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
Responded to a no-heat call on a Rheem gas furnace that would not light, and inspected the unit, including the ignition sequence, gas supply, venting, and surrounding clearances. Identified and corrected the cause of the ignition failure, restoring normal heating operation. Verified proper burner ignition and flame, steady operation through a full heating cycle, and measured and documented installation clearances; no frost, rust, or visible damage was found.
Performed scheduled tankless water heater maintenance visit as part of recurring service. Additionally conducted a courtesy visual inspection of the crawlspace, which showed the sump basin with sealed lid and vapor barrier properly installed, PVC discharge piping secured with strap hangers, and a float switch in place, with no standing water or visible issues observed.
Completed seasonal heating maintenance on the gas-fired system, including replacement of the air filter with the customer-supplied filter. Performed combustion analysis at the flue, with readings of 8.3% O₂, 7.1% CO₂, 39 ppm CO, 95.4% combustion efficiency, and 101°F stack temperature, confirming the unit is operating within normal parameters.
Installed a new upright gas furnace as part of a complete HVAC system replacement, with PVC combustion air and exhaust venting routed from the unit through the utility space. Verified proper clearances, connections, and control panel setup, and confirmed the adjacent water heater remains insulated and secured.
Performed a heating maintenance visit, measuring amperage draw with a clamp meter on the system's electrical supply conductor to verify proper operating current. Confirmed thermostat operation in Heat mode with Fan set to Auto, with the Wi-Fi-enabled unit displaying a stable 71°F room temperature and no signs of damage or abnormal conditions. The heating system was found operating normally and the repair was completed.
Replaced the defective AprilAire 8120-series ventilation controller on the Model 8145 fresh air ventilation unit under manufacturer warranty, using the pre-ordered replacement part. Verified the new controller powered up and displayed normal operating status, with the ventilation cycle set to 15 min/hr. The removed controller is to be returned to the counter per warranty requirements.
Performed seasonal heating maintenance on the split system, inspecting the outdoor condenser unit and indoor air handler. Verified the condenser was clean and free of debris, frost, or damage, and confirmed the electrical disconnect and conduit were secure. Checked the 16x25x4 media filter and housing, inspected the PVC condensate drain and refrigerant line insulation, and noted residue buildup at the drain termination point and surface corrosion on the sheet metal base pan for monitoring.
Performed a heating system inspection and combustion analysis on the gas furnace, with flue gas readings measured at O₂ 8.5%, CO 16 ppm, CO₂ 8.2%, stack temperature 106°F, and 93.7% efficiency, indicating normal, safe operation. Inspected the PVC condensate and venting assembly and flexible gas connections, and left the foil tape on the PVC condensate piping temporarily removed so it can be replaced after the condensate test.
Performed a tune-up on the gas furnace system, including inspection of the furnace cabinet, wiring, and control board, and measured static pressure with a digital manometer (+10.33 in. W.G. reading recorded). Completed combustion analysis on natural gas, recording O₂ 6.6%, CO 38 ppm, CO₂ 8.0%, stack temperature 107°F, and 95.0% efficiency, confirming the unit is operating within normal parameters.
Performed scheduled heating maintenance on two gas-fired systems, including combustion analysis with a Bacharach Insight Plus analyzer. The first unit recorded O2 7.9%, CO 36 ppm, CO2 7.4%, 94.8% efficiency, and 106°F stack temperature, and the second recorded O2 12.0%, CO 11 ppm, CO2 5.0%, 97.0% efficiency, and 90°F stack temperature. Both units tested within acceptable CO limits and were left operating properly.
Completed first-time winterization of a two-bathroom vacant residence listed for sale, with electric service on and thermostat held at 55°F in heat mode. The refrigerator was powered off with all doors and the freezer drawer left open to prevent mold and odor. Thermostat displayed a communication error while maintaining its setpoint.
