A commercial ac service and maintenance contract is an agreement or contract made between you and an Heating, Ventilation and Air conditioning (HVAC) & Refrigeration contractor for scheduled inspections and maintenance of your heating, ventilation and AC air conditioning unit.  PSG offers AC air conditioning service and maintenance contracts throughout all suburbs of Melbourne and Perth.
Your HVAC and Refrigeration tune-up is generally scheduled in the spring or autumn to maximize the efficiency of your system during its peak hours of operation. Beyond helping to lower your utility bills, these tune-ups also safeguard against potential system failures and extend the life of your HVAC system. 
Preventative maintenance and timely Heating, Ventilation, Commercial Air conditioning & Refrigeration tune-ups are a precautionary measure to prevent breakdowns and the need for costly repairs.  It also helps you save on energy efficiency.
• Improved indoor air quality
• Increased indoor comfort
• Lower heating and cooling energy bills
• Increased protection of the property and its furnishings
• Improved occupant safety
• Longer hvac equipment life

Improved hvac equipment reliability.  

The Benefits Of HVAC Service Plans 

Cleaning the coils—Chiller performance is related directly to heat transfer efficiency. Dirty evaporator and condenser tubes decrease a chiller’s ability to transfer heat, thereby increasing a compressor’s energy consumption by as much as 30 percent or more.

When condensing temperatures rise from 35°C to 40°C, cooling capacity is cut by 7 percent. For a 10-ton unit, this wastes about $550 per year. Cleaning the coils typically costs about $95, so it would pay for itself in just over two months

While the financial benefits of regular commercial air conditioning unit & refrigeration maintenance are numerous and might outweigh the cost of a contract, there are other considerations to be aware of:

  • Ensuring Your Safety – Testing of all safety mechanisms and parts verifies that your HVAC system is safe and functioning properly.
  • Increasing Efficiency – Making the appropriate adjustments to your equipment ensures that it’s running at optimal efficiency. Clean air filters generate maximum airflow, while debris-free indoor and outdoor coils create more efficient heat transfer.

WARNING: Inefficient HVAC equipment may be accounting for up to 70 percent of your energy bill!

  • Improving Durability - HVAC service plans extend the life of your ac air conditioning units by as much as 50 percent.  Avoid expensive air conditioning breakdown and repair call outs, make sure you regularly maintain your valuable air conditioning equipment
  • Increasing Your Property Value - Keep records of your service plan, tune-ups and other paperwork to increase the value of your property. If you plan to sell your home or commercial premises, these records make the negotiating process less daunting.  
  • Getting Speedier Service – PSG provides priority service to customers on a service plan. If your Air conditioning (AC) unit breaks down in the middle of a summer, the expedience of support that comes with a service plan is a real sweat saver.

PSG are experts in building services maintenance and facilities management

PSG can help building owners and managers optimise existing commercial air conditioning & other HVAC systems in order to reduce energy costs.  Optimisation includes:

  • The use of control systems to ensure that the right amount of air conditioning is provided when and where it is required

  • Temperature controller thermostats to reduce demand and save energy

  • Streamlined air distribution systems reduce the demand for fan power and HVAC unit capacity.  This reduces running costs and improves indoor comfort.  For example, an increase in a ducts cross sectional area by 15% will reduce the friction rate by 50%, reduce pressure drop contribuited to by the ducts by 50%, reduce overall pressure drop by 40% and reduce fan energy consumption by around 15-20%

  • Insulate ducts to prevent undesireable heat transfer

Ventilation systems also benefit from optimisation by PSG:

  • High efficiency fans and motors with direct drives save significant amounts of energy

  • Variable speed drives enable fan speed to match the required air flow

  • Demand controlled ventilation adjusts outdoor air intake to maintain optimal indoor air quality

  • Preventing over ventilation minimises undesireable heat transfer and humidity

  • Isolating fan motors prevents unwanted heat transfer

Proper maintenance means your HVAC system will continue operating at its optimal energy efficiency; maintain occupant comfort, maximise equipment life and minimise component failures.  Regular maintenance can conserve space conditioning energy use through measures such as:

  • Cleaning of distribution systems (fans, filters and ducts).

  • HVAC filters should be maintained or changed on a regular basis as recommended by the manufacturer, which can be as frequently as monthly during peak cooling or heating seasons. Proper filter maintenance will help avoid energy waste and overwork of equipment.

  • HVAC equipment needs to be maintained on a regular basis to ensure efficient operation, reliability and a longer life. Ensure the maintenance program includes the cleaning of condenser coils, evaporators and filters, and fix any duct leaks. Check refrigerant levels and airflows, and adjust each year as required. Old and inferior valves and steam traps can waste energy if not replaced.

Upgrades: Modern technology can reduce HVAC energy use by up to 50%.  As a result, buildings can use smaller HVAC systems which consume less energy and water.

When replacing HVAC systems, consider high-efficiency units. Replacing air conditioners that are more than 10 years old can save 20-40 per cent of your climate related energy costs annually, and reduce your carbon emissions.  New inverter technology can save up to 30 per cent of energy consumption, compared to conventional air conditioners. Fixed speed compressors will run at full capacity and will stop and start automatically to maintain the desired temperature, whereas an inverter unit will reach the desired temperature quicker and adjust its capacity to maintain a consistent temperature.

If you have premises to maintain, you will want to ensure that the building services, such the air conditioning, boiler and plumbing, are running reliably and efficiently. A breakdown in one of your systems can result in disruption, unplanned costs and discomfort for the building's users.  PSG Facility Ssrvices provides  Facilities Managers with information on key factors that influence the performance and efficiency of HVAC systems and important issues that must be addressed to get the best sustainability outcomes from existing and new maintenance contracts. Advice is given on environmental performance benchmarks and monitoring to target improvements and to verify the results.

PSG can add value to your business by identifying and implementing cost-effective measures that enhance building performance. We provide practical advice which assists building owners to proactively identify energy and water saving opportunities during routine maintenance and operational activities. 

Benefits of Best Practice Maintenance Practices

  • Attain sustainability goals
  • Improved occupant comfort
  • Retain asset value
  • Increase plant lifespan
  • Reduce energy consumption and expense

Benefits of programmed HVAC maintenance plans

  • HVAC preventive maintenance plans ensure your commercial air conditioning, heating, cooling and ventilation equipment remains in good repair. By inspecting their systems regularly, our technicians will catch minor problems before they grow into major ones.
  • Maintenance plans save you money by improving the energy efficiency of your equipment. You know that leaky old equipment wastes money. 
  • Eliminate surprises. A customer with a maintenance plan rarely gets hit with a sudden midwinter heating system replacement. If your equipment is failing, our technicians will be able to repair it during a tune-up — or at least warn you of what lies ahead and help you explore their options.
  • They are convenient. HVAC preventive maintenance agreements eliminate hassle for you. We will contact you when it’s time for a checkup.
