Radiant Heating Repair & Installation in Cotati

If the taps still run hot but the house will not warm up, you need an expert to diagnose your boiler system. John Owens Services diagnoses gas boilers and hydronic heating without assuming that every hot-water complaint has the same cause.

For a boiler installation or replacement in Cotati, our estimates describe how the new heat source will connect to the existing floor loops, radiators, or baseboards. We review sizing, controls, venting and the condition of the connected system. If an older unit is repairable, we explain that option alongside boiler replacement rather than deciding on age alone.

Gas Boiler Repair & Installation in Cotati

On every boiler service visit, our goal is the same: the repair and maintain whenever possible and replace only as a last resort. We only recommend a new boiler or radiant heat installation when it is the best option.

  • Inspect and diagnose boiler and radiant heating issues.
  • Provide expert boiler repairs that help a system last.
  • Review and analyze boiler replacement equipment and compatiability.
  • Maintain boiler equipment with ongoing annual service.
  • Plan and provide professional radiant heating and boiler installation.

When to Arrange Boiler or Radiant Heating Service

  • The boiler fails to start, shuts down repeatedly, or displays an operating fault.
  • Only one thermostat zone or part of the home receives heat.
  • New water leaks, pressure loss, or unusual operating noise appear.
  • Heating performance changes after equipment, thermostat, or control work.

Frequently Asked Questions

Do you repair older Munchkin boilers in Cotati?

Tell us the model, symptoms, and any previous repairs when you book. We can assess the equipment and discuss parts availability. If a repair is impractical, the replacement discussion includes the connected heating system rather than just the boiler cabinet.

Why do I have hot tap water but no radiant heat?

The taps and space heating may use separate equipment, or a shared appliance may have different controls for each demand. A thermostat, pump, zone valve or boiler fault can interrupt heating. Identifying the actual system is the first step.

Can you quote a boiler replacement from a photograph?

Photos help establish the model and layout, but a complete installation estimate needs the heating requirements, venting, controls, and connections checked. We explain what still needs to be assessed before recommending equipment.

Which boiler brands can I ask about?

Ask about Rinnai, Navien, Triangle Tube, HTP, NTI, Lochinvar, U.S. Boiler Company/Burnham, Crown, Peerless, and Laars. Tell us the model and serial number. Repair options depend on the equipment’s condition and parts availability; a logo is not a promise that every model or part is available.

Is a gas boiler the same thing as a furnace?

No. A boiler works by heating water for a hydronic distribution system. while a furnace heats air to distribute through ductwork.

How much will a Cotati boiler repair cost?

Once a technician inspects your system, we will be able to give a clear estimate. Cost is made up of several different factors, such as boiler model, ease of access, and the volume of the issue.

Can radiant floor heating systems be repaired without replacing the flooring?

Yes, a radiant floor system can usually be repaired without replacing flooring so long as the issue is not a deep slab leak or has caused extensive damage.

How often should boilers and hydronic radiant heating systems be serviced?

Radiant heat systems and boilers should be serviced annually, just before winter begins to prepare for heavy use throughout the season.

Can a new high-efficiency boiler work with my existing radiant heating system?

Yes, usually high-efficiency boilers work incredibly well with established radiant heating systems.
