Central A/C - Install
If I could give McWilliams & Son Heating and Air Conditioning zero stars, I would. My experience with this company was very disappointing. The invoice I received was significantly higher than other estimates for the same equipment, and communication throughout the process was frustrating and unprofessional. When I asked for an itemized bill to understand the charges, I was told that one would not be provided, which raised serious concerns about transparency and trustworthiness. Based on my experience, I strongly recommend getting multiple quotes from other HVAC companies before considering this one.

Quickest response yet. We thought our new thermostat (bought on Amazon) went bad when all of a sudden the house was warm right before bedtime. We called Mc Williams and Brit arrived at our home within a few hours. He diagnosed and repaired the problem very quickly. He explained everything and even showed us pictures and the part. System is up and running again. Thanks so much.

They did a good job. I live in a relatively new home, and I went through four brand new Frigidaire units then had a Rudd unit and everyone had the reversal valve go out in it. McWilliams & Son put in a Carrier air conditioner, and I've had zero problems so far. They also installed it within a day.

The sales rep showed up Monday morning and inspected the situation and gave us several options to choose from. The deal was done and a crew arrived on Friday morning along with the salesman who was working hard as well. They got everything done in one day and our house has been warm during the cold nights we've recently had in nacogdoches.
