Air conditioning provides consistent indoor comfort by cooling and dehumidifying the air, which is especially valuable during warmer months. Many modern systems also offer heating options, making them a versatile solution for year-round climate control. Additionally, air conditioning can improve indoor air quality by filtering out dust and allergens.

Benefits include lower carbon emissions, reduced energy bills, and decreased reliance on fossil fuels. Heat pumps are also eligible for Government incentives, which can help reduce installation costs, making them an attractive choice for eco-conscious homeowners.

Basic maintenance involves cleaning or replacing filters every few months to maintain air quality and system efficiency. Annual servicing by a professional is recommended to check refrigerant levels, clean coils, and inspect electrical components, ensuring reliable operation.

Yes, many air conditioning units come with a heat pump function, allowing them to provide both cooling and heating. This feature makes them a versatile solution for year-round comfort, reducing the need for a separate heating system.

With proper maintenance, air conditioning units can last 10-15 years or more. Regular servicing helps extend their lifespan, keeping them energy-efficient and preventing costly repairs.

I can not rate Walsh Plumbing highly enough. From start to finish the service was smooth, quick and professional. Sales, pricing, fitting, after sales service - all faultless. Such a relief to have had my boiler replaced so quickly and smoothly. Thank you

Fitted in new boiler and took old very large barrel shaped one away! Professional, very good rate and even brought their own hoover and cleaned up after themselves. I would highly recommend

Used Walsh Plumbing to replace my boiler which packed up. They came out literally 2 hours after my boiler stopped working, and 1.5 days later they had installed a new one. Great communication and service I would highly recommend.

Fantastic service. Visited same day to quote and talked us through numerous options. Quick turnover from deciding which option to go with to getting an installation booked. The engineer carrying out the boiler install was very professional, tidy and kept us informed of his progress throughout. Would highly recommend.

I have recently used Walsh plumbing for a service of my boiler and fitting of two new radiators- I couldn’t fault them one bit! Their professionalism throughout was top notch & they were tidy and polite from start to finish. We also provide them with scaffolding when required (just scaffolding Hertfordshire LTD)
