Very Thorough




Review of Holy City Heating & Air, LLC

The owner was here on time within 24 hours of our (non emergency) call. Our house is only 2 years old but we were experiencing very high humidity inside and couldn’t determine the reason. Tom spent hours checking everything out, making adjustments, etc. He asked us to keep in touch and let him know how things were going - over the next few days, our humidity dropped from 80% to 50% - and it’s still going down! He is clearly extremely knowledgeable and experienced - we would recommend him to anyone!

The home was experiencing humidity levels much higher than normal. Adding about a pound and a half refrigerant was all it took to drop the coil temperature, I greatly improving the humidity removal. This young lady was so happy, she gave the refrigerant from a big hug lol!
