Why Is My HVAC Heater Not Turning On At All?
An HVAC heater that won’t turn on usually points to a power supply issue, thermostat problem, safety lockout, or an ignition failure. The most common cause is a thermostat not calling for heat or a tripped breaker or switch cutting power. Some systems pause to protect themselves after faults, and many control boards lock out after a brief power blink until fully reset. Our EPA-certified technicians handle these…
Is HVAC repair cheaper than replacement for older units?
HVAC repair is usually cheaper upfront than replacing an older unit, but replacement can be the better value when repeated issues or big-ticket failures start driving total costs higher. The most common pivot point is when age-related problems add up, making reliability and efficiency slip while bills and visits rise. A technician can compare both options side by side, including energy use and warranty coverage, so…
Should I turn off AC if it's not cooling?
Yes—turn the AC off if it’s running but not cooling to prevent damage and wasted energy. Most cases point to an airflow or refrigeration problem, and running it can freeze the coil or strain the compressor. Powering it down protects the system while you check basics and arrange service. Our team handles this issue often for homeowners throughout the Paxton area. For urgent situations, Lanz offers 24/7 emergency…
How Long Does It Usually Take To Get HVAC Fixed?
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…
What Should My AC Be Set At When It's 100 Degrees Outside?
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.
Can HVAC Run 24 Hours Without Damaging The System?
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…
How Much Do HVAC Techs Charge Per Hour?
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…
How Do I Reset My Air Conditioner Safely?
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…
Why Is My HVAC Turning On But Not Heating The House?
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…
What Is Emergency HVAC Repair, And When Do You Need It?
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…
What is the average cost to fix a furnace?
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…
What Does HVAC Repair Usually Include For Homeowners?
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…
What Should I Do If My AC Is Clicking But Not Turning On?
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.…
How Can I Fix My HVAC When It Is Not Blowing Hot Air?
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…

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.

How Can I Reset My Air Conditioner to Fix Power Issues?
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…
Why Is My Air Conditioner Not Turning On Despite Thermostat Set to Cool?
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…

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.

Our technicians follow a clear repair process—assess, test, adjust, then clean up—so…
Why Is My HVAC Not Heating Even Though It Turns On?
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…
