Corpus Christi HVAC Q&A: Pricing, Permits & Timing

When is a furnace problem an actual emergency vs. a next-day call?

Carbon-monoxide alarm, smell of gas, or visible cracks in the heat exchanger → emergency. No-heat in sub-freezing weather is urgent but rarely safety-critical. Most no-heat calls are igniter, flame sensor, or gas valve — same-day fixable.

What's the difference between a flame-sensor clean ($120) and heat-exchanger replacement ($1,500+)?

Flame sensors clog with combustion residue and stop signaling the gas valve — quick clean or swap. Cracked heat exchangers leak CO into your home airflow and require exchanger replacement (often impractical) or full furnace replacement. The tech's CO meter reading decides which one you're facing.

Do Corpus Christi HVAC contractors require specific permits for system replacements?

Yes, most HVAC replacements in Corpus Christi require a mechanical permit issued by the city’s Development Services Department. This ensures that new installations meet current building codes and safety standards. Licensed contractors typically handle the permit application and inspection scheduling process for homeowners to ensure full compliance with municipal regulations.
