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.

How we are different

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.

Furnace Troubleshooting & Repair

Is your furnace short cycling or refusing to fire? There's nothing worse than being without heat when it's cold. We can trace the fault to its source and fix the actual problem.

Blower 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.

New 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.

AC 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.

Heat Pump Repair Services

Modern heat pumps require a careful set of hands. We take the guesswork out of troubleshooting by resolving everything from fine-tuned refrigerant balances to electronic control issues quickly and accurately.

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.
