No two heating systems break the same way, and in Evansville homes the first question on any no-heat call is what kind of equipment we are dealing with. Furnaces most often stall 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 underperforms lets ice build up on the outdoor coil, a bad reversing valve traps the system 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.
Evansville HVAC runs every no-heat call diagnosis-first. Our experienced technicians read the board's fault codes and then verify them, measuring flame signal in microamps, testing igniters for resistance, confirming pressure switch operation against actual inducer draft, metering capacitors and motors, and checking refrigerant charge and defrost operation on heat pumps. Gas-side visits include the safety fundamentals as standard practice: connections are leak-tested, the heat exchanger inspected, and flue draft confirmed, because a heating repair that is not verified safe is not finished.
We service gas and electric furnaces, heat pumps, air handlers, boilers, and ductless systems across all major brands, with igniters, flame sensors, capacitors, inducer motors, and blower motors stocked on the truck, so most homes have heat again the same visit. 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 Evansville
Catching these issues early helps you avoid costly problems and protect your property. Watch for these telltale signs that professional help is needed:
- A heat pump's outdoor unit encased in frost or ice
- Heating bills spiking while comfort keeps falling
- No warm air at the registers even with the heat turned up
- Strange smells from the vents, especially rotten egg or burning
- Some rooms warm while others stay stubbornly cold
- Short cycling every few minutes while the house stays cold
- A furnace that tries to light, clicks, and then quits
- A loud boom when the burners light, which points to delayed ignition
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. Call Evansville HVAC at (812) 203-4231 at the first sign of trouble.

Why Hire a Professional for Heating Repair?
The most serious heating failures are the ones nobody notices. A cracked heat exchanger can send combustion gases into the supply air, a blocked or failing flue can spill carbon monoxide into the house, and a furnace that lights late booms gas inside the exchanger, weakening it a little more every cycle. Without instruments, none of it is easy to spot. Even routine symptoms can mislead: a short-cycling furnace may have a bad limit switch, or it may simply be shutting down to protect itself from a choked filter. And a flame sensor cleaned without a look at why it fouled will foul again.
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.
Our Heating Repair Process
We follow a proven process to ensure every repair and installation is completed to the highest standards. Here's what you can expect when you choose Evansville HVAC:
Diagnosis and Safety Check
Every visit begins with measurements, not guesses: flame signal, igniter resistance, pressure switch response, and motor and capacitor health, plus refrigerant charge and defrost on heat pumps. Gas connections are leak-tested as a matter of course.
Findings & Upfront Pricing
Before we pick up a tool, we walk you through what broke, why it broke, and what it will cost. And if the findings, like a cracked heat exchanger or a dead compressor, point toward replacement, we say so plainly.
Expert Repair
Igniters, flame sensors, pressure switches, capacitors, and motors ride on our trucks, so most heating repairs are completed the same visit and the house starts warming before we leave.
Full Cycle Verification
We do not call it done until the system proves itself. That means full cycles, temperature rise checked against the data plate, combustion and draft confirmed on gas equipment, and every safety control verified.
Heating Repair Prevention Tips
Smart maintenance is almost always cheaper and easier than an early replacement. Start with these practical measures our team relies on:
- Call about booming at startup or new rattles right away, while the fix is still inexpensive
- Give the outdoor heat pump unit open space, free of snow drifts and plantings, so it can defrost
- Replace filters monthly through the heating season to keep airflow strong and the heat exchanger from overheating
- Test carbon monoxide detectors monthly and put one on every level of the home
- Schedule a professional tune-up every fall before the first cold snap finds the weak parts
- Keep chlorine products, paints, and solvents away from the furnace, because their fumes corrode burners
- Leave open space around the furnace so the burners can draw enough combustion air
DIY vs. Professional Heating Repair
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Here's a comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Carbon Monoxide | An unseen hazard never gets tested | Exchanger inspected, flue draft confirmed |
| Troubleshooting | Error code guessing games | Flame signal and components metered |
| Gas Safety | Small leaks slip by undetected | Instrument leak testing as standard |
| Heat Pumps | Defrost problems misread as total failure | Defrost controls and reversing valve tested |
| Underlying Cause | Quick fix, same failure next week | Cause found, not just the symptom |
| Final Testing | It lit once, good enough | Complete cycles tested against the data plate |
