Improve indoor air quality and energy efficiency with a Mitsubishi Lossnay Heat Recovery Ventilation System, now available through Global Heating and Air Conditioning. As Canberra’s trusted experts in advanced climate control, we specialise in the supply and installation of energy-efficient ventilation systems that recover heat while delivering fresh, filtered air throughout your home or business.

Heat recovery ventilation (HRV) works by extracting stale indoor air and simultaneously drawing in fresh outdoor air, all while capturing and reusing up to 85% of the outgoing heat energy. This process not only reduces heating and cooling costs but also helps maintain optimal humidity levels, reduce condensation, and eliminate airborne pollutants.

The Mitsubishi Lossnay system is one of the most innovative solutions on the market, offering whisper-quiet performance, advanced filtration, and seamless integration into existing HVAC setups.

Ideal for airtight modern homes and commercial spaces, it’s the perfect solution for maintaining a healthier, more comfortable indoor environment all year round. Whether you're upgrading your ventilation system or building a new energy efficient space, trust our team for expert Lossnay installation in Canberra and surrounding regions.

At Global Heating and Air Conditioning, we specialise in custom climate control systems for wine cellars, designed to protect valuable wine collections in both residential and commercial settings. Preserving the integrity of fine wine requires more than a basic cooling system, it demands a precision-engineered wine cellar HVAC solution that maintains consistent temperature and humidity levels all year round.

We install advanced wine cellar cooling systems that are tailored to each unique space, offering quiet operation, discreet design, and seamless integration into even the most luxurious cellars. Whether you’re a private wine collector or managing a professional wine room, our Canberra-based team delivers expert installation using only premium-grade equipment. Our solutions ensure ideal aging conditions and long-term wine preservation, combining performance, elegance, and reliability.

If you’ve noticed your outdoor unit pausing or emitting steam during freezing conditions, don’t worry,  it’s likely in defrost mode, a normal and essential part of how your heat pump or reverse cycle air conditioner operates in winter. When outdoor temperatures drop below zero, moisture in the air can freeze on the outdoor coil, restricting airflow and reducing efficiency. To maintain performance and prevent damage, the system automatically activates a defrost cycle.

During this process, your unit temporarily reverses operation to warm the outdoor coil and melt away any ice buildup. While in defrost mode, you may hear a slight change in sound, notice a temporary stop in warm air, or see steam rising from the unit,  all of which are completely normal.

Once the cycle completes (usually within 5-10 minutes), the system returns to heating mode. This feature ensures your air conditioning system remains efficient and reliable, even in Canberra’s coldest months. If you're experiencing extended or frequent defrost cycles, it may be a sign your unit needs servicing, and our expert team is here to help.

Regular return air filter cleaning is one of the simplest and most effective ways to maintain the performance of your heating and cooling system. Over time, dust, pet hair, and airborne particles build up in your filter, restricting airflow, reducing energy efficiency, and affecting indoor air quality.

A clogged filter forces your system to work harder, which can lead to higher energy bills, reduced comfort, and unnecessary wear on components. In homes and businesses across Canberra, we recommend cleaning your return air filter every 1-2 months, especially during peak usage periods or if you have pets, allergies, or live in a dust-prone area.

How to Clean Your Return Air Filter:

1. Turn off your air conditioning or heating system.
2. Open the return air grille and carefully remove the filter.
3. For reusable filters: vacuum gently or rinse with warm water and let it dry completely before reinstalling.
4. For disposable filters: replace with the same size and rating as recommended by your system manufacturer.

Regular maintenance not only helps your system run more efficiently but also improves indoor air health for you and your family. For professional advice or air filter maintenance in Canberra, contact our team at Global Heating and Air Conditioning.
