How do I know what type of heating system is best for my home?

The best system depends on your existing infrastructure, fuel availability, and budget. Homes with ductwork and gas service typically benefit from gas furnaces ($4,000-$7,500). Homes with radiators should consider boilers ($5,000-$11,000). Energy-conscious homeowners wanting heating and cooling might choose heat pumps ($6,000-$10,000). We assess your home and recommend the best option during free consultation.

Do I need a permit to install a heating system in Rockford?

Yes. All heating system installations in Rockford and Winnebago County require building permits. Gilley's handles all permit applications, ensures code compliance, coordinates final inspections, and obtains certificates of completion. Permit fees are included in our installation quotes.

What type of heating is best for Rockford's climate?

Gas furnaces are most popular in Rockford for reliable powerful heat during -10°F winters at lower operating costs. High-efficiency models (95-98% AFUE) provide best performance. Modern cold-climate heat pumps also work well down to 0°F. We recommend systems based on your home's specific needs during free assessment.

How often should I service my new heating system?

New heating systems should be professionally serviced once per year, ideally in September or October before Rockford's heating season. Annual maintenance costs $140-$185 but prevents 75-80% of breakdowns, extends system lifespan 5-7 years, and maintains efficiency.

Can you install heating in a home without ductwork?

Yes. We install ductless mini-split heat pumps (no ducts required), boiler systems with radiators or radiant floors, or design and install complete duct systems for homes adding forced-air heating. We assess your home and recommend the most cost-effective solution.
