Why Fall Preparation is Critical

The first heating system failure often occurs on the coldest night of the year. Fall preparation ensures reliable operation when you need it most.

DIY Safety Checks

Visually inspect your furnace for rust, cracks, or soot. Check the pilot light (if applicable) and ensure the area around the furnace is clear of flammables.

Professional Inspection Benefits

A certified technician checks heat exchanger integrity, calibrates gas pressure, tests safety controls, and ensures carbon monoxide detectors are working.

Thermostat Preparation

Switch from cooling to heating mode. Program seasonal schedules, replace batteries, and consider upgrading to a learning thermostat if you have an older model.

Efficiency Improvements

Fall is a good time for insulation upgrades, duct sealing, and window treatments that reduce heating demands and lower bills.

Frequently Asked Questions

Quick answers to common questions

Signs include a sulfur smell, soot around the furnace, visible cracks, or a yellow/flickering pilot light. Only a professional can confirm with proper testing.

Schedule service in September or early October before HVAC companies get busy with emergency calls.
