No two heating systems break the same way, and in Ann Arbor homes the first question on any no-heat call is what kind of equipment we are dealing with. Furnaces most often quit on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve leaves the system stuck in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.
Guessing gets expensive on a cold night, so Ann Arbor HVAC handles every heating call as a diagnosis first and a repair second. Our experienced technicians measure before they replace anything: microamp flame signal, igniter resistance, pressure switch response to actual inducer draft, capacitor and motor readings, plus charge and defrost checks when the system is a heat pump. On gas equipment, safety checks are part of the routine, not an add-on. Gas connections are leak-tested, the heat exchanger is inspected, and venting is verified, because warm air from an unsafe furnace is not a fix.
We service every common heating system type across all major brands, with igniters, flame sensors, capacitors, inducer motors, and blower motors stocked on the truck, so the majority of repairs finish in one trip. If your equipment is at the end of the road, we say so honestly and walk you through the options with real numbers.

When to Call for Heating Repair in Ann Arbor
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. Watch for these telltale signs that professional help is needed:
- Some rooms warm while others stay stubbornly cold
- Energy costs climbing even though the house feels colder
- Clicking and failed ignition attempts before the furnace gives up
- Frequent on-off cycles that never bring rooms up to temperature
- An outdoor heat pump coil that stays iced over
- No warm air at the registers even with the heat turned up
- Strange smells from the vents, especially rotten egg or burning
- Banging at startup caused by burners lighting late
Early Action Saves Money
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. Call Ann Arbor HVAC at (734) 215-6957 at the first sign of trouble.

Why Hire a Professional for Heating Repair?
Combustion is what makes heating repair different from the rest of home comfort work. Delayed ignition booms unburned gas inside the heat exchanger and stresses the metal each time it happens. A cracked exchanger can leak combustion gases into the air your family breathes, and a flue that stops drafting pushes carbon monoxide into the living space instead of outdoors. None of these problems make themselves obvious to someone without training and instruments. Diagnosis has its own traps as well. Short cycling can point to a failing limit switch or to a furnace protecting itself from a clogged filter, and a flame sensor cleaned without finding out why it fouled simply sets up the next lockout.
Our experienced technicians bring instruments and judgment to both problems. Flame signal is measured, not assumed; heat exchangers are inspected; draft is verified at the flue; temperature rise is checked against the data plate so the blower speed matches the fire. On heat pumps we test defrost boards, sensors, and reversing valves rather than condemning the compressor on a hunch, and we check whether the backup heat strips have been quietly running your bill up for weeks. The repair you get is one that has been proven safe and correct under a full cycle, which is exactly what you want from anyone touching the machine that keeps your family warm.
How Our Heating Repair Works
Our systematic workflow delivers thorough, lasting results on every job. Here's a look at each step our Ann Arbor HVAC team takes:
Testing & Safety Check
We pull the fault codes, then verify: flame signal, igniter resistance, pressure switch operation, motor and capacitor health, and charge and defrost on heat pumps, with gas connections leak-tested as standard.
Findings & Upfront Pricing
You see the failed part and hear precisely why it failed, then get a firm price before any work starts. When a cracked heat exchanger or failed compressor makes replacement the smarter move, we tell you directly.
The Repair Itself
Most heating repairs wrap up in one trip. The parts that fail most often, including igniters, flame sensors, pressure switches, capacitors, and motors, are already on the truck, so the heat is back on before we head out.
Complete System Check
We run complete heating cycles, measure temperature rise against the data plate, confirm safe combustion and draft on fuel-fired equipment, and verify every safety control before we go.

A little routine maintenance goes a long way toward avoiding a mid-season breakdown. Start with these practical measures our team relies on:
- Keep chlorine products, paints, and solvents away from the furnace, because their fumes corrode burners
- Do not ignore a boom at ignition or a new rattle, since early repairs cost far less
- Keep the area around the furnace clear so the burner gets adequate combustion air
- Book a fall tune-up so worn parts are caught before the first cold night
- Make sure every level has a working carbon monoxide detector, and test it monthly
- Change the filter monthly in heating season; starved airflow trips limit switches and cracks exchangers early
- Keep heat pump outdoor units clear of snow, leaves, and shrubs so defrost can do its job
DIY vs. Professional Heating Repair
While some minor tasks like changing filters or checking a thermostat can be handled by homeowners, most HVAC work involves refrigerant, gas combustion, and high-voltage electricity, jobs that call for professional expertise. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Carbon Monoxide | An unseen hazard never gets tested | Exchanger inspected, flue draft confirmed |
| Diagnosis | Error code guessing games | Flame signal and components metered |
| Gas Connections | Fittings tightened and trusted | Every joint checked with a leak detector |
| Heat Pump Faults | An iced coil blamed on the compressor | Boards, sensors, and valves tested properly |
| Underlying Cause | Quick fix, same failure next week | The fault behind the fault diagnosed |
| Final Testing | It lit once, good enough | Complete cycles tested against the data plate |
