Heating and cooling service in Trumbull, CT
Trumbull's postwar colonials and raised ranches are a short drive from our Bridgeport office.
BDM Mechanical repairs, replaces and maintains furnaces, boilers, central air and heat pumps in Trumbull, CT. Trumbull borders Bridgeport's North End, close to the Brookfield Ave service office, so most calls here are quick to reach, and the phone is answered every hour of the day.
Postwar houses and ducts sized for heat
Most of Trumbull was built after the war: colonials, capes, split levels and raised ranches in Nichols, Long Hill and Daniels Farm, many now on their second or third furnace and first or second central air system. Those houses tend to have ductwork that was sized for heating alone and asked to carry air conditioning later, which is why upstairs bedrooms run warm in July.
Basement furnaces feeding attic air handlers, original ductwork and aging oil tanks are the common threads here. Many homes have switched from oil to gas or are weighing a heat pump, and we lay out the options with real numbers for that house rather than a standard pitch.

Calls from Trumbull reach the same 24/7 line as every other call. The person who answers takes the address and what the system is doing, and the job goes to the Brookfield Ave service office in Bridgeport, which covers Trumbull on routine runs. If that schedule is full on a cold night, the Guilford head office takes it and you are told before anyone is sent.
Have the system type, the fuel and any error code or noise ready when you call. That is usually enough to bring the right parts on the first visit.
