Maryland
Air Conditioning in Maryland: what's different
Air Conditioning across Maryland depends on the climate (IECC climate zones 4–5). Mixed climates get real summers and real winters, so the AC has a full season of work and then sits idle. Spring start-up problems such as weak capacitors, low charge and clogged drains are common.
In Maryland specifically: rowhouse cooling. Older rowhouses often lack ducts, making mini-splits a common upgrade. Humid summers: Proper sizing and dehumidification improve comfort in the Chesapeake region.
Maryland licenses HVACR contractors through the State Board of Heating, Ventilation, Air-Conditioning and Refrigeration Contractors. Common systems in Maryland: Heat pumps, Gas furnace + central AC, Boilers and radiators, Ductless mini-splits.
BGE, Pepco, Delmarva Power and Potomac Edison supply electricity in different regions; BGE and Washington Gas supply natural gas in many areas.

FAQ
Air Conditioning questions in Maryland
Can I get air conditioning service anywhere in Maryland?+
Our contractor network covers many Maryland ZIP codes. Call with your ZIP code and we will tell you whether a licensed contractor serves your address.
Are mini-splits good for Baltimore rowhouses?+
Yes. They avoid running new ducts through plaster walls and can heat and cool individual floors.
How do I know if my AC needs repair or replacement?+
Age, refrigerant type and the failed part decide it. A newer system with a bad capacitor or fan motor is a repair. An older R-22 system with a failed compressor or leaking coil is usually a replacement.
Why is my AC running but not cooling?+
Common causes are a dirty filter or coil, low refrigerant from a leak, a failed outdoor fan or capacitor, or a frozen indoor coil. Turn the system off if you see ice and call for a diagnosis.
