- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate state (sub-zero winter design temps): equipment must be sized for severe heating loads, and a local mechanical permit/inspection is required for installs and changeouts under the Michigan Mechanical Code.

Furnace Repair in Dearborn, explained.
What Drives Furnace Repair Costs in Dearborn?
Repair costs in Dearborn depend on the part needed, labor rates, and whether a permit is required. Older homes (median built 1952) may have outdated systems that are harder to service. The need for a mechanical permit (required for major repairs) adds a small fee but ensures code compliance. Labor rates reflect the local market, and emergency after-hours calls typically cost more. The type of system—gas furnaces are common—also affects pricing, as some components are more expensive.
Common Furnace Problems in Dearborn
Flame sensor failure
A dirty or faulty flame sensor is a frequent issue in older furnaces, causing the system to cycle on and off.
Igniter malfunction
The igniter can wear out over time, especially in systems that have been used for many heating seasons.
Blower motor problems
Blower motors may fail due to age or dust buildup, reducing airflow and heating efficiency.
What to Expect During a Furnace Repair in Dearborn
A technician will first diagnose the issue (diagnostic fee $80–$225). For major repairs, a mechanical permit must be pulled from the local building department. The repair itself may take a few hours, and the technician will test the system afterward. If the heat exchanger is cracked, replacement can be costly ($1,650–$3,800+), and a permit and inspection are required.
