Air Source Heat Pump Annual Service
Job location: WS13
"First contact with an ASHP engineer since installation. Explained the principles which I thought I knew (my knowledge incomplete!) and gave tips on its operation too. Well pleased - a non-functioning system now operating properly. I'll be calling on him again next year! Also recommending him to my family over in his local area."
