Boilers & Hydronics

Reliable Boiler & Hydronic Heating Solutions for the Eastern Sierra

Are you waking up to ice-cold floors, hearing loud kettling sounds from the baseboards, or finding a puddle forming under the boiler? These are serious mechanical failures that will not resolve by simply bleeding the radiators or bumping up the thermostat. MCR Services Inc. is ready to diagnose your system and restore your heat today.

MCR Services Inc. knows exactly how high-altitude Eastern Sierra climates stress these complex heating systems. We show up equipped to trace pressure drops, ignition failures, and zone valve lockouts so you can get your home's radiant heat back online.

Boiler Repair & Service

When a boiler starts acting up, it rarely fixes itself. We get calls every day for kettling, a total lack of hot water, sudden pressure loss, or boilers flashing cryptic lockout codes. Mechanically, these symptoms usually point to a failed circulator pump, a water-logged expansion tank, a faulty aquastat, or altitude-related combustion issues. Our diagnostic process starts with the fundamentals to isolate exactly where the failure occurred.

We check the pressure relief valves, test the zone valves for proper operation, and analyze the combustion to ensure the fuel is burning cleanly in the thin mountain air. The reality of boiler repair is that catching a problem early saves you from a massive headache down the road. Replacing a weeping pressure relief valve or a failing sensor is a straightforward fix. Letting it go until the system runs dry and cracks the heat exchanger is a multi-thousand dollar disaster.

If a system is too far gone to repair economically, customers often pivot to Boiler Installation & Replacement instead. However, our priority is always to restore your current equipment if it is safe and cost-effective to do so. We carry the right parts and the right diagnostic tools to get your system firing again.

Common culprits we check during a service call:

• Failed or seized circulator pumps
• Water-logged expansion tanks losing pressure
• Faulty aquastats or temperature sensors
• Altitude-related combustion and drafting issues
• Weeping pressure relief valves
• Blocked or air-locked zone valves

Whether you need a quick fix or a major mechanical overhaul, our Boiler Repair & Service team handles every call across the Eastern Sierra.

Boiler Installation & Replacement

There comes a point where nursing an old system just doesn't make financial sense. The warning signs of a dying boiler include constant unrepairable leaks at the cast iron sections, soaring energy bills because the efficiency has tanked, or heavy rust scaling on the heat exchanger. You might also find that replacement parts for your specific unit are no longer manufactured. When we look at replacement, we never just swap boxes and walk away.

We calculate the specific heat load for high-elevation homes, evaluate venting requirements for altitude-sensitive combustion, and install high-efficiency, modulating systems. As factory-trained installers for Lochinvar and Raypak, we make sure the new boiler is piped properly to match your home's flow requirements. The trade-off is blunt: continuing to dump money into a thirty-year-old, inefficient boiler costs you far more in wasted fuel and emergency service calls than investing in a modern system.

A modern boiler actually heats the house evenly while dramatically cutting your fuel consumption. Pair every new install with annual Boiler Maintenance to protect the manufacturer warranty and catch normal wear early. We take the time to design a system that will survive the harsh winters and keep your property protected from freezing temperatures.

Signs You Need a Replacement

- Constant leaks around the cast iron sections - Soaring energy bills due to tanking efficiency - Obsolete parts that are no longer manufactured - Heavy rust scaling on the primary heat exchanger - Frequent lockouts requiring constant resets

Boiler Maintenance

Most boiler emergencies we respond to could have been prevented with basic maintenance. The symptoms of a neglected boiler are subtle at first, like sluggish heating, uneven room temperatures, or the system running constantly without ever satisfying the thermostat. Over time, glycol breaks down and turns acidic, expansion tanks lose their air charge, and burners get fouled by dust and debris. If you ignore these subtle signs, the system will eventually lock out when you need it most.

Our maintenance process is incredibly thorough and designed specifically for mountain properties. We test the water quality and glycol levels to ensure your system has proper freeze protection for severe winter conditions. We also clean the burners, verify all safety limits, check the ignitor, and bleed trapped air from the system. Paying for routine maintenance lets us catch a weak component in the middle of the afternoon, rather than you losing heat entirely in the dead of the night.

If we find a failing component during the inspection, a Boiler Repair & Service visit is the logical next step to prevent a breakdown. Catching a seized pump or a clogged pressure valve during a routine check is always cheaper than paying for emergency service. We highly recommend scheduling this service before the first deep freeze hits the region.

What our maintenance process includes:

• Testing water quality and active glycol levels
• Cleaning the burners and inspecting the heat exchanger
• Verifying all safety limits and pressure controls
• Checking the ignitor and flame sensor
• Bleeding trapped air from the system loops
• Inspecting the expansion tank air charge

Hydronic Heating Systems

Hydronic systems provide incredible comfort, but when they act up, they require specialized troubleshooting. Customers usually call us when they notice distinct cold spots on their radiant floors, baseboards that refuse to get hot, or constant rushing and gurgling noises in the pipes. These issues are almost always caused by air locked in the loops, seized circulator pumps, failed zone actuators, or sludged-up manifolds that restrict flow.

To fix it, we do not just bleed the system and walk away. We purge the lines entirely, balance the manifolds so every zone gets the right amount of flow, and replace any actuators that are failing to open. Ignoring a gurgling loop isn't just annoying, it means your circulator pump is working twice as hard to push water through trapped air, and it will eventually burn out. Proper flow is the absolute key to making radiant heat work the way it was designed.

If your hydronic loop is tied to a failing heat source, we might recommend Boiler Installation & Replacement to resolve the root cause. Otherwise, we focus on the distribution side of the system, ensuring the hot water actually makes it to the rooms that need it. We carry the specialized equipment required to flush, purge, and balance complex radiant setups.

Common Hydronic Failures We Fix

- Air locked inside the radiant loops - Seized or burned-out circulator pumps - Failed zone actuators and sticking valves - Sludged-up manifolds restricting water flow - Thermostats failing to trigger the zone relays

Comprehensive Climate Control for the Eastern Sierra

Boilers and hydronic systems are the heart of many mountain homes, but they often intersect with other vital climate control systems. If your boiler is emitting unusual odors or you suspect a venting issue, our Gas Leak Detection service ensures your home's fuel lines are safe and secure. We take combustion safety incredibly seriously, especially in tightly sealed winter cabins.

For homes that utilize a mix of radiant heat and forced air, we also provide comprehensive Heating Repair to keep your entire property comfortable. If you are looking to supplement your boiler's heating capabilities with zoned climate control, our Heat Pump Repair teams can maintain and optimize your hybrid setup. Having one reliable contractor who understands both the water and air sides of your HVAC system saves you time and frustration.
