About us

For over 50 years, B W O'Brien and Co Ltd has kept homes and businesses comfortable across the Wairarapa region. Founded by Bernie O'Brien, we remain a true family business - now owned by Lyn and Colleen O'Brien, with Ash O'Brien as General Manager and Jon O'Brien as Lead Engineer.

As the region's only accredited Daikin Dealer, we're your local experts in refrigeration, heat pumps, and air conditioning for both homes and commercial spaces.

Managing Director Lyn O'Brien started his career as an apprentice right here in the Wairarapa before taking over in 1975, and he still personally oversees our work to ensure you get the best results.

Our experienced team doesn't just follow instructions - they take full ownership of every job, using their extensive knowledge to guide you through the best options for your situation.

We believe in putting our customers first, taking the time to understand your needs and ensuring you're completely satisfied with every aspect of our service.

We're registered members of the Climate Control Companies Association (CCCA) and IRHACE, so you can trust you're in good hands.

Get in touch with us for all your refrigeration, heat pump, and air conditioning needs - we're here to help.
