Local Expertise: Our technicians know Carnegie’s homes and weather patterns, ensuring tailored solutions for every mini split make and model.
Certified Professionals: All repairs are performed by EPA-certified refrigerant handlers with ongoing training in advanced diagnostic tools.
Transparent Estimates: You’ll receive a clear overview of labor requirements, parts needs and anticipated costs before work begins—no surprises on your final invoice.
“Once-and-Done” Guarantee: We stand behind our workmanship. If a repaired component fails again within 90 days, we return at no additional labor charge.

Refrigerant Leaks Symptoms: insufficient cooling, ice buildup on the evaporator coil, hissing sound near indoor or outdoor unit.
Drainage & Condensate Clogs: water pooling beneath the indoor unit, musty odors, occasional shutdowns from overflow switches.
Fan & Motor Malfunctions: rattling or grinding noises, reduced airflow, indoor-unit fan failing to start or stopping mid-cycle.
Electrical or Control Faults: unit fails to respond to remote or wall controller, random power cycling, error codes flashing on display.
Compressor Issues: outdoor-unit vibrations, humming without startup, intermittent cooling performance.

Check for visible oil spots or frost lines indicating refrigerant escape.
Inspect piping, fittings and quick-connect joints for corrosion or physical damage.

Employ precision gauges to verify system pressures against manufacturer specifications.
Use electronic leak detectors and ultraviolet dye where applicable to pinpoint micro-leaks.

Test capacitors, contactors and wiring harnesses for continuity, voltage integrity and proper grounding.
Calibrate control board connections and verify correct communication between indoor and outdoor modules.

Examine blower wheel, air filters and evaporator coil for dirt buildup affecting performance.
Confirm proper refrigerant superheat and sub-cooling levels to ensure optimal heat transfer.

After repair, run system through multiple cooling and heating cycles.
Monitor refrigerant pressures and electrical draws under load to guarantee lasting reliability.

Refrigerant Repair & Recharge: Seal leaks, evacuate old refrigerant, and replenish to factory-specified charge.
Fan Motor Replacement: Swap out worn blower motors or outdoor-unit fan assemblies to restore quiet, balanced airflow.
Compressor Service: Repair or replace compressors showing locked rotor, insufficient torque or excessive amperage draw.
Electrical Component Repair: Replace faulty capacitors, contactors, fan relays, or defrost sensors.
Control Board & Thermostat Troubleshooting: Update firmware, replace defective PCBs or recalibrate remote-unit pairings.
Condensate & Drain Line Clearing: Clear blockages from gravity or pump-fed drain lines, install float switches if needed.

Sureway Heating Cooling Plumbing believes in honest pricing rather than hidden markups. Before any repair begins, you’ll receive:

A written estimate outlining parts, labor hours and projected time on site.
Explanations of how age, refrigerant type or model rarity can influence component costs.
Financing guidance through Goodleap and FSNB for eligible homeowners facing larger-scale repairs.

While certain fixes require licensed technicians, you can perform basic checks:

Filter Inspection: Remove, clean or replace air filters every one to three months to promote airflow.
Error Code Reset: Power-cycle the unit at the breaker for five minutes; if codes persist, note them for our tech.
Remote Control Batteries: Swap batteries quarterly and confirm clear line-of-sight communication.

If your steps don’t restore normal operation, professional diagnostics will pinpoint underlying issues.

Annual tune-ups help you avoid unexpected breakdowns and maintain peak efficiency:

Coil Cleaning: Indoor-unit evaporator coils and outdoor condensers cleared of dust and debris.
Refrigerant Level Check: Early detection of slow leaks prevents performance loss and environmental impact.
Belt & Bearing Inspection: Lubricate and adjust blower assemblies to eliminate noise and wear.
Safety Device Testing: Verify float switches, high-pressure cutouts and defrost sensors operate reliably.
