Why Proper Furnace Installation in Chicago Matters More Than the Brand?
More Than Just a Brand Name
When Chicago homeowners shop for a new furnace, most focus on brand names: Goodman, Amana, Daikin, Carrier, Lennox, Trane. While the brand matters, the truth is this:
Your furnace is only as good as the installation.
A poorly installed premium furnace will fail faster than a properly installed mid-range system. In fact, the U.S. Department of Energy estimates that improper installation can reduce furnace efficiency by up to 30% — costing you money, comfort, and safety.
At Grand Slam Heating & Cooling, we believe installation quality is the #1 factor that determines how long your furnace lasts and how well it performs in the brutal Chicago winters.
1. The Risks of Cheap Installations
- Wrong furnace size for the home.
- Poor ductwork connections.
- Skipped safety checks.
- No permits or code compliance.
- Inexperienced or unlicensed techs.
2. Common Installation Mistakes
Here are the most frequent mistakes we see when re-doing cheap installs:
- Improper Sizing: Oversized units cycle too often, undersized units run constantly — both wear out faster.
- Ductwork Leaks: Poor sealing causes airflow issues and wasted energy.
- Bad Venting: Can lead to carbon monoxide leaks.
- Skipping Permits: Risks fines and voided warranties.
- Ignoring Airflow: Without balancing, some rooms are freezing while others overheat.
3. Why It Matters in Chicago
- Run for long stretches below freezing.
- Handle wind chill drafts in older homes.
- Manage humidity swings.
