The deep cold is always coming sooner than we think, and there is nothing worse than a heating failure when temperatures drop. As your trusted HVAC experts, we know that preparation is the best defense against a mid-season emergency. That’s why we’ve put together this essential pre-season checklist, focusing on simple steps you can take today to ensure your boiler heating system or furnace is ready to handle the winter months ahead efficiently and reliably.
The Winter HVAC Check: A Pre-Season Checklist for Furnaces and Boilers
The Essential Filter and Vent Check
The first and simplest step in winter HVAC maintenance is checking your air filter. A clogged filter restricts airflow, forcing your unit to work harder and waste energy. We recommend inspecting it monthly and replacing it if it is dirty to maintain efficiency and indoor air quality. Additionally, ensure all heating vents are open and not blocked by furniture or rugs, allowing warm air to circulate freely throughout your home.
Understanding Pilot Lights and Ignition Systems
For units with pilot lights, ensuring they are lit and burning a steady blue flame is a crucial part of furnace and boiler maintenance. A yellow or sputtering flame often indicates a gas flow issue or a problem with the thermocouple. If your unit has an electronic ignition, test it a few times early in the season to confirm it lights reliably. These checks prevent small issues from becoming larger, expensive problems later on.
Examining Radiators and Baseboard Heaters
If your home relies on a boiler heating system, we advise checking radiators for cold spots, which could signal air trapped inside. Bleeding the radiators releases this air and improves heating performance. For baseboard heaters, wipe away any dust or debris, which can impede heat transfer and pose a mild fire hazard. This simple care, combined with proactive professional service, maximizes your system's output.
When to Schedule a Professional Tune-Up
While simple tasks are great, nothing replaces the thorough inspection of a certified technician. We urge homeowners to schedule their annual service before winter to prevent unexpected breakdowns and costly furnace repair. During this service, we clean internal components, check electrical connections, and calibrate the system.
