Heating System Repair in Houston, TX — Call Multipoint AC & Heating When Your Heat Goes Out

Your heating system worked fine last winter. You haven’t touched it since February. A cold front pushed through Houston overnight — temperatures dropped from 78 to 48 in a matter of hours — and this morning the thermostat is calling for heat and nothing is happening. Or something is happening and then stopping after a few seconds. Or warm air never comes from the vents.

You need heating system repair in Houston, you need it today, and you need a company that will show up, find the problem, and fix it — not one that keeps you waiting until tomorrow or tells you the system needs replacing before they’ve properly diagnosed what’s actually wrong.

WHY HEATING SYSTEM FAILURES PEAK IN HOUSTON RIGHT NOW — OCTOBER AND NOVEMBER

If you’re searching for heating system repair in Houston today, you’re part of a predictable October and November pattern that repeats every year across the Greater Houston metro. Understanding why it happens helps you understand what’s likely wrong with your specific system.

Heating system repair searches show a +594% variance between October highs and January lows — making it the most weather-sensitive HVAC search term. That spike happens because Houston heating systems spend seven to eight months completely idle while the AC runs through the long cooling season. During those months of dormancy in Houston’s high-humidity environment, specific components deteriorate in ways that only reveal themselves when the system is first called on for heat. abc17news

The flame sensor is the single most common cause of first-cold-front heating failures in Houston. This thin metal rod is positioned in the furnace burner flame and sends a signal to the control board confirming the flame is present. During seven months of idle in Houston’s humidity, oxidation accumulates on the sensor surface. When the furnace tries to light in October, the control board opens the gas valve, the ignitor fires, the burner briefly lights — but the oxidized sensor can’t generate a clean signal. The control board interprets this as a failed ignition, shuts the gas off as a safety measure, and tries again. Two or three failed attempts and the furnace goes into lockout. The house doesn’t heat.

This is a $100 to $250 repair. It’s also the reason a fall heating inspection in September — which Multipoint’s maintenance plan customers receive every year — prevents the October emergency call. But if the inspection didn’t happen and the system failed this morning, the repair is still straightforward when the right technician shows up and diagnoses correctly.

The ignitor is the second most common cause. Electronic ignitors have a defined service life and age past their functional threshold during the idle period as well as during active operation. A failed ignitor prevents the furnace from attempting to light at all — no ignition sequence, no flame, no heat. A degraded ignitor may light intermittently, producing a furnace that works sometimes and not others. Ignitor replacement runs $150 to $350.

Control board failures produce a range of symptoms from complete non-response to specific functions failing while others work. The control board connections that were functioning in February have had seven months of Houston’s humidity to develop corrosion that affects electrical contact quality. Control board replacement runs $400 to $900 depending on the furnace brand and model.

Draft inducer motor failures prevent the furnace from starting even when all other components are functional. The inducer has to start before the gas valve can open — the control sequence requires it — and a failing inducer motor produces a symptom where nothing happens when the thermostat calls for heat, or the inducer starts briefly and stops before ignition is attempted. Draft inducer motor replacement runs $350 to $700.

WHAT TO CHECK YOURSELF BEFORE CALLING

A meaningful number of Houston heating failures have causes that homeowners can address themselves in five to ten minutes. Work through these before calling for service — if any of them resolves the problem, you’ve saved yourself a service call.

Check the thermostat mode and setpoint. The thermostat must be in HEAT mode — not COOL, not FAN ONLY — and the setpoint must be above the current indoor temperature. A thermostat accidentally left in cooling mode from the summer produces the symptom of no heating response without any equipment failure. Check the batteries too — a thermostat with dead batteries goes blank or unresponsive and prevents any system operation regardless of mode.

Check the circuit breaker. The air handler or furnace has a dedicated circuit breaker in the main electrical panel. A tripped breaker sits in a middle position between fully on and fully off. Reset it by switching firmly to off and then back to on. If it trips again immediately, stop resetting it — a repeatedly tripping breaker indicates an electrical fault that needs professional diagnosis.

Find the furnace power switch. Most furnaces have a dedicated power switch on or near the unit that looks exactly like a standard light switch. If it was accidentally switched off during the summer, turning it back on restores power immediately.

Check the filter. A severely clogged filter causes the furnace to overheat and trip the high-limit safety switch, which shuts the system off after a few minutes of operation. Replace a loaded filter and allow the system to cool for 20 to 30 minutes before restarting.

Check the access panel. Most furnaces have a safety switch on the access panel that prevents operation when the panel is open or improperly seated. Press it firmly closed and verify it’s properly latched.

If none of these resolve it, the problem requires professional diagnosis. Call Multipoint AC & Heating at 832-963-3789.

WHAT MULTIPOINT DOES DIFFERENTLY FOR HEATING SYSTEM REPAIR IN HOUSTON

Heating system repair in October and November in Houston is a seller’s market. Every HVAC company in the metro is fielding calls simultaneously, emergency rates apply after hours, and homeowners who are cold and stressed are not in the ideal position for careful company evaluation. This is exactly the market dynamic that some HVAC companies exploit — recommending unnecessary replacements, charging premium rates for straightforward repairs, or performing incomplete diagnostics that miss the actual cause.

Multipoint AC & Heating operates differently. Here’s specifically what that means for a Houston homeowner calling for heating system repair today.

We diagnose before we recommend. A Multipoint technician arriving at a Houston home for a heating failure evaluates the flame sensor, tests the ignitor against its specification, checks the control board connections and operation, verifies gas pressure and burner operation, assesses the draft inducer, and tests safety controls — before recommending any repair. The recommendation comes from what we find, every time. We don’t walk in assuming the system needs replacement and work backward from there.

