Watch for these symptoms that mean your furnace needs professional attention:
Our technicians follow a systematic approach to find why your furnace won’t ignite. First, we check the thermostat settings and power supply to rule out simple issues. Then we inspect the igniter—the part that actually lights the burners. A faulty igniter is one of the most common reasons a furnace fails to start, and we carry replacement parts for all major brands.
Next, we test the flame sensor. This safety device shuts off gas flow if it doesn’t detect a flame. When it gets dirty or wears out, it prevents the furnace from lighting. We also check gas pressure, voltage at the blower motor, and examine the control board for fault codes. If your issue involves a gas furnace, we perform a full leak check and verify proper venting before restarting the system.
For homes with electric furnaces, we test heating elements and capacitors. If the igniter is the culprit, our technicians often recommend upgrading to a more reliable hot surface igniter. Many homeowners across the region also ask us about furnace not heating repair when their system turns on but doesn’t warm the home—these issues often share root causes.

Rick and his crew are awesome you must use these people.Posted on Ed & Alice WaltonTrustindex verifies that the original source of the review is Google. We are happy with HVAC Master service. Always prompt and always there when they say they'll be there. ( Which is a rare trait these days). Very nice and knowledgeable crew. Not so happy with the RUUD heat pump unit we bought from them 6 years ago. In the first year or so had compressor replaced, worked right for a short time, then had to run it on emergency heat because we got tired of it blowing cold air for a hour and a half before it automatically kicked on emergency heat. Then had coils replaced last month because the air conditioner quit blowing cold air..... Under warranty....but still had to pay $600. labor. So we'll see when winter comes, what will be next... Update... October 2025 Heat pump seems to be working good. And still happy with HVAC Master. Well run business. Prompt and knowledgeable.Posted on Debbie WolfeTrustindex verifies that the original source of the review is Google. We love HVAC Master LLC. They are always professional and show up on time.

When HVAC emergencies happen, fast response and clear action matter most.
Emergency calls are prioritized so heating or cooling issues are addressed without delay.
Technicians concentrate on stabilizing the system and restoring comfort as quickly as possible.
Our team regularly handles sudden system failures during extreme weather conditions.
Several issues could cause this. The igniter may be cracked or worn out, the flame sensor could be dirty or faulty, or there might be a problem with gas supply. Our technicians use diagnostic tools to test each component and find the exact cause.
For gas furnaces, never run the system if you smell gas or notice a yellow flame instead of blue. For electric furnaces, a failure to start won’t create an immediate safety hazard, but you risk damage to components if the issue worsens. Call us to diagnose the problem before it becomes a bigger repair bill.
Most repairs take 1-2 hours once we identify the problem. Igniter and flame sensor replacements are typically quick jobs. Complex issues involving the control board or gas valves may take longer. We carry common parts on our trucks for faster service across the area.
This depends on the furnace’s age, repair costs, and efficiency. If your furnace is over 15 years old and needs major repairs, replacement might save money long-term. We provide honest recommendations so you can decide based on your specific situation.
Leave your home immediately and call your gas company from outside. Do not operate light switches, electronics, or anything that could create a spark. Once safety is confirmed, contact us for a thorough gas furnace inspection.
We start with a comprehensive evaluation of your needs and walk through your goals together so the plan fits your home.
We present clear options and an up-front price so you can make the right call with full confidence — no pressure and no surprises.
Our certified team completes the work on schedule and checks back in afterward to make sure everything runs exactly the way it should.
We proudly serve the Ozarks region of Missouri, Branson, Nixa, Ozark, Rogersville, and surrounding Missouri communities with reliable HVAC services. No matter where you are in our service area, we deliver the same trusted commitment to quality and care.
Our technician tests the thermostat, verifies power supply, inspects the ignition system, and checks safety controls. Any faulty components are identified and explained before repair work begins. If replacement parts are needed, we discuss options and timeline before proceeding.
If your furnace produces no heat, the pilot light will not stay lit, or you hear unusual noises and smell gas, call us right away. Frequent on‑off cycling and a sudden increase in your energy bill can also indicate a problem that needs prompt attention. Early detection helps prevent larger issues and keeps your home safe.
Most repairs that restore a non‑starting furnace take one to two hours, depending on the diagnosis. If the issue requires parts that are not on the truck, the visit may extend while we source the correct components. We keep you informed throughout the process so you can plan your schedule.
The total cost depends on the parts required, the complexity of the repair, and the labor involved. If the furnace is older or requires special order components, the price may rise. We provide a detailed estimate before starting any work, so there are no surprises. Your service agreement and any applicable warranties can also influence the final amount.
Our technician arrives, reviews your description of the problem, and performs a thorough inspection of the furnace and its components. Once the issue is identified, we explain the findings and outline the recommended repair steps. After obtaining your approval, we complete the repair, test the system, and ensure everything operates safely.
