When the summer ends and the days grow cooler, you want your air source heat pump to function to its full capacity in order to keep your office premises comfortable and warm.

Here’s how to prepare your air source heat pump unit for the winter months.

Clean or replace dirty filters

The first thing to do is to check the filters in the air conditioning unit. If they’re dirty and clogged with debris, airflow through the unit will be restricted. This means that the unit won’t function to its optimum and could even overheat.

Carefully remove the dirty filter from the unit following the directions in your manufacturer’s handbook. Vacuum the dust and debris from the filter using the soft brush attachment on your vacuum cleaner hose. If the end result is a nice, clean filter, replace it in the unit using the directional arrows embossed on the filter for guidance. If the filter still looks grimy, replace it.

It’s a good idea to routinely clean or replace air conditioning unit filters twice a year to keep the unit running sweetly.

Condenser housekeeping

The condenser for your unit is typically located outside. Remove any accumulation of debris and fallen leaves that have gathered around the base of the condenser. Check that the drain is clear and free from obstructions.

Your next task is to inspect and clean the condenser coils. Invariably, dust and dirt find their way inside the condenser during the course of the year and the coils can become clogged-up.

To clean the coils, first, remove the side and top panels from the condenser unit. Put the screws in a safe place while you’re working so that they don’t get lost. For this job, you can use a special refrigerator coil brush which you can buy either from a good DIY store or directly from the air conditioning unit manufacturer. Alternatively, just use your vacuum cleaner’s soft brush attachment. Carefully clean the coils, working from the outside of the unit. Finish off by vacuuming to get rid of any residual debris from the insides of the coils.

Test the unit

Once you’ve finished working on your unit, remember to test it. It’s extremely frustrating to carry out the maintenance work a few weeks before the unit is needed, only to find that there’s a problem when you actually turn it on!

Your air source heat pump should now run smoothly. If there’s a problem, contact us today – we’ll be happy to take a look.

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!
