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.
The furnace at my rental property stopped working and my tenant had called 4 seasons. The quote they gave me was absolutely ridiculous. I then called McNally's and spoke to Brian. He was extremely knowledgable and even came out the same day to do the repair. I highly recommend McNally's because they are a trustworthy company with fair prices and they do a great job!
