Furnace Installation FAQs
Common questions about furnace installation in Chicago.
How much does furnace installation cost in Chicago?
Furnace installation in Chicago typically ranges from $2,800 to $8,500 depending on the efficiency rating, size, and complexity of the installation. High-efficiency 96%+ AFUE systems cost more upfront but significantly reduce monthly heating bills. D's Air provides free estimates with upfront pricing before any work begins.
How long does furnace installation take?
Most residential furnace installations are completed in one day — typically 4 to 6 hours. Multi-unit or commercial installations may take 1–3 days depending on the number of units.
What size furnace do I need for my Chicago home?
Furnace sizing is determined by a Manual J load calculation based on your home's square footage, insulation, windows, and layout. An oversized furnace short-cycles and wears out faster. An undersized furnace runs constantly and can't keep up on the coldest days. D's Air performs proper load calculations on every installation.
What is AFUE and why does it matter?
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts gas to heat. An 80% AFUE furnace wastes 20 cents of every dollar spent on gas. A 96% AFUE furnace wastes only 4 cents. In Chicago's cold winters, upgrading from 80% to 96% AFUE can save hundreds of dollars per year on heating bills.
Do you require a service contract for furnace installation?
No. D's Air does not require service contracts or maintenance agreements. You pay only for the work you need — no hidden fees, no recurring charges unless you choose them.
Proper Sizing Is Everything
Every furnace installation starts with a proper Manual J load calculation to ensure the right size system for your home. An oversized furnace short-cycles, wastes energy, and wears out faster. We size it right the first time, install it clean, and test it thoroughly before we leave.
