A heating tune-up is a once-a-year inspection, cleaning and safety check that gets your furnace or heat pump ready for the cold months. Here’s what a complete tune-up should cover on a furnace and on a heat pump, what it costs, and when to book.
Do you need a heating tune-up before winter?
Yes. First Choice Heating & Air Conditioning recommends a professional heating check every fall, before the first cold night, for both gas furnaces and heat pumps. A system that ran fine last winter has still sat idle for months, and dust, worn parts and loose electrical connections show up the first time it has to run for hours. We often find that no-heat calls in winter trace back to skipped maintenance. Common culprits, like a dirty flame sensor, a weak capacitor or a clogged filter, are all things a fall visit checks. A tune-up also checks the parts that keep your family safe, including the heat exchanger and the gas connections on a furnace. Book it before the busy season fills the schedule.
What does a heating tune-up include?
A complete heating tune-up covers the system’s electrical parts, controls and safety components, plus the checks that are specific to your equipment. Gas furnaces need their burners, gas pressure and heat exchanger inspected. Heat pumps need their outdoor coil, refrigerant charge and defrost operation checked, because a heat pump uses the same refrigerant circuit to heat and to cool. Several of the core tasks below come straight from ENERGY STAR’s maintenance checklist, which recommends checking the heating system in the fall and the cooling system in the spring.
| Task | Gas furnace | Heat pump |
|---|---|---|
| Check thermostat settings and operation | Yes | Yes |
| Tighten electrical connections, measure voltage and current on motors | Yes | Yes |
| Lubricate moving parts | Yes | Yes |
| Check the condensate drain | Yes (high-efficiency models) | Yes |
| Inspect and replace the air filter | Yes | Yes |
| Test the ignition system and flame sensor | Yes | No |
| Check gas connections, gas pressure and burner combustion | Yes | No |
| Inspect the heat exchanger for cracks | Yes | No |
| Check the flue and venting | Yes | No |
| Clean and inspect the outdoor coil | No | Yes |
| Check refrigerant charge | No | Yes |
| Test the defrost cycle and backup (auxiliary) heat | No | Yes |
| Check blower components and airflow | Yes | Yes |
| Run a full start, heat and shut-off cycle | Yes | Yes |
A furnace tune-up typically takes 1 to 2 hours, according to Carrier, and longer if the technician finds a problem. If something needs fixing, ask what it is and what the repair costs before any work starts.
Why do the heat exchanger and carbon monoxide checks matter?
The heat exchanger check is the most important part of a gas furnace tune-up, because a cracked heat exchanger can let carbon monoxide into your home. The heat exchanger is the sealed chamber that keeps combustion gases separate from the air your furnace blows through the house; those gases are supposed to leave through the flue. Metal that heats and cools thousands of times can crack, and a crack is not something you can see or smell from the living room. Carbon monoxide is odorless and colorless, and exposure causes headaches, dizziness and nausea, and at high levels it can kill. If a First Choice technician finds your furnace is unsafe, we shut it off to protect your family and walk you through the repair or replacement options. Heat pumps burn no fuel, so this risk applies to gas, oil and propane furnaces, not to a heat pump on its own.
Every home with a fuel-burning appliance or an attached garage should also have working carbon monoxide detectors. Our post on whether you need a carbon monoxide detector in your Fredericksburg home covers where to put them.
How much does a heating tune-up cost in Fredericksburg?
First Choice Heating & Air Conditioning prices heating tune-ups per system, so a home with a furnace for the main floor and a heat pump for the upstairs counts as two systems. We post seasonal tune-up offers on the heating and air conditioning specials page. A tune-up price normally covers the inspection, cleaning and safety checks, and parts and repairs are priced separately. When you compare companies, ask whether each tune-up includes a heat exchanger inspection and what happens if the technician finds a problem.
| What changes the cost | Why |
|---|---|
| Number of systems | Each furnace or heat pump is inspected and priced on its own. |
| Repairs found during the visit | Parts such as a capacitor, flame sensor or igniter are quoted separately. |
When should you schedule a heating tune-up?
Schedule your heating tune-up in early fall, before you need the heat every night. ENERGY STAR gives the same advice: contractors get busy once winter arrives, so check the heating system in the fall and the cooling system in the spring. A simple way to remember is to book around the clock changes. Gas furnace owners need one visit a year, in the fall. Heat pump owners should plan on two, a heating check in the fall and a cooling check in the spring, because the same equipment runs most of the year. If you have already turned your heat on and noticed short cycling, weak airflow, a burning smell that doesn’t fade, or a heat pump that can’t keep up on cold days, don’t wait for a tune-up slot. Call for a repair visit instead.
If your heat pump struggles in a cold snap, our guide on why a heat pump can’t keep up when it’s really cold outside explains what’s normal and what isn’t.
One-time tune-up or a maintenance plan?
A one-time tune-up makes sense if you only want the fall check. A First Choice maintenance plan makes sense if you want both seasonal check-ups handled for you, plus member benefits on repairs. Both get your system inspected. The difference is what happens the rest of the year. Plan members get priority scheduling for service calls, which matters most on the first cold weekend when everyone’s heat goes out at once, and they get discounts on parts and service calls.

| One-time tune-up | Maintenance plan | |
|---|---|---|
| Fall heating check | Yes | Yes |
| Priority scheduling for service calls | No | Yes |
| Discounts on parts and service calls | No | Yes |
| Best for | Gas furnace homes that want one fall visit | Heat pump homes and anyone who wants priority service in a cold snap |
What can you do yourself before winter?
You can handle a few simple tasks between professional visits, and they make the tune-up more effective. None of them replace the safety checks on a gas furnace.
- Check the air filter monthly, as ENERGY STAR recommends, and replace it when it’s dirty.
- Test your carbon monoxide detectors and replace the batteries.
- Keep storage and anything flammable away from the furnace.
- Clear leaves and overhanging branches from the outdoor heat pump unit.
- Open and vacuum vents and return grilles.
- Shut off outside faucets and disconnect hoses so pipes don’t freeze.
- Seal drafts around doors and windows.
Frequently Asked Questions
Does skipping a tune-up affect my warranty?
It can. Some manufacturer warranties require proof of regular professional maintenance, so read your warranty terms and keep every service record. Keep the paperwork from every visit with your warranty documents.
Is it safe to turn on my furnace before the tune-up?
Usually, yes, if the furnace ran without problems last winter and has been maintained. A light dusty smell for the first few minutes after months off is common. A burning smell that doesn’t fade means you should shut the system off and call us. If you smell rotten eggs, which can mean a gas leak, leave the house and call your gas utility or 911 from outside.
How long does a heating tune-up take?
Carrier puts a furnace tune-up at 1 to 2 hours, including the inspection, cleaning and testing. Homes with more than one system take longer, since each unit gets its own inspection.
Do heat pumps need a tune-up if they don’t burn gas?
Yes. A heat pump has no heat exchanger to crack, but its refrigerant charge, outdoor coil, defrost cycle and backup heat strips all need checking. A problem with any of them shows up as a heat pump that can’t keep the house warm on cold days.
