How often should I schedule furnace maintenance?
Professional furnace tune-ups should be scheduled at least once a year to ensure your maximizing the benefits. The ideal time to schedule it is in the fall, before the winter weather fully hits.
Can I repair a furnace by myself?
We always recommend calling a professional for furnace repairs! While DIY videos may make a fix seem easy, you can actually cause more damage to your furnace if you’ve inaccurately diagnosed a problem. If you attempt a repair without the proper tools and training, you can also put yourself and your home at significant risk.
When should I have my furnace replaced?
Furnaces typically last around 15 years, so if your furnace is older than that, a replacement may be due. Other signs that you should have a new furnace installed include high energy bills due to an inefficient system and if your furnace has needed frequent repairs.
