The Heating & Air Company Seattle Recommends
Boiler heating systems provide exceptional comfort and efficiency through radiant heat, baseboard systems, or in-floor heating—but they require specialized expertise for proper service and maintenance. Fischer Heating & Cooling has served Seattle-area homes with hydronic heating systems since 1977, delivering expert boiler repairs, comprehensive maintenance, and professional installations that homeowners trust. Our boiler specialists understand the unique requirements of hot water and steam heating systems, providing quality service on all boiler makes and models.
Whether your home features a traditional cast iron boiler, a modern high-efficiency condensing unit, or a combination boiler providing both heat and domestic hot water, our experienced technicians deliver the specialized service these sophisticated systems require. From annual maintenance that ensures safe, efficient operation to emergency repairs that restore heat when you need it most, Fischer Heating & Cooling is the boiler service expert Seattle homeowners have relied on for nearly five decades.
Circulator pump failures, air in the system, zone valve problems, or thermostat issues can prevent proper heat distribution throughout your home. Our diagnostic expertise identifies and resolves these issues quickly.
Water leaks around your boiler may indicate pressure relief valve problems, deteriorating gaskets, corroded heat exchangers, or piping connection failures. We pinpoint leak sources and provide lasting repairs.
Kettling, banging, gurgling, or whistling sounds indicate problems like sediment buildup, air in the lines, pressure issues, or circulator problems that need professional attention.
Pilot lights that won’t stay lit, burn yellow instead of blue, or require frequent relighting indicate thermocouple failures, gas pressure issues, or venting problems.
Boilers that frequently lose pressure may have hidden leaks, expansion tank failures, or fill valve problems that our technicians diagnose and repair.
Cold spots, noise, or leaks in your heating distribution system require specialized knowledge to repair properly.
Our boiler repair service begins with thorough system diagnostics using specialized boiler testing equipment. We inspect the entire hydronic heating system—not just the boiler itself—to identify the root cause of problems. Common repairs include circulator pump replacement, zone valve repairs, pressure relief valve service, expansion tank replacement, gas valve and control repairs, heat exchanger leak repairs, and thermostat troubleshooting. We work on all boiler fuel types including natural gas, propane, oil, and electric, and service all major brands.
Regular boiler maintenance is critical for safe, efficient operation and long equipment life. Our comprehensive tune-up service includes complete combustion analysis and adjustment, heat exchanger inspection and cleaning, burner cleaning and optimization, circulator pump inspection and lubrication, expansion tank testing and service, pressure relief valve testing, system pressure verification, water treatment evaluation, zone valve and control testing, radiator and baseboard inspection, complete safety inspection, and detailed performance report. Annual maintenance prevents 90% of boiler breakdowns while improving efficiency and extending system life.
When it’s time to replace your aging boiler, Fischer Heating & Cooling provides expert installation of high-efficiency boiler systems. Our installation services include proper sizing for your home’s heating needs, selection from leading manufacturers, complete removal of your old boiler, professional installation to code, system flushing and chemical treatment, zone controls and thermostat integration, thorough testing and commissioning, and complete system operation training.
Boiler emergencies require immediate professional attention. Our 24/7 emergency service provides rapid response for no-heat situations, water leaks and flooding, gas odors or safety concerns, and strange noises or pressure problems. Our emergency technicians carry specialized boiler parts and have the expertise to restore heat quickly and safely.
Beyond the boiler itself, we service all components of your hydronic heating system including circulator pumps, zone valves and controls, expansion tanks, air eliminators, fill valves and backflow preventers, radiators and baseboard heaters, in-floor heating manifolds and controls, and thermostats and control systems.
