Coleman Evcon DGAT056BDC furnace Parts

Replacing a 60,000 BTU furnace (similar in size to many Coleman Evcon furnace setups like model DGAT056BDC) typically costs about $3,500 to $8,500 installed, depending on efficiency level, venting changes, and labor in your area.

A furnace replacement price is usually a bundle of equipment plus installation work. The biggest cost drivers are:

• Furnace efficiency (AFUE): higher-efficiency units cost more and may require different venting.
• Venting and combustion air: PVC venting, chimney liner work, or intake piping can add cost.
• Gas line and shutoff updates: resizing, sediment trap, or code-related changes.
• Electrical and controls: new disconnect, wiring repairs, thermostat compatibility.
• Ductwork condition: sealing, transitions, or return-air improvements.
• Permits and inspections: varies by city and county.

These ranges are common for a 60,000 BTU class gas furnace replacement.

These items help you compare quotes accurately and avoid surprise add-ons:

• Confirm the BTU size and airflow needs (oversizing can cause short cycling).
• Ask whether the quote includes new venting and condensate drain (if applicable).
• Verify whether a new thermostat is required.
• Check if the installer is including a new filter rack or return-air fixes.
• Make sure permits and startup testing (combustion check, temperature rise) are included.

A 60,000 BTU furnace replacement is not just swapping a box. Efficiency level, venting, and duct compatibility affect comfort, safety, and operating cost. Getting the sizing and installation details right usually matters more than the brand name.

A 60,000 BTU furnace typically heats about 1,200 to 2,000 sq. ft. in many homes; the real coverage depends on climate, insulation, air leakage, ceiling height, and duct design. For a Coleman Evcon furnace like model DGAT056BDC, sizing is best confirmed with a load calculation.

Use these common ranges to sanity-check whether 60,000 BTU is in the ballpark:

• Cold climates or drafty/older homes: closer to 1,200 to 1,500 sq. ft.
• Moderate climates with average insulation: about 1,500 to 1,900 sq. ft.
• Mild climates and tight, well-insulated homes: up to 2,000 sq. ft.
• High ceilings (vaulted, 9 ft+): reduces effective coverage
• Leaky ducts or undersized returns: reduces delivered heat to rooms

“Square feet per BTU” is not fixed because your home’s heat loss drives the required furnace output. Two homes with the same floor area can need very different BTUs.

• Outdoor design temperature (your winter lows)
• Insulation levels (attic, walls, rim joists)
• Window type and air sealing
• Ceiling height and open floor plans
• Duct leakage and airflow balance

A common shortcut is BTU per sq. ft. (very approximate):

Correct sizing helps your DGAT056BDC run longer, steadier cycles for comfort and efficiency. Oversizing can cause short-cycling and uneven temperatures; undersizing can struggle on the coldest days.

If your Coleman Evcon furnace model DGAT056BDC turns on (you hear it running) but does not heat, the blower is usually operating while the burners are not igniting or not staying lit. The most common causes are thermostat setup, restricted airflow (dirty filter), or an ignition or flame-sensing problem.

• Confirm the thermostat is set to Heat (not Cool or Fan On) and raise the set temperature 3 to 5 degrees.
• Replace the air filter if it is dirty; a clogged filter can trip the high-limit and stop heat.
• Verify the furnace service switch is on and the circuit breaker is not tripped.
• If you have a standard-efficiency furnace, make sure the intake and exhaust are not blocked.
• If the furnace starts, then shuts down quickly, watch for a blink code on the control board (through the sight glass or panel opening).

In most DGAT056BDC-STYLE gas furnaces, the heating sequence is: inducer starts, igniter heats (or spark starts), gas valve opens, burners light, flame is proven, then the blower runs. If the furnace never heats, the failure is typically in the ignition or safety chain.

A furnace that runs without heating is often shutting down on a safety check (flame proving, pressure switch, or high-limit). Fixing the root cause prevents repeated cycling, poor comfort, and unnecessary wear on the igniter, control board, and blower.
