Heating & Boilers

Commercial Heating and Boiler Repair in Dallas

Gas heat gets little attention in a city that runs cooling most of the year, until the first cold snap exposes a pilot that will not hold or a heat exchanger with a crack in it. We repair gas-fired boilers and hot-water heating loops for buildings that need reliable heat on the handful of days DFW actually demands it.

  • Same-day and next-day service calls
  • Chiller plants up to 500 tons
  • All major brands
Commercial gas boiler and hot-water piping in a mechanical room

What's covered

Boiler ignition and pilot repair

Servicing pilot assemblies, ignitors, and flame sensors that keep a boiler from lighting or from staying lit.

Heat exchanger inspection

Checking for cracks and corrosion that can allow combustion gases to enter the airstream, a safety issue as much as a comfort one.

Hot-water loop diagnostics

Tracing circulation problems, air-bound piping, and pump faults that leave parts of a building cold while others overheat.

Combustion and flue analysis

Testing combustion efficiency and flue draft to confirm the boiler is burning gas cleanly and venting properly.

Control and aquastat repair

Fixing failed aquastats and boiler controls that mis-fire the heating cycle or run the loop at the wrong temperature.

Common symptoms

Facilities usually call about one or more of the following before a tech is ever dispatched.

  • Pilot light will not stay lit after multiple relight attempts
  • Boiler short cycles on and off within a few minutes
  • Some zones of the building run cold while others overheat
  • Popping or rumbling noise from the boiler during a heating cycle
  • Soot or discoloration visible around the flue connection
  • Circulator pump running but radiators or unit heaters stay cool

How the visit works

  1. 1
    Safety check first

    Before any repair, we check for gas leaks, flue draft problems, and heat exchanger integrity, since heating equipment carries combustion risk.

  2. 2
    Ignition and control diagnostics

    We test the pilot, ignitor, flame sensor, and aquastat to find what is preventing a clean, sustained heating cycle.

  3. 3
    Loop-side troubleshooting

    Circulator pumps, zone valves, and piping are checked when the boiler fires correctly but heat is not reaching all zones.

  4. 4
    Combustion verification

    A combustion analyzer confirms the burner is operating within safe and efficient parameters before the call is closed.

Equipment we service

Our techs carry diagnostic tools for equipment across manufacturers rather than specializing in one brand. Equipment we service includes:

Common questions

Is it dangerous if my boiler's pilot keeps going out?

It can indicate a flame sensor, thermocouple, or draft problem, and repeated relighting without diagnosing the cause is not something we recommend.

Why is one part of my building cold while the rest is fine?

That pattern usually points to a zone valve, circulator pump, or air-bound section of the hot-water loop rather than the boiler itself.

Do you check for carbon monoxide risk during a heating repair?

Yes, heat exchanger and flue inspection are part of every boiler service call, since a cracked exchanger is a safety issue first.

How often does commercial heating equipment need attention in Dallas?

Less often than in colder climates, but that also means problems get discovered late. A pre-season check before the first cold snap catches most of them early.

Tell us about the equipment and the symptom, and we will get a technician scheduled.
