A lot of housing stock in Mound was built in the 1960s, 70s, and 80s. That means you're more likely to encounter systems with older ductwork configurations, furnaces that have been retrofitted more than once, or setups where the previous owner made decisions that weren't exactly by the book. We've seen all of it. The diagnostic step isn't a formality for us. It's how we figure out what's actually going on before we quote anything. If you're on a tight budget and want to know whether a repair makes financial sense versus replacement, that's a conversation we're genuinely willing to have. We're not going to push you toward a number that doesn't work for your situation.
