DetailsWhy Legacy Air
A trades service that behaves like engineering.
Legacy Air is Sandton based and works across greater Johannesburg. The difference is simple: we measure, we document, and we stand behind the numbers we quote.
Heat pumps are all we do
Air-source systems are our speciality, not one line on a long list of plumbing services. That focus is why diagnosis and sizing land right the first time.
Sizing before selling
Every job starts with an assessment. An undersized unit never stops running and never catches up — which is exactly how heat pumps get blamed for high bills.
Fixed, itemised quotes
Unit, labour, materials and electrical work listed separately and priced in writing before work starts. If we find something extra, you hear it from us first.
No-hot-water calls first
Cold showers get priority. We tell you honestly when a technician can be with you, and we carry common spares to finish most repairs in one visit.
Homes and commercial scale
From a townhouse geyser conversion to plant rooms across an estate, office park or guest house — with the records trustees and auditors expect.
Tested before we leave
Every installation and repair is run under load and measured before handover, and you get a written note of what was found and what was done.
How it works
From first call to first hot shower
Tell us what is happening
Call, WhatsApp or send the quote form. We ask what the system is doing and what you need from it.
Site assessment
We measure the installation, check the cylinder or pool and confirm what capacity the property actually needs.
Written quote
A fixed, itemised quote with unit, labour and materials separated, so you can compare properly.
Install or repair
Work happens on the agreed date, with hot water restored the same day wherever it is possible.
Aftercare
Commissioning, a walkthrough of the controls, and the option of an annual maintenance plan.
