What is a TM44 Inspection?
A TM44 is a report that assesses the energy efficiency of your air conditioning systems and provides recommendations for how to use them in a more efficient way. The assessor may recommend altering the temperature settings or may recommend replacing some of the systems if they are old or inefficient.
TM44 reports are required by law for any site with systems more than 12kw combined and over 5 years old. For example, if you had 3 x 5kw wall mounted systems installed in 2024 (and had no other units on site), you would be required to have your first TM44 inspection in 2029.
An inspection must be carried out every five years. If a valid TM44 inspection has not been completed there is a fine of £300 per system and an additional £200 fine if the report isn’t submitted within 7 days of request.
Concept Air Conditioning are able to arrange a TM44 inspection, and we will also quote for any recommendations made in the report. Get in touch with our team on 01942 677 348 and we're happy to discuss the requirements for your site.
How often should I maintain my air conditioning?
A well maintained air conditioning system will work more efficiently and will have a longer life-span. The minimum requirement for an air conditioning maintenance is once per year to be F Gas compliant, however this may not be enough for most applications. For domestic properties, once per year may be suitable. But environments such as offices, hairdressers, dentists, industrial units and schools may need between 2 and 4 visits per year.
Concept Air Conditioning provide free surveys to assess your specific requirements a quick guide is below but this may vary depending on your specific site.
A well-maintained system should improve indoor air quality. If the unit is not cleaned or serviced, it may circulate dust, bacteria, or allergens, which could cause discomfort. Another method to avoid feeling sick from the air conditioning unit is to have ventilation within the room from time to time e.g. open windows. If you don’t have any opening windows, consider installing a mechanical ventilation system. Contact us for a free no obligation quote.
If you are concerned about your air conditioning unit not providing comfortable air quality give us a call and we are more than happy to help you over the phone or via a site survey.
Leaks are often caused by blocked drain lines, low refrigerant levels, or failed pumps. A professional inspection by Concept can identify and fix the issue quickly.
As soon as you notice a leak, turn off the unit to prevent water damage to your wall, ceiling or floor. Then give us a call and we’ll send an engineer out to fix the leak or replace the pump.
Unpleasant smells are usually caused by bacteria which comes from damp coils, mould which can occur when a room has high humidity levels or poor ventilation, or dirt inside the system. A deep clean may be necessary to get rid of the smell. Then consider increasing your number of maintenance visits to prevent the smell from coming back.
For cooling, 21-23°C is usually comfortable. For heating, 19-21°C is recommended. When there is a heatwave aim to have the unit set no more than 6-8°C less than outside as this will help to avoid overworking the unit. The ideal setting depends on your personal comfort and energy efficiency goals.
On the coldest days of the year, keep the temperature as low as possible to prevent your unit going into 'defrost mode'. When the unit is in 'defrost mode' it will run on fan only to melt the ice formed on the outdoor coils. This can feel really cold when the temperature in the room is already low. Also consider 'night setback mode' where you keep the unit running overnight on the lowest heating temperature so that the system doesn’t need to work as hard to get the room warm in the morning.
If you are unsure about the setting of your air conditioning unit, give us a call and we will advise of the optimal settings which will suit you.
Most domestic and simple split system installations are completed within one day. Larger or more complex systems like twin, multi and VRF systems may take longer. Speak to one of our projects team members who can advise.
Concept is flexible to meet your needs and work around your schedules. Whether the office is booked for a meeting or you are on holiday, our engineers will always communicate with you to achieve the most efficient outcome which works for you.
Standard air conditioning units recirculate and filter indoor air rather than supplying fresh air. For ventilation solutions, additional systems may be required.
Contact us to arrange a site survey so we can assess the best solution for you.
Yes, we offer free site surveys to assess your space, consult you on your preferences and needs which will help us to design a system that works and works for you.
Our site surveys are free of charge and with no obligation required to commence with the works.
Servicing keeps your system running efficiently, reduces energy costs, improves air quality.
The team here at Concept provide structured and consistent maintenance plans to keep your air conditioning circulating clean air around your premises.
You can carry out simple tasks such as cleaning or replacing filters. However, professional servicing is required for checks on refrigerant levels, electrics, and overall system performance.

Yes, most modern air conditioning systems can do cooling and heating. How it works is when a unit is in cooling mode it removes the heat by pulling the warm air out of your room and blows cool air back in. However, when a unit is in heating mode the unit collects heat from the outside air and transfers it inside into your room.
Contact us and we will provide you with brochures via email and we can discuss the type of unit required to suit your needs.
Modern systems are energy efficient and often cheaper to run than traditional heating methods such as gas boilers, especially when well maintained. A well serviced unit can save 10-30% on energy costs.
Ice on the outdoor coil is usually down to either the temperature setting being too high in heating mode or it can indicate a refrigerant leak. If you see ice on your outdoor unit, turn the unit off to allow the ice to thaw then try using the unit in a lower temperature setting (18-21 degrees in heating mode). If the problem reoccurs, you will need a service call to assess whether there is a refrigerant leak. This will then be followed up by a leak and pressure test quote if there are signs of low pressure in the system.
Signs include frequent breakdowns, high running costs, reduced efficiency, or if the unit is more than 10–15 years old. If you find you are spending a lot of money on repairs, it might be time to replace the system. We can provide a cost to replace the system with just the unit model numbers and a picture of the indoor and outdoor units. If you don’t have these details, give us a call to arrange a free site survey.
