The AC Problems Palatine Homeowners Face Most
Palatine’s housing ranges from 1960s colonials along Northwest Highway to the newer townhome communities near Deer Grove and the subdivisions south of Dundee Road. That diversity in home age and construction style produces a correspondingly wide range of cooling system failures:
- TXV valve failures in mid-efficiency systems: Thermostatic expansion valves regulate refrigerant flow into the evaporator coil. When they stick open or closed, which is common in systems 8 to 15 years old, the result is either a frozen coil or severely reduced cooling output. TXV replacement is not a quick repair, it requires recovering refrigerant, soldering, and recharging the system. We schedule this as a dedicated service appointment.
- Compressor overheating from restricted condenser airflow: Palatine homes with privacy fencing, decking, or enclosed patios around the outdoor unit often restrict the condenser’s ability to dissipate heat. The compressor overheats, the high-pressure switch trips, and the system shuts down. We identify the restriction, restore airflow, and verify compressor integrity.
- Ductwork leaks in attic-ducted systems: Several Palatine neighborhoods feature homes with ductwork routed through unconditioned attic spaces. Joints pull apart over time due to thermal expansion, and the result is conditioned air dumping into the attic instead of the living space. We test duct pressure and seal or repair compromised sections.
- Electrical contactor pitting: The contactor is an electromechanical switch that energizes the compressor and fan. Over thousands of on-off cycles, the contact points pit and erode, eventually preventing the circuit from closing. This is a common and inexpensive repair—but it stops the entire system until addressed.
- Incorrect thermostat wiring from DIY upgrades: We regularly encounter Palatine homes where a homeowner or handyman installed a new thermostat without properly mapping the existing wire configuration. Crossed wires cause the system to run in heating mode, fail to engage the compressor, or blow the low-voltage fuse on the control board.
- Condensate pump failures in slab-on-grade homes: Homes without a gravity drain path require a condensate pump to remove the water produced by the evaporator coil. When the pump fails, the backup float switch shuts down the system to prevent flooding. We replace the pump and test the float switch to confirm proper safety operation.

Frequently Asked Questions — AC Repair in Palatine, IL
Reset the breaker once. If it trips again immediately, do not reset it a second time—this indicates a short circuit, a ground fault, or a compressor pulling excessive current, all of which require professional diagnosis. Call us at (847) 338-2777 and avoid running the system until it has been inspected.
A refrigerant recharge addresses the symptom (low charge) but not the cause (a leak somewhere in the system). Any reputable technician who adds refrigerant should also locate and repair the leak. If a previous contractor simply topped off your system without finding the leak, the problem will return.
For most Palatine homes, yes. A two-stage or inverter system runs on low-stage during moderate demand, using less energy and maintaining steadier temperatures. It switches to high-stage only during peak heat. The result is lower utility bills, better humidity control, and a quieter home.
Proper sizing depends on square footage, insulation levels, window count and orientation, ductwork capacity, and local climate data. We perform a Manual J load calculation—the industry standard—to determine the correct capacity. An oversized unit short-cycles and fails to dehumidify; an undersized unit runs nonstop without reaching set point.
Standard one-inch filters should be replaced every 30 to 60 days during cooling season. Four-inch media filters last three to six months. A clogged filter restricts airflow, reduces efficiency, and is the most common preventable cause of AC problems we encounter.
Yes. Our maintenance agreements include annual tune-ups, priority scheduling, and discounted repair rates. Contact us to discuss which plan fits your needs.
