Direct Energy, a Houston-based service company, has a great description of how a furnace and air conditioner work together. It gives a complete picture of your systems and their main components. Check it out here.
What do you need to do to keep your furnace running at its best?
- replace the air filter once a month
- if it's more than 3 years old, have a contractor conduct yearly inspections/maintenance.
If you have any questions about how your furnace is running, contact me.
