Summit Heating & Air Conditioning came in to service our AC unit. They also looked to see if there were any issues and added freon. They went through everything very thoroughly and explained everything to us. Sometimes our AC unit gives off that musty smell and they added some type of spray to the unit that makes our office smell wonderful! It's a new thing they are trying out and we absolutely love it! They were on time and very professional. Just real pleasant to work with!
