About this service

What to expect from our duct repair team

### El Costo Oculto de los Ductos con Fugas en Hogares de LA El Departamento de Energía estima que los sistemas de ductos residenciales típicos pierden entre el 20 y 30% del aire acondicionado a través de fugas antes de que llegue a los espacios habitables. En Los Angeles, donde el aire acondicionado trabaja intensamente de mayo a octubre, eso significa que está pagando por enfriar su ático en lugar de su sala cada verano. La reparación de ductos es una de las mejoras de HVAC con mayor retorno de inversión que un propietario en Los Angeles puede realizar — y aborda directamente la causa más común de quejas de confort (temperaturas desiguales, habitaciones que siempre están demasiado calientes o demasiado frías).

Descripción General

  • ### Señales de que Sus Ductos Necesitan Reparación La mayoría de los propietarios no tienen idea de que sus ductos tienen fugas porque estas están ocultas en áticos, espacios de acceso y cavidades en las paredes. Identificamos problemas de ductos mediante una combinación de mediciones de flujo de aire (comparando lo que el equipo produce con lo que cada habitación recibe), pruebas de presurización de ductos e inspección visual de secciones de ductos accesibles. Daños comunes que encontramos: secciones de ductos desconectadas en juntas y derivaciones, revestimientos internos de ductos flexibles desgarrados, ductos flexibles aplastados por el tráfico peatonal en el acceso al ático, mastique deteriorado en plenums de suministro, y juntas con cinta deteriorada en ductos de lámina metálica más antiguos.
  • ### Métodos de Reparación Los métodos de reparación de ductos dependen del tipo de daño y del material del ducto. Las secciones de ductos flexibles desconectadas se reconectan y sellan con mastique y cinta de aluminio. Los revestimientos internos desgarrados requieren reemplazo de sección. Las juntas de lámina metálica se sellan con mastique. Para sistemas con pequeñas fugas generalizadas en todo el sistema de distribución, el sellado de ductos Aeroseal (un proceso de sellado presurizado interno) puede abordar fugas que no son accesibles para reparación manual.
  • ### Documentación Antes y Después Documentamos la fuga de ductos antes y después de la reparación usando pruebas de duct blaster — una prueba de presurización que cuantifica la fuga total de ductos como porcentaje del flujo de aire del sistema. Esto le proporciona evidencia medible de que el trabajo mejoró el rendimiento de su sistema.

Our Service Benefits

Ahorro de energía medible
Sellar fugas de ductos del 20–30% puede reducir el consumo de energía del HVAC entre un 15 y 25% — un retorno de inversión que generalmente se mide en meses, no en años.
Mejor confort de inmediato
Las habitaciones que siempre eran incómodas reciben el flujo de aire para el que fueron diseñadas. La mejora en el confort generalmente se nota desde el primer día.
Pruebas antes/después
Cuantificamos la fuga de ductos antes y después de la reparación con pruebas de duct blaster — evidencia medible de la mejora.
Reduce el desgaste del equipo
Los ductos con fugas hacen que el equipo de HVAC funcione por más tiempo para alcanzar la temperatura programada. Los ductos sellados reducen el tiempo de funcionamiento y extienden la vida útil del equipo.

FAQ

Common questions about duct repair in Los Angeles

¿Cómo sé si mis ductos tienen fugas?
El síntoma más claro son habitaciones que consistentemente son más difíciles de calentar o enfriar, combinado con facturas de energía altas. Los registros de suministro polvorientos pueden indicar fugas en ductos de retorno que aspiran aire no acondicionado del ático. Una prueba profesional de presurización de ductos (prueba de duct blaster) cuantifica exactamente cuánta fuga existe en su sistema.
¿Cuánto cuesta la reparación de ductos en Los Angeles?
Reparaciones específicas en secciones desconectadas o daños evidentes: $200–$600 dependiendo de la ubicación y accesibilidad. Sellado integral de ductos en un sistema con fugas generalizadas: $800–$2,000. Sellado interno de ductos Aeroseal para fugas de difícil acceso: $1,500–$3,000 para un hogar típico. Proporcionamos un presupuesto por escrito después del diagnóstico.
¿Puedo reparar los ductos yo mismo?
Las reconexiones de ductos flexibles accesibles son posibles como proyecto de bricolaje usando cinta de aluminio y mastique adecuados. Sin embargo, la mayor parte de las fugas significativas de ductos ocurren en juntas, plenums y derivaciones en espacios de ático que son difíciles de acceder e inspeccionar sin experiencia. Las reparaciones incorrectas pueden empeorar las cosas. El diagnóstico y la reparación profesional garantizan que los problemas correctos se solucionen adecuadamente.
¿Qué es el sellado de ductos Aeroseal?
Aeroseal es un proceso patentado que sella los ductos desde el interior. El sistema presuriza la red de ductos e inyecta una niebla de partículas de polímero adhesivo que se adhieren y sellan las fugas a medida que el aire fluye a través de ellas. Es particularmente efectivo para fugas en secciones inaccesibles de ductos. Ofrecemos Aeroseal para sistemas donde la reparación manual no puede alcanzar todas las fugas.
¿Cuánto tiempo toma la reparación de ductos?
Reparaciones específicas en daños accesibles: 2–4 horas. Sellado manual integral de un sistema de ductos completo: un día completo. Sellado Aeroseal: típicamente 4–6 horas para el proceso de sellado más el tiempo de configuración y pruebas.
¿La reparación de ductos ayudará a que mi sistema de HVAC dure más?
Sí. Los ductos con fugas obligan a su equipo de HVAC a funcionar en ciclos más largos para alcanzar la temperatura programada. Más tiempo de funcionamiento significa más desgaste en el compresor, motor del ventilador y intercambiador de calor. Los ductos sellados reducen el tiempo de funcionamiento, disminuyen el ciclo de trabajo del equipo y extienden la vida útil de los componentes.
¿Necesito permisos para la reparación de ductos?
Las reparaciones menores de ductos (sellar fugas existentes, reconectar secciones) generalmente no requieren permisos. La instalación de ductos nuevos o un rediseño significativo de ductos sí requiere permisos. Asesoramos sobre los requisitos de permisos según el alcance específico del trabajo.
¿Las fugas en los ductos pueden causar problemas de calidad del aire?
Sí. Las fugas en los ductos de retorno en el ático aspiran aire no acondicionado del ático — cargado de fibras de aislamiento, polvo y posibles esporas de moho — hacia la corriente de aire acondicionado. Las fugas en los ductos de suministro en el ático introducen aire del ático directamente en los espacios habitables a través de corrientes inversas en los registros. Sellar las fugas de los ductos puede mejorar significativamente la calidad del aire interior, no solo el confort y la eficiencia.

Our furnace wasn't heating evenly upstairs. LC found that half of our ductwork in the attic had separated and was blowing hot air into the attic. Repaired everything and now every room heats equally. Professional and transparent.

LC did a full duct inspection and found we were losing 35% of our conditioned air through disconnected joints in the attic. After sealing and repairing, the difference was immediate — better airflow, lower bills, no more hot spots.

Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.
