A furnace that blows cold air, makes odd noises, or will not start can feel stressful. Some problems are small. Others involve gas, electricity, or exhaust, and those need care. Extentway Heating & Air helps you take safe first steps, then connects you with independent providers in our network who do the actual repair work.
In the Delray Beach area, many furnaces sit unused for months and then get asked to work during a sudden cold snap. Dust, worn parts, and damp air can show up at the worst time. Timing changes outcomes, so a small fault caught early is often simpler to fix. This page explains what to do, what not to do, and what to expect from a visit. Extentway Heating & Air does not do the work itself.
Smell Gas? Stop and Step Outside
A rotten-egg smell or a hissing sound near the furnace is serious. Act on it before anything else.
- Do leave the home with everyone, pets included.
- Do call 911 or your gas utility from outside.
- Do not flip light switches, use a lighter, or start a car in an attached garage.
- Do not go back in until you are told it is safe.
A repair provider can help only after the gas has been cleared.
Carbon Monoxide Alarm Going Off
Headache, dizziness, and nausea can point to carbon monoxide. If an alarm sounds, get everyone outside and call 911. Do not silence it and carry on. Do not run the furnace again until a provider has checked it.
Why Timing Changes the Outcome
Furnace faults rarely stay still. Here is how a typical problem can grow.
The First Hour
You notice weak heat, a clicking sound, or a burning smell. This is the right moment to stop, note what you see, and shut the system off if anything seems unsafe.
The First Day
A furnace that keeps trying to start can strain parts like the igniter and blower. The house cools, and damp indoor air can settle on cold surfaces.
After a Few Days
Small faults can turn into larger repairs. Pipes in cold areas, tired family members, and rushed choices add pressure. Stop, note what you see, and request help. That simple routine keeps you ahead of it.
Quick Checks Before You Request Help
These are safe and take a few minutes.
- Make sure the thermostat is set to heat and the temperature is above the room reading.
- Replace dead thermostat batteries.
- Check that the furnace switch near the unit is on.
- Look at the air filter. A very clogged one can shut a furnace down.
- Check your breaker panel for a tripped breaker.
What Not to Do
- Do not open the burner or gas compartment.
- Do not reset a tripped breaker again and again.
- Do not block vents or the area around the furnace.
- Do not use an oven or grill to heat the home.
- Do not try to bypass safety switches.
Common Signs Your Furnace Needs Repair
Watch for these clues:
- Cold air from the vents, or no air at all
- Banging, squealing, or rattling
- A flame that is yellow or flickers
- Short cycling, where it starts and stops often
- Higher bills with no change in use
- A burning smell that does not fade
If you notice more than one, mention all of them to the provider.
Document Before Repairs
A few minutes of record keeping makes estimates clearer. Take photos of the furnace, the thermostat display, and any error code light. Write down when the trouble began and what you heard or smelled. Save old repair papers and the unit's model label. If a policy question comes up, providers can often help document damage for a claim, and some policies may cover sudden damage, so check your policy.
What Happens During a Furnace Repair Visit
The provider usually starts with questions about the symptoms. Next comes a look at the thermostat, filter, burners, and airflow. They test safety controls and check for gas or exhaust issues. You should get a clear explanation and a written quote before any larger repair begins. Ask to see worn parts if you wish.
Common Furnace Repairs
Many fixes are small parts:
- Igniter or flame sensor cleaning or replacement
- Blower motor or capacitor
- Inducer motor and pressure switch
- Control board
- Thermostat wiring or replacement
- Condensate drain clearing on high-efficiency units
A cracked heat exchanger is more serious and usually means the unit should not run.
Humid Climate Notes for Your Area
Milder winters mean furnaces and heat strips often rest for months. Humid air, dust, and storm season power surges can wear on boards and motors. If a storm caused an outage, ask the provider to check the controls. In homes with the unit in a closet or attic, clear the space of stored items.
Repair or Replace Your Furnace?
A repair often makes sense when the unit is fairly young and the fault is one part. Replacement may be worth discussing when the furnace is old, needs repeated repairs, or has a cracked heat exchanger. Many people search furnace replacement near me when a quote feels close to the price of a new unit. Ask for both numbers in writing. Also tell the provider about your heating and cooling needs, since one HVAC service visit can look at the whole system.
Questions to Ask the Provider
- What is the likely cause, and how sure are you?
- Is the repair safe to run until the part arrives?
- What is the full written quote, parts and labor?
- How long is the repair warranty on parts and work?
- Would you test for carbon monoxide after?
Cooling Trouble Too?
If your air conditioner also fails, make a separate request. Emergency AC repair has its own steps and its own page.

Why is my furnace running but not heating the house?
Common causes include a dirty filter, a bad thermostat setting, a failed igniter, or a blower problem. Try the safe quick checks first. If heat is still weak, ask a local provider to inspect it.
Is it safe to keep using a furnace that smells like burning?
A brief dusty smell can happen after long idle months. A strong or lasting burning smell is different. Turn the unit off and ask a provider to inspect it.
Should I repair or replace an old furnace?
It depends on age, repair cost, and safety. Ask for repair and replacement quotes in writing, then compare them. A provider can explain which option fits your home.
