When the heat goes out in Palatine, IL, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the most common no-heat call we run is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down three tries later and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil buried under frost, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.
Fault codes are where our diagnosis starts, not where it ends. On every no-heat call, Palatine HVAC backs up the board's story with measurements: flame signal read in microamps, igniter resistance checked, the pressure switch tested against real inducer draft, capacitors and motors metered, and, on heat pumps, refrigerant charge and defrost operation verified. Any visit that touches the gas side also covers the safety basics. We leak-test the connections, look over the heat exchanger, and confirm the flue is drafting, since a repair that has not been proven safe is not a finished repair.
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 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 Palatine
Recognizing the warning signs early can save you time, money, and prevent significant damage to your property. These are the signals our technicians see most often when a problem is underway:
- The system starting and stopping every few minutes without warming the house
- Booming or banging at ignition, a sign of delayed burner light-off
- A heat pump's outdoor unit encased in frost or ice
- Energy costs climbing even though the house feels colder
- Cold air, or no air at all, when the thermostat calls for heat
- A rotten-egg, burning, or musty smell once the heat kicks on
- Uneven heat, with certain rooms that never warm up
- The furnace clicking and trying to light but shutting back down
Don't Wait for a Total Failure
Most HVAC failures start small, a weak capacitor, a squealing blower, a system that runs a little longer each week. At the first hint of a problem, reach out to Palatine HVAC at (224) 395-7757 for a fast inspection.

Why Professional Heating Repair Matters
Some of the most dangerous 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. Clean a flame sensor without asking why it fouled, and the next lockout is already on the calendar.
Instruments and judgment are what our experienced technicians bring to both sides of that problem. We measure the flame signal instead of assuming it, inspect the heat exchanger, verify draft at the flue, and check temperature rise against the data plate so the airflow matches the fire. With heat pumps, the defrost board, sensors, and reversing valve are tested before anyone condemns a compressor, and we look at whether the backup strips have been running up your bill for weeks. Each repair we complete is proven safe and correct over a full heating cycle, which is the standard you should expect from anyone working on the equipment 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 Palatine HVAC:
Testing & Safety Check
Fault codes are only the starting point. We measure flame signal and igniter resistance, test the pressure switch, check motors and capacitors, verify charge and defrost on heat pumps, and leak-test the gas connections on every visit.
Clear Findings & Upfront Quote
We show you what failed and why, and give a firm price before work begins. If a cracked heat exchanger or dead compressor changes the math toward replacement, we say so plainly.
Same-Visit Repair
Because we stock igniters, flame sensors, pressure switches, capacitors, and motors, most repairs are finished on the first visit, and your home is warming up before we pack up.
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.
Not Sure What You Need?
Our experienced technicians can assess your situation and recommend the best solution.

Taking preventive measures can help you avoid costly heating and cooling problems down the road. Start with these practical measures our team relies on:
- Have the system serviced each autumn, before the weather tests every weak component
- 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
- Test carbon monoxide detectors monthly and put one on every level of the home
- Never store paints, solvents, or chlorine products near the furnace; their vapors corrode the burners
- Change the filter monthly in heating season; starved airflow trips limit switches and cracks exchangers early
- Give the outdoor heat pump unit open space, free of snow drifts and plantings, so it can defrost
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 | Invisible risk goes unchecked | Heat exchanger and draft verified |
| Troubleshooting | Error code guessing games | Flame signal and components metered |
| Gas Safety | Fittings tightened and trusted | Instrument leak testing as standard |
| Heat Pumps | An iced coil blamed on the compressor | Defrost controls and reversing valve tested |
| Underlying Cause | Symptom treated, problem left behind | The reason it failed tracked down |
| Final Testing | It lit once, good enough | Complete cycles tested against the data plate |
