FAQs
What makes your whisper-quiet heating and air-conditioning units different from standard systems?
Our whisper-quiet range uses variable-speed inverter compressors, acoustically insulated cabinets, and vibration-dampening mounts that keep operational sound levels as low as 19â24 dB(A)âquieter than a library. Standard split systems typically run at 40â55 dB(A). The advanced electronics modulate the fan and compressor speeds precisely to the load, so the unit rarely has to ramp up to full power, drastically reducing both noise and energy consumption.
How loud will the unit be once installed in my Harrogate home?
In real-world conditions you can expect indoor sound levels comparable to a gentle whisper (â20 dB(A)) and outdoor condenser levels around 42 dB(A) at one metre. For context, normal conversation is about 60 dB(A). Because we site the outdoor unit away from bedroom windows and use anti-vibration pads, most customers canât hear the system running at all inside their propertyâeven at night.
Do I need planning permission or special consent to install an air-conditioning or dehumidifier system in Harrogate?
For most domestic properties, our systems fall under âpermitted developmentâ as long as the external condenser is below 0.6 mÂł, located more than one metre from the property boundary, and not on a listed building or within a conservation area. If you live in central Harrogateâs conservation zones or in a listed property, we will help you obtain Listed Building Consent and/or planning approval. Commercial premises may require separate consent from Harrogate Borough Council.
What are the advantages of adding a whole-home dehumidifier to the system?
Yorkshireâs climate can produce year-round relative humidity above 70 %. High indoor humidity encourages mould, dust mites, and that clammy feeling even at moderate temperatures. A dedicated dehumidifier integrated with your HVAC system keeps RH in the optimal 40â55 % range, improving comfort, protecting wooden floors and furniture, and preventing condensation on windows. Lower humidity also lets you set the thermostat a couple of degrees higher in summer or lower in winter, saving up to 10 % on energy bills.
How long does installation take and will my home be disrupted?
A typical three-bed home with one or two indoor wall units plus a whole-home dehumidifier can be completed in 1â2 days. We pre-survey to plan pipe runs, electrical connections, and condensate drainage, minimising wall penetrations. Our engineers use dust sheets and clean-room vacuums, and we remove all packaging and old equipment. Youâll have at least one fully qualified F-Gas-certified installer on site at all times, and we give a full hand-over demonstration before we leave.
What warranty and maintenance do you provide?
All whisper-quiet units and dehumidifiers come with a 5-year parts and labour warranty when we carry out annual servicing. The service includes refrigerant pressure checks, coil cleaning, filter replacement, and a full performance test. Remote monitoring is available; if the system senses an abnormality, we receive an alert and can often resolve issues before you notice them. Extended 10-year warranties are available for homeowners who enrol in our Gold Maintenance Plan.
