Boiler Services
Boiler systems provide reliable, comfortable hydronic heating for homes and commercial buildings throughout Nashville. Harpeth Air offers expert boiler repair, maintenance, and installation services with technicians experienced in all boiler types and configurations.
Boiler Repair
Boilers are among the most reliable heating methods, but they require specialized knowledge for proper repair. Common problems include circulator pump failures, expansion tank issues, zone valve malfunctions, pressure relief valve problems, and control system failures. Ignition problems, gas valve issues, and control board failures require boiler-specific knowledge because safety control sequences differ from furnaces. We diagnose and repair all boiler types including gas, oil, and electric boilers in both residential and commercial applications.
Boiler Installation
Installing a new boiler requires expertise in hydronic system design, plumbing, gas fitting, venting, and electrical work. Boiler sizing follows different calculations than forced-air systems, considering heat loss for each zone, water flow rates, and modulation range. We install residential boilers from single-zone systems to complex multi-zone homes with radiant floor heating, hydronic towel warmers, and indirect water heaters. Modern condensing boilers achieve 95 percent or higher efficiency.
Boiler Maintenance
Annual boiler maintenance is essential for safe, efficient operation. Our service includes combustion analysis, water chemistry testing, circulator pump inspection, expansion tank check, safety control verification, and thorough cleaning of the heat exchanger and burner assembly. Proper water chemistry management is critical for boiler longevity, preventing corrosion and scale buildup that reduce efficiency and shorten equipment life.
Frequently Asked Questions
How long do boilers last?
Well-maintained boilers typically last 20 to 30 years, significantly longer than forced-air furnaces. Cast iron boilers can last even longer. Regular maintenance including water chemistry management is key.
Are boilers more efficient than furnaces?
Modern condensing boilers achieve 95 percent or higher efficiency, comparable to the best gas furnaces. Hydronic heating distributes heat more evenly and eliminates duct losses that reduce effective furnace efficiency.
Why is my boiler leaking water?
Common causes include failed pressure relief valves, corroded piping connections, expansion tank problems, or circulator pump seal failures. Any boiler leak should be addressed promptly to prevent water damage.
