Frequently Asked Questions

1-How often should I change my furnace filter?

It’s generally recommended to change your furnace filter every 1-3 months, depending on factors like the type of filter, the level of use, and your home environment. If you have pets, allergies, or high traffic in your home, you may need to change it more frequently. A clogged or dirty filter can reduce your furnace’s efficiency, affect air quality, and even cause the system to overheat.

For personalized advice, our experts at Mannix Heating & Air Conditioning can help guide you on the best maintenance schedule for your furnace to keep it running smoothly year-round.

2-Why is my furnace blowing dust or odors?

If your furnace is blowing dust or odors, there are a few common reasons:

Dirty or Clogged Filter: A dirty filter can cause dust and debris to be circulated through your home. It's important to regularly change or clean your furnace filter to prevent this.
Dust Build-Up in the Ducts: Over time, dust and debris can accumulate in your ductwork, and when the furnace turns on, it can blow these particles into your living space. A professional duct cleaning can help remove this buildup.
Old or Moldy Furnace Components: If your furnace hasn't been properly maintained or cleaned, dust, mold, or mildew can build up in the system, causing odors when the furnace runs. A technician can inspect and clean components like the heat exchanger, blower, and ducts.
Burning Dust: When a furnace is first turned on for the season, dust that has settled on the heating elements may burn off, causing a temporary burning smell. This is typically harmless but should dissipate after the first few uses.
Gas Leaks (for gas furnaces): If you notice a strong odor of gas, turn off your furnace immediately and contact a professional. This can be a serious safety concern.

If these odors or dust persist, it’s best to have a professional from Mannix Heating & Air Conditioning inspect and clean your furnace to ensure everything is in proper working condition.

3- What should I do if my furnace smells like gas?

If your furnace smells like gas, it’s important to act quickly because this could indicate a gas leak, which is a serious safety concern. Here’s what you should do:

Turn Off the Furnace: Immediately turn off your furnace to stop the flow of gas.
Evacuate the Area: Leave your home or building as soon as possible. Avoid using any electrical devices, light switches, or anything that could potentially create a spark.
Call the Gas Company or Emergency Services: Once you're safely outside, call your gas provider or emergency services to report the gas smell. They can dispatch professionals to check for leaks and ensure your safety.
Do Not Re-enter the Building: Do not go back inside until it has been confirmed by the authorities that it is safe to do so.

Gas leaks are dangerous and should be treated with extreme caution. If you detect a gas smell, don’t hesitate to contact Mannix Heating & Air Conditioning. Our team is ready to help inspect and repair your furnace to keep your home safe and comfortable.

4-Why is the furnace running continuously?

If your furnace is running continuously, it could be due to several potential issues:

Thermostat Settings: Check your thermostat. If it's set to the "On" position instead of "Auto," the blower will run continuously. Make sure the thermostat is set to "Auto" so the blower only runs when the furnace is actively heating.
Dirty Air Filter: A clogged air filter can restrict airflow, causing the furnace to overheat. As a safety measure, the furnace may continue running to prevent damage. Regularly replace or clean the air filter to avoid this issue.
Malfunctioning Limit Switch: The limit switch is a safety feature that controls the furnace's operation. If it's malfunctioning, it could cause the furnace to keep running even when it’s not needed. A technician will need to inspect and potentially replace the switch.
Faulty Blower Motor or Relay: If the blower motor or relay is malfunctioning, the blower may keep running even when the furnace is not heating. This can be caused by a faulty motor, relay, or electrical component, which requires professional repair.
Furnace is Not Reaching Set Temperature: If your furnace is running constantly without reaching the desired temperature, there could be a problem with the heating elements or thermostat calibration. A technician can diagnose and fix the problem.
Poor Insulation or Leaks: If your home is poorly insulated or has leaks, the heat produced by your furnace might be escaping, causing it to run longer to maintain the desired temperature.

If your furnace continues running non-stop, it’s a good idea to contact Mannix Heating & Air Conditioning. Our team of experts can quickly identify the cause and ensure your furnace is working efficiently again.

5-Why is my furnace not turning on?

