Setting up for a holiday party with a clean HVAC system

My family loves holidays. The first thing we do when we know a holiday is coming up is decorate our home. It is fun for our family. We go to the store and pick out the decorations and then we hang them up. Then throughout the month we do crafts and read books that have to do with the holiday. The last thing we do is throw a party for the holiday. We invite all of our friends and family. One of the most important things we do before a party is get our HVAC system looked at. We had a party one time where our HVAC system broke down. The party was awful. It was super hot and there was nowhere to escape the heat. Every one of our guests was sweating profusely. I felt terrible. It was a holiday so there were no HVAC workers working in the area. I had to deal with it until the next day when I could call. Now they come to the house and clean the system. They look for any and all defective parts. We do not know of these parts until they make our systems break down. Ever since we have done this we have never had an issue with our HVAC system. Our system is always nice and clean. I do not need to clean my house as often because my house vents are clean. This makes it easier to set up for a party as well. I know all of my guests will be happy and comfortable in my home for the party.
