An HVAC that turns on but isn’t heating usually means the furnace is running but the burners aren’t making flame or the heat isn’t getting delivered to rooms. The most common real-world cause is an ignition issue—like a dirty flame sensor or a failed hot-surface igniter—so the control board runs the blower but won’t keep the gas burning. Other likely categories include airflow restrictions, fuel or power supply problems, and thermostat or safety control faults. Our technicians see these patterns often in homes we service around Ivesdale. If needed, we also offer 24/7 emergency heating repairs with flat-rate pricing and a 100% satisfaction guarantee.
Try these quick checks before calling:
- Set thermostat to Heat, fan to Auto, and raise the setpoint at least 5°F.
- Replace a dirty air filter to restore airflow.
- Look for a blinking error light/code on the furnace access panel.
- If gas, confirm the gas valve is on; don’t keep resetting igniters or safety switches.
If you smell gas or the unit starts and stops without flame, turn it off and schedule professional service.

An HVAC system that turns on but doesn’t heat usually points to a control or heat-making problem, like incorrect thermostat settings, a failed igniter or flame sensor, restricted airflow, or a safety lockout that lets the blower run without heat. The most common cause we find is a dirty filter or blocked return starving the furnace for air, which can trigger limit switches and shut the burners off. A tech will also check gas supply, ignition, sensors, and for heat pump systems, defrost and refrigerant charge. One telltale clue is a furnace that lights, heats briefly, then blows cool air—that often means the flame drops out due to a weak sensor.
We service homes throughout the Hammond, IL area and can handle quick diagnostics and repairs, including 24/7 emergency no-heat service.
Before you call, try these quick checks:
- Set thermostat to Heat and raise the setpoint 5°F.
- Replace a clogged filter and clear returns.
- Confirm the furnace switch and breaker are on.
- For heat pumps, clear ice/debris from the outdoor unit.
If you smell gas or the breaker trips repeatedly, turn the system off and call a professional immediately.

An air conditioner that won’t turn on even though the thermostat is set to Cool usually points to a power, control, or system safety lockout. The most common cause is a tripped breaker or blown fuse cutting power to either the indoor air handler or the outdoor condenser. Other likely issues include dead thermostat batteries, a condensate float switch tripped by a clogged drain, an iced coil from a dirty filter, or a failed start component. Technician insight: if the indoor blower runs but the outdoor unit is silent, suspect the capacitor or contactor; if both are off, start at the electrical panel. Our technicians see a surge of first-heatwave no-cool calls across the Mansfield area.
Before you call, try these simple checks:
- Reset tripped HVAC breakers and verify the outdoor disconnect is fully seated.
- Replace thermostat batteries, select Cool and Auto, and lower the setpoint 5°F.
- Look for water in the drain pan or a raised float switch and clear the drain if safe.
- Replace a clogged air filter and let any iced coil thaw before retrying.
If it still won’t start after these checks, avoid repeated resets and schedule a diagnostic to protect the compressor.

If your HVAC system needs emergency repair now, call Lanz Plumbing, Heating & Cooling, Inc. for 24/7 dispatch and we’ll send a technician right away. Most emergency no-heat or no-cool calls trace to issues like a failed igniter, bad flame sensor, blower motor problems, or thermostat malfunctions, which we diagnose and fix promptly. Our technicians follow a clear repair process—assess, test, adjust, then clean up—so you know exactly what’s happening. We offer flat-rate pricing, no after-hours fees, and a 100% satisfaction guarantee after the core diagnosis begins. Our team handles urgent calls across the Champaign–Urbana area every day.
While you wait, take these quick steps:
- Set the thermostat to Off and fan to Auto if you smell burning, see smoke, or find water around equipment.
- Check the breaker and the furnace/air-handler switch; restore power only if tripped once.
- Replace a severely clogged filter to improve airflow.
- For furnaces, note any error light blinks; for AC, don’t chip ice off coils.
Do not keep trying to run the system until a technician inspects it.

The average cost to fix a furnace typically falls between $200 and $1,500, depending on which component failed and the repair scope. Many common part swaps, like motors and control boards, usually land in the mid range, while major heat exchanger work sits at the high end. We use flat-rate pricing so you know the number before work starts, and final pricing is confirmed after an on-site diagnostic. Our team services the greater Champaign area and nearby communities, including work around Bellflower.
Typical example ranges from our pricing guides:
- Circuit board replacement: $200–$500
- Blower motor replacement: $300–$600
- Heat exchanger repair/replacement: $300–$1,500
If your furnace is down, schedule a diagnostic so a technician can quote the exact repair before any work begins.

