For all of your residential, commercial and recreational generator needs, Jacobazzi Heating & Cooling has the experience and knowledge to match your specific requirements to the most efficient and highest quality product.  We are your comprehensive provider of new and used purchases, maintenance, parts and accessories.  Our licensed technicians will be happy to provide information and make practical recommendations.

Power outages are disruptive to everyday life. Suddenly, you’re left without amenities such as the washer, dryer, microwave and coffeemaker. In Downers Grove, IL and the surrounding areas, going without electricity for any length of time can also be dangerous and damaging. When the outside temperature drops into the negatives and the snow piles up in feet, you need a functioning heating system. For the summer heat and humidity, air conditioning makes a big difference.

From protecting against frozen pipes, spoiled perishables and flooded basements to comfort, better sleep and convenience, a standby generator keeps essential equipment operational. The furnace, air conditioner, water heater, sump pump, lights, refrigerator and targeted appliances or the entire home can continue to operate as normal.

We’re Here to Answer Your Generator Questions

Professional installation of standby generators is a requirement to ensure reliability, safety and warranty coverage. Jacobazzi Heating & Cooling is well-versed in the leading industry options and happy to accommodate your specific needs. Along with incorporating a generator that automatically starts up and fulfills demands whenever needed, our skilled technicians provide ongoing maintenance and repairs. We achieve peace of mind.

While there is a wide spectrum of available choices, Jacobazzi Heating & Cooling can help narrow those options to find the perfect fit.  We offer generators that are fuel efficient, provide long run times and deliver consistent power, avoiding fluctuations that can cause equipment to shut down or damage appliances.  If sound levels are an issue, most generators are labeled with decibel ratings.

Portable generators provide quiet power for camping, RVing, tailgating and much more.  There’s no installation needed, and we offer lightweight, compact models to facilitate moving and storing your generator.

Home standby generators permanently backup your power system.  Installed directly into your home’s wiring, an automatic transfer switch provides a convenient and reliable backup power supply that will take over the moment you experience an outage.

Industrial use generators are designed with construction work in mind, supplying durable, consistent and long-lasting power.  For commercial use, an efficient generator will keep your business up and running during a blackout.

Your Choice for Generators, Jacobazzi Heating & Cooling

Noise levels, fuel efficiency & run time, power output quality, portability, ease of starting, durability and quality of craftsmanship are important factors to consider before making an investment in a new generator.  With an extensive selection, we guarantee to solve your needs.  Our expert technicians will provide any new installation or necessary maintenance to old or used generators.  Contact Jacobazzi Heating & Cooling for both portable and standby generators.

What Our Customers Are Saying
Paul M.

“Fantastic service with professionalism. This company not only handles our current maintenance needs, but our recent purchase of a new A/C unit displayed to us how a company completes the task far better than expected. The work area was properly cleaned and the new unit was better than expected. We will always call Jacobazzi for all our A/C and Heating needs for our work needs, and future recommendations to family and guests.”

“I’ve been a Jacobazzi customer since 2014. They are always kind, professional and happy in their work. They live and work locally, making them a great part of the community. They are available to help at all hours but have always fit me in quickly during normal hours, which is awesome as problems only seem to happen during peak weather.”
