Trusted Boiler Repair Services

Complete Boiler Services for Dallas Homes

While most North Texas homes rely on forced-air furnaces, thousands of older properties in neighborhoods like the M Streets, Lakewood, and Preston Hollow still depend on hydronic heating and these systems demand a specialist, not a general technician. Boilers involve pressurized water, gas connections, and venting requirements that differ entirely from standard HVAC equipment, so inexperienced repairs often create safety risks or shorten system life. Our Team provides complete care under one roof: diagnostics, repair, annual maintenance, and professional boiler installation for radiator, baseboard, and radiant floor systems, ensuring your home heats evenly, safely, and efficiently every winter.

Boiler Repair Near You

When a boiler acts up, the warning signs rarely fix themselves: strange banging or kettling noises, radiators that stay cold at the bottom, dropping pressure, leaking valves, or a pilot light that won’t hold. Ignoring these symptoms usually leads to bigger failures and costlier repairs, and in some cases, dangerous carbon monoxide exposure. Being based right here in Dallas, our technicians reach you quickly, diagnose the actual fault instead of guessing, and explain your options before any work begins. Whether it’s a faulty circulator pump, thermocouple, expansion tank, or zone valve, we repair it right the first time.

Boiler Installation & Gas Boiler Replacement

If your boiler is past the 15-year mark, needs frequent repairs, or struggles to heat your home evenly, replacement often makes better financial sense than another fix. Older units typically operate at 60–70% efficiency, while modern condensing models reach 90% or higher, a difference you’ll notice on every winter gas bill. Castle AC Heating & Cooling handles the entire process: assessing your home’s heating load, recommending the right size and type, and completing your boiler installation to code with proper venting and safety testing. Our gas boiler replacement service includes removal of the old unit, upgraded controls, and full parts and labor warranties.

Annual Boiler Maintenance

A yearly tune-up is the single most effective way to protect your boiler’s lifespan and your family’s safety. During each visit, our technicians perform a full combustion analysis to verify the burner is firing cleanly, inspect the heat exchanger for cracks or corrosion, test safety controls and pressure relief valves, and check for gas leaks or carbon monoxide risks. We also bleed radiators, verify system pressure, and clean components that gradually collect scale and sediment. Beyond safety, regular upkeep restores lost efficiency, prevents mid-winter breakdowns, and keeps manufacturer warranties valid- small annual attention that saves significant money over the system’s life.

Frequently Asked Questions

Do You Service Residential Boilers in Dallas?

Yes. Castle AC Heating & Cooling repairs, maintains, and installs residential boilers throughout Dallas and North Texas, including radiator, baseboard, and radiant floor heating systems.

How Much Does Gas Boiler Replacement Cost?

Gas boiler replacement typically ranges from $4,000 to $10,000+ depending on size, efficiency rating, and venting requirements. We provide free quotes with transparent, upfront pricing.

How Often Should a Boiler be Serviced?

Once a year, ideally before winter. Annual boiler service keeps combustion safe, maintains efficiency, prevents breakdowns, and protects your manufacturer warranty coverage.

Why is My Boiler Losing Pressure?

Pressure loss usually points to a water leak, a failing expansion tank, or a faulty pressure relief valve. Our technicians can diagnose and fix it quickly.

Should I Replace My Boiler With a Furnace or Heat Pump?

It depends on your home’s setup. Converting requires ductwork, which adds cost. If you have radiators or radiant floors, a modern boiler installation is often the smarter choice.
