At J.C.'s Heating & Air, we understand that homeowners have many questions about furnace installation and replacement. Below, we've compiled some of the most frequently asked questions to help you make informed decisions.
Most furnaces last 12 to 15 years, depending on the brand, usage, and maintenance. If your unit is approaching that age—or if it requires frequent or costly repairs—it may be time to consider a replacement.
The correct furnace size depends on your home's square footage, insulation, ceiling height, window efficiency, and layout. Our team performs a Manual J load calculation to recommend a properly sized system that will keep your home comfortable and efficient.
Replacing your furnace proactively—before a complete failure—can help you avoid winter breakdowns and ensure you get the best efficiency and rebate options. Waiting until it fails can lead to rushed decisions and emergency pricing during peak demand.
