No overtime fees. That's our policy, and it doesn't change.

Boiler work is different from standard HVAC repair. A boiler is both a heating appliance and a pressurized plumbing system, which is why most HVAC techs aren't equipped to touch one properly. Our technicians carry dual certification in both plumbing and HVAC, which means they diagnose the full system, not just the burner. Common boiler repairs include circulator pump failure, pressure relief valve replacement, zone valve issues, expansion tank problems, and gas valve faults. What drives repair cost up or down is mostly system age, parts availability for older models, and whether the heat exchanger is still sound. A cracked heat exchanger is the line between a repair call and a conversation about boiler installation. We'll tell you honestly which side of that line you're on. Every job is different, contact Brick Street Plumbing Heat & Air for an accurate estimate.

Common Problems

Boiler Symptoms Worth Calling About

Most boiler failures give warnings before they quit completely. Here's what to watch.

No Heat or Weak Output

If radiators or baseboards stay cold, the problem could be a failed circulator pump, a stuck zone valve, or a thermostat that lost communication with the boiler. Don't assume it's the burner. Most no-heat calls in Loudoun County turn out to be a pump or valve issue.

Banging or Kettling Noise

Loudoun County's water is hard, and mineral deposits build up inside the heat exchanger over time. That rumbling or banging sound is steam forming in restricted passages. It shortens boiler life fast. We flush and descale as part of the repair visit when this is the cause.

Pressure Dropping or Spiking

A boiler that keeps losing pressure usually has a failing expansion tank or a small leak in the system. High pressure readings point to a faulty pressure relief valve. Both conditions need attention before they become dangerous, not just inconvenient.

Boiler Leaking Water

Leaks come from several places: the pressure relief valve (it's doing its job, but something upstream is wrong), corroded pipe fittings, or a crack in the heat exchanger itself. Location matters. We find the source before recommending a fix, not after.

Pilot Light or Ignition Failure

Older boilers with standing pilots fail more often in cold snaps. Newer electronic ignition systems can fail too, usually from a faulty igniter or a dirty flame sensor. This is a repair, not a replacement. Unless the burner assembly is damaged or the part is no longer manufactured.

Boiler Cycling On and Off

Short cycling wastes fuel and puts extra wear on components. It usually points to a bad thermostat, a blocked flue, or a faulty aquastat. We check all three before concluding anything. A boiler that short-cycles for months ends up needing a much bigger repair.

How We Diagnose and Repair Your Boiler

Three steps from your call to a working heating system.

Full System Diagnostic
We check pressure, temperature, burner operation, zone valves, circulator pumps, and the expansion tank before touching anything. Guessing at a boiler repair is how you end up paying twice.
Honest Assessment
We tell you what the repair costs and whether it makes sense given the boiler's age and condition. If a replacement pencils out better over five years, we say so. We're not going to sell you a repair that buys six months on a system that's done.
Repair and Verification
We complete the repair, restore system pressure, cycle the boiler through a full heating sequence, and check for any secondary issues before we leave. The heat should work that night.

Repair vs. Replacement: Knowing the Difference

The honest answer is: it depends on age, condition, and repair cost relative to replacement cost. A boiler under 15 years old with a functioning heat exchanger is almost always worth repairing. One that's 25 years old, showing corrosion at the heat exchanger, and needing its second major repair in three years is probably not. Leesburg has a lot of older homes, particularly in and around the historic district, and many of them still run on original cast iron boilers from the 1970s and 1980s. Those systems can run for decades more with proper maintenance, or they can fail catastrophically if ignored. We've seen both. Our dual-certified technicians can assess cast iron sections, test heat exchanger integrity, and evaluate flue draft in ways a general HVAC tech simply isn't trained for. If replacement is the right call, we'll walk you through your options for a new boiler installation at the same visit. No second appointment needed.

Why Dual Certification Matters for Boiler Repair

Most heating companies are either plumbers or HVAC contractors. Boilers straddle both trades. The burner and controls are HVAC. The distribution system, zone valves, expansion tanks, and circulator pumps are plumbing. When a single-trade tech shows up, they see half the system. We hold both licenses, which means one call covers the whole system. If your furnace repair tech couldn't fix a boiler issue on a previous visit, that's probably why. It's not a knock on them. It's a scope of license issue. Brick Street carries both. We also won't recommend a water softener installation on every boiler call, but for homes in Loudoun County with well water or older supply lines, the mineral scale problem is real and worth addressing before it kills another heat exchanger.

Your Questions

Boiler Repair Questions We Hear Often

How often should a boiler be serviced or inspected?

Once a year, before heating season. For Leesburg, that means a September or early October visit. A proper inspection covers the burner, heat exchanger integrity, flue draft, zone valves, expansion tank pre-charge, and circulator pump operation.

What are the signs my boiler needs repair instead of replacement?

Age and heat exchanger condition are the two factors that matter most. A boiler under 15 years old with a sound heat exchanger almost always makes more sense to repair. If the system is over 20 years old, showing visible corrosion on the sections, and needs a second significant repair, replacement is usually the better investment. We'll tell you which situation you're in after the diagnostic, not before.

Why is my boiler making a banging or rumbling noise?

Loudoun County water runs hard, typically above 10 grains per gallon in many parts of the county. That hardness deposits calcium and lime scale inside the heat exchanger over time. When scale builds up in restricted passages, water can flash to steam before it exits, causing the banging or kettling sound you're hearing. We descale the heat exchanger during the repair. Ignoring it accelerates heat exchanger failure significantly.

What's the difference between a boiler and a furnace?

A furnace heats air and distributes it through ductwork. A boiler heats water and distributes it through pipes to radiators, baseboard heaters, or radiant floor systems. Boilers generally provide more even, comfortable heat because radiant warmth doesn't dry out the air the way forced air does. They also require different maintenance and a different skill set, specifically, plumbing credentials in addition to HVAC certification.

Can you repair older boiler models, including cast iron systems?

Yes. Historic Leesburg properties frequently have cast iron sectional boilers installed decades ago. Parts availability varies by manufacturer and age, but cast iron systems that have been properly maintained can run well past 40 years. We assess section integrity before recommending repair or replacement. If a section is cracked, that's a heat exchanger failure and it changes the math on repair cost significantly.

Why is my boiler losing pressure and how do I fix it?

Pressure loss almost always points to one of three things: a waterlogged or failed expansion tank, a small leak somewhere in the distribution piping, or a pressure relief valve that's discharging when it shouldn't. All three are repairable. Don't keep re-pressurizing the system through the fill valve without finding the cause. That approach masks the problem and can accelerate corrosion in the distribution lines.
