There is nothing wrong with feeling as though you are not making the most out of your HVAC system. Perhaps you are aware that you have the system for a long time but now it is not giving you the performance that you wanted. This is the issue that you are going to be facing and it is one that you are not going to want to tolerate at all. You are going to want to make sure that you are resolving this matter right away. Another step that you can take is to call professional air duct cleaners in Cicero, IL if that helps.
In terms of the maintenance steps that you can take you are going to want to see if you can get someone in to clean those air ducts thoroughly. The fact is that so much dust and debris can get up there. You will find that it is a real challenge to keep those ducts clean in a way that allows air to flow through without any interruptions. You have to remember that even if you have a few ducts in your home that are not operating in the way that you expect then you are going to have some serious problems. That is why you are going to want to go ahead and make sure that you are resolving this issue.
Another step that you can take is to have someone check over the compressor for your unit. That helps a lot as the compressor is that part that goes in the outside. That is the part of your HVAC unit that produces cold air during the summer and spring months when the temperatures are hotter. If your compressor is not working then you are going to have room temperature air circulating around your house.
