I have been carrying out an MVHR self installation, my system is an Airflow DV110 with Airplex Pro ducting system. Right from the early design stage to the ordering and installation process, all the staff at Solarcrest inparticularly Eliot and Nathan have displayed absolute product and installation knowledge always answering any questions I had. Having a little knowledge of MVHR systems I found Solarcrest during my research stage to offer accurate and unbiased advice only offering what was best for my project. I also found my system estimate to be very competitively priced. I highly recommend Solarcrest.
