Air Conditioning & Ventilation FAQs
Positive Input Ventilation FAQs
Positive Input Ventilation (PIV) systems help manage indoor humidity by improving airflow and reducing excess moisture within the property. By lowering humidity levels, they can significantly reduce the conditions that allow condensation and mould to develop.
However, PIV addresses moisture and ventilation issues rather than structural problems. If mould is caused by leaks, insulation defects or other building faults, these will need to be resolved separately.
PIV systems are designed to operate quietly and are typically installed in the loft space, which helps minimise any noticeable sound within the home.
When correctly installed and set up, the unit runs at a low sound level and is generally unobtrusive during normal operation.
Positive Input Ventilation (PIV) systems help manage indoor humidity by introducing a steady supply of fresh, filtered air into the home. This continuous airflow helps dilute moist air and reduce the build-up of condensation.
By improving overall ventilation, PIV systems can lower excess humidity levels and support a drier, more comfortable indoor environment.
Air Con Installation FAQs
The cost of installing air conditioning varies depending on factors such as the size of the unit, the layout of the property and the distance between the indoor and outdoor units.
As a general guide, a single-room installation for a space of around 15m², with pipework runs of up to 6 metres, typically starts from £999 plus VAT.
For larger rooms, longer pipe runs or more complex installations, costs will vary. A site survey allows us to assess your property properly and provide an accurate, no-obligation quote.
For most single-room installations, we typically allow one full day to complete the work. This includes fitting the indoor and outdoor units, connecting pipework, testing the system and commissioning it correctly.
Larger systems or more complex installations may take longer, which we’ll always confirm following a site survey.
Modern air conditioning systems are designed to be highly energy efficient. Many of the systems we install carry high efficiency ratings, including A+++, and use inverter technology to regulate energy use rather than running at full power constantly.
When correctly sized and installed, air conditioning can be a cost-effective way to heat and cool a space, helping to manage energy consumption and reduce both running costs and carbon emissions.
With UK summers becoming increasingly warm, air conditioning can be a worthwhile investment for both homes and businesses looking to maintain comfortable indoor temperatures.
Modern air conditioning systems do more than provide cooling. They can also deliver efficient heating, allowing you to warm individual rooms during colder months without relying on whole-house heating.
In addition, air conditioning can help manage humidity levels and improve indoor air quality, reducing condensation and lowering the risk of mould in the home.
While it may be possible to fit certain parts of an air conditioning system yourself, installing a complete system is not recommended without the correct training and qualifications.
Air conditioning systems use refrigerants regulated under F-Gas legislation, meaning certification is required to legally handle, install and commission this type of equipment. Incorrect installation can lead to poor performance, leaks or damage to the system.
Modern air conditioning systems also use refrigerants that are flammable, making specialist tools, safety procedures and experience essential. For these reasons, professional installation is the safest and most reliable way to ensure your system operates efficiently and complies with current regulations.
Modern air conditioning systems are designed to distribute air efficiently, meaning placement is more flexible than it used to be. However, positioning still plays an important role in achieving balanced airflow and consistent comfort.
In most cases, installing the indoor unit in a central position within the room helps ensure even air distribution. Factors such as room layout, ceiling height and how the space is used also influence the best location.
Choosing the right type of unit is just as important as positioning. During a site survey, we assess both to ensure your air conditioning system performs efficiently and suits the space.
Air Con Servicing & Repairs FAQs
Yes. All of the manufacturers we work with provide warranties on their air conditioning units, typically ranging from 3 to 5 years, depending on the system installed.
In addition to the manufacturer warranty, we also provide a 12-month workmanship guarantee on our installations, giving you added reassurance that your system has been fitted correctly and professionally.
If you ever experience an issue, please contact us for advice on warranty coverage and the appropriate next steps.
We diagnose and repair a wide range of air conditioning faults, from minor electrical issues to more complex component failures. This includes repairs such as:
PCB (printed circuit board) replacements
Compressor faults or replacements
Refrigerant leaks and system recharges
Fan motor and airflow issues
Sensor and thermostat faults
Electrical and control system problems
Following a full inspection, we’ll confirm the fault and recommend the most practical repair solution.
During a routine air conditioning service, our engineers carry out a series of checks to ensure the system is operating safely and efficiently.
This typically includes:
Cleaning or replacing filters
Inspecting components for wear or damage
Checking refrigerant levels and testing for leaks
Inspecting electrical connections
Testing airflow and system performance
Ensuring controls and thermostats are functioning correctly
Regular servicing helps maintain efficiency, improve air quality and reduce the risk of unexpected breakdowns.
Whether a repair is worthwhile depends on the age of the system, the nature of the fault and the overall condition of the unit.
If the system is relatively modern and the issue is minor, repairing it is often the most cost-effective option. However, if the unit is older, inefficient or experiencing repeated breakdowns, replacing it with a newer, more energy-efficient model may prove better value in the long term.
During our assessment, we’ll explain the condition of your system and provide honest advice on whether repair or replacement is the most practical solution.
Air conditioning systems contain refrigerants that are regulated under F-Gas legislation, meaning only certified engineers are legally permitted to handle and repair them.
Attempting repairs without the correct qualifications, tools and experience can lead to further damage, safety risks or voided warranties. Even seemingly minor faults can involve electrical components or pressurised systems that require professional attention.
For safety, compliance and reliable performance, air conditioning repairs should always be carried out by a qualified engineer.
The cost of repairing an air conditioning system depends on the type of fault, the parts required and the overall condition of the unit.
Minor issues such as electrical faults or blocked filters are typically less expensive to resolve, while more complex repairs involving compressors, circuit boards or refrigerant leaks will cost more.
Following an on-site assessment, we’ll provide a clear, no-obligation quotation outlining the recommended repair and associated costs, so you can decide how you’d like to proceed.
Yes. If your system has lost refrigerant due to a leak, it may require a regas or recharge.
However, refrigerant does not get “used up” under normal operation. If levels are low, this usually indicates a leak. In these cases, we first carry out a full inspection to locate and repair the fault before safely recharging the system.
All refrigerant work is carried out by REFCOM certified engineers in line with current F-Gas regulations.
