As a Twin City homeowner, you know how the weather can turn on a dime. The best way for homeowners to prepare for below-freezing temperatures is to stay on top of their routine maintenance.

Our trusted and certified-trained technicians are happy to help. Below, we explore common home boiler problems many homeowners face.

Boiler Diagnosis

Boiler diagnoses vary with the type of appliance, age, and usage, but there are a few repairs that consistently crop up over the life of Minnesota boiler systems. Before winter gets the best of you, keep these prospective boiler repairs on your radar—and keep McQuillan Bros on your speed dial.

3 Symptoms of Boiler Trouble

Boiler Leaks 

One of the most common issues for steam and hot water boiler owners is leaking. Leaks generally spring from a few different places: broken seals or valves, poorly soldered fittings, or corroded tanks. Remedies may include resealing the boiler pump, replacing a valve, removing tank debris, or replacing the entire unit.

Boiler’s Lime Scale

 Mineral buildup restricts water flow, causes boiler pressure valves to malfunction, decreases efficiency, and leads to “kettling.” (As lime deposits restrict water flow, your boiler may sound like a kettle rattling on the stove.) In some cases, limescale inflicts severe damage on your boiler’s interior, so routine flushing and descaling are essential. You may also need to install a water treatment system to protect the integrity of your boiler for seasons to come.

Boiler Has a Cold Radiator

Our friends at Gilmore Heating, Air, and Plumbing, an HVAC company in Placerville, agree that even when your boiler is heating water properly, trapped air, a faulty pump, or a bad thermostat may cause radiators to malfunctioning. If your radiator isn’t heating, don’t troubleshoot the problem on your own. Call a professional trained in the safe handling of steam and hot water boiler repair in Ramsey County. DIY boiler repairs could lead to scalding, gas exposure, or water damage.

Broken Boiler Noises

Be On Guard for These Broken Boiler Noises

In our last blog, we covered a few common boiler troubles that plague Minnesota residents during winter months. While some familiar heater problems are sneaky and silent, others alert you with annoying and worrisome noises. Take this clanking, popping and banging seriously! If your heater sounds like a whining kettle or mimics the neighbor’s amateur garage band, it’s time to call in the best HVAC company in Ramsey County.
Steam and hot water boilers may “sound off” as they age when limescale builds in the tank or air gets trapped in the heating system. While a noisy boiler isn’t always unsafe, a faulty appliance could be hazardous. Approaching every repair with your safety in mind, McQuillan Bros’ certified technicians handle loud boiler systems with care to prevent scalding or electrical risk.

Sounds You Shouldn’t Hear From a Healthy Boiler

  1. Rumbling & clanking due to limescale. Known as “kettling,” knocking or clunking noises usually occur when a mineral coating builds inside the boiler’s heat exchanger. Excess sediment blocks water flow and leads to water expansion, steam buildup and rapid boiling. The result: a loud sound similar to a kettle that’s boiling over on the stovetop. Your steam or hot water boiler contains a pressure relief valve designed to minimize the dangers of kettling, but, over time, limescale causes internal damage and takes a toll on efficiency.
  2. Rumbling & clanking due to thermostat setting. When your thermostat is set too high, it can also lead to rapid boiling inside the water heater tank. Reduce the thermostat setting to eliminate this type of kettling noise. In some cases, your thermostat may be defective and should be changed out by a boiler repair technician.
  3. Gurgling or whistling. These sounds may occur when pipes or traps are frozen or air has accumulated in your boiler or radiator system. A boiler repair professional can thaw frozen pipes or bleed the radiator system to release trapped air and restore normal water flow. If you decide to bleed the system yourself, proceed with caution. Hot water is purged during the process and could lead to scalding.
