We begin by evaluating every component of your air conditioning system — assessing its condition, control strategy, and sizing against the actual requirements of the building.
Our inspectors then identify practical ways to reduce energy consumption, improve performance, and extend equipment lifespan.
Following the visit, you’ll receive a clear, detailed TM44 report written in plain English.
It outlines how your systems are performing, highlights opportunities for improvement, and provides a compliant certificate lodged with the Government’s Landmark Registry — valid for five years.
