Cahill Heating, Air Conditioning & Electric

Service is always efficient. If what is needed is a repair, the explanations given about what options are clear and honest. They do not overcharge or take advantage to suggest unnecessary actions.

It is clear why they have been in bus8ness so long. They foster lifelong relationships with their customers by providing great service. I CANNOT RECOMMEND CAHILL ENOUGH! FANTASTIC!

Josh was amazing! Great service for our annual time up, thanks guys!

Just moved to Lake Bluff and needed new Furnace & AC. Lots of options but I chose Cahill. I'm so glad I did. Incredible customer service, professional service people and best-in-class quality. I've since had them install a water heater and most recently, they came to fix the pilot light on my gas fireplace. I highly recommend Cahill. They're amazing!

I was in a tight spot over the holiday weekend and Cahill came out and took care of what needed done. Mark and the crew had me up and running in a very timely manner. They patched my 17 year old hvac unit to get me through the weekend and then that following Monday they were able to order, pick up and on Tuesday morning install two brand new units on my roof! By 12 noon the job was cleaned up and complete! Cahill Electric and Heating are responsive, efficient and professional 5 stars all the way.

Josh was professional, knowledgeable, and trustworthy! Highly recommend!

I have used Cahill heating and air conditioning and electric for 40 years. They are the best on the North Shore. Don't call anyone else but CAHILLL thank you . Jim Turk

Excellent service and communication throughout the process of diagnosing and replacing our air conditioning units. Each contact was professional and knowledgeable: Joe, Mark, Ken and our Installation Specialist Hayko -- We have worked with Cahill over the past 20+ years and will continue to call them whenever needed.

Hard working, good service, knowledgeable. Everything you want. Highly recommend.

Yesterday, Matt was our service technician from Cahill, here for an annual maintenance check of the HVAC ductless system. He checked and cleaned all room unit parts, spray washed the outdoor unit to clear the condenser fins of all debris blocking the air flow, then climbed into the hot attic to check pump and drain lines for leaks & flush any blockage. Excellent service!

Cahill has installed & serviced our heating and cooling units 2012. They are knowledgeable, courteous, punctual, honest and reasonable with charges. We highly recommend them.

Ask for Brandon. He’ll really service your unit thoroughly.