The best AC setpoint when it’s 100°F outside is about 75–78°F, roughly a 20°F drop from outdoors, which aligns with how most systems are designed to perform. Most comfort loss on triple-digit days comes from long runtimes and heat gain, not a “too-high” thermostat, and cranking it lower won’t cool faster.
Start cooling early, keep blinds closed, and run ceiling fans to make 78°F feel cooler; technicians often call this “stacking efficiency” before the day peaks. Our team sees during heat waves in the Cerro Gordo area that systems pushed into the low 60s can ice the coil and actually lose capacity.
For extreme heat, use these settings and checks:
- Hold 78°F by mid-morning; nudge to 75–76°F only if the home maintains it.
- Limit setbacks to 3–4°F; big swings overwhelm the system.
- Keep the fan on Auto for better humidity control; use ceiling fans for comfort.
- If supply air isn’t about 15–20°F cooler than room air, check a dirty filter or icing.
If the home climbs above 80°F or you see frost on the refrigerant line, turn cooling off, set the fan to On for 30 minutes, and schedule service.

If your air conditioner clicks but won’t turn on, start with quick power and thermostat checks, then schedule service if it still won’t start. The most common culprits are a tripped breaker, a thermostat issue, or a failed start component that lets the relay click without the motor running. A rapid series of clicks can hint at a stuck contactor, while one solid click with silence often points to a weak capacitor. Our team handles this problem often across Champaign County and offers 24/7 emergency AC repairs.
Try these safe checks first:
- Set thermostat to Cool/Auto, lower 5°F, replace batteries.
- Verify the AC breaker and outdoor disconnect are ON.
- Wait 5 minutes after any reset before retrying.
If you smell burning, hear rising electrical buzz, or the breaker trips again, stop and book a professional diagnosis to prevent damage.

The average furnace repair cost for homeowners typically runs about $200 to $1,500, based on our published ranges for specific repairs. The biggest driver is the part being fixed: circuit boards are commonly $200–$500, blower motors $300–$600, and heat exchanger work $300–$1,500, with labor and access influencing the total. Final pricing is confirmed after an on-site diagnostic. We serve the area around Indianola and use flat-rate pricing so you know the total before work begins.
Consider repair vs. replacement when you notice:
- Repeated breakdowns on an older system
- A cracked heat exchanger due to safety risk
- A repair estimate that nears the cost of a new unit
Schedule a diagnostic to get an exact quote and clear options before you approve any work.

Emergency HVAC repair is rapid, any-time service to stop a no-heat, no-cool, or unsafe equipment failure and restore safe operation. The most common trigger is a complete loss of heating or cooling during extreme weather. Failures tied to safety, power, or active water damage also meet the threshold, and continuing to run the system can worsen damage. If your furnace locks out repeatedly, the control board is protecting the unit; forcing it to run can turn a small fix into a major one. We regularly handle urgent calls in and around Sibley. After diagnostics, a technician stabilizes the system, reviews clear options, and proceeds with flat-rate, 24/7 emergency service.
Call for emergency help if you notice:
- No heat near freezing temps or no cooling during dangerous heat.
- The smell of gas, burning wiring, or visible smoke.
- Breakers tripping, sparking at the unit, or the system won’t stay on.
- Rapid water leaks from the furnace or air handler threatening ceilings or electronics.
If you suspect a gas leak, leave the building and call your gas utility before contacting an HVAC professional.

HVAC repair for homeowners usually includes a professional diagnosis, targeted part repair or replacement, and a full system test to restore safe, reliable heating or cooling. Most service calls begin with no-heat or no-cool complaints that trace back to a failed part, airflow restriction, or an electrical control fault. Your technician confirms the root cause, explains options, and completes the fix; minor issues are repaired, aging systems with major failures may warrant replacement quotes, and borderline problems can be monitored. Our technicians service homes throughout the Mahomet area with flat-rate pricing, 24/7 emergency response, and a workmanship standard that includes post-repair testing and cleanup.
Typical visit steps and fixes may include:
- System diagnostics and performance testing
- Thermostat, sensor, and electrical checks
- Furnace components like igniters, flame sensors, blower motors, or heat exchangers
- Refrigerant leak inspection, airflow measurements, and filter replacement
- Final run test, adjustments, and work-area cleanup
Turn off the unit and call a professional if you smell gas, burning odors, or see tripped breakers that won’t reset.

Residential HVAC maintenance with Lanz Plumbing, Heating & Cooling, Inc. costs $29.95–$39.95 per month through our Comfort Family plans, which is about $360–$480 per year. Additional fees may apply if you have multiple HVAC systems or water heaters in your home. These plans center on two seasonal precision visits for your HVAC and plumbing and add 15–25% repair discounts with no emergency dispatch fees. Standalone tune-up pricing can vary by system and scope, and final cost is confirmed after a technician evaluates your equipment. Our team services homes throughout the Champaign-Urbana area, including Savoy. A thorough visit often pays for itself by catching small airflow or ignition issues before they become mid-season breakdowns.
Typical tasks during a furnace or AC maintenance visit include:
- Inspecting and cleaning burners and heat exchangers
- Checking and tightening electrical connections
- Replacing or cleaning air filters
If you've missed a season, book maintenance before peak heat or cold to lower the risk of a no-cool or no-heat call.

