Repair or Replace? How to Decide

Frequently Asked Furnace Repair Questions

Is it better to repair or replace my furnace?

In most cases, repairing your furnace is the right choice if the system is under 15 years old and the issue is minor. However, if your furnace is older, inefficient, or experiencing a major component failure, replacement may be the smarter long-term investment — and our Furnace Installation Services ensure proper sizing and installation.

What does furnace service include?

A standard furnace service works much like an HVAC tune-up, including a full inspection of key components, cleaning, airflow testing, and safety diagnostics. This process helps identify concerns, improve performance, and restore efficient heating. Many homeowners pair this with Seasonal Furnace Maintenance for maximum system longevity.

Can my furnace be repaired?

Yes, most furnaces can be repaired quickly and affordably. Common issues like thermostat failures, ignition problems, airflow restrictions, or worn components are often repaired the same day.

What’s the most expensive furnace repair?

The heat exchanger or control board typically results in the highest repair cost. When replacement becomes more cost-effective, we guide you through the process with honest recommendations and high-quality Furnace Installation Services.
