Frequently Asked Questions

Our technicians recommend servicing your heating and cooling system at least once every year. Regular maintenance ensures energy efficiency, optimal performance, and it also helps identify potential issues before they become major problems.

Some of the warning signs that indicate that your HVAC system requires repair or maintenance include insufficient heating and cooling, strange noises, unusual odors, the unit turning on and off automatically, inadequate airflow, a sudden increase in energy bills, or the unit not turning on at all. If you are experiencing either of these signs, it’s best to contact DGB Refrigeration Heating & Cooling to book an inspection for your unit.

In order to enhance the energy efficiency of your HVAC system, you have to ensure that your HVAC is properly maintained. This can be done by:
• Regular cleaning of the air filters
• Replacing old and worn-out air filters
• Sealing air leaks
• Ensuring proper insulation
• Using a programmable thermostat to regulate temperature settings
• Scheduling regular maintenance for your HVAC Unit

There are numerous heating & cooling systems available in the market including evaporative coolers, ductless split system air conditioners, ducted gas heating, ducted refrigerated air conditioning, heat pumps, multi head split systems, reverse cycle air conditioners, etc. However, deciding which unit is best suited for your property is something that requires professional help. Finalizing a system for your home depends on multiple factors that include:
• Size of your space
• Budget
• Energy efficiency requirements
• Personal preferences

The installation time can vary depending on the complexity of the system and the size of the project. On average, a complete HVAC system installation can take anywhere from one to two business days. However, it's best to consult with the DGB Refrigeration Heating & Cooling by dialing 03 7038 6918 to get a more accurate estimate based on your specific requirements.

There might be government rebates or incentives available for upgrading to energy-efficient heating and cooling systems. These incentives can vary over time and by location. The Victorian government keeps introducing various programs for upgrading your inefficient heating & cooling solutions to energy efficient systems. You can reach out to us at 03 7038 6918 and we can inform you of all the available programs.

If your heating or cooling system is not providing sufficient comfort, you can start by checking the air filters to ensure they are clean and not obstructing airflow. If the issue persists, it's best to contact a professional HVAC technician to diagnose and address the problem. There could be underlying issues with the system that require professional expertise to resolve.

To reduce the noise produced by your HVAC system, you can start by ensuring that the unit is properly installed on a stable surface. Additionally, regular maintenance, such as cleaning and lubricating moving parts, can help reduce noise. Upgrading to newer, quieter models or installing noise-dampening materials around the unit may also be effective solutions.

There are some maintenance tasks that you can perform on your own to help keep your heating and cooling system in good condition. These tasks include cleaning or replacing air filters, clearing debris and obstructions from the outdoor unit, keeping vents clear for proper airflow, and inspecting and cleaning the indoor and outdoor coils periodically. However, it's crucial to schedule professional maintenance at least once a year to tackle more complex issues and ensure optimal performance of your system.

There are several options for controlling and regulating temperature in different areas or rooms of your home. These include zoning systems that allow you to set different temperatures for different zones, ductless mini-split systems that provide individual control for each indoor unit, and smart thermostats that enable remote temperature adjustments through mobile devices. The best option depends on your specific needs and budget.

The average lifespan of a heating and cooling system can differ based on various factors, including the type of the system, maintenance record, and usage patterns. Typically, a well-maintained HVAC system can last between 15 to 20 years. However, if your system frequently breaks down, requires expensive repairs, or fails to provide efficient heating or cooling, it may be a sign that it's time for a replacement. It's advisable to consult with DGB Refrigeration Heating & Cooling to evaluate your system's condition and get recommendations based on its age and performance.

To ensure the safety of your heating and cooling system, it's important to follow a few key measures. Regularly check and replace batteries in smoke detectors and carbon monoxide detectors. Keep the area around the HVAC system clear of flammable materials. Schedule regular professional maintenance to identify and address any potential safety hazards. Finally, if you detect any unusual odors or suspect a gas leak, immediately evacuate your home and contact DGB Refrigeration Heating & Cooling for prompt assistance.

There are several ways to improve indoor air quality through your heating and cooling system. Regularly clean or replace air filters to remove dust and allergens. Consider installing air purifiers or air cleaners that can remove contaminants from the air. Ensure proper ventilation by opening windows when weather permits or using mechanical ventilation systems. Additionally, scheduling professional duct cleaning can help remove accumulated dust, debris, and pollutants from your ductwork.

Some common causes of HVAC system breakdowns or failures include:
• Lack of regular maintenance
• Dirty or clogged filters
• Refrigerant leaks
• Electrical component failures
• Thermostat issues
