For Chicago, reliable mid-range brands include Carrier, Trane, and Lennox ($10400–$13300). Budget-friendly Goodman and Rheem ($7500–$9900) offer excellent value. Focus on SEER2 rating and installer reputation over brand prestige.
Do I need a permit for HVAC replacement in Chicago?
Yes — Chicago requires a mechanical permit for HVAC replacement, including like-for-like equipment swaps. Permits typically cost $75–$200 and require a post-installation inspection. A licensed IL HVAC contractor will pull the permit as part of the job. Never accept an offer to skip permits — it voids your homeowners insurance claim and can cause problems when selling your home.
Should I repair or replace my HVAC system in Chicago?
The rule of thumb: if repair cost exceeds 50% of replacement cost ($5800 in Chicago), replace it. Also consider age: if your AC is 15+ years old or furnace 20+ years old, replacement makes more financial sense. New 16 SEER2 systems typically save $200–$600/year in energy vs. a 10-year-old system — often paying back in 5–8 years.
Are heat pumps worth it in Chicago?
Potentially — modern cold-climate heat pumps work down to -13°F. In Chicago, a heat pump with a gas furnace backup (dual fuel) is often the most efficient combo. The federal $2,000 tax credit applies.
