Wahl Blog: Pittsburgh HVAC and Plumbing Advice

Why we made Bosch our exclusive cold-climate heat pump

A Pittsburgh HVAC owner explains why Bosch became his exclusive cold-climate heat pump: pressure transducer tech, simple wiring, quiet, compact, and reliable.

Doing the right thing when it costs us money

Three true stories from a Pittsburgh master plumber on standing behind the work, the gas line, the Halo 5 leak, and the dead tankless I sent out at 5 pm.

What I wish every Pittsburgh homeowner knew before calling any contractor

A Pittsburgh master plumber on why this trade is closer to the wild west than you think, and how to vet a contractor with Google reviews and the BBB first.

The Pittsburgh permit and inspection truth nobody tells you

A licensed Pittsburgh mechanical contractor on Allegheny County code, city permits that can take months, and what inspectors actually check on an install.

The Pittsburgh air quality problem nobody talks about: summer humidity

Pittsburgh summers get humid and your AC may not remove enough moisture. A master plumber on sensible vs latent heat and the whole-home dehumidifier fix.

What is actually in Pittsburgh water (and what is hype)

A Pittsburgh master plumber on what is really in your tap water, chloramine, dissolved solids, heavy metals, hardness, and the exact setup he runs in his own home.

Why bigger is not better: the oversized furnace problem

A Pittsburgh master plumber explains why an oversized furnace burns up the heat exchanger and short cycles, and what to do if you want more heat instead.

The heat pump backup-heat mistake we catch on other companies’ installs

An undersized heat pump and bad backup-heat programming costs Pittsburgh homeowners comfort. A master plumber explains the fixes and a cheap freeze backup.

The $55,000 system that pays my customer $600 a month

A Pittsburgh master plumber on why he quoted $55,000 when others quoted $12,000, and how the system cut a $1,200 electric bill in half.

80% vs 96% furnace: when I actually tell you to save your money

When does an 80% furnace make sense over a 96% high-efficiency unit? A Pittsburgh master plumber gives the honest answer on venting, cold spaces, and condos.
