NB Trades & Services supplies, installs, services and repairs air conditioning systems for homes, rental properties, businesses and commercial sites across Toowoomba and the Darling Downs.
Our team includes qualified air conditioning technicians, ARCtick certified technicians and licensed electricians, allowing us to coordinate both the air conditioning and electrical requirements through one local company. From a single split system in a bedroom to a ducted or zoned system for an entire property, we can help you choose, install and maintain the right system for your space.
Family owned and operating in Toowoomba since 1999, NB Trades & Services provides free fixed quotes, clear communication and quality workmanship backed by a 12-month labour warranty.
Choosing the right air conditioner is important for comfort, performance and running costs. Toowoomba homes and businesses need systems that can handle hot summer afternoons as well as cold winter mornings, so correct sizing and professional installation matter.
NB Trades & Services provides air conditioning installation for new systems, replacement systems, renovations, rental properties, commercial premises and whole-home comfort upgrades.
We install and advise on:
Our technicians can assess your property, recommend a suitable system and provide a fixed quote before work begins.
Split system air conditioning is a popular and cost-effective option for heating and cooling a single room, bedroom, office or open living area. It is often the simplest choice when you want reliable comfort in one part of the property without installing a full ducted system.
Daikin is our preferred and recommended brand, and as a Platinum Daikin dealer, we know the range well and can support customers with Australian parts and warranty backing. If you have another brand in mind, we can also quote and install other leading brands on request.
Because NB Trades & Services also provides licensed electrical services, the air conditioning and electrical requirements can be coordinated in-house through the same company.
Standard bedroom split system installation starts from around $2,500 fully installed, subject to system size, access, pipe run, electrical requirements and site inspection. Larger rooms, complex installations and higher-capacity systems will vary. We provide free fixed quotes so you know the full price before work starts.
Ducted reverse cycle air conditioning can heat and cool your whole home or business from one central system. With zoning, you can control selected areas and avoid running rooms you are not using.
NB Trades & Services designs ducted air conditioning systems around the property, taking into account room sizes, insulation, orientation, ceiling space, window placement and how the space is used.
Correct sizing is especially important in Toowoomba, where seasonal temperatures can vary significantly. An undersized system may struggle to keep up, while an oversized system can cost more to buy and run. Our team can assess your property and recommend a ducted air conditioning solution that suits your comfort needs and budget.
A multi split or multi head air conditioning system allows several indoor units to connect to one outdoor unit. This can be a practical option if you want to heat or cool multiple rooms without installing a full ducted system.
Zoned air conditioning is another useful option for homes and businesses where different areas are used at different times of the day. Zoning can help improve comfort and may reduce unnecessary energy use by heating or cooling only the areas being used.
NB Trades & Services can help you compare split system, multi split and ducted options so you can choose the most suitable system for your property.
Regular servicing helps keep your air conditioner working efficiently and can reduce the risk of breakdowns. Over time, filters, coils, drains, fans and electrical components can become dirty, blocked or worn, affecting airflow, performance and energy efficiency.
NB Trades & Services services all major types of air conditioning systems, including systems we did not install. We provide one-off servicing and scheduled maintenance for homes, rentals, offices, hospitality venues, retail spaces and commercial premises.
If your system has not been serviced recently, is not cooling or heating properly, or seems to be using more power than usual, our technicians can inspect it and recommend the right next step.

The ideal setting depends on balancing comfort and efficiency. For most people, a comfortable range in summer is 23–25°C, while in winter it’s 20–22°C. These settings help your air conditioner run efficiently without overworking. Keep in mind that comfort can vary depending on the room, the system type, and personal factors — young children, the elderly, or people with health conditions may prefer slightly different temperatures.
