How to Prepare for a TM44 Air Conditioning Inspection: A Quick Guide for Business Owners
If your building has an air conditioning system with a combined output over 12kW, you’re legally required to have a TM44 inspection every five years. But what should you expect, and how can you make the process as smooth as possible?
At DCEC Ltd, we’ve carried out inspections across countless sectors, and we know that a little preparation can go a long way. Here’s how to get inspection-ready.
1. Know Your System
Before your inspection date, it helps to have a clear understanding of the layout and size of your air conditioning system. Locate your system manuals, maintenance logs, and any previous TM44 reports. These give your assessor valuable context and may help streamline the process.
2. Make Access Easy
Inspectors will need access to key parts of your building and HVAC systems. This may include roof spaces, plant rooms, or ceiling voids. Make sure someone onsite knows where everything is and that keys or access permissions are sorted in advance.
3. Don’t Worry About Perfection
The TM44 inspection is designed to help, not to catch you out. We’re not here to criticise, we’re here to highlight areas for improvement so you can save energy and stay compliant.
4. Keep Your Maintenance Records Up to Date
Well-maintained systems are generally more efficient. Having up-to-date service records shows your commitment to good practice and gives your assessor better insight into how the system has been running.
5. Book With a Qualified Provider
It’s essential to use an accredited and experienced assessor. At DCEC Ltd, our inspections are carried out by CIBSE-registered engineers and Government-accredited energy assessors, so you can be confident your report is fully compliant and high quality.
What You’ll Get After the Inspection
After we’ve completed the assessment, you’ll receive a full TM44 report, including:
-
A summary of your system’s current condition
-
Insights into energy efficiency
-
Recommendations for improvement
-
Compliance documentation
