A furnace replacement is a significant investment, and mistakes can be costly. Here are the most common furnace replacement mistakes homeowners make and how to avoid them.
1. Choosing Based on Price Alone. The cheapest quote often means inferior equipment or rushed installation. Get multiple quotes and compare scope. For typical costs, see furnace replacement cost.
2. Not Checking Licensing and Insurance. Hiring an unlicensed contractor leaves you liable. Always verify credentials—see how to choose a licensed contractor.
3. Ignoring Sizing. An oversized or undersized furnace causes comfort and efficiency problems. A proper load calculation is essential. See what to expect during replacement.
4. Skipping Permits. Unpermitted work can void insurance and complicate resale. Ensure permits are pulled—see permits and codes.
5. Neglecting Ductwork. Old, leaky ducts can undermine a new furnace’s efficiency. Ask your contractor to inspect and seal ductwork during replacement.
6. Not Checking the Warranty. Understand what is covered by the manufacturer’s warranty and the contractor’s workmanship warranty.
