Brian, Once again thank you for going above and beyond with everything you did to resolve our problem. I’ve attached a jpg, which I think you’ll find rather satisfying, before we went to bed last night, the system had achieved this. We were beautifully toasty and warm downstairs with NO electric heater on (this had to be a first in Kate history!!) and upstairs was a lovely cool 69 degrees and no-one overheated all night. The humidity reached 35 percent and all is well in our world! Your care and dedication was really exceptional and we really do appreciate the time you took to not only explain everything to us but the honesty with which you conducted your business. On that note, we look forward to passing your details on to as many people as we can as our preferred specialist in the heating and air-conditioning field.
