Commercial Air Conditioning in Grafton
Shops, offices and workshops — sized on occupancy and heat load, not floor area.
Commercial air conditioning is a different design problem to domestic, and treating it like a big house is how businesses end up with a system that cannot cope by eleven on a January morning. Occupancy, equipment heat, door traffic and hours of operation all change the calculation. We do commercial work across Grafton, South Grafton's commercial strip and the Lower Clarence.

Why commercial sizing is different
A domestic calculation is mostly about the building — volume, glazing, insulation. A commercial one has to add everything happening inside it.
- People. Every person in a space is a continuous heat source. A cafe with thirty customers is a substantially different load to the same room empty.
- Equipment. Commercial kitchens, workshop machinery, server racks, display fridges and lighting all dump heat into the space continuously.
- Door traffic. A retail door opening every ninety seconds through a Grafton summer afternoon is a real and often overlooked load.
- Hours. A system running twelve hours a day, six days a week, is doing several times the work of a domestic system. Duty rating and serviceability matter far more.
Get this wrong and it shows up as a system that copes in the morning and gives up in the afternoon — which is exactly when your customers are in.
What we install commercially
Ceiling cassettes for retail and office space — four-way discharge, unobtrusive, good where there is a suspended ceiling.
Ducted systems where there is ceiling space and the layout suits zoning.
High-wall and floor-standing units for workshops and back-of-house, where robustness matters more than appearance.
Most commercial work is three-phase, which is a good thing — better efficiency and better load balance. If your premises is single-phase and needs three, that is Level 2 work we can do ourselves rather than bringing in another contractor.

Frequently asked questions
Do you do commercial air conditioning in Grafton?
Yes — shops, offices, workshops and light industrial across Grafton, South Grafton and the Lower Clarence. Commercial quotes include a proper heat-load assessment.
How is commercial sizing different from domestic?
It has to account for occupancy, equipment heat, door traffic and operating hours, not just the building. That is why a system sized like a house fails on hot afternoons.
Can you upgrade my premises to three-phase?
Yes. That is Level 2 ASP work on the supply side plus switchboard work on yours, and we are accredited for both.
Do you offer servicing contracts?
We can set up a scheduled servicing arrangement. For a system running long hours it is genuinely worth it — unplanned failures are far more expensive than planned maintenance.
Byron Ryder and his team at Ryder Air and Electrical are straight up brilliant. I have had two jobs done by Byron, and both were carried out perfectly. Our farm is 35km out of Grafton and Byron didn't have any problem both times in sorting it out for us.
A wonderful job installing my air conditioner. Left the site spotless and clean, would highly recommend. A very friendly manner and easy to talk to while also being professional.
Provided me an onsite quote and was able to do the work in a timely manner. Cleaned up the work site and did a very clean install on a split system for me. I will be using and recommending in the future.
