Commercial heating, ventilation, and air conditioning systems are a key focus for Davies Heat ‘n’ Cool. The low running cost of heat pump and air conditioning systems makes these units the preferred option for many of Davies’ commercial clients, and we recommend the world’s number one heat pump manufacturer, Daikin.

The Davies team have extensive knowledge of the most reliable and cost effective solutions to suit the specific requirements of retail premises, offices and stores. 

Davies can also take care of Building Warrant of Fitness (BWOF) work and compliance for all Heating and Ventilation systems.

HVAC Installation

Being a full service HVAC company, our engineers are design and build specialists working on projects in Dunedin, Otago, and throughout the South Island. Davies specialise in the design and installation of  large HVAC systems, large multi heat pump systems, ventilation systems and large rooftop heat pump systems for office blocks and large stores. We also specialise in commercial tendering working off consultant plans to suit. Davies are registered for the Design of HVAC systems with all Building Authorities in the South Island. Davies can take care of Design, Installation and Compliance as required for HVAC and Central Heating projects.

When we first started, hot water and steam boilers constituted a large part of our business, and although they are now less popular, Davies can, when required, install and service boilers.

Using a variety of fuels to heat commercial buildings, and institutions such as rest homes, schools, and workshops, we are a preferred provider of maintenance and repairs to Otago’s boiler heating systems.

Davies specialise in swimming pool heating solutions and filtration systems.

Warmed air furnaces are still used in some environments. They offer a low-cost heating solution for large spaces such as halls, gymnasiums and churches.

By law, local councils are required to check and verify that commercial premises which are being built or altered comply with the current building code governing ventilation systems. Davies are registered to both build and design ventilation systems for commercial premises.

Davies can also supply and install commercial kitchen ventilation and cooker hoods, as well as ventilation systems for toilets and offices in commercial and industrial settings. We can also provide fume and dust control systems, and offer maintenance for spray paint booths.
