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.
We had our air ducts cleaned and sanitized by McNally's and the technician was on-time, friendly, polite and respected our home. He was on schedule in terms of the time estimation it took and overall it was a great experience. This was a very different from my last duct-cleaning a few years ago with one of those "" duct cleaning companies where I had a creepy tech who kept trying to upsell me and took twice as long as the estimated time. The previous company even scratched my hardwood floors - it was such a nightmare. McNally's is professional all the way around and I really appreciate the care they take when in our home!
