HVAC System Repair Glenview IL

HVAC System Repair in Glenview, IL

Something’s wrong. You’re not sure what. The system runs but the house isn’t getting comfortable, or it stopped running entirely, or it’s making a sound you’ve never heard before. You need someone to figure out the actual problem — not swap parts until something works — and fix it.

Top Air Solutions has been diagnosing and repairing HVAC systems in Glenview for 17 years. We work on the full system: cooling, heating, controls, electrical, refrigerant. Not just one side.

Cooling System Repairs

• Refrigerant leaks — finding and fixing the source, then recharging correctly
• Compressor failures — diagnosis first, replacement when it’s warranted
• Condenser and evaporator coil issues — cleaning, repair, or replacement
• Fan motor failures on indoor and outdoor units
• Frozen evaporator coils — fixing the root cause, not just defrosting
• Electrical component failures throughout the system

Heating System Repairs

For furnace-specific failures — igniter problems, heat exchanger issues, blower motor repairs — our furnace and heater repair page covers those in detail. This page focuses on full system issues that cross both heating and cooling, and on the broader electrical and control systems.

Controls and Electrical

• Thermostat malfunctions and communication failures between thermostat and equipment
• Control board failures
• Zone control system problems
• Wiring issues — loose connections, corrosion, errors from previous service
• Capacitor and contactor failures — among the most common AC component failures
• Sensor and limit switch problems

We Diagnose Before We Recommend

HVAC problems get misdiagnosed regularly. A system blowing warm air instead of cold could be a refrigerant leak, a failed compressor, a dirty coil, a bad capacitor, or a wiring problem. Those aren’t the same issue. They have different causes, different costs, and different fixes.

We check the full system before telling you what’s wrong. Written estimate before any repair starts. If what we find during the diagnostic changes the scope, you hear about it before we proceed — not after.

Brands We Service

Lennox we know best — we’re an authorized dealer. But we repair Carrier, Trane, Goodman, Rheem, York, American Standard, and others. If someone else installed it, we can still diagnose and fix it.

Repair or Replace?

Not every service call ends in a replacement recommendation. A single failed component on an otherwise healthy system — replace the part. But a 15-year-old system facing a major repair is a different conversation. Putting significant money into old, inefficient equipment often doesn’t make sense when you look at what it costs to run month to month.

We’ll give you the honest math on both options. The goal is a decision that’s right for your situation, not the one that generates the bigger invoice.
