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.
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.
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.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
