American Weathermakers is the most trusted choice for HVAC services in Northfield, Illinois

Northfield homeowners rely on American Weathermakers for all of their HVAC services. American Weathermakers has been a local business in the North suburban community for many years. Our customers have time and again trusted us to maintain their air conditioning and heating needs since 1949. American Weathermakers enjoys providing a service to our friends and neighbors in Northfield so they have the best heating and cooling care possible.

With nearly 5,420 people residing in Northfield, we’ve been the go-to HVAC provider for many homeowners for decades. We are well known for air conditioning and heating repairs and our customers trust us for our advanced service for several other HVAC-related repairs and products, including:

Home Comfort Checkups - Our most recommended service to our Northfield home owners is our Home Comfort Checkup.

Air Quality Control - Northfield residents can always expect to get the best advice and products for air filter replacements, upgrades and repairs and humidity control.

Sump Pump Maintenance - There is a high potential for floods in homes that have basements. Since many Northfield homes have basements, flooding is a frequent hazard. American Weathermakers will install or improve your existing sump pump system to guard your home from water damage. 

Water Heaters - A typical Northfield family will use 2,000 gallons of hot water each month on average - if your water heater isn’t working correctly, it can be a source of a lot of money wasted and aggravation.

Boiler Services - American Weathermakers offers the products and services you require for all boiler system needs to keep you and your family warm and comfortable during cold winter months.

Home Zoning Systems - American Weathermakers can split your home’s ductwork system into detailed zones so you can heat or cool rooms at specific times. This service will save you money and will prevent energy loss.

Insulation Services - If your home is older than a decade, it might not be as insulated as you think it is. Insufficient insulation can result in lost temperature-controlled air and higher energy costs.

If any part of your HVAC system needs service, trust us to send a professional HVAC technician to your Northfield home that can address all of your concerns and give you the most reliable advice about what will work well for you and your home. Call us at (847) 509-7777 or contact us here to get service to your home in Northfield today!
