Frequently Asked Questions: Expert Heating and Cooling Advice
At Grech Heating and Cooling, we are a locally owned and operated business here to help you choose the right system for your home or business. Below are the most common questions our Melbourne customers ask, answered with the honest and transparent advice you can rely on.
Our Services and Your Home
What is the best heating system for Melbourne’s winters?
We’re seeing more Melbourne families rely on split systems for reliable heating and cooling. These wall-mounted units are excellent for heating or cooling specific areas of your home efficiently. While ducted heating remains a trusted way to warm your entire space quickly through central vents, split systems offer incredible energy savings. We can assess your floor plan and recommend the best setup for your needs.
Is evaporative cooling or refrigerated air conditioning better for Melbourne?
Evaporative cooling uses natural air and water flow to keep you cool and is very affordable to run in dry heat. However, refrigerated air conditioning uses a compressor for stronger temperature control, which is much more effective on those humid Melbourne days. We supply and install both, helping you choose based on your budget and cooling needs.
Why is my gas heater blowing air, but it isn't feeling warm?
This usually means your system needs a professional repair. It could be a pilot light issue or a fault in the ignition if the air is moving but stays cold. As licensed specialists, we will assess the unit to find the problem. Don't risk a DIY fix with gas—call us for a safe, reliable repair to get your peace of mind back.
Can I add refrigerated cooling to my existing gas ducted heating?
Yes, this is known as a refrigerated A/C add-on. For this to work safely, your existing ducts must be properly insulated (rated R1.5 or higher). If your ducts are not the right fit, it can cause leaks or condensation damage. We will check your current setup and provide an honest recommendation on whether an add-on is right for your home.
Safety, Maintenance, and Reliability
How often should I get my gas heater serviced?
To keep your home safe and your system running well, you should book a service for carbon monoxide testing and gas heater servicing at least every two years. This is a safety check for gas emissions. Our qualified technicians perform a thorough inspection to protect your family. Regular maintenance also helps your system run at its best, saving you money on monthly energy bills.
Why does my air conditioning smell musty when I turn it on?
A musty smell usually means the system is overdue for a clean. Dust or moisture can build up on the internal parts over time, leading to odors. Our professional service includes a deep clean to remove these issues and ensure you are breathing fresh, clean air again.
Why is my split system dripping water inside?
A blocked drain pipe is often the culprit here. In Melbourne, dust or even small insects can block these lines over time. If water starts to drip, turn the unit off and book now for a repair. We will clear the blockage and ensure everything is flowing correctly to prevent damage to your walls or flooring.
How long does a typical heating and cooling system last?
Most reliable systems last between 10 and 15 years if they are well-maintained. We provide a workmanship warranty on our installs, and regular servicing is the best way to protect your investment and ensure your home stays comfortable for the long term.
Energy, Costs, and Savings
How can I reduce my heating bills this winter?
The best way to save is to set your thermostat between 18 and 20 degrees. Every degree higher can add 10 percent to your bill. You can also rely on us to assess your ductwork; if leaks are present, you are losing heat and money. A professional service ensures you are not paying for heat that never reaches your rooms.
Are there any Victorian government rebates for upgrading my system?
Yes! Through the Victorian Energy Upgrades (VEU) program, you may be eligible for a competitive price on upgrading old, inefficient heaters to energy-saving split systems. As an Australian family-owned company, we can help you navigate these rebates to make your upgrade more affordable.
What is the ideal temperature setting for summer?
To keep cool without breaking the bank, set your refrigerated air conditioning to 23 or 24 degrees. Setting it to 18 will not cool the house any faster. It just makes the system work harder and increases your costs.
Is hydronic heating better than ducted heating?
Hydronic heating is heating that uses heated water, not blown air. It is a very comfortable, silent way to warm your space and is great for people with allergies. While the install cost is higher, it is an incredibly reliable and premium heating service. We can design a system that fits your home perfectly.
Local Expert Support
Does Melbourne’s high pollen count affect my system?
Yes, pollen can clog your filters, making your system work harder and reducing your indoor air quality. We recommend a regular service to clean or replace filters, especially before spring, to ensure your ventilation services are working properly for your health.
Can you help with dry air or humidity issues in my home?
We supply and install humidifiers to help balance the moisture levels in your home. This is especially helpful during winter if heating dries out the air. Proper humidity control improves your comfort and can even help protect your timber flooring and furniture.
What should I do if my heater or AC stops working suddenly?
We offer 24/7 emergency breakdown and repairs. If your system fails during a Melbourne heatwave or a freezing winter night, give us a call. We provide a responsive service to get your home back to a comfortable temperature as quickly as possible.
