What People Say

“pH7 Mechanical were called in to make all the electrical and plumbing connections to the new Dantherm air handling system servicing the White House pool building. They met all timing and appointment times/dates, were totally competent in connecting the Dantherm unit to such an extent that the Dantherm engineer was very complimentary and implemented other improvements to make the system run more efficiently.

Whilst on site Ivo Jovanovich (Director) demonstrated a full knowledge of not only the air handling unit but everything related to the swimming pool operation. We would highly recommend PH7 to anyone considering installing a pool and the mechanical requirements related to an installation.”
