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.
If your air conditioner is leaking, making unusual noises, showing error codes, blowing warm air or struggling to maintain temperature, NB Trades & Services can help.
We repair all major types of air conditioning systems, including split systems, ducted systems, multi split systems and commercial air conditioning units. Our technicians can diagnose the issue, explain the repair options and provide clear advice before proceeding.

Prompt, friendly and polite. Our air conditioner had stopped heating. A technician was out to check it and found it was no longer serviceable. A quote for a new one with installation was received within a few days and a new unit fitted within the week. The team arrived and worked quietly to install the new unit. Would strongly recommend.

We have used NB before and we used them again and have found them reliable and friendly with their service. Last time we had our 4 aircon units serviced and this time we had them install 3 aircon units also install 5 ceiling fans as well as replace 12 of our power points as they were not working safely and would recommend for anyone to use them they are also prompt with their time.

Just look at the other reviews, “5 Star” each time. Our experience was no exception when we had our new Daikin Air Conditioner installed by a most efficient team. From the moment we asked for a quote to the final installation, professional, courteous friendly service followed through. Liam, Steve and Nishal worked well as a team and they were very present to deal with. There was no mess to clean up after they had finished as it is part of the service. NB Trades and Service are our Electricians from now on as they cover all household requirements. I do not have any hesitation in recommending this company, they do have their act together, and we thank them for their service.
