We specialise exclusively in [heat pump installation](/services/heat-pump-installation) and [air conditioning](/services/domestic-air-conditioning). Not boilers. Not plumbing. Not general maintenance. That singular focus means we see more heat pump faults in a month than most general engineers see in a year. When your system develops a complex refrigerant circuit fault or a defrost cycle failure, we've likely already solved that exact problem for another customer in your area. Based in [Basingstoke](/areas/basingstoke), we serve homeowners and businesses across [Hampshire](/areas/hampshire), [Berkshire](/areas/berkshire), [Surrey](/areas/surrey) and [Wiltshire](/areas/wiltshire). Our clients include domestic properties with single-split systems, commercial premises with multi-zone VRF installations, and swimming pool owners who rely on their [pool heat pumps](/services/swimming-pool-heat-pump-repair) year-round. Every job gets the same treatment: thorough diagnosis, transparent pricing, and work completed to a standard we'd accept in our own home. We don't upsell parts you don't need. We don't quote for replacements when a [heat pump repair](/services/heat-pump-repair) will do. And we don't disappear after the invoice is paid — every job includes a follow-up to confirm the system is performing as expected. ## Our Standards Are Non-Negotiable Every engineer at Appian Heat Pumps holds current F-Gas certification and is trained to work across all major heat pump and air conditioning brands — including Mitsubishi Electric, Daikin, Vaillant, Samsung, LG, and Panasonic. We maintain REFCOM registration, carry full public liability insurance, and follow manufacturer-specified procedures on every job. Our service philosophy is straightforward: diagnose accurately, explain clearly, fix permanently. We don't believe in temporary patches or return visits for the same fault. When we hand you back your system, it works — and it stays working. We guarantee all workmanship. If a repair we've carried out develops the same fault within the guarantee period, we return and resolve it at no additional cost. That guarantee exists because we rarely need to use it — our first-time fix rate exceeds 95%. F-Gas certified and REFCOM registered Full public liability insurance on every job 95%+ first-time fix rate Manufacturer-trained across all major brands ## Our Work in Pictures ![Mitsubishi Ecodan air source heat pump installed on concrete plinth outside a residential property in Hampshire](/assets/work-1-yCIVMH7-.jpeg) ![Ecodan heat pump outdoor unit with pipework lagging and electrical isolator switch](/assets/work-18-BKlkjgjE.jpeg) ![Ceiling cassette air conditioning unit installed flush in suspended ceiling of a commercial office](/assets/work-7-D0nsJOwO.jpeg) ![Refrigerant manifold gauges connected during heat pump commissioning and pressure testing](/assets/work-19-BKdzfXzA.jpeg) ![Heat pump plant room with hot water cylinder, buffer tank, and hydraulic connections](/assets/work-8-CLlbe1Wp.jpeg) ![Split air conditioning outdoor condenser unit mounted on wall brackets at a domestic property](/assets/work-2-BWDRpBxC.jpeg) [View all heat pump and air conditioning projects →](/our-work) ## Measured by Results, Not Promises 15+ Years Experience 2,000+ Jobs Completed 2hr Avg Response Time 100% Workmanship Guarantee ## Ready to Work With an Engineer Who Gets It Right?
