Furnace Tune-Up in Harford County: What to Do Before Winter

by Josh Tessier

Get your furnace tuned up once a year, in the fall, before you need the heat. Change or check the filter every month, and swap it at least every 3 months. BGE has a free HVAC tune-up program. BGE says it is awaiting a PSC decision about extending its programs into 2027. Check the tune-up page or call 877-685-7377 for current availability.

ENERGY STAR says a dirty filter slows air flow and makes the system work harder, and regular maintenance helps the system run efficiently.

When should I get my furnace tuned up?

ENERGY STAR says to get your heating checked every fall and your cooling checked every spring. An easy way to remember: book it when the clocks change.

In Harford County, that means October or early November, before the first cold snap.

What should the tech check?

ENERGY STAR says a good heating check-up covers:

Gas (or oil) connections and gas pressure.
The burner and how it burns.
The heat exchanger. A cracked one can leak carbon monoxide.
Electrical connections and the thermostat.
Moving parts, oiled so they don't wear out.
The drain line, so it doesn't clog.

Ask for a carbon monoxide check too. BGE lists a carbon monoxide check as part of its furnace tune-up.

What can I do myself?

Check the filter every month. Change it at least every 3 months. A dirty filter makes the furnace work harder and cost more.
Seal your ducts. ENERGY STAR says sealing and insulating ducts can make your system up to 20% more efficient.

Is the BGE free tune-up still available?

Check BGE's tune-up page or call 877-685-7377 for current availability before you count on it. Here is what the page says:

It is free for BGE residential customers.
BGE says it is awaiting a decision by the Maryland Public Service Commission (PSC) about extending its programs into 2027.
Your system must be working. Tune-ups are meant for systems more than 3 years old.

Check BGE's page or call 877-685-7377 for current availability.

BGE also has rebates on new heating and cooling equipment. Its page says new equipment must be installed by December 31, 2026. The Maryland Office of People's Counsel says BGE's gas EmPOWER programs phase out by the end of 2026. If you are planning a new system, check these dates with your contractor.

When should I replace my furnace?

ENERGY STAR says to have your system evaluated by a professional if it is more than 10 years old or not keeping your house comfortable.

If you plan to sell in the next few years, keep your service records. Buyers and home inspectors often ask about the age and condition of the heating system. I cover that more in what to do before selling your home.

Can I get help paying my heating bill?

Yes. Harford County residents can apply for the Maryland Energy Assistance Program (MEAP) and the Electric Universal Service Program (EUSP) through the Harford Community Action Agency.
