What You Can Do Yourself

Filter Replacement

This is the easiest DIY task. Turn off your system, locate your filter, note the size, and replace it with a matching high-efficiency filter. Most filters are located in a return air duct or blower compartment.

Vent Cleaning

Walk through your home and visually inspect all vents and registers. Use a vacuum with a brush attachment to remove dust and debris. This improves airflow and heating efficiency.

Thermostat Check

Test your thermostat by setting it to heating mode and a temperature higher than the current room temperature. You should hear the system kick on within a minute.

While some maintenance tasks are simple, several require professional expertise and equipment:

  • •Heat exchanger inspection: A cracked heat exchanger can be dangerous
  • •Gas connection checks: Ensuring safety requires professional inspection
  • •Refrigerant checks: Only certified technicians can handle refrigerant
