We now have branches in Auckland and Christchurch and have completed over 1200 large scale projects all across New Zealand.

Some equipment problems can DOUBLE operating costs without reducing comfort & usability.


Up to 80% of all refrigeration compressor failures could be eliminated if the problems that lead to the failure were corrected in a timely manner.

A refrigerant undercharge of only 10% can increase operating costs by almost 20%. If it must be added every year, there is an expensive leak that should be repaired.

A dirty evaporator, condenser and blower could increase refrigeration equipment electrical usage by 50% or more.

Just 1/100th of an inch of dirt or film on an evaporator coil can reduce its efficiency by 5%.. Unrepaired small problems can lead to very expensive repairs.
