How HVAC supervisor pay ranges in Sierra Leone

Half of all HVAC supervisors in Sierra Leone earn less than 58,798,900 SLL a year, and the other half earn more.

The middle 50% of HVAC supervisors sit somewhere inside that band, which is where the typical reader of this page probably lives.

HVAC supervisor pay by experience in Sierra Leone

Years of experience is the single biggest lever on pay for an HVAC supervisor in Sierra Leone, ahead of education and almost any other single factor. The longer you have been in the role, the more your employer can trust you to handle complexity, mentor others and act independently, all of which command higher pay. The chart below shows how the typical HVAC supervisor salary changes as you move through the career ladder.

  • 0-2 Years
    28,439,500 SLL
  • 2-5 Years

HVAC supervisor gender pay gap in Sierra Leone

The gender pay gap is a stubborn feature of almost every labour market, and Sierra Leone is no exception. Male HVAC supervisors in Sierra Leone earn an average of 59,999,100 SLL a year, while female HVAC supervisors earn around 48,841,700 SLL. That works out to a 23% gap in favour of men, even when comparing people doing the same work.

A pay gap of this size has a real long-term cost. Over a typical thirty-year career it can add up to several years of pay, and it compounds through pensions, retirement contributions and bonus-linked stock. Some of the gap is explained by women being more likely to work part-time, take career breaks, or be steered toward lower-paying specialisations. Some of it is straightforward unequal pay for the same job, which is harder to defend.
