Heat quit? We’ll fire it back up.

Texas winters hit quick and hard. When the furnace or heat pump goes down we find the real problem — ignitor, blower, board or refrigerant — and get the heat back on before the kids get home.

On this call · 6 checks, every visit

Same box, opposite job.

A furnace burns fuel a few feet from the air you breathe. Every heating call is a safety inspection first, a comfort call second.

You get the readings either way
Heat exchanger
01
✓Heat exchanger

Inspected for cracks. A cracked exchanger is a shutdown, not a maybe.

Combustion & flue
02
✓Combustion & flue

Flame pattern, flame sensor, ignitor, gas pressure, draft.

CO at the registers
03
✓CO at the registers

Measured, not assumed, on every gas call.

Heat pump defrost & aux
04
✓Heat pump defrost & aux

Reversing valve, defrost board, strip heat. Aux always on is quietly doubling the bill.

Blower & filter
05
✓Blower & filter

Airflow starved by a dirty filter trips the limit and looks like a “furnace problem.”

Thermostat changeover
06
✓Thermostat changeover

Heat-pump / aux settings and lockouts on the control itself.

Symptom → cause → fix

What it usually is, and what we do about it.

The common patterns we see across Bexar County. Yours gets diagnosed with gauges, not this table — but it tells you what to expect.

Tell us your symptom
SymptomUsual causeOur fix
Blowing cool on heat Heat pump defrost, or ignitor fail Normal minutes / replace ignitor
Lights, then shuts off Dirty flame sensor or high limit Clean sensor, check airflow
Bang at ignition Delayed ignition, dirty burners Clean and adjust gas pressure
Aux heat always on Control fault or changeover setting Reconfigure, test reversing valve
Burning smell first cold night Dust on exchanger — or wiring Fine if it clears; call if not
CO alarm Cracked exchanger or venting Leave, call. Shutdown and replace
02 / Symptoms

When the heat needs looking at.

Texas heating seasons are short, which is exactly why problems go unnoticed until the first hard freeze — the night everyone in the county calls at once.

Attic furnace
A furnace burner compartment doing its job — clean blue flame, no soot, no rollout. The gas safety check on every heating call starts here.

03 / Safety first

Gas heat is a safety inspection too.

A furnace burns fuel a few feet from the air your family breathes. Anything we find on the safety side gets shown to you, in plain language, before we talk about comfort.

01
Heat exchangerInspected for cracks. A cracked exchanger is a shutdown-and-replace, not a maybe — no exceptions and no upsell.
02
Combustion & ventingFlame pattern, flame sensor, ignitor, gas pressure and flue draw. Bad combustion shows up as soot and short cycling long before anything else.
03
Heat pumpsReversing valve, defrost board and auxiliary strips. When aux heat runs constantly it is usually a control fault — and it is quietly doubling your bill.

05 / Frequently asked

Heating questions, answered straight.

More of them, with numbers, on the questions page →

Why does my heat pump blow cool air sometimes?+

It is defrosting. The outdoor coil ices in cold damp weather and the system briefly reverses to clear it. A few minutes is normal; a permanent draft is not.

What is auxiliary or emergency heat costing me?+

Electric strips use several times the power of the heat pump itself. They are meant to assist in a cold snap, not run daily — if yours is always on, something is wrong.

Should I be worried about carbon monoxide?+

Take it seriously. If a CO alarm sounds, leave and call from outside. A gas furnace tune-up should include the heat exchanger, combustion and venting.

How often should heating be serviced?+

Once a year, before the first cold snap. Most no-heat calls in January trace back to something a fall visit would have caught.

Do you service gas furnaces and heat pumps both?+

Yes — gas, electric, straight-cool with strips, and dual-fuel, from every major brand.
