Furnace lights then shuts down after a few seconds

Heating and air conditioning service built around Baltimore
We treat 21218 as a dedicated service zone. Hot humid summers and winter cold snaps keep both heating and cooling in regular use. Because the equipment here works hard for a long season, we lean heavily on catch-it-early diagnostics rather than emergency replacements.
Because Maryland swings between seasons quickly, a lot of our Baltimore calls come in the first hot or cold snap of the year — systems that sat idle for months and then get asked to run flat out.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Baltimore21218 HVAC questions, answered
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Baltimore see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
Why is my furnace short cycling?
Short cycling in Baltimore most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in Maryland is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
What brands do you service in Baltimore?
All of them. Our 21218 technicians are trained on American Standard, Lennox, Trane, Mitsubishi Electric and essentially every other residential brand sold in Maryland, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