HVAC techs don't have a single universal hourly rate; Lanz Plumbing, Heating & Cooling, Inc. uses flat-rate pricing instead of hourly charges. Your final cost depends on the problem found, any parts required, and whether service is routine or urgent. Flat-rate pricing means the price is quoted up front after diagnosis, not tied to how long the repair takes, which protects you from overtime surprises. If a repair nears the cost of a failing system or you face frequent breakdowns, a replacement conversation is sensible. We price work this way for homeowners throughout the Gibson City area. Final pricing is confirmed after an on-site evaluation.
Here's how pricing typically works with us:
- We diagnose first, then present a written flat-rate before work begins.
- Comfort Family members get guaranteed response (same-day or within 24 hours), $49 Orange or $59 Blue dispatch fees, no emergency dispatch fees, and 15% or 25% off service repairs.
- Flat-rate covers labor time; parts are itemized so you see each cost.
Ask for a clear, written flat-rate quote and keep any replaced parts for your records.

Most HVAC repairs can often be completed the same day after diagnosis, but the actual fix time depends on parts availability and the complexity of the failure. The most common delay is waiting on a specialty part when a control board, compressor, or proprietary component has to be ordered instead of using a common part. We service homes throughout the Buckley area and see that quick fixes are usually tied to issues a tech can resolve right at the unit once the fault is confirmed. Comfort Family members receive guaranteed service windows (within 24 hours on Blue; same-day on Orange) with no emergency dispatch fees, which can speed scheduling when timing is critical.
Watch for signs that point to longer timelines:
- Special-order or brand-specific parts
- Major refrigerant or compressor issues
- Extensive electrical or airflow problems
Final pricing and timing are confirmed after an on-site diagnostic visit.

To reset an air conditioner safely, shut off power to the system, wait a few minutes, then restore power and restart from the thermostat. Most resets follow a power surge or tripped breaker; the pause lets the control board clear and refrigerant pressures equalize so the compressor doesn't hard‑start. We also serve homes near Homer, so help is close if the reset doesn't hold. A small technician insight: a full five‑minute wait prevents the compressor from pushing against high head pressure.
Do this in order:
- Set thermostat to Off; set Fan to Auto.
- Turn off the outdoor disconnect or switch, if present.
- Switch the HVAC breaker off at the main panel.
- Wait 5–10 minutes.
- Turn on the outdoor disconnect, then the breaker.
- After 5 more minutes, set thermostat to Cool and lower the setpoint.
- Confirm steady airflow and normal sounds.
If the breaker trips again, airflow stops, or you smell burning, stop and call a licensed HVAC technician.

To reset an air conditioner after a power issue, turn the thermostat to Off, reset the AC breaker once, wait 5–10 minutes, then turn cooling back on. Most power problems trip a circuit breaker or a safety that protects the compressor from short-cycling. Our technicians see this often in Georgetown homes after storms or brownouts, and a careful reset usually restores normal cooling. If the system won't restart or trips again, that points to a failing part and needs service. We also offer 24/7 emergency repairs when a reset won't hold.
Try these steps in order:
- Set thermostat to Off; set fan to Auto.
- Reset the dedicated AC breaker once; do not keep flipping it.
- Confirm the furnace/air-handler switch (looks like a light switch) is On.
- After 5–10 minutes, set thermostat to Cool and a few degrees lower to test.
Stop and call a pro if you smell burning, see smoke, or the breaker trips again.

You can often fix an HVAC that isn't blowing hot air by checking simple causes like thermostat settings, a clogged filter, or a tripped breaker. The most common issue we see is a dirty filter that makes the furnace overheat and shut the burners off for safety. If basic checks don't help, a technician should test parts like the igniter, flame sensor, blower motor, or heat pump controls; our team handles this daily in the Allerton area.
Try these quick checks before you call:
- Set the thermostat to Heat, Fan Auto, and raise the setpoint 5°F.
- Replace a dirty air filter to restore airflow and prevent limit switch trips.
- Confirm the furnace switch and breaker are on, and the blower door is firmly latched.
- For gas heat, make sure the gas valve is on; if you smell gas, stop and ventilate.
If you ever smell gas or see scorch marks, leave the area and call a professional right away.

Yes, an HVAC system can run 24 hours during extreme weather without instant damage, but nonstop operation often points to a condition that accelerates wear. The most common cause is a thermostat target that’s unrealistic for the day; other frequent drivers are a clogged air filter, undersized equipment, low refrigerant, or restricted airflow. Continuous duty strains compressors and blower motors and can lead to coil icing or overheating. Technicians see this most during heat waves and cold snaps; our team regularly works in homes around Fisher and knows when “always on” is normal versus a fixable fault.
Quick checks you can do now:
- Set the thermostat fan to Auto, not On.
- Replace a dirty filter and make sure returns aren’t blocked.
- Check for frost on the refrigerant line or indoor coil.
- If air from vents feels weak or barely cooler, schedule service.
If the unit runs nonstop for a day or starts short cycling, turn it off to prevent damage and book a diagnostic.
