When it comes to your furnace and keeping your home cozy, there’s no shortage of advice out there. Friends, family, and even the internet often share tips about heating maintenance – but not all of that advice is true. In fact, some common beliefs about furnace tune-ups are pure myths that can actually put your family’s comfort and safety at risk.

At Absolute Comfort Heating & Air Conditioning, we believe in setting the record straight. In this friendly myth-busting guide, we’ll debunk the top furnace tune-up myths so you can keep your home safe, warm, and running efficiently.

Myth #1: “If it’s not broken, you don’t need to fix it.”

The Myth: Many homeowners assume that as long as the furnace seems to be running fine, a tune-up isn’t necessary.

The Reality: Even if your furnace appears to be working, hidden issues can develop inside the system that lead to inefficiency, higher energy bills, or even carbon monoxide leaks. A routine furnace tune-up is essential for catching these problems early and ensuring your system is safe and optimized for performance. During a tune-up, well-trained HVAC technicians check critical components like burners, filters, blower motors, and most importantly, the heat exchanger.

The heat exchanger plays a vital role in separating combustion gases from your indoor air. If a cracked heat exchanger goes unnoticed, it could leak carbon monoxide into your living space, posing serious health risks. That’s why all professional maintenance should include a thorough heat exchanger inspection by certified technicians.

Myth #2: “Furnace tune-ups are a waste of money.”

The Myth: Some homeowners skip tune-ups, thinking they’re unnecessary unless there’s a breakdown.

The Reality: Preventative maintenance helps avoid costly repairs, extends the life of your furnace, and improves energy efficiency. A tune-up also includes inspections that protect indoor air quality and keep your family safe from issues like heat exchanger cracks or improper ventilation. Professional heat exchanger diagnostics are key to maintaining a safe, well-functioning heating system.

Myth #3: “All HVAC technicians are the same.”

The Myth: Homeowners may assume that every technician has the same training and standards.

The Reality: At Absolute Comfort Heating & Air Conditioning, we set ourselves apart by undergoing advanced training and certification. Our team is one of the only in Weber and Davis County, Utah, to earn credentials from Heat Exchanger Experts, the industry-leading authority in heat exchanger inspection training.

Myth #4: “Carbon monoxide detectors are enough to keep my home safe.”

The Myth: Having CO detectors installed means you don’t need to worry about what’s going on inside your furnace.

The Reality: CO detectors are important, but they only alert you after there’s a problem. The better approach is prevention. A qualified technician trained in heat exchanger diagnostics can detect potential failures before they become dangerous. Regular tune-ups, especially those that include a comprehensive heat exchanger inspection, help ensure your system is not leaking harmful gases.

Myth #5: “Newer furnaces don’t need heat exchanger inspections.”

The Myth: A newer furnace doesn’t need much attention, right?

The Reality: Newer systems can still develop issues, especially if they weren’t installed properly or have airflow restrictions. Cracks can form in a heat exchanger due to overheating, corrosion, or manufacturing flaws. That’s why even new systems benefit from regular furnace tune-ups that include a heat exchanger safety check.
