What it is
Heating repair is the work of finding out why a heating system is not keeping your home comfortable and correcting the problem. It usually involves a furnace, heat pump, boiler or other heater, along with the thermostat, ductwork and controls that go with it.
Common topics include furnace repair, a heater that will not turn on, a furnace blowing cold air, thermostat and ignition problems, and blower and airflow problems. Each symptom can have several possible causes, which is why a careful diagnosis matters.
Many heating systems involve gas, electricity or both. That means some work is safe for a homeowner to check, while much of it belongs with a licensed, qualified professional.
How it’s traditionally been approached
Traditionally, a heating repair starts with the symptom. A technician listens to what you have noticed, such as odd noises, short cycling, uneven rooms or no heat at all, and then inspects the system step by step.
Typical areas to look at include thermostat settings and wiring, the ignition or heat source, the blower motor and fan, air filters, vents and ductwork. Airflow restrictions and control issues are often part of the picture.
Some homeowners choose repair, while others weigh replacement when a system is older or repairs keep recurring. Both approaches are common, and the right fit depends on your home, your system and your budget.
How the right HVAC pro may help
The right HVAC pro may help by identifying the cause rather than guessing. A visit generally begins with questions about what you have noticed and when it started, followed by an inspection of the system and an explanation of what was found.
Before work begins, it can help to ask for a written quote that explains the problem, the proposed repair, the parts involved and any warranty on parts or labor. You can also ask whether other options exist and what happens if you wait.
It is reasonable to ask about licensing and insurance, and to verify them with your state or local licensing board. Requirements for licenses, permits and codes vary by location, and refrigerant work requires proper EPA certification in general.
The bigger picture
A heater that stops working can bring real stress, especially in cold weather or when children, older relatives or anyone with health needs are at home. Worry about cost and about choosing the right person is common, and it is okay to take a calm, step-by-step approach.

Keep in mind
- If you smell gas or a carbon monoxide alarm sounds, leave the home immediately and call your gas utility's emergency line or 911 from outside.
- Safe homeowner checks include confirming thermostat settings, looking at the air filter, checking for a breaker that has already tripped and making sure vents are not blocked.
- Do not attempt DIY work on gas lines, burners, gas valves, pilot assemblies, electrical panels, capacitors, wiring or refrigerant. Leave those to qualified professionals.
- Costs vary with the problem, the parts and your location, so get written quotes and compare them before deciding.

Frequently asked questions
Why is my furnace blowing cold air?
A furnace may blow cold air for several reasons, including thermostat settings, a restricted air filter, an ignition or heat source issue, or a control problem. You can safely check that the thermostat is set to heat and the fan is not on a setting that only circulates air, and look at the filter. If it continues, a qualified HVAC pro can diagnose the cause.
What should I do when my heater is not working?
Start with simple safe checks: confirm the thermostat is set to heat and a comfortable temperature, check the air filter, and look for a breaker that has already tripped. If nothing changes, contact a licensed HVAC pro. If you smell gas or a carbon monoxide alarm sounds, leave the home and call the gas utility or 911 from outside.
Why won't my house warm up even though the heater is running?
Possible causes include restricted airflow, a dirty filter, blocked vents, ductwork problems, a blower issue or a system that is struggling to keep up. Home insulation and drafts can also play a role. A professional visit can help narrow down which factors apply to your home.
Is air conditioning repair different from heating repair?
Air conditioning repair and heating repair are related but usually focus on different components. Many homes share the thermostat, blower and ductwork between both, so a problem in one area may affect the other. Many HVAC pros handle both, so it can help to ask about their experience with your system type.
How do I choose a heating repair professional?
Check the contractor's license and insurance with your state or local licensing board, and ask for a written quote that describes the work. You may also read reviews and ask about warranties and how they handle diagnosis. Requirements vary by location, so verify locally.
How much does heating repair cost?
Cost depends on the problem, the parts needed, the type of system, how easy it is to access and local labor rates. This page cannot quote prices. Getting written quotes from more than one qualified provider is a practical way to compare.
