Frequently asked questions
How do I know if my furnace needs a repair or a full replacement?
We test and document the actual issue before recommending anything. Many furnace problems come down to a single failed component, not the whole unit. If replacement genuinely is the better value, we’ll show you why, backed by real readings, not just the system’s age.
What does a diagnostic visit cost?
A flat $69 — a thorough inspection with a clear, documented diagnosis before any work begins.
Is a 20-year-old furnace automatically due for replacement?
System age alone is not a diagnosis. Many systems can continue to operate reliably with proper maintenance and targeted repairs, even beyond typical industry averages.
