When was the last time you changed your air filter?
Depending on the quality and style of your furnace filter you may need to replace it monthly or every 3 months. Having the proper size and sticking to the right replacement schedules helps not only the system to function better but also improves the quality of air in your home!

You’ll probably never see your heat exchanger. It works quietly behind the scenes, keeping heat flowing and harmful gases safely contained.
During your annual furnace tune-up, this is one of the key components we inspect to make sure everything is operating safely and efficiently.
If it’s been a while since your last maintenance check, now’s a good time.
