I have had only good experiences with Cahill for the past 9+ years. They maintain my furnace/ boiler and my A/C systems. They are prompt, professional and, most importantly, honest when it comes to maintaining these systems. All of their techs are friendly and explain everything so it is easy to understand. I highly recommend Cahill without reservation.
Cahill's has been my go to for HVAC needs over the years. Every technician has been professional, kind and patient with all of my questions.

On time, courteous and efficient
Josh was awesome. Got her early, completed the a.c.check, installed a filter and was finished. Good value at only $99 for the a.c. checkup!!
Josh was professional, knowledgeable, and trustworthy! Highly recommend!
We have used Cahill for our business and our home for many, many years. They are a reliable and trustworthy company. Hayko is fabulous, knowledgeable and professional!
Service guys are awesome. Josh was the rep this time. Easy to speak with and answered any questions I had.
Cahill has been helping us for our heating and cooling needs for about 10 years. They continue to surprise me with their quality of work and the dedications of their expert technicians. An amazing company.
We couldn’t recommend Cahill more highly. They were responsive and professional from the very first call, and quickly addressed our needs.
Our household is a 20 year Trane system owner and when the mice wrought havoc within the air conditioner, a quick early morning call to Cahill resulted in a same day service turnaround repair with A+ results. Our Cahill service tech Josh, is skilled in diagnosis and efficient repair - he even had all the needed replacement parts on his truck. We couldn't be more pleased with the outcome and owner satisfaction of our Trane system - the product quality is outstanding . Please have confidence in Cahill. They will promptly address and take care of your situation!
Hayko was our technician and presented as professional, friendly, and easy to communicate with about the work. He was clear about the repairs needed and the process involved. He worked efficiently and within the estimated time, which allowed for reasonable costs of repairs. We have had good luck with Cahill and will continue to request their services for our HVAC needs. Thank you!
Cahill has been taking care of our HVAC for 20 years, and they always are trustworthy, honest, and provide quality service.

Very happy with service and prices.
Highly recommend Cahill Heating and AC. Very responsive and professional. Will definitely use again.
Cahill always does a wonderful job servicing our home in Lake Forest. Reliable, transparent, and fair pricing. Highly recommend.
Within a month of buying our first home in Lake Forest, the house's old AC unit died! As a new homeowner, I did meticulous research and got bids from the majority of local HVAC companies. We decided to go with Cahill and couldn't be happier we did. Ken was extremely responsive and, despite being very busy at the end of spring/early summer, he was able to come inspect our dead unit. I really appreciate that he took the time to see if it would be possible to repair the unit to save us some money, but it was too far gone. Less than 3 days later, we have a brand new AC unit that cost exactly what we were quoted. And they seemed to have cleaned up the areas in which they worked so much that its cleaner now than before they arrived! TL;DR - If you're unsure about which HVAC company to use on the North Shore, you can't go wrong with Cahill. Friendly, cost-effective, professional and friendly. Extremely satisfying HVAC session.
Best in the business!
When we called, Cahill answered. Our family appreciated their punctual nature, attention to detail, and down-to-business attitude
