As a commercial HVAC project Manager, O'Leary exceeded my already high expectations in quality, responsiveness and value. They were out here the same day as my call after normal work hours, and had my new furnace installed 48 hours after the initial call. The craftsmanship of the install is commercial-quality, and they were responsive to my specific requests on connection points. The pricing was exceptionally fair and transparent. The owner Vince is former union sheetmetal and treats his customers and employees like a neighbor and not like a private equity HVAC company. I'm reccomending O'Leary to friends and family for residential HVAC work. Thank you!

VM O'Leary is great. They have been very responsive to our calls for assistance.....we highly recommend them. Today, Daniel answered our last-minute call and was very helpful in diagnosing the problem.

Professional thorough kind reliable listen to my concerns excellent service above and beyond what I even expected. I would never use anyone else ever. And his wife is the sweetest woman ever when I've called because I get nervous about something or I have any questions they're always very kind and patient and explain things over the phone just a wonderful company and again very kind thorough exceptional service through and through the whole ordeal my nephew used Vince's company also to do a whole heating system in his home in Crystal Lake that's actually a landmark! Because I recommended him and told them don't even look for anybody else!

I had called before Easter to make a appointment for a cleaning of the furnace and ac check. Judy was going to check with Vince on when a Saturday would be available,still waiting. I believe in giving my money to local business but looks like I'll have to call someone else out of my area.

Family owned business. Responds quickly to any needs that arise at any time of day.

HVAC system maintenance

I use V.M. Oleary for many years they always went out of their way to do an excellent job. I would and have highly recommended them.

Very nice a/c installation a year ago, it's been running great. Got good maintenance tips from installer as well.

Great people to work with.

Vince came out and went over our needs and explained everything in detail. They came and installed everything and went over operating the system and new thermostat . Vince’s wife is so wonderful- when talking to her she is so caring and helpful.

I have used oleary sheet metal for many of my remodel jobs.their prices are fair, they show up when scheduled, and the employees do great work and are respectful of the customers property.

Responsive and professional. Easy to work with. Got back to us quickly.

The Team at VM O'Leary is great to work with. I would highly recommend their team. I have had them to a furnace replacement as well as some repair work. They are responsive, show up on time. I feel they are reasonably priced and provide good recommendations for repairs when new needed. Thanks!

Absolutely the best - great service, professional, reasonable, and always the best quality.

VM O’Leary was on time and did a great job. Clean neat and very fair

Great service & knowledgeable on their products, used for forced air and boiler work!

Very reliable prompt and they actually fixed the problem rather than selling a whole new system. Patient and thorough Highly recommend

Quality installation at a fair price. Vince is very knowlegable and he stands behind their work. Great techs. Highly recommend.
