Applying HVCA TR/19 best practice guidelines to maintain high air quality for your staff and customers
Maintaining a clean AHU alongside clean ductwork is essential in removing airbourne pollutants.
I am really happy with the deep clean. The guys were absolutely faultless and I am more than satisfied. They did a fantastic job. Worked flat out and left it looking almost brand new which is a massive achievement considering it hadn't been done for nearly a year. They also left everywhere really tidy after they had finished which is something that doesn't always happen to be honest.

We built a new utility company headquarters on a brown field site, and had a requirement to get all the ducts cleaned prior to commissioning to the TR/19 specification.
PdC took that part of the job from us and owned it totally.
They were completely at home on a major site and were both helpful and pro–active in solving any problems that arose.

Your workforce attended the club today to carry out works as instructed.
If all contractors met their duties with the professional attitude, skill, pride, confidence and levels of communication that the whole team showed today, I would be blessed.
They were faultless/ floorless(sic) in carrying out their duties.
I would be very happy to put on record a reference "SECOND TO NONE".
You can be assured that a contract for any future works is assured.

BS EN15780 specifes the detailed requirements for the cleanliness of newly installed air duct systems.
The level of cleanliness required depends on the system cleanliness class that has been adopted for the project.
Measurements need to be based on a verifiable cleanliness outcome and should use the Preferred Vacuum Test to confirm the outcome of the cleaning process.
| Quality Class | Typical examples | Acceptable dust accumulation level Supply, recirculation or secondary air ductwork |
Acceptable dust accumulation level Extract ductwork |
|---|---|---|---|
| Low | Rooms with only intermittent occupancy | < 0.9 g/m² | < 1.8 g/m² |
| Medium | Occupied rooms including: Offices, hotels and restaurant | < 0.6 g/m² | < 1.8 g/m² |
| High | Laboratories and hospitals | < 0.3 g/m² | < 0.9 g/m² |

Maintaining a clean AHU alongside clean ductwork is essential in removing airbourne pollutants.
Moreover, regular AHU cleaning will increase the efficiency of your unit which translates to savings on monthly heating/cooling energy consuption. This is one cleaning service that undoubtedly pays for itself in energy savings!
According to the Environmental Protection Agency, a buildup of four one-hundredths of an inch of dirt on a heating or cooling coil can result in a 21% decrease in efficiency.
And what is more, the dominant cause of heating and cooling system failure is because of dirt and dust.
HSE regulations require that all mechanical ventilation and air conditioning systems are regularly and properly tested and cleaned.
| Example environment | AHU | Filters |
|---|---|---|
| Rooms with only intermittent occupancy | 24 | 12 |
| Occupied rooms including: Offices, hotels and restaurant | 12 | 12 |
| Laboratories and hospitals | 12 | 6 |

Controlling ducting deposits and monitoring their build up is essential to maintain hygiene standards and reduce fire risks in heating and ventilation systems.
Deposit Thickness tests provide a reliable and quantitative way of measuring the degree of cleanliness of your ductwork, which in turn will help to determine when and how frequently cleaning is likely to be required in order to maintain the quality of the air through your ventilation system.
The TR/19 standard specifically addresses the need to measure the build up of deposits and specified a set of upper limits withing Section 5 based on good practice.
| System Type | Surface Contamination Limits | Test Method |
|---|---|---|
| Extract | Deposit Thickness Test | |
| Re-circulation | Deposit Thickness Test | |
| Supply | Deposit Thickness Test |
