Trying to maintain a comfortable temperature in your commercial building during the summer can be expensive. The fact that the door is opened and closed more frequently than that of a home, the vast difference in space, and the increased amount of people creating body heat all mean that the AC unit needs to work hard to keep things cool. It will be up to you to make sure that the system maintains high efficiency to keep the electric bills reasonable. Here are a few tips for making sure you get the most out of your AC for the least amount of energy usage.
While you know how important it is to keep the filters of your home unit clean, it is even more important to do so in a commercial system. Because of all the people and the opening and closing of the doors, more dust and debris is in the air that will be sucked into the vents and the filters. You will need to check the filters regularly—weekly is not too often—and change or clean them as necessary. Without clean filters, the air cannot flow properly and the whole system gets bogged down.
It is imperative that you contact a service company at the first sign of trouble. If you hear strange noises, notice that the system is running more frequently, or have a bill larger than you expected, there could be trouble. Do not wait until the unit is blowing hot air or not turning on at all. The sooner you have someone out to fix the problem, the less of a problem it will be. The only thing that ever happens when you wait to have an air conditioner fixed is more things break down and the higher the repair bill will be.
You should have exhaust fans installed in ceiling crawl spaces to help get rid of some of the heat. Hot air rises, so if you can pull it all out of the building, there will be less hot air to cool down.
Keep an eye on the thermostat and make sure the temperature is set low enough to be comfortable, but not so low that you are wasting energy. Set the temperature a bit higher when you leave the building for the night, but be sure to turn it back down first thing in the morning before things start to get warm.
If you have any concerns as to whether your system is running efficiently, have a commercial air conditioning technician come to inspect it. The better the system runs, the more money you will save.
