About HVAC service in Baltimore

Baltimore HVAC questions, answered
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Baltimore, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Baltimore we see algae and dust clogging drain lines constantly during May through September. It is a fast fix but ignoring it ends in ceiling damage.
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.
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.
Why is my system 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.
