History Of Frankford
The area was populated as early as 1750 under the local name of Forest Flower. In 1775, it was deeded to a plantation in a land grant under the name of Partnership. It became known as Jacob’s Mill Pond around 1800. In 1808, the community became commonly known as Long’s Store on Vine’s Branch when plantation owner David Long constructed a country store at the location. Many people knew the area as Gum’s Store in 1812. This is presumably because the ownership of the store had changed, but the precise details are not clear. It became known as Frankford around 1820 and was officially given that name in 1848 when a post office was established at Frankford Village. The Town of Frankford became an incorporated municipality in 1337.
The arrival of the Pennsylvania Railroad heralded rapid growth in Frankford. A hotel opened, as did a local opera house, and Frankford became the center for business and cultural events in the area. Noteworthy sea captains made their homes in Frankford, and three of those homes are still in existence. In 1979, the Captain Ebe Townsend Chandler house was added to the National Register of Historic Places. It now operates as the Captain Chandler House Bed and Breakfast Inn.
Area Attractions
The Assawoman Bay State Wildlife Area, a popular destination for East Coast birdwatchers, is located seven miles east-southeast of Frankford. An observation tower and photography blind are located within the wildlife area, and loblolly pine forests make it a refuge for land birds as well as the expected waterfowl.
The Delaware Seashore State Park, nearly 3,000 acres of beaches and a barrier island, is located just 10 miles to the east of Frankford. The park is open to Delaware’s Atlantic Coast on the east and bounded by the bays of the Rehoboth and Indian Rivers to the west. It is a major attraction in the region and receives millions of visitors each year.
Frankford is also quite close to the Pocomoke State Forest. This forest, which has a plan to become a national model for certified sustainable forestry, is comprised of 17,676 acres of land that was once cleared for farming. The land was reacquired by the federal government during the Great Depression and deeded to Delaware in 1954. The park contains approximately five acres of old growth forest that had escaped felling when the area was farmed.

Job Locations and Reviews
Performed an indoor air quality inspection in response to a musty odor near the water heater, evaluating the condensate drain line for blockage and verifying heating system operation. Combustion analysis in heating mode returned O₂ 12.7%, CO 78 ppm, CO₂ 5.4%, 96.6% efficiency, and 89°F stack temperature, confirming the system is operating properly. Inspection of the duct/plenum interior revealed heavy microbial growth on the fibrous insulation board, indicating a likely source of the odor and a need for remediation.
Performed scheduled heating maintenance on a natural gas furnace, including a combustion analysis with a calibrated flue gas analyzer. Readings were within acceptable limits: O2 7.9%, CO2 7.3%, CO 24 ppm, stack temperature 93°F, and combustion efficiency 97.5%, confirming safe and efficient operation. The system was left operating properly.
Performed scheduled heating maintenance visit on the system, inspecting the equipment in the utility closet and verifying proper installation of the water heater, including the drain pan and the expansion tank with flexible stainless connectors. Documented unit and clearance dimensions (approximately 24" W x 48" T) and confirmed associated piping and electrical connections were in serviceable condition.
Performed a scheduled seasonal heating maintenance visit on the propane-fired system. Conducted combustion analysis with a Bacharach analyzer, recording O₂ at 8.2%, CO at 44 ppm, CO₂ at 8.4%, and stack temperature of 84°F, and documented the results for the maintenance record. Combustion readings indicate the unit is operating with acceptable CO levels, though the elevated excess air and low stack temperature warrant monitoring at the next visit.
Performed seasonal heating system inspection and operational check on two heating systems, including a tankless water heater. Conducted combustion analysis on natural gas-fired equipment using a Bacharach Insight analyzer, recording O₂ at 14.1%, CO at 21 ppm, CO₂ at 3.9%, stack temperature of 106°F, and combustion efficiency of 88.8%. Verified safe CO levels and proper operation of both units.
Performed annual maintenance on a wall-mounted tankless water heater, including a heat check and a descaling flush using a recirculation setup with isolation valves and a bucket. Inspected the water and gas connections, regulator, shutoff valves, and venting, and found no leaks, corrosion, or visible defects.
Performed scheduled heating maintenance on the tankless water heater and heating system, completing combustion analysis with a calibrated analyzer on propane. Readings recorded: O₂ 8.8%, CO 73 ppm, CO₂ 8.0%, stack temperature 100°F, and combustion efficiency 95.4%, confirming the appliance is operating within acceptable parameters.
Performed a tune-up and inspection on one HVAC system, including a tankless water heater inspection. Combustion analysis was conducted with an electronic analyzer, recording O₂ at 10.1%, CO at 54 ppm, CO₂ at 7.1%, stack temperature of 96°F, and combustion efficiency of 96.3%. System operation was verified and the equipment was left in working condition.
Performed an IAQ estimate for installation of a crawl space dehumidifier in a roughly 3-year-old home with no existing unit. Inspected the horizontally mounted Lennox air handler, insulated flex ductwork, foil-wrapped plenum, refrigerant lines, and PVC condensate drain, and found no visible frost, rust, or damage. Reviewed crawl space dehumidification and whole-home air purification options, including solutions comparable to the customer's current APCO RT system, to support a proposal.
