Furnace repair scenarios explained: What you need to know

Both furnaces and heat pumps are designed to keep your home warm, but they function in fundamentally different ways. Furnaces use combustion to create heat, typically utilizing natural gas or propane. Heat pumps, on the other hand, work by transferring heat from one area to another—either from outside your home to the inside or vice versa. If your furnace is showing signs of malfunction, read about the common furnace repair scenarios to get you a better understanding of what to expect.

1. Heat exchanger replacement

The heat exchanger is the heart of your furnace, responsible for transferring heat to warm up your home. A cracked or damaged heat exchanger can result in poor heating and even pose a risk of carbon monoxide leakage.


Typical repair process:

1. Diagnosis: Inspect for cracks, rust, or other damages.

2. Removal: If faulty, old heat exchanger will be carefully removed.

3. Installation: A new heat exchanger will be installed and tested for proper function.


What to expect:

Cost: This can be a high-cost repair, often ranging from $1,275 to $5,500.

Time: A heat exchanger replacement typically takes about 4-6 hours.

2. Gas burner replacement

The gas burner is where fuel and air mix to produce the flame that heats your home. A malfunctioning gas burner can result in an inefficient furnace.


Typical repair process:

Integrity, Transparency & Honesty: The cornerstones of a reputable Furnace repair servic

Before you commit to a service provider, ensure that their practices are aligned with these three pillars. Below are the questions you should be asking.

Transparency starts with a clear, written estimate that outlines labor costs, parts, and other fees. At Comfort One, we provide detailed and written estimates that leave no room for hidden charges. Before any of our furnace repairs are started, we discuss the estimate with you and wait for your approval.

3. What Kind of Parts Do You Use?
