You can avoid many of the most common heating system problems by performing regular maintenance or tune-up on your system. The right knowledge and a little bit of effort can go a long way in keeping your HVAC system running efficiently and avoiding future breakdowns.
Get a professional tune-up on a yearly basis. By far, the best thing you can do to ensure that your furnace performs to the best of its ability is to schedule a professional tune-up every year. 
During a tune-up, our technicians will inspect your furnace for any operational problems and perform a number of maintenance tasks (like cleaning your system) that will help avoid future breakdowns.
You should keep your air filter clean. A dirty filter will cause all sorts of performance and efficiency problems. Avoid it! How? Only check or check your filter one a month.
Don’t forget to check your CO detectors.
