HVAC Services in Hershey, PA

Often not. In Hershey's older planned housing we measured a converted duct system delivering strong airflow downstairs and almost nothing to two upstairs bedrooms — high static pressure, an undersized upstairs trunk and no upstairs return at all. Enlarging the trunk where it was accessible, adding a return and sealing the plenum let the existing equipment handle both floors. A second system would have worked too, at several times the cost and with a second set of maintenance obligations.

It helps a lot diagnostically. The early planned housing here was built to similar specifications in similar eras, so the systems and the failures repeat. Once we have solved a problem in one house of a given type, we largely know what to expect in the others — which makes both the diagnosis and the quote more accurate.

Project work and referrals, not routine response. At forty to forty-eight minutes we are honest that closer shops will reach you faster in an emergency. Where we add value is a stubborn distribution problem or a comfort plan that needs measuring rather than guessing.

The same one as in Carlisle's converted houses: duct runs never designed for cooling airflow and returns that were never expanded when rooms were added. It shows up as one floor working and the other not, and it is a distribution problem wearing an equipment costume.

It gives the second floor a path back to the equipment. With every return downstairs, the upstairs is pressurised slightly by supply air with nowhere to go, so conditioned air leaks out through the building envelope instead of circulating. Adding a properly sized upstairs return frequently drops the summer temperature difference between floors by several degrees, and it costs a small fraction of the second system that difference usually gets blamed on.

By measuring total external static pressure, which takes a few minutes and requires no demolition. If the reading is well above what the equipment is rated for, the ducts are the constraint, and new equipment installed onto them will run into exactly the same wall. If the pressure is reasonable and the house still will not hold temperature, the equipment or the load calculation is where to look. We take the reading first and show it to you.
