Very impressed with the company. The installers were very good and helpful. Everything was explained and easy to understand.
Thank you Celtic Green Energy for sending Chris to service my Samsung Gen 6 ASHP. I will always use this company for my ASHP in future. Chris was so thorough , efficient and tons of patience dealing with all my many questions and explaining everything. He sorted my settings out and for the first time since having the pump fitted I feel I can relax and stop worrying constantly about the running of my ASHP. I would recommend this company(especially Chris) to anyone whether requiring a service or an ASHP installed. Great customer service too.
We had a complete installation of a central heating and domestic hot water system, powered from an air source heat pump by Celtic Green Energy, in January last year. It has been up and running perfectly for just over a year, so I called upon Celtic Green to carry out an annual service check and inspection. This was carried out on Tuesday of this week, after waiting for a dry day to service the heat pump which is sited outdoors. This was carried out and everything was found to be running perfectly with no leaks or faults apperent.
Investing in renewable energy can be a minefield of complicated and confusing information with an abundance of bewildering online propaganda. To help address this issue, we offer our customers the opportunity to speak to someone in person about their individual circumstances, whether they own a small terraced house or a large factory.
Our Cross Hands based customer service team can offer you the comfort of local knowledge, professional expertise and friendly customer support.
