This creates bimodal demand peaks: a critical need for reliable furnace and boiler service from October to April and a strong demand for AC installation and repair from May to September. Homeowners prioritize energy efficiency due to high seasonal utility costs, creating demand for modern, high-SEER AC units and high-AFUE furnaces.

Get answers to common questions about hvac services in Glendale Heights, Illinois.
For a standard efficiency, single-stage system, full replacement costs typically range from $5,500 to $9,500 for an air conditioner and $4,500 to $8,500 for a furnace, depending on unit size and complexity of installation. Illinois state sales tax applies, and prices can be influenced by local factors like the age of your home's ductwork. It's crucial to get multiple itemized estimates from local, licensed contractors, as costs for high-efficiency models or complex retrofits in older Glendale Heights homes will be higher.
The optimal times are during the mild shoulder seasons—spring (March-April) for your AC tune-up and fall (September-October) for your furnace inspection. Scheduling during these periods ensures your system is ready for our extreme Illinois summers and winters, and you'll find greater technician availability and often promotional pricing. Waiting until the first heatwave or cold snap often leads to emergency service fees and long wait times due to high demand.
Yes. All HVAC contractors must be licensed by the State of Illinois (IDPH) and should pull the required local permits from the Glendale Heights Building Department for major installations. For rebates, always check with Nicor Gas for high-efficiency furnace and water heater incentives and ComEd for air conditioner and heat pump rebates. These utility-sponsored programs change annually but can offer significant savings for qualifying high-efficiency equipment.
Prioritize contractors with a strong local presence, verified Illinois state licensing, and positive reviews from Glendale Heights residents. A reputable provider will perform a detailed Manual J load calculation specific to your home's size, insulation, and windows—not just recommend the same size as your old unit. They should also be transparent about pricing, offer warranties on both parts and labor, and be willing to provide references from nearby jobs.
For furnaces over 15 years old, proactive replacement is often wise. A failure during a Glendale Heights winter storm can be dangerous and leave you facing high emergency repair or replacement costs when contractors are busiest. Planning a replacement allows you to research, secure financing if needed, and choose a high-efficiency model that will improve comfort and lower gas bills. It also prevents the risk of a cracked heat exchanger, which is a serious safety hazard.
