Preparing Your Goodman Furnace for Summer

Putting your Goodman furnace into hibernation for the summer isn't just about flipping a switch. Proper shutdown helps extend its lifespan and prevents costly repairs down the line. This guide will walk you through the process safely and effectively. Remember, always consult your Goodman furnace manual for specific instructions related to your model.

Step 1: Turn Off the Power

Before starting any maintenance, safety is paramount. The first step is to switch off the power supply to your furnace. Locate the breaker switch in your electrical panel and turn it to the "off" position. This prevents accidental electrocution during the shutdown process.

Step 2: Inspect and Clean the Furnace

Take this opportunity to perform a thorough inspection and cleaning of your furnace. A clean furnace operates more efficiently and lasts longer.

Check the filter: Replace or clean your air filter. A clogged filter restricts airflow, reducing efficiency and potentially damaging the system.
Clean the burners and heat exchanger: Use a soft brush or vacuum to remove dust and debris. If you're uncomfortable doing this yourself, call a qualified HVAC technician.
Inspect the pilot light (if applicable): Ensure the pilot light is in good working order. If it's flickering or weak, it might indicate a problem needing professional attention.

Step 3: Turn Off the Gas Supply (If Applicable)

If your Goodman furnace runs on natural gas, locate the gas valve. This is usually a shutoff valve near the furnace. Turn the valve clockwise to the "off" position. Double-check that the gas is completely off.

Step 4: Check for Leaks

After turning off the gas, use a soapy water solution to check for gas leaks around the gas line connections. Bubbles forming indicate a leak, requiring immediate attention from a qualified gas professional. Never attempt to repair gas leaks yourself.

Maintaining Your Goodman Furnace During Summer

While your furnace is off, don't forget about preventative maintenance:

Schedule a Professional Inspection: Consider scheduling an annual professional inspection for your Goodman furnace. A technician can identify and address potential issues before they become major problems.
Check for Pests: Rodents and other pests can cause significant damage to your furnace. Regularly inspect the area surrounding the unit and take appropriate measures to deter pests.

When to Call a Professional

While many shutdown procedures are DIY-friendly, some situations demand professional help:

Gas Leaks: Never attempt to fix gas leaks yourself. Call a qualified gas professional immediately.
Unusual Noises or Odors: If your furnace makes unusual noises or emits strange odors, it's best to call for professional service.
Age of the Furnace: Older furnaces may require more specialized attention during the shutdown and startup processes. It's always safer to consult a professional.

Preparing for Next Winter: Restarting Your Goodman Furnace

When autumn arrives, remember to reverse these steps. Before turning the power and gas back on, ensure the filter is clean and the unit is clear of obstructions.

By following these steps, you'll ensure your Goodman furnace is properly prepared for the off-season, extending its life and ensuring reliable heating when you need it most. Remember, safety should always be your top priority. If you have any doubts or uncertainties, always contact a qualified HVAC professional.
