Many small to medium businesses see the advantages of having a pre-arranged service contract or service agreement in place for their heating, plumbing, ventilation and controls (HVAC). It is most common for the HVAC commercial contractor to include planned maintenance to especially mechanical and hydraulic equipment like boilers, pumps, hot water tanks etc.
Although it is possible to find a company each year who will undertake a service, you may find comfort in an agreement to minimise the time and hassle of finding them. This is especially useful in the event of a boiler breakdown, water leak or other commercial heating problem as once in an agreement there is often a reduced cost for callout and responsive action.
The recommended annual works are a short interim service in the colder months, during this service there will be minimal or no down-time and the occupants should notice no changes to the heating or hot water. In the summer when the HVAC equipment is being used less a major service can be undertaken, this usually takes a day or two per plant room and minor parts can be replaced and the boilers, cylinders and pumps can all be fully inspected.
We offer these across Surrey and Hampshire and West London with a focus on Aldershot, Farnham and Farnborough.
An interim service checks the essentials like safety and efficiency, if anything has changed since the main service it will be picked up and can be rectified before it has an impact on the reliability or fuel usage. During the interim service the engineer will:
-Check the flue and boiler visually for any signs of corrosion, the boiler case will be opened but the burner and other components not be removed so there should be no need for seals to be replaced.
-Check and increase/decrease the pressure in the system, if this involves a fault with air ingress or insufficient expansion then remedial works may be required.
-Perform a full emissions check on high and low fire, this is crucial to ensure the boiler is operating with the intended fuel efficiency stated by the manufacturer.
-Operate the controls to find any defective zones, report back on failures.
Manually operate any isolation valves to prevent seizing.
This typically involves a major service in the warmer months during which a full strip down service is undertaken, gaskets are replaced, burners, electrodes and heat exchangers are fully inspected. During the main service the engineer will:
Perform all checks within the interim service.
Remove and inspect the burner/s.
Inspect and clean the primary heat exchanger/s.
Inspect and replace (if applicable) burner gasket, electrodes etc.
Conduct full flow and spillage tests (for open flued appliances).
Conduct the commercial gas safety check (CP17) if necessary and within agreement.
Check through any error codes on the BMS etc.
Test the primary heat water (radiators or uder h) for pH and hardness.
Remove and clean the condensate syphon and check the connected waste is not blocked.
Clean any magnetic or strainer type filters.
Undertake any manufacturer specific service tasks.
Upon undertaking a service or maintenance agreement the heating professional should be given a copy of the asset register, this is a list of all equipment within the building and should give the make and model of the HVAC equipment. If the register is not in place or has been misplaced then an extra amount of time should be given with in the first yearly inspection to create one. An asset register is the first important step to reducing the down-time of a failed component if something goes wrong but you don't know what it is or who made it then the repair time is often doubled. With an accurate asset register and routine maintenance, the risk of time spent with no heating or hot water is greatly reduced.
Any domestic and any commercial property which is open to the public must have in place a safety certificate for the gas (and some other) equipment. This is usually performed during the main service and provides a legal record of each appliance, the gas meter and all gas pipe-work after the meter. It tests for gas leaks and records changes over time.
Not having an annual CP17 gas safety inspection and subsequent certificate can lead to prosecution and will likely invalidate any warranties and insurances.
