Is there a legal frequency to having a buildings air con serviced / maintained? Obviously most companies that carry this out suggest annually. But is this a legal requirement?

If anyone can point me to any particular legislation ACOP etc that details the legal stance I would appreciate it.

NB we intend to do it, but want to extend the period initially to put it in a better part of the year (take this back a few months and bring forward heating service – as it is same company)

Thanks for any help

Chris

Thanks, I had just found that myself, but it appears to be about energy efficiency, more than Health / Environmental requirements.

But yes, there seems to be a requirement for other testing which I did not know about, so made a copy for bedtime reading. 

I was more thinking of the regular maintenance / servicing side of things.

Cheers

Chris

Hi again Chris

I don't think there are any legal requirements on servicing frequencies, simply inspection frequencies (as they apply to F-gases).  If you require some more bedtime reading, try the below.. :-)

Whilst it doesn't specifically say "AC" you may want to look at L8 on legionella as this is a water system.

Aircon is almost universally a closed 'dry' system, often without water as the medium under pressure.  Even where it does use water there is no means of droplet generation or release so the aircon itself is rarely a cause for concern with regards legionella.  The only intended releases are cold air at one end and hot air at the other. ;)  I'm good at one of those myself.

Some aircon systems have a wet heat rejection system associated with them ie. a cooling tower/evap condenser/adiabatic.  If that's what you've got then L8 standards are definitely in play!

Thanks Elfin Davy

According to that document which I scanned through, the frequency is determined by the qty in the system for leak testing. However, the thresholds were, 3, 30,300 kg of refrigerant and is now 5, 50, 500 tonnes of CO2e!

Ok it is R410a and we have 3.9 kg of it and R410a has a Global warming potential of 2,088 so 3.9/1000 then  x 2088 = 8.1432 tonnes of CO2e

Which according to that document is in the range 5 to 49.99 tonnes, which is once every 12 mths

Bum :o), that’s not the answer I was hoping for.

Thanks to all for their help

Now lets go upset the bean counter

Chris
