Serving the Greater Chicagoland AreaWe service what other
We service what other
HVAC companieswon't.
Many HVAC companies have been purchased by private equity that value profits above customer service. They send a salesperson to your home to sell you a replacement unit rather than a service technician to fix the problem. At TigZ HVAC, our goal is to fix what you already own. We are an owner-operated, diagnostic-first heating and cooling repair company with customer-friendly, transparent pricing.

HVAC Diagnostics & repair —
not a sales pitch.
We specialize in finding the problem and fixing it. Unlike most of our competition, there's no pressure to replace a system that still has years of service life.
Diagnose & repair
Diagnose & repairBlower Motor & Ignition Fixes
Are you experiencing weak airflow, rattling, or a failed ignition sequence? We can repair blower motors, control boards, safeties, and ignition components.

Seasonal Tune-Ups and Cleanings
A pre-season tune-up and cleaning could mean a smaller repair now instead of an emergency call in the warmest or coldest seasonal months throughout the year.
Diagnose & repairNew Furnace, Air Conditioner, and Heat Pump Installation
It's our priority to repair your existing unit first. But if that's not possible, we'll say so plainly and quote a replacement unit fairly with no commission and no manufactured urgency.
Diagnose & repairAC Refrigerant Charging & Compressor Diagnostics
Are you experiencing warm air, frozen lines, or spiking energy bills? We'll diagnose the cause, whether it's poor airflow or refrigerant loss requiring separate leak detection.

The TigZ difference
We don't work on commission.
Instead we get paid to solve problems. Plenty of HVAC companies make their money nowadays by convincing you to purchase a new system you probably don't need. That's NOT the way it should be and is why we exist.
You get a diagnosis, not a sales pitch
Accurate diagnosis. Honest explanations. No pressure. You decide the best way forward.
Fair and honest pricing
Clear pricing from the start. You approve the flat rate first so there are never hidden fees on your invoice.
Repair first, always
If it can be fixed properly and safely, we'll fix it. Replacement is the last option, not the first offer.
One point of contact
The owner does the work personally. No call centers, no revolving door of technicians, and zero runaround.

A decade of field experience, backed by a
person who answers the phone.
Tyler spent ten years repairing heating and cooling systems for other people's companies. Along the way he built something you can't buy: a list of customers who asked for him by name, every single time.
TigZ HVAC is what happens when a technician decides the customer deserves the truth. No quotas, no scripted pitch, no pressure to purchase a system you don't need. Just careful diagnostic work, a fair price, and a repair that lasts. Good old fashioned customer service.
