Let’s keep this simple. A furnace tune up is a visit from a licensed HVAC pro to clean, test, and set your system so it heats safely and well all winter. This matters in Kansas City because our weather swings fast across Jackson, Johnson, Clay, and Wyandotte counties. One day it feels fine in Waldo or Brookside. The next day a cold front hits. A tune up helps you avoid breakdowns and high bills.
Routine maintenance can prevent failures and extend equipment life. You also get peace of mind that carbon monoxide and gas safety checks are done. Here is exactly what a real tune up should include for a Kansas City home.
What a furnace tune up is
A tune up is a full system check. The tech cleans key parts, measures how the system starts and runs, and makes small fixes. You should get a written checklist when the visit ends. If the tech finds a problem, you should get a clear estimate before any repair.
Step by step: what the tech should do
- Arrival and safety
The tech reviews your furnace area for clear space and checks shutoff switches. They verify the model, fuel type, and filter size. They put on shoe covers to protect your floors. - Thermostat and start up
They set the thermostat to heat and confirm the system starts clean. They check that the display is accurate and that settings hold. - Filter and airflow
They inspect and replace the air filter if needed. They check supply and return vents for blockages. Good airflow keeps rooms even and lowers stress on the blower. - Burners and flame sensor
For gas furnaces, the tech removes dust from the burners so the flame lights smooth. They clean the flame sensor so the furnace does not shut off by mistake. - Ignition system
They test hot surface or spark ignition for fast, steady light. Slow ignition wastes gas and can cause noise. - Heat exchanger inspection
They look for signs of cracks or rust. If they see a concern, they explain it and show you what they found. This is a key safety step. - Carbon monoxide and venting
They measure carbon monoxide at the furnace and check the flue for blocks or loose joints. Venting must be tight and clear. - Gas pressure and connections
They test inlet and manifold pressure and tighten fittings if needed. Proper pressure protects parts and keeps heat steady. - Electrical checks
They tighten low voltage and high voltage connections. Loose wires cause shorts and no heat calls. - Blower motor and belt
They inspect the blower wheel for dust buildup and balance. They test motor amps against the label. If there is a belt, they check tension and wear. - Temperature rise test
They measure the air temp going in and coming out of the furnace. The difference must match the label range. If it is too high, you may have airflow issues. If it is too low, you may have gas or control issues. - Condensate system
For high efficiency units, they clear the drain trap and lines. A clog can shut the system down. - Safety controls
They test limit switches, rollout switches, and pressure switches. These protect the furnace if something goes wrong. - Cycle and confirm
They run the system through a few cycles to confirm smooth start and stop. They listen for rattles and whines. - Written checklist and advice
They give you a written list of what they checked and cleaned. They note any parts to watch and any repairs with prices and options.
How long it should take and what it costs
Most tune ups take about an hour. Very dirty systems can take longer. Costs vary by company and season, but the value is in the safety checks, cleaning, and small fixes that stop bigger problems later. Ask for clear pricing up front.
What to ask your HVAC contractor
Use plain questions. You do not need technical words.
- Are you licensed and insured in Missouri or Kansas
- Do you perform background checks on your techs
- What exact steps do you include in your furnace tune up
- Will I receive a written checklist when you finish
- If you see a problem, can you show me the part and explain my options
- What warranties do you provide on any repair
What to expect in a written estimate
A good estimate lists the part, the labor, the total price, and the warranty. It should also state how long the repair will take and if there are options like repair now or monitor. If something is unclear, ask the tech to slow down and explain it.
Simple homeowner checklist before the visit
- Change the filter if you know it is dirty
- Move boxes or storage away from the furnace
- Write down any noises, smells, or error codes
- Check your thermostat batteries if it uses them
- Note any cold rooms so the tech can look at airflow

Local tips for Kansas City homes
Homes in Overland Park and Olathe often have finished basements. Make sure supply and return vents are open in those rooms. In Lee’s Summit and Liberty, older ductwork can leak at joints. Ask the tech to look for air leaks if rooms feel uneven. In Waldo and Brookside, many homes have tight mechanical rooms. Keep that area clear so the furnace can breathe and the tech can work safely.
Common mistakes to avoid
- Waiting until the first freeze to call
- Skipping the written checklist
- Ignoring airflow and filter changes
- Picking a random ad that sells your info
- Choosing by the lowest price only
