No obligationA furnace that won't heat is stressful, even in a mild winter. Take a breath. Most furnace problems start small, like a worn igniter, a clogged filter or a tired blower. They grow when the system keeps struggling. Checking early often keeps a small fix from turning into a bigger one.
Reasonabledependent Heating & Air is a referral service. It does not do the work. It connects you with independent providers in our network who handle heating and cooling in the Pasadena area. Older homes get special care here, because aging ductwork, past repairs and tucked-away furnaces can hide surprises. This page walks you through safety, simple checks, what a visit looks like and when replacing makes more sense than repairing.
Smell Gas? Step Outside First
Take a breath. If you smell rotten eggs or hear a hiss near the furnace, leave the house with everyone, pets included. Don't flip switches. Don't light anything. Once you're outside, phone your gas utility or emergency services. A repair provider can come after the home has been cleared.
Carbon Monoxide Has No Smell
A damaged gas furnace can release carbon monoxide, and you won't notice it. Headaches, dizziness or a sounding alarm mean you should get into fresh air and call emergency services. Many older houses have no detector at all. Put one near each sleeping area.
The First Hours Without Heat
In the first hour or two, your home still holds warmth, so you have time to think. By the evening, rooms drop a few degrees at a time. Close doors, pull curtains and gather blankets. Mild winters here make this easier, but a rare hard freeze changes the picture.
Day Two and Beyond
After a full day, cold gets into walls and floors. Pier-and-beam houses can lose heat fast through the floor, and exposed pipes underneath may be at risk during a freeze. Small now, bigger later. That is why it helps to reach a provider before the cold deepens.
Quick Checks Before You Reach Out
A few simple checks can save a visit. They take five minutes.
- Make sure the thermostat is set to heat and the batteries are fresh.
- Check that the breaker and the furnace switch are on.
- Look at the filter. If it's gray and packed, replace it.
- Make sure the vents and returns aren't blocked by furniture.
If none of that helps, stop there. Don't open panels or reset the unit again and again.
Signs Your Furnace Is Asking for Help
Furnaces usually give hints before they quit.
- Banging, squealing or rattling when it starts
- Weak airflow or air that never gets warm
- Short bursts that start and stop often
- A yellow or flickering burner flame
- Higher energy bills with no change in habits
Any one of these is worth a look.
Why Old Houses Need Extra Patience
Old houses remember. Past owners may have patched ducts, added rooms or swapped parts with whatever fit. A furnace in such a home may be working harder than anyone knows. A careful provider looks at the whole path of air, not just the machine.
Ductwork, Vents and Past Repairs
Older ducts can leak, crush or come loose. Warm air then escapes into a crawl space or attic before it reaches your rooms. Ask the provider to check for loose seams and old tape. Mention any past repairs you know about. That history helps.
Tucked-Away Furnaces and Hot Attics
Many local homes are slab-on-grade ranches with the furnace in a closet or the attic. Attics here get very hot in summer, which can wear on wiring, sensors and the condensate line. A furnace that sat idle all season may fail on its first cold night.
What a Repair Visit Looks Like
A provider usually starts by asking what you've seen and heard. Then they check the thermostat, the filter, the burner, the igniter and the blower. They test safety controls and look for gas or exhaust trouble. Next, they explain what they found and give a written quote before starting the repair.
Common Furnace Repairs
- Replacing a cracked or worn igniter
- Cleaning or replacing a flame sensor
- Fixing a blower motor or capacitor
- Repairing a draft inducer or control board
- Swapping a failing thermostat
Most of these are routine for a trained provider.
Repair or Replace Your Furnace?
A furnace past 15 to 20 years old, with repeated breakdowns, may be near the end. A cracked heat exchanger is another serious sign. If repair costs climb close to half the price of a new unit, replacement deserves a look. Ask for both options in writing, and search for furnace replacement near me only after you've compared the numbers.
Questions Worth Asking the Provider
- What exactly failed, and can you show me?
- Is this a repair that will last, or a patch?
- Will you check the ducts and the vent pipe?
- What does the written quote include?
- What happens if the same problem returns?
Keeping Your Paperwork in Order
Save your quote, invoice and any photos. Some policies may cover sudden damage, so check yours. Providers can often help document damage for a claim.
Take the Next Small Step
You don't need to solve everything tonight. Stay safe, stay warm and make one simple move. Request a callback to check provider availability, or send a request and let a local provider reach out.
What's Included
Safety Check
A provider checks the burner, vent and gas connections so you know the furnace runs safely.
Clear Diagnosis
You get a plain explanation of what failed and why, before any work begins.
Written Quote
Ask for the repair price on paper so there are no surprises later.
Older-Home Care
Providers can look at aging ducts, past patches and tucked-away equipment that older houses often hide.
Typical Furnace Repair Costs
Prices vary by home, part and furnace age. These are typical U.S. ranges, not quotes. Always ask the provider for a written estimate that lists parts and labor before work starts.
| Repair item | Typical range | Notes |
|---|---|---|
| Diagnostic visit | $75 – $200 | Often applied toward the repair |
| Igniter replacement | $100 – $350 | Common cause of no-heat calls |
| Flame sensor | $100 – $300 | Cleaning costs less than replacing |
| Blower motor | $400 – $1,500 | Varies by motor type |
| Control board or inducer | $300 – $900 | Parts availability affects price |
| Heat exchanger repair | $1,500 – $3,500 | Often leads to a replace-or-repair talk |

FAQ
Furnace Repair FAQ
Why is my furnace running but not blowing warm air?
Common causes include a dirty filter, a failed igniter, a faulty flame sensor or a thermostat issue. Check the filter and thermostat first. If air stays cool, a local provider can diagnose the cause safely.
How long can I stay in a house with no heat?
In mild weather, many homes stay tolerable for a day or so. In a freeze, cold sets in faster and pipes may be at risk. Use blankets and get help soon.
Is it worth repairing an old furnace?
Often yes, if the problem is small and the unit is under about 15 years old. If repairs are frequent or costly, ask a provider to quote replacement too.
