Maintenance

Commercial

Protect your assets and reduce your operating costs.

All too often, planned preventative maintenance of equipment is neglected, it might be viewed as an easy means of reducing annual expenditure. In reality however, this is a false economy. While the business undoubtedly saves itself these maintenance costs, the unseen costs soon build up. 

 

Initially, filters get blocked, this puts additional strain on the fan motor/s. As the filters become more choked, the volume of air drawn across the heat exchanger drops, this reduces the amount of cooling that the unit can produce. The operating pressures within the system are also reduced from their optimum. 

 

Due to the increased resistance across the air filter, small particles of dust which would otherwise have been trapped by the filter are pulled through and onto the heat exchanger which the filter is there to protect. This reduces the efficiency of the coil, because the dust & debris effectively begins to insulate the previously efficient Heat Exchanger.  

 

If left unchecked, the situation continues to compound itself leading to overheating of motors, and in severe cases, damage to the compressor (the heart of the system and ultimately the most costly component to replace). A failed compressor in a system of medium age (particularly one with clogged heat exchangers) can often prove to render the system beyond economic repair leading to the need for major capital expenditure to install a new system. Time and time again, we have had experience of replacing systems which, had they been properly cared for could have provided many additional years of continued useful service. 

 

A common fault with Air Conditioning systems is a water leak – as a result of the cooling process, moisture is removed from the air being cooled. This moisture forms condensation on the cooling coil which then collects in a drip tray below.  From here, the condensation must be discharged to a drain. If there is insufficient height/ space to run the condensate in a gravity drain, it will need to be pumped. There are a variety of different types of pump available, some are more reliable than others. Unfortunately, it is inevitable that most pumps will fail at one time or another, however routine maintenance and treatment of the unit drip trays can significantly extend the life of a pump.

 

An important element of the planned maintenance of Air Conditioning Systems is to undertake a refrigerant leak check on the system and to assess if the refrigerant charge is correct. Not only is this important to ensure that systems operate efficiently without risking compressor damage (which results when a system runs short of gas), but this check also ensures that your company is compliant with F Gas regulations see F Gas Compliance section for more details.

A well maintained Air Conditioning and Ventilation system ensures a comfortable working environment for your staff. Not only does this promote a feeling of well-being, but studies have shown that there is a direct link between temperature in the workplace and staff productivity

 

 

Residential

While the benefits of regular maintenance as detailed in the Commercial section are also relevant to systems in the domestic or residential environment, the reality of comfort cooling within homes in Britain is that the volume of running hours per year will be significantly less than in commercial premises. This is normally due to the increased concentration of people within the work environment, along with the fact that generally there is more heat producing equipment within a business premises whether it be IT type equipment or plant and machinery within a production environment.

 

While all the reasons for regularly maintaining systems in commercial premises still apply in the domestic environment, in the home, often one service per year is sufficient to ensure that the system is in a good state of repair.
