"The team at Walsh & Son were phenomenal. They explained the whole heat pump process clearly, designed a system that works perfectly, and the installation was spotless. Our house has never been this warm."
James T.

"Transformed our heating completely. The low-temperature radiators they recommended keep the house so comfortable, and our running costs have dropped significantly. True professionals."
Sarah M.

"I was nervous about switching from gas to a heat pump, but Walsh & Son handled everything, including the Boiler Upgrade Scheme grant application. The workmanship is incredibly neat."
David L.

"Fitted our air conditioning just before the summer heatwave. The units are virtually silent and the installation was completed in a day with zero mess. Highly recommended."
Emma W.

"We needed a new boiler and hot water cylinder. Walsh & Son provided honest advice, didn't try to oversell, and the installation was completed on time with immaculate pipework. A genuinely professional service."
