Matt and Lachy installed our 2 split systems this morning…. That did a fabulous job under very trying wet conditions….Their workmanship was outstanding, they were very professional, and left everything clean and tidy. Thankyou so much….. We would certainly recommend Koolair to anyone requiring a fabulous heating or cooling system done properly and at a great price.

The quote was keen and Daryl got back to us the next day. We rang to accept and Daryl asked when did we want it, we said soon and he said how about tomorrow. They arrived on time and in a couple of hours it was in and running. Unbelievably slick operation with top quality results. Top marks to Hayden and Tyler for the install, Daryl for the quote and handling the rebate for removal of the old gas appliance and Ebony for follow up. We found this business from a friends recommendation and I will similarly recommend to anyone.

From quote by Daryl to installation by Matt and Stirling, could not fault commitment to perfection for a job well done. Matt and Stirling were brilliant in transferring the old system to the bedroom and installing the more powerful Daikin split system in the kitchen/family room. Thank you so much for your expertise. Lovely team all round.

Heating and cooling for Traralgon homes

Traralgon winters bring frosty mornings, and summer brings its share of hot afternoons. A reverse cycle air conditioner covers both, so one system can replace the separate heater you run all winter.

For one room or an open living area, a split system is the usual starting point. If you want every room heated and cooled from one controller, ducted air conditioning runs through the ceiling to vents in each room. Zoning lets you heat the bedrooms at night and the living areas by day.

We install wall splits, floor consoles, ceiling cassettes, multi splits and ducted systems, so we can match the unit to the room. Moving into a house with an existing system? Book a service before the first winter, and we’ll tell you what condition it’s in.

Optionally link “split system” and “ducted air conditioning” in the second paragraph to the service URLs above. Do not add a CTA Mark did not write.

Since 1998: Daryl’s story

Daryl Koolen started his apprenticeship as a refrigeration mechanic when he was 15. He’s now spent more than four decades in refrigeration and air conditioning, and he still runs Kool Air as a small family business in Traralgon.

That background shows in how the work gets done. Your system is sized on site, and the team cleans up before leaving. We service and repair what we install, so one local team looks after your system for its whole life.

Daikin systems you can see running in our showroom

Free consultations and a Daikin showroom

You don’t need to know which system you want before you call. We come to you and talk through how you use the house, room by room.

If daytime doesn’t suit you, the visit can be after hours or on a weekend. Afterwards we send a written quote. Ask us about rebates when we visit, and we’ll guide you through what’s available.

Most of the systems we install are Daikin. If you’d like to compare models first, you can see working ones at our showroom at 4/12-13 Nefertiti Court before you choose.

Servicing and repairs when you need them

A yearly service keeps your system clean and efficient, and it’s the easiest way to catch a fault early. We service most brands, including systems someone else installed. If you’ve noticed your system getting noisier, or your power bill creeping up, mention it when you book so we can check it.

If your air conditioner stops working, call the office on (03) 5174 8227. For after-hours calls, the number is on our repairs page.

Air conditioning for Gippsland businesses

We also fit and maintain systems for shops and offices.

If your business needs regular servicing, our commercial maintenance plans keep it on a schedule.

Recent work includes a 14kW Daikin cassette replacement at Subway Traralgon and a commercial ducted install in town. Read the case studies or see commercial air conditioning.
