Furnace Repair Cost Factors

There are a number of factors to take into account when estimating the cost of a furnace repair.

Warranty – If you have a furnace that is still under warranty then you may have the cost of parts covered. When your furnace is no longer under warranty, the costs will depend on the parts you need replaced. You can find the average costs of common replacement parts below.
Service – Typically, you should expect to pay for service visit and labor of the contractors.
Age, Size and Condition – How old your furnace is, how large it is and how it is running will all factor into the costs you face for repairs.

Service Fees for Furnace Repair

Furnace repair contractors typically charge a fee for a heating repair visit. This covers the cost of the furnace inspection and diagnostics to accurately identify the problem or problems your furnace faces. Furnace repair service fees vary between contractors, but costs typically range from $50 to $100. Many times, a furnace can be repaired in one visit, but if components need to be ordered, it may take some time to get your heating system back up and running.

If your furnace breaks down overnight, on the weekend, or during the holidays, expect to pay a higher service fee for emergency furnace repairs.

Avoiding Furnace Repairs

Your best defense to avoid furnace repairs and their expense is preventative maintenance.

Furnace maintenance costs vary from one contractor to the next, and many HVAC companies offer specials for preventative maintenance plans to keep homeowners current with their heating maintenance needs. Expect to pay around $100 for a preventative maintenance tune-up.
