Heating Installation in Rockford, IL | Gilley's Heating Experts

The best heating system for your Rockford home depends on existing infrastructure, fuel availability, budget, and comfort priorities. Choose gas furnaces if you have existing ductwork and natural gas service, want lowest operating costs, and need reliable heat for extended -10°F periods (budget $4,000-$7,500). Choose heat pumps if you want one system for heating and cooling, prioritize efficiency, or lack natural gas service (budget $6,000-$10,000). Choose boilers if you have existing radiators, suffer from allergies aggravated by forced air, or can't install ductwork (budget $5,000-$11,000). We'll assess your specific situation and recommend the best option.

Complete heating installation in Rockford typically costs $4,000-$8,500 depending on system type and complexity.

Yes, heating installation in Rockford requires a building permit to ensure code compliance and safety.

This protects you by ensuring your new system meets all local codes, maintains your homeowner's insurance coverage, and doesn't create issues when selling your home.

For Rockford's harsh winters with extended below-freezing temperatures, we recommend high-efficiency gas furnaces (95-96% AFUE) with two-stage or modulating burners for reliable powerful heat and excellent efficiency. Modern cold-climate heat pumps also work well down to 0°F when paired with backup heat. About 70% of Rockford homeowners choose gas furnaces for the best balance of upfront cost, operating efficiency, and reliable performance in Northern Illinois winters.

Schedule professional maintenance annually before heating season (typically September-October). Annual tune-ups catch small issues before they become expensive breakdowns, maintain peak efficiency to keep operating costs low, extend equipment lifespan by 3-5 years, and keep manufacturer warranties valid. Many warranties require proof of annual professional maintenance. We offer Comfort Club memberships that include priority scheduling, discounts, and automatic maintenance reminders.

Yes, we have several excellent options for homes without existing ductwork. Ductless mini-split systems provide efficient heating and cooling without ducts, perfect for additions or older homes. Boilers with radiators or radiant floor heating work beautifully in homes with existing hydronic systems or where ductwork installation is impractical. We can also install new ductwork if that's your preference, though it adds 2-4 days and $3,000-$8,000 to the project depending on home size and layout.
