We called for an emergency replacement of our furnace that stopped working and they not only beat every estimate we got they were out there within the hour to do the job. I can't say enough about what a great experience I had with this company.
When I purchased a new office for my business in St Charles I bid out my heating and a/c installation. McNally's was extremely competitive and provided superior value to any of the other companies I'd spoken with. The business owner was very responsive (and I did call at some odd hours initially) and I just thoroughly enjoyed having them do the install. Since then I've referred them to several people including my family and they have done other installs for an extremely competitive price and with great service. I'm very happy with them overall and highly recommend.
