Heating Issues
Furnace not turning on: Commonly linked to thermostat wiring issues, tripped breakers, faulty ignitors or control board failure.
Furnace blowing cold air: Often caused by pilot light problems, flame sensor failure or gas supply interruptions.
Uneven room temperatures: May result from duct balancing problems, zoning system faults or restricted airflow.
Boiler leaking water: Can stem from pressure valve failure, cracked heat exchangers or circulator pump issues.
Heat pump not switching modes: Frequently tied to reversing valve malfunctions or defrost control board problems.
Radiator not heating: Air trapped in hydronic lines, valve issues or low boiler pressure are typical causes.
Cooling & AC Issues
AC not cooling properly: Often related to low refrigerant levels, dirty condenser coils or compressor failure.
Central air making loud noises: Buzzing, banging or screeching may indicate capacitor failure, loose components or motor wear.
Frozen AC coils: Restricted airflow, clogged filters or refrigerant imbalance commonly lead to ice buildup.
Mini-split leaking water: Usually caused by blocked condensate drains or improper installation.
High indoor humidity: May signal undersized equipment, failing evaporator coils or duct leakage.
AC short cycling: Frequently tied to thermostat calibration issues, oversized units or electrical faults.
Heat pump not cooling: Refrigerant problems, reversing valve failure or outdoor unit malfunctions are common contributors.
General HVAC Problems
Poor airflow from vents: Blocked ductwork, dirty air filters or failing blower motors restrict circulation.
Indoor air quality concerns: Dust, pet dander, mold spores or VOC buildup may require filtration or purification upgrades.
Smart thermostat not connecting: Wi-Fi configuration errors, firmware issues or low-voltage wiring problems.
Rising utility bills: Aging HVAC systems, duct leaks or declining efficiency often drive higher energy costs.
Whole-house humidifier not working: Mineral buildup, solenoid valve issues or clogged water panels can reduce output.
Strange odors from vents: Musty smells may indicate mold growth while burning odors can signal electrical issues.
Frequent HVAC cycling: May point to improperly sized equipment, airflow imbalance or sensor malfunctions.

The Best Residential HVAC System for Ann Arbor Homes
The right HVAC system for an Ann Arbor home depends on square footage, insulation levels and Southeast Michigan’s temperature swings. Winter lows typically range from 16–22°F, while summer highs reach 80–85°F with noticeable humidity. For the average Ann Arbor home, roughly 1,900 square feet, a properly sized furnace and central air conditioning system or high-efficiency heat pump can deliver balanced, year-round comfort.
