‘Can’t Say Enough Good Things’

V. M. O’Leary is very competent in both residential and commercial settings. As a professional in the construction industry, I have referred him to building owners, some with several buildings who now use V. M. O’Leary Heating exclusively.

I have also referred him to a good personal friend who had some work done on their house.

Vince and I have collaborated on the HVAC design for a commercial project in Crystal Lake – he is very capable working from the design end as well as the installation side of the business.

Can’t say enough good things about him, and I have heard great feedback from those I have referred him to – which makes us look good.

Knowledgeable, Friendly Service

When it is decided by a family to spend thousands of dollars for a home upgrade, you can bet, considering the economy, that much thought and planning are going to go into the decision.

Finally determining we wanted to go green and save some money, we called numerous contractors to give us a bid for a new high efficiency furnace and A/C unit.

V.M. O’Leary was one of the contractors we called, and right from the beginning it was very obvious what kind of person we were dealing with. Vince O’Leary was knowledgeable, articulate and explained what needed to be done in a language even I could understand. We never felt pressured, and all of our questions were answered logically and with great detail, leaving nothing left to be mistaken.

We would recommend V.M. O’Leary heating with a great deal of confidence. How fortunate for us we choose them to do our work.
