Local project guide

What to know before you start.

As a homeowner in Northbrook, you understand the demands of Chicagoland weather on your home’s systems. With the village's family-oriented neighborhoods, from the stately homes in The Estates to the well-established ranches of Founders Pointe, many properties share a common thread: an aging housing stock. After 55 years, or even less for hard-working units, an older furnace or air conditioner starts losing its step, impacting comfort and running up energy bills. That's where Lake & Oak Co. steps in. We expertly project-manage your HVAC replacement, ensuring a seamless upgrade to a more efficient, reliable system tailored to your Northbrook home. We connect you with vetted, license-verified trade specialists, providing a single point of contact for a significant home improvement.

What Your HVAC Upgrade Project Entails

When you choose Lake & Oak Co. for your HVAC replacement, you’re investing in a comprehensive, headache-free process. Our project management approach means you get transparency and professional coordination from start to finish. Here’s what you can expect as part of your system upgrade:

  • Existing Equipment Removal: Safe and clean disposal of your old furnace, air conditioner, or both.
  • New System Installation: Professional setup of your new, high-efficiency furnace and/or AC unit, ensuring optimal performance.
  • Permit Handling: Complete coordination and filing for all necessary gas and village permits with Northbrook authorities, so you don’t have to worry about the paperwork.
  • System Integrity Checks: Thorough inspection of existing refrigerant lines and ductwork to ensure compatibility and efficiency with your new equipment.
  • Efficiency Assessment & Rebates: A comprehensive energy-efficiency assessment and assistance with all applicable rebate paperwork to help you save.
  • Full System Commissioning: Detailed testing and balancing of your new system, followed by a personal walkthrough to ensure you understand its operation and maintenance.

Investment for Northbrook Homeowners

An HVAC replacement is a significant investment in your Northbrook home's comfort and value. For most projects in the area, homeowners can expect a price range of $6,000 to $14,000. Northbrook’s median home value, around $545,000, reflects a standard of quality that extends to home systems. Given the median home age of 55 years, many properties – from classic colonials to comfortable townhomes – are excellent candidates for an HVAC upgrade. Older homes might require more extensive ductwork inspections or modifications for optimal modern system performance, which can influence the upper end of this range. We focus on providing solutions that make sense for your specific property, balancing efficiency, budget, and long-term reliability.

Northbrook Project Spotlight: Mission Hills Townhome HVAC Refresh

A recent project brought us to a charming townhome in Northbrook's Mission Hills neighborhood. The owner, Ms. Chen, reached out because her existing air conditioner was struggling to keep pace during summer, and her furnace was making concerning noises. After our initial assessment, it was clear both units, original to the 40-year-old property, were past their prime.

Our vetted HVAC trade partner recommended a high-efficiency central air conditioner and a matching natural gas furnace, sized perfectly for the townhome’s square footage and layout. We coordinated all the necessary village permits and the gas permit with North Shore Gas. The specialists carefully removed the old, inefficient units, taking care to protect Ms. Chen's landscaping and interior. Installation of the new systems went smoothly over two days, including thorough inspections of the existing ductwork and refrigerant lines. Ms. Chen now enjoys consistent temperatures, noticeably lower energy bills, and peace of mind knowing her new system is designed to perform reliably for years to come.

What Our Northbrook Clients Are Saying

— Sarah M., The Estates, Northbrook

"Living in Founders Pointe, we appreciate good service. We needed our aging AC replaced before summer hit. Lake & Oak Co. connected us with great specialists who did fantastic work. The entire process, from getting the Northbrook permits to the final walkthrough, was well-managed. Our new AC keeps our ranch home perfectly cool."

— David R., Founders Pointe, Northbrook
