"I have always found HPAC to have carried out the work detailed in their Housing New Zealand contract with the utmost integrity. Their knowledge of heat pump air conditioning systems is expert and they have been able to provide technical advice whenever required. They have kept us informed of any equipment or work adjustments before proceeding. Their relationship with our tenants has been of the highest professional standard and their tenant and staff education on heat pump operation has been excellent. HPAC has phoned each tenant individually to organise an installation date or an assessment and has been happy to deal with any user problems that have arisen."
