Historic Pittsburgh Homes Demand Master Hydronic Specialists

Whether you live in a stately stone Tudor in Mt. Lebanon, a Victorian in Shadyside, or a brick colonial in Squirrel Hill, your boiler is the lifeblood of your winter comfort.

Many modern HVAC companies treat boilers like standard furnaces and lack the craft of steam pressure regulation, near-boiler header piping, or radiator balancing. Our master hydronic technicians understand the physics of steam and hot water, preserving your historic radiators while upgrading efficiency.

  • Cast-iron steam boiler sizing & pressuretrol calibration
  • Elimination of clanking, banging radiators ('water hammer')
  • Near-boiler black iron pipe header replacement
  • Multi-zone hydronic valve control for even heat on every floor

TECHNOLOGY COMPARISON

Types of Boilers We Service & Install

Every home has a unique hydronic setup. Here is how steam, hot water, and combi systems compare.

Steam Boilers

HISTORIC HOMES

Common in classic Pittsburgh brick homes with large cast-iron radiators. Operates at low pressure (0.5–2 PSI) to deliver powerful radiant heat without blowing dry air.

  • Single-pipe & two-pipe steam systems
  • Sight glass & low-water cutoff safety
  • Pressuretrol regulation & radiator venting
  • Weil-McLain PEG & Williamson steam models

Hot Water Hydronic Boilers

RELIABLE & QUIET

Uses closed-loop circulator pumps to push hot water through radiators, baseboards, or radiant floor tubing. Whisper-quiet, consistent heat with precise multi-zone control.

  • Zone-valve controlled multizone heating
  • Baseboard radiators & cast-iron radiators
  • Expansion tank & air purger management
  • Cast-iron longevity: 20–30+ years

Mod-Con Combi Boilers

ULTRA-EFFICIENCY

Modulating-Condensing technology that heats your home AND provides endless on-demand domestic hot water from one compact wall-hung unit. Frees up basement space.

  • Up to 96% AFUE gas efficiency
  • Replaces bulky water heaters + boilers
  • PVC direct-vent through sidewall
  • Navien, Lochinvar & Bosch certified
UPGRADE GUIDE

High-Efficiency Mod-Con vs. Cast-Iron Boiler

When replacing your boiler, should you stick with a heavy cast-iron system or upgrade to a 95%+ AFUE condensing unit? Here is how to decide.

GET A CUSTOM ASSESSMENT
01

Traditional Cast-Iron (82–85% AFUE)

  • Extremely durable — last 25 to 35+ years
  • Lower upfront equipment and installation cost
  • Vents through existing masonry chimney (chimney liner required)
  • Ideal for high-temperature cast-iron steam systems
  • Simpler mechanical components with fewer electronics
02

Mod-Con Condensing (95–96% AFUE)

  • Cuts winter natural gas bills by 20% to 35%
  • Modulates flame down to match exact outdoor temperatures
  • Wall-hung compact design frees up basement floor space
  • Direct-vents through PVC piping (no chimney needed)
  • Qualifies for up to $1,000+ in gas utility rebates

FAQ

Boiler Questions Answered

Do you repair both steam and hot water boilers in Pittsburgh?
Yes. Many homes in Mt. Lebanon, Squirrel Hill, and Shadyside rely on steam or hot water radiators. Our technicians are specialized master hydronics experts trained on single and two-pipe steam systems, pressuretrol regulation, and modern high-efficiency condensing boilers.
How much does a new boiler cost to install in Pittsburgh?
A standard cast-iron replacement ranges from $6,500 to $9,500. High-efficiency modulating-condensing (Mod-Con) boilers or combi boilers range from $8,500 to $14,000+. High-efficiency units qualify for rebates through Peoples Gas and Columbia Gas.
Why are my radiators banging or clanking loudly?
In steam systems, 'water hammer' occurs when steam meets standing condensate water in pipes or radiators, often caused by a failed steam vent or improper radiator slope. In hot water systems, it is usually air trapped in the lines or high water velocity. We can balance and bleed your radiators to stop the banging.
What should I do if my boiler is leaking water?
Turn off the electrical emergency switch and shut off the cold water feed line if water is pouring out. Common causes include a tripped pressure relief valve (due to a waterlogged expansion tank), a cracked cast-iron section, or leaking pipe joints. Call us immediately for emergency diagnosis.
How often does a boiler need to be serviced?
Boilers should receive a professional tune-up and safety inspection once a year in the Fall before heating season begins. We test low-water cutoffs, clean heat exchangers, inspect draft hoods, and check for deadly carbon monoxide leaks.
