How Heating Repair Works in Corpus Christi
What to expect from a licensed Corpus Christi HVAC contractor from first call to completion.
- 1
Safety Check First (CO test, gas leak sniff)
Before diagnosing performance issues, the technician tests for CO presence and checks gas connections for leaks. Safety issues are addressed before any other repair work begins.
- 2
Diagnostic Scan
Control board fault codes are read, and key components — ignitor, flame sensor, pressure switches, inducer motor, and heat exchanger — are inspected and tested.
- 3
Repair & Parts Replacement
Failed components are replaced with OEM or compatible parts. Gas valve, ignitor, and circuit board replacements are common; all are tested after installation.
- 4
Combustion Test
After repairs, combustion efficiency is verified: burner flame color, CO output, and flue gas temperature confirm safe and efficient operation.
- 5
Full Heating Cycle Test
System is run through a complete heating cycle. Temperature rise across the heat exchanger is measured to confirm the unit is operating within manufacturer specs.
Frequently Asked Questions About Heating Repair in Corpus Christi, TX
What should I check before calling an HVAC technician for a heating problem?
Before calling a pro, verify your thermostat is set to Heat mode (not Cool) and the temperature is above room temperature; check that your air filter isn't completely clogged (restricts airflow and can trigger safety shutoff); confirm the furnace switch and breaker are on; and check that your gas supply valve is open. If the pilot light is out on an older unit, follow the relighting instructions on the furnace door. If you smell gas, leave the home immediately and call your gas utility.
Why is my heat pump blowing cold air in heating mode?
Heat pumps blow air that feels cooler than gas furnace output — typically 90–100°F versus 130°F from a gas furnace. If the air is room temperature or below, the unit may be stuck in defrost mode (normal, lasts 5–15 minutes), have a refrigerant leak, a faulty reversing valve, or a bad defrost control board. A licensed technician can diagnose the issue within one visit.
How long does a furnace last?
Gas furnaces typically last 15–20 years with regular maintenance. Heat pumps last 12–15 years. Electric furnaces can last 20–30 years. Regular annual maintenance (filter changes, burner cleaning, heat exchanger inspection) keeps systems at the high end of these ranges. If your furnace is over 15 years old and needs a major repair, replacement is often the better investment.
