How Much Does Furnace Repair Cost in Baltimore? [2025 Data]

Furnace repair costs in Baltimore range from $134 to $448, for an average price of $289. If your furnace has seen better days, the cost to fix it will depend on the type of damage, how much your contractor charges for labor, and a handful of other factors. This guide can help you estimate your Baltimore furnace repair costs so you know how much you’ll spend to get your heating system up and running again.

Furnace Repair Cost Factors 

Before calling an HVAC pro in Baltimore, MD, check out the following cost factors to get an idea of what you’ll pay to fix your furnace.

Repair Cost by Part

Regardless of their fuel source, furnaces are complex appliances that have a lot of working parts. Some of those parts significantly influence furnace repair costs, while others are simpler and less costly to repair.

Here is the average furnace repair cost based on the part:

Maintenance Cost

A furnace requires regular maintenance in order to operate efficiently. Otherwise, dust and other debris can clog burners, the pilot light, and other parts, causing more wear and tear on the system. 

A furnace inspection costs $80 to $100 on average, and you need to schedule an inspection at least once per year to keep your system running smoothly. An advanced inspection, which includes cleaning and a tuneup, costs $125 to $200. 

Additional maintenance costs include filters and air duct cleanings. You need to replace the filters once every 90 days, which will cost $4 to $140 per year. Schedule duct cleanings every three to five years, and expect to spend $275 to $500 for the cost of cleaning air ducts.

Cost per Hour

Furnace repairs cost $50 to $150 per hour for the labor, plus you’ll need to budget for the cost of parts. Small repairs may be billed at a $100 to $200 minimum rather than by the hour. 

One of the quickest repairs is to replace a dirty filter, which only takes a few minutes and is easy to DIY. Some of the more difficult, time-consuming parts to repair include the blower motor, the draft inducer motor, coils, and the heat exchanger.

HVAC Pro Costs

Although the bulk of your furnace repair budget will go toward parts and labor, there are a few other costs to be aware of before kicking off this project.

Licensing and Certification

In Maryland, professionals who work on furnaces (or other types of heating systems) must be registered with the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration (HVACR) Contractors. You can check a contractor’s license category and status on the Maryland Department of Labor website.

Also, before hiring a contractor to work on any part of your HVAC system (including your furnace), ask if they’re NATE-certified. It’s voluntary, but if a pro has this certification, it lets you know they have at least a couple of years’ experience in the industry, understand the latest safety protocols, and participate in ongoing training and education to keep their skills sharp.

Sales Tax

Replacement furnace parts and materials purchased in Baltimore will be subject to the city’s 6% sales tax. So, if your new heat exchanger costs $600, be prepared to pay $36 in sales tax, as well.

Tips

While there isn’t any expectation or requirement to tip HVAC professionals in Baltimore, some homeowners like to show their appreciation by tipping. If you decide to, cash is preferred, and $20 to $50 per worker is a good rule of thumb. First, though, you should confirm that the company’s policy allows its workers to take tips.

Do Furnace Repairs Increase Home Value?

You need a reliable furnace (or another type of home heating system) to stay warm in Baltimore’s freezing winters. If your current furnace is broken or struggling to heat your house effectively, repairing it can help keep you comfortable and safe.

You might also want to fix your faulty furnace if you plan to sell soon. If not, buyers could be put off by the thought of having to repair or replace it themselves. Instead, if you invest in a new HVAC system before listing your home, you could add 5% to 7% to your home’s value.
