Our experience with Craig has been outstanding. He replied to my enquiry quickly and was kind enough to attend the same day to diagnose our swimming pool heat pump issue.This was diagnosed quickly and repaired the same afternoon. Craig has since been back to run a full annual service and we will be using his services for all our heat pump needs.I would highly recommend Appian Heat Pumps to anyone looking for a professional, competent engineer. I award 10/10

Called Craig when we had an issue with our heat source pump. Came around quickly and diagnosed the issue giving recommendations on parts and dealing with the warranty.When spares arrived, Craig fitted, tested and got everything up and running. Brilliant service.Would highly recommend Appian and Craig.

Appian replaced a 15 year old heat pump for my home. Their quote was very competitive and the work completed quickly and professionally. The heat pump is working well and they came back a few weeks after the install to complete some final bits of work and ensure it is running efficiently. I highly recommend them for anyone who needs a heat pump install or maintenance.

Actually 5 stars not enough. ASHP not working as original installers had not made sure no air in the system. Craig came out and fixed everything efficiently on a Sunday morning. THANKS!
