If plumbing hasn’t seen many changes over the last 70 years, heating, ventilation and air conditioning have undergone a revolution. And remaining abreast of those changes – or even ahead of them – has enabled R.H. Lapp & Sons to remain on the cutting edge of industrial and commercial HVAC system installation.

Our investment in a Plasma Cutter allowed us to drastically reduce time spent creating duct work. The computer generated cutter not only quickens fabrication time, it also will slice material as tough as 3-inch thick steel.

Another mechanization that enriched R.H. Lapp & Sons’ reputation as a leader in the industry was our purchase of a TDC Machine, which essentially enables the company to create airtight joints in all duct work.

That means savings in terms of energy usage by clients, and in wear and tear on heating and air conditioning units.

The systems created and installed by R.H. Lapp & Sons range from hot water and forced air to VAV Systems, or Variable Air Volume Systems. Done with either hot water or forced air, VAV Systems allows each individual office or room in a commercial or industrial building to have its own temperature control.

We also insulate all systems we install, including plumbing and HVAC.

That’s invaluable experience put to work for each client served, experience many other mechanical contractors find hard to match.
