EAJ installed a multi-split system across our flat and the difference is incredible. The team arrived on time, kept everything spotless, and walked us through the controls. Highly recommend for anyone in London looking for a proper job.

Our aircon stopped cooling right in the middle of a heatwave. EAJ came out the next morning, diagnosed a refrigerant leak, and had it running the same day. Fair pricing and genuinely knowledgeable engineers.

Booked them for an annual service after a friend's recommendation. Thorough, tidy and honest — they flagged one small issue and fixed it on the spot rather than upselling us. Will use again next year.
