstructed condensate outlets may result in water-related damage and mould. Wipe and empty drain lines on a regular basis with maintenance.

Fan and Blower Maintenance

Check and grease fan motors, fan bearings. Fasten belts and make sure they fall correctly.

Refrigerant Checks

Reducing refrigerants will decrease cooling power, which may result in damage to compressors. Add more refrigerant as needed.

Thermostat and Control Calibration

Temperatures Check and calibrate thermostats, sensors and controls to ensure proper temperature control.

Ductwork Inspection

Look to see whether there are any leaks, obstructions, or any problems with insulation. Stop leakages to enhance efficiency and comfort.

Safety Checks

Safety control measures of tests, gas/oil connections and electrical elements to avoid hazards.

Maintenance for Different Commercial HVAC Systems 

Rooftop Units (RTUs)

• Check and inside filters, fan and coils.
• Determine leakage and corrosion.
• Lubricate moving parts
• Control of tests and safety equipment.

Split Systems and Packaged Units

• Check both the indoor and outdoor units.
• Clean coils and filters
• Check the refrigerant and the connection to the electricity.

Ductless Systems

• Wash filters or change filters once after 1-3 months.
• Check both the indoor and outdoor units.
• Check refrigerant and electrical parts.

Boilers and Furnaces

• Check burners, heat exchanger and flues.
• Safety controls of tests and thermostats.
• Oil moving components.

Chillers and Cooling Towers

• Clean and examine tubes, fans and pumps.
• Check the level of water treatment and chemicals.
• Control of tests and safety equipment.

HVAC System Testing and Performance Checks

Why Testing Matters?

HVAC system testing is made to guarantee the safety, efficiency and prescribed operation of your equipment. Consistent testing will help to detect problems before they turn out to be expensive.

Key Tests

• Determination of the airflow: Proper distribution and comfort.
• Temperature difference: The heating and cooling system is tested.
• Refrigerant pressure: Leaks or undercharging.
• Combustion analysis: It ensures that the furnaces operate safely and efficiently.
• Electrical testing: Eliminates failures and fire.

Creating a Commercial HVAC Maintenance Schedule

How Often Should You Service a Commercial HVAC System?

• Biannual (once a year): Commercial building standard.
• Quarterly: When the systems are high-use, critical or old.
• Monthly: Change of dust or high traffic area filters.

Sample Maintenance Calendar

Spring (Pre-Cooling Season):

• Clean and inspect the cooling equipment.
• Replace filters
• Controlling tests and thermostats.
• Check refrigerant levels

Summer:

• Monitor system performance
• Address any issues promptly

Fall (Pre-Heating Season):

• Check and remove dirt in heating equipment.
• Replace filters
