If your business workshop contains a lot of heat-generating machinery and plants, a reliable and efficient air conditioning unit is essential for your comfort and for that of your workforce. Although it may seem like a time-consuming hassle, it’s well-worth taking the time to clean your outdoor air conditioning unit each year, before the summer. This will help the unit’s efficiency, making it more reliable and cheaper to run; it should also last longer too.

You could choose to tackle this job yourself or you may prefer to ask your local air con maintenance technician to do the work for you.

Cleaning your business’ air conditioning unit

First of all, switch off the power to the unit at the appliance shut-off box. This is usually found near to the outdoor unit. If you can’t locate the appliance shut-off box, you can turn off the power at the circuit breaker, which you will find located in the main air conditioning unit control panel.

With the power switched off, remove the protective case from the air conditioning unit. To do this, simply unscrew the fixings and carefully lift the casing off. Be sure to put the screws somewhere safe so that they don’t get lost while you’re working.

Now vacuum the air conditioning unit’s condenser fins, using the soft bristle brush attachment on your vacuum cleaner. Go carefully, as the fins are fragile and can be easily bent if you’re too heavy-handed. Next you need to clean off any accumulated grime from the fins. To do this, make up a solution of warm water and washing up liquid and place it into a plastic spray bottle. Spray the fins with the solution and then rinse away any dirty water and soap with clean water.

Next, carefully remove any debris, weed or grass growth that may be blocking the coil and disrupting the airflow. You might need to cut back overhanging shrubbery and do a spot of weeding around the unit too. Finally, unscrew the top grille on the unit and prop it open. Vacuum the fan, taking care not to disrupt or stretch the wiring. Replace the grille and the unit’s protective casing.

In summary

These basic cleaning and maintenance tips will help to keep your air conditioning unit working efficiently right through the summer. Although this is a job that you can do yourself, you should also have your air conditioning unit fully serviced annually by an experienced professional.

I can unconditionally recommend Inn-House Technology Ltd as a thoroughly excellent provider of all aspects of domestic air conditioning from initial contact, design development, through detailed site work to contract administration and on to maintenance. I speak as a hard-bitten Chartered Engineer and project manager who has probably seen it all; but Inn-House Technology has restored my faith that there is a British company which does it right to time, cost and quality. The initial site visit was by an experienced technician who has turned his hand to sales and was followed up by a further detailed visit with a staff specialist because the 4-unit multi-split installation is in a high-quality residence so that pipe concealment and silence in operation are crucial – and achieved. The two-man team left home at 0555 to arrive exactly on time for 3 consecutive days fully supplied with all the tools and plant required from their preferred but not exclusive partner supplier – Fujitsu. All indoor debris from numerous drillings was cleaned up as soon as it arose causing negligible dust- even embroidered curtains were kept in place. No shoes were worn indoors. The quality and fit of the pipework, cabling and trunking was exemplary and the indoor units were positioned exactly as specified. Outside, the wall penetrations and resealing of this Passivhaus were accurate and the heat pump connections neatly concealed by a black trunking beside a downpipe. The two installers, Jim and Sam, were professional, knowledgeable, personable, strong, agile and 100% committed to my job – not once stopping for lunch. The back-office handling of the sales, contract, procurement, invoicing and maintenance were each impeccable and the team are clearly loyal to their company which has strong systems to give quick response and confidence to the customer. The whole installation experience was an exemplar of how to run a company well and I have no hesitation at all in recommending Inn-House Technology.

Excellent and Faultless Experience with our Air Con Install. We reached out to I-HT among other Installers in the area, within a couple of hours they had made contact and arranged to visit to provide a quote within the same day. The quote was sent quickly and competitively priced. Lee who visited was very friendly and helpful and provided a good insight into what could be done and how with regards to our property. On install day we had 2 of their team pop out to complete the install and I can't explain enough how polite, friendly and considerate they were. Not only this but they were also very tidy and cleaned up behind them at every step. The day after I also had a follow up call from the office to make sure we were happy. overall 10/10 and can't believe how simple and perfect the install went. Thank you so much and look forward to recommending them to everyone in the future!
