Whisper-quiet Split Units
Whisper-quiet Split Units | Ventilation and Air Quality | Heating and Air Conditioning | Harrogate
Breathe easy in Harrogate with HEP’s whisper-quiet split units, designed to deliver precision heating and cooling without the intrusive hum of conventional systems. Sleek indoor cassettes pair with efficient outdoor condensers to maintain the perfect temperature all year round, all while sipping energy and fitting discreetly into any home or workspace.
Beyond comfort, our engineers build each installation around superior ventilation and air quality, introducing filtered fresh air that removes allergens, odours and excess humidity before they ever circulate. From initial survey to ongoing maintenance, HEP tailors every detail to your lifestyle—so you can enjoy cleaner, calmer air and lower bills with complete peace of mind.
FAQs
How quiet are your split-unit systems compared with traditional air conditioners?
Our premium indoor units operate from just 19 dB(A) on the lowest fan setting—quieter than a library (≈30 dB) and barely above a whisper. The outdoor condenser is also engineered for low-noise performance, averaging 45–48 dB(A) at one metre, so neighbours remain undisturbed. Sound-dampened compressor mounts, variable-speed DC inverter motors, and aerodynamic fan blades all work together to keep noise at an absolute minimum.
Will a split unit provide both heating and cooling suitable for Harrogate’s climate?
Yes. The systems use air-source heat-pump technology capable of efficient heating down to –15 °C and cooling up to 46 °C, comfortably covering Harrogate’s temperature range. In heating mode the COP (coefficient of performance) can exceed 4.0, meaning you get more than 4 kW of heat for every 1 kW of electricity consumed, resulting in lower running costs than electric panel heaters or older gas boilers.
How does the unit improve indoor air quality as well as temperature control?
Each indoor cassette is equipped with a multi-stage filtration suite: a washable pre-filter traps dust and pet hair; an activated-carbon layer absorbs odours and VOCs; and an optional HEPA-grade or plasma ionisation module captures particles down to 0.3 µm, including pollen and spores common in North Yorkshire. Continuous ventilation settings allow you to run the fan independently of cooling/heating to keep fresh, filtered air circulating even at night.
What is involved in installing a whisper-quiet split system in my Harrogate property?
A typical installation takes one full day. The indoor air handler is mounted high on a wall or recessed in a ceiling void, requiring only a 65 mm core-drilled hole for the refrigerant lines, power and condensate drain. The outdoor condenser is sited on a vibration-isolating pad or wall bracket. Because each room has its own sealed circuit, no large ductwork is necessary, preserving older stone or listed interiors common in the area. All work is carried out by F-Gas certified engineers and includes pressure testing, vacuum pull-down, R32 refrigerant charge, and commissioning.
How energy efficient are the systems and what are the running costs?
Models we supply carry an A+++ seasonal energy efficiency ratio (SEER) for cooling and an A++ seasonal coefficient of performance (SCOP) for heating. For an average 20 m² bedroom you can expect annual electricity usage of roughly 270 kWh for cooling and 480 kWh for heating, equating to £95–£175 a year at current rates—often 30–50 % less than conventional electric heaters or portable AC units. The units also qualify for 0 % VAT on domestic heat-pump installations and may contribute toward EPC improvements.
What maintenance is required to keep the unit running quietly and efficiently?
Homeowners should vacuum or rinse the pre-filters every 4–6 weeks and wipe the fascia with a damp cloth. An annual professional service covers refrigerant pressure checks, deep-cleaning of the evaporator coil with non-acidic foaming agents, anti-bacterial drain-pan treatment, firmware updates, and performance optimisation. Regular maintenance prevents coil fouling (which can raise noise and energy use by up to 20 %), maintains healthy air quality, and preserves manufacturer warranties of up to 5 years.
