Server room cooling failure, treated as an outage risk.
Room temperature climbing? Call now, then shed load while we travel.
Call 07940 953486 nowA comms room does not get uncomfortable, it gets expensive. Equipment throttles as inlet temperatures rise, then it starts shutting itself down, and the cost of that has nothing to do with the price of the repair.
Continuous duty cooling wears differently to comfort cooling. There is no overnight recovery, no quiet season and no natural pause in which a filter can catch up, so intervals set for an office are simply wrong for a room full of racks.
The other recurring problem is redundancy that only exists on paper. Two units installed as duty and standby are only redundant if the changeover actually happens, and we find plenty of pairs where one unit has quietly done all the work for two years while the other seized.
Where a room is genuinely critical, the sensible package is a proved changeover, a shorter service cycle and a high temperature alarm that reaches somebody at three in the morning. None of it is expensive next to one unplanned outage.

FAQs
Frequently asked questions
Our server room is overheating. What do we do right now?
Get the heat out and the load down. Prop the door if security allows and put a temporary fan moving air out of the room, shut down anything non essential, and check the outdoor unit is running and not obstructed. Then call. Kit throttles before it fails, so a room that is climbing has already started costing performance.
Why do server room units fail more often than office ones?
Because they never stop. An office unit works eight hours a day for four months of the year; a comms room unit runs every hour of every day. Filters block faster, bearings wear sooner and a small refrigerant loss shows up much more quickly when there is no overnight recovery period.
Should a server room have two units?
If the room matters, yes. Duty and standby pairs on an automatic changeover mean a single failure is an inconvenience rather than an outage, and it also lets each unit rest. Where a room has a single unit and no redundancy, we will say so in the report rather than leave you to discover it during a failure.
Our two units are both running all the time. Is that right?
Usually not. A duty and standby pair should alternate, and if both are running continuously either the changeover has failed or the room load has outgrown one unit. Both are worth knowing before the hot week arrives.
Can you add monitoring or alarms?
Yes. A temperature alarm that emails or texts on a high limit is inexpensive and turns a silent overnight failure into a phone call. For unmanned comms rooms it is the single most useful thing you can add.
Do you cover this on a maintenance contract?
It is one of the assets we rank as critical. Comms room cooling is typically visited more often than the rest of a site's air conditioning, with changeover proved at every visit and filters on a shorter cycle.

Close-control cooling for server and comms rooms
Server rooms need cooling that runs continuously, holds a tight temperature band and tells someone immediately if it fails — comfort cooling logic doesn't apply.
Cooling for offices, server rooms and shops: what suits each
These three spaces get treated as one problem far too often, and it is why so many small commercial installations disappoint.
