Furnace Repair
When a furnace stops heating, blows cold air, short cycles or develops a new noise or odor, the first job is to identify the actual failure not guess which part to replace. Hana Hou’s furnace repair service is the furnace-specific repair authority for Orange County, while the broader heating repair page covers mixed heating-system problems and furnace maintenance and tune-ups covers preventive service. If replacement becomes the better option, the correct next step is furnace installation.
Furnace repair should begin with the symptom and the operating sequence: thermostat call, power, ignition, combustion, safeties, blower operation and airflow. The goal is to determine why the furnace failed and whether the repair is safe and reasonable. Gas or carbon-monoxide emergencies require immediate emergency response rather than a routine appointment. Once the hazard is addressed, Hana Hou can evaluate the equipment through furnace repair, compare furnace installation if needed and plan future furnace maintenance and tune-ups.
Every furnace repair call starts with a full diagnostic, not a guess based on the symptom you described on the phone, because “no heat” can mean a $150 flame sensor cleaning or a $600 igniter depending on what we actually find. We’ll show you the failed part, explain what caused it, and give you a firm price before starting any work. Most in-warranty repairs are same-day; parts we don’t stock, usually older or less common control boards, typically take 1-2 days to source before we’re back on site to finish the job.
Signs Your Furnace Needs a Repair Call
Call us if you’re seeing any of these, waiting usually makes the fix more expensive.
- The furnace won’t ignite, or it lights and then shuts right back off
- You’re hearing banging, screeching, or a loud clicking that wasn’t there before
- The blower runs constantly but the air coming out isn’t warm
- Your thermostat is set correctly but rooms still feel cold
- The furnace short-cycles, turning on and off every few minutes
- You smell gas, notice soot near the vents, or the carbon monoxide alarm goes off
That last one is an emergency: shut off the gas at the furnace and call us right away, don’t wait for a scheduled visit.
A furnace that’s failed once will fail again if we only chase the symptom instead of the root cause, which is why we check gas pressure, blower amperage, and heat exchanger condition on every repair call, not just the part that finally quit. If your furnace is past 15 years old and starting to nickel-and-dime you with repair visits, it’s worth pricing a furnace installation alongside the repair quote so you’re deciding with real numbers in front of you. See what our repair customers say on our reviews page.

Frequently Asked Questions
Why is my furnace blowing cold air instead of heat?
This is almost always ignition failure, either the gas valve isn’t opening, the igniter isn’t heating up, or the flame sensor is too dirty to detect a flame and the system shuts the gas back off as a safety measure. The blower keeps running because it’s on its own control cycle. See a real diagnostic walkthrough on our Costa Mesa furnace repair page.
How much does furnace repair cost in Orange County?
Simple fixes like a flame sensor cleaning or capacitor swap often run under $250, while a control board or gas valve replacement can run several hundred more depending on the brand. We break down real numbers on our furnace repair cost guide, but every job gets a firm quote before we start.
Is it worth repairing an old furnace or should I replace it?
If the furnace is under 12 years old and the repair is under a few hundred dollars, repair almost always makes sense. Past 15 years, or if you’re facing a cracked heat exchanger, it’s usually smarter to put that money toward a new furnace installation. We’ll give you a straight recommendation either way, not just the option that costs more.
How quickly can you come out for a furnace repair?
We offer same-day service for no-heat calls in most of our Orange County and Temecula service area, and we carry the parts for major brands so most repairs finish in one visit. Request service through our contact page and we’ll get you the earliest available slot.
What does it mean if my furnace keeps turning on and off?
Short-cycling is usually caused by a clogged filter restricting airflow, an overheating limit switch, or a furnace that was oversized for the home to begin with. A dirty filter is the cheapest fix and the one we check first. If yours cycles often, our furnace maintenance plan catches airflow problems before they force an emergency call.
Why does my furnace smell like gas or burning?
A brief burning smell in the first few minutes of the heating season is often just dust burning off the heat exchanger and usually clears on its own, but a persistent gas odor means a leak and you should shut off the gas at the furnace and call us immediately. This is not a wait-for-an-appointment situation.
What are common furnace error codes and what do they mean?
Most modern furnaces flash an LED code on the control board that maps to a specific fault, a certain number of blinks for ignition failure, another pattern for a pressure switch issue, and so on, and the sequence varies by brand. Note the blink pattern before you call so we can come prepared with the likely part already on the truck.
Do you repair Goodman and Lennox furnaces?
Yes, we service Carrier, Trane, Lennox, and Goodman furnaces and stock common parts for all four brands, along with most other major manufacturers installed across Southern California. See how our repairs have held up on our reviews page.
Can a furnace repair wait, or is it always urgent?
A furnace that’s heating unevenly or making unusual noise can typically wait a few days for a scheduled visit. A complete no-heat situation, a gas smell, or a carbon monoxide alarm should never wait, those are same-day calls. If you’re unsure which category you’re in, call us and describe what you’re seeing; we’ll tell you honestly.
How do I book a furnace repair appointment?
Call us or request service through our contact page, describe what the furnace is doing, and we’ll get a technician out, often same-day for no-heat calls. Check our current coupons before you book, and ask about our ‘Ohana Membership for priority scheduling on future calls.