We show you what we found. If the flame sensor is oxidized, we show it to you. If the ignitor is reading below its rated output, we show you the measurement and the specification. If the heat exchanger shows a finding that concerns us, we explain specifically what we observed. You understand the basis for our recommendation before you approve any work.

We charge what we quote. The price for a repair is stated clearly before work begins. No surprises at invoice time, no additional charges that weren’t discussed first. If we find something additional during the repair that changes the scope, we tell you specifically what it is and what it costs before proceeding.

We’re honest about repair versus replacement. A furnace that needs a $150 flame sensor cleaning doesn’t need to be replaced. A furnace that’s fifteen years old with a cracked heat exchanger and a failed control board might. Multipoint tells you which is which based on what we actually find — not based on what maximizes our revenue from the call.

We answer 24/7. The call at 10pm on a Friday night when the house is cold and the kids need to be up for school in the morning gets the same response as the call at 9am on a Tuesday. Emergency heating repair service throughout Greater Houston is available from Multipoint at any hour because that’s when Houston homeowners actually need it.

THE HEATING SYSTEMS MULTIPOINT REPAIRS IN HOUSTON

Gas furnaces are the most common heating system in Greater Houston homes. Multipoint repairs gas furnaces from all major manufacturers — Trane, Carrier, Lennox, Goodman, Rheem, York, Daikin, and others. Single-stage, two-stage, and variable-speed systems. Standard efficiency and high-efficiency condensing furnaces. Whatever is in your Houston home, Multipoint has the diagnostic experience and parts access to address it.

Heat pumps handle both cooling and heating from a single system and are increasingly common in Greater Houston’s housing market — particularly in newer construction and in communities where all-electric homes were built to take advantage of heat pump efficiency. Heat pump heating failures have specific diagnostic considerations that gas furnace failures don’t — reversing valve issues, defrost system problems, heating-mode refrigerant charge verification — and Multipoint has the specific heat pump diagnostic experience these systems require. If your heat pump is blowing cold air in heating mode, running without producing warm air, or icing up on the outdoor unit, call 832-963-3789.

Electric furnaces and air handlers with electric resistance heat are less common in Houston but present in some homes, particularly older construction in certain communities. Electric heating system failures typically involve sequencers, heating elements, or limit controls — Multipoint diagnoses and repairs these systems as part of our full heating service offering.

Mini split heat pumps are growing in Houston’s market as supplemental heating and cooling solutions, particularly for additions, detached garages converted to living space, and homes where specific rooms present heating and cooling challenges that the central system doesn’t address well. Multipoint repairs and services mini split systems as part of our comprehensive HVAC service offering.

HOW MUCH DOES HEATING SYSTEM REPAIR COST IN HOUSTON IN 2026

Houston homeowners searching for heating system repair today deserve honest cost information before they call anyone. Here’s what common heating repairs actually cost from a licensed, insured Greater Houston HVAC company in October 2026.

Diagnostic service call — $75 to $150 for a standard business-hours diagnostic visit. Emergency service calls outside business hours carry a premium that varies by company but typically adds $75 to $150 to the standard diagnostic rate. At Multipoint, the diagnostic fee is applied toward any repair performed during the same visit.

Flame sensor cleaning or replacement — $100 to $250 including labor. This is the most common heating repair call in Houston’s fall season and one of the most affordable. If your furnace attempts to light and shuts off after a few seconds repeatedly, this is the most likely cause and the most straightforward repair.

Ignitor replacement — $150 to $350 depending on the ignitor type and furnace model. Silicon carbide and silicon nitride ignitors are the most common types in Houston residential furnaces and are readily available for most systems.

Thermostat replacement — $100 to $400 depending on whether a basic replacement or a smart thermostat is appropriate.

Draft inducer motor replacement — $350 to $700 including parts and labor.

Gas valve replacement — $300 to $600 including parts and labor.

Blower motor replacement — $300 to $600 depending on motor type.

Control board replacement — $400 to $900 depending on furnace brand and model.

Heat exchanger repair or replacement — $300 to $600 for repair; $1,000 to $2,000 or more for heat exchanger replacement. On systems past twelve to fifteen years old in Houston’s climate, heat exchanger replacement is typically the point where full system replacement becomes the more financially sound decision.

After-hours emergency service premium — standard across the Houston HVAC market for calls outside business hours, evenings, weekends, and holidays. Emergency rates typically add $75 to $150 to standard diagnostic and labor rates. Multipoint maintenance plan customers receive priority scheduling that reduces wait times and in some cases reduces the emergency premium relative to non-member rates.

THE HEATING SYSTEM INSPECTION THAT PREVENTS EMERGENCY CALLS

Every October heating system failure that Multipoint repairs in Houston — every flame sensor that needed cleaning, every ignitor that failed its first-use test, every control board connection that had corroded during the idle period — represents a problem that a fall heating inspection in September would have caught and addressed before the cold front made it an emergency.

Multipoint’s maintenance plan includes a fall heating inspection every September — before the first cold fronts of the season, while there’s still time to address anything found without the pressure of cold weather and a household without heat. Maintenance plan customers who had their fall inspection in September are not in the emergency call queue today. They know whether their flame sensor is clean, whether their ignitor is within specification, whether their heat exchanger passed inspection. Their systems were ready for this cold front because someone checked.

For homeowners whose system failed today and who want to make sure they’re not in this position again next October, a Multipoint maintenance plan that starts with a post-repair service assessment and includes the fall inspection every subsequent September is the mechanism that converts this emergency into the last one.

Call Multipoint AC & Heating at 832-963-3789 to discuss a maintenance plan that protects your Houston heating and cooling system year-round.