If your furnace isn't turning on, there are several possible reasons. Here are the most common ones:

Thermostat Issues:
- Incorrect Settings: Ensure the thermostat is set to "Heat" and that the temperature is set higher than the current room temperature.
- Dead Batteries: If you have a battery-powered thermostat, the batteries may need to be replaced.
- Faulty Thermostat: If your thermostat is malfunctioning, it may not be sending the correct signal to the furnace to turn on. A technician can diagnose and replace it if necessary.
Tripped Circuit Breaker or Blown Fuse:
- Check your furnace’s circuit breaker or fuse box. If the circuit has been tripped, flip the breaker back on. If the fuse is blown, it will need to be replaced.
Gas Supply Issues (for Gas Furnaces):
- If you have a gas furnace, ensure the gas valve is open. If there’s a problem with the gas supply (e.g., a shut-off valve or a gas outage), the furnace won’t be able to ignite.
- If you suspect an issue with the gas supply, contact your gas provider.
Dirty or Clogged Air Filter:
- A dirty air filter can restrict airflow, causing the furnace to overheat or shut off as a safety measure. Replace or clean the filter and try turning the furnace back on.
Pilot Light or Ignition Problems:
- For older furnaces with a pilot light, the pilot light may be out. If you're comfortable doing so, you can try relighting it according to the manufacturer’s instructions.
- Newer furnaces use electronic ignition systems, and if this system fails, the furnace may not turn on. This could require a professional repair.
Dirty or Blocked Flame Sensor:
- The flame sensor detects whether the furnace has ignited. If it's dirty or faulty, the furnace might fail to turn on or shut off shortly after starting. A technician can clean or replace the sensor.
Faulty Limit Switch:
- The limit switch monitors the temperature inside the furnace. If it's faulty, the furnace may fail to start or run continuously. A technician will need to inspect and replace the limit switch if necessary.
Electrical Issues:
- A malfunctioning or disconnected wire can prevent your furnace from turning on. Check for any obvious issues or call a technician to inspect the electrical components.

If your furnace still isn’t turning on after checking these issues, it’s best to contact Mannix Heating & Air Conditioning. Our experienced team can diagnose and repair your furnace to restore warmth and comfort to your home.

6- Why is my furnace making strange noises?

If your furnace is making strange noises, it could be a sign of an underlying issue. Here are some common furnace noises and what they might mean:

Banging or Popping Noises:
- Delayed Ignition: This sound is often caused by a delay in the ignition of the gas burners. It can cause gas to accumulate before igniting, resulting in a loud bang or pop when the gas finally ignites. This is typically due to a dirty burner or issues with the ignition system.
- Duct Expansion/Contraction: Sometimes, as heated air moves through the ducts, the metal ducts expand or contract, causing popping or banging noises. This is generally normal, but if it's excessive, it could indicate a problem with your ductwork.
Squealing or High-Pitched Whistling:
- Worn Blower Belt: If you hear a squealing noise when the furnace starts, the blower belt could be worn or loose. Replacing the belt should resolve the noise.
- Dirty or Dry Blower Motor: A squealing sound could also come from a blower motor that needs lubrication or cleaning. In this case, a technician will need to clean or lubricate the motor to resolve the issue.
Rattling or Scraping:
- Loose Parts: Rattling noises can occur if there are loose parts inside the furnace, such as screws, panels, or components that have become loose over time.
- Scraping Noises: If the noise sounds like metal scraping, it could indicate a problem with the blower wheel, such as debris inside or damage to the fan blades. This requires immediate attention, as it can cause further damage if left unchecked.
Humming or Buzzing:
- Electrical Issues: A humming or buzzing noise may indicate an electrical issue with the furnace, such as a problem with the transformer or capacitor. It could also be a sign of a malfunctioning motor.
- Vibration: Sometimes, a buzzing noise can come from vibrating components inside the furnace or ductwork. This could be caused by loose parts or the furnace being placed on an unstable surface.
Gurgling or Dripping Sounds:
- Clogged Drain Line: If your furnace has a condensation line (typically with high-efficiency furnaces), a gurgling sound might indicate that the line is clogged, causing water to back up. This can lead to water damage if not addressed.
Clicking or Ticking Sounds:
- Normal Start-Up Noise: Some clicking or ticking sounds are normal during start-up as the furnace ignites or as components like the gas valve or ignition system cycle.
- Faulty Gas Valve or Ignition System: If the clicking is excessive or repetitive, it could indicate a problem with the gas valve or ignition system, which may require a technician to inspect.

If your furnace continues to make strange noises, it's a good idea to have a technician from Mannix Heating & Air Conditioning inspect it. Our experienced team can quickly identify the source of the noise and resolve the issue to ensure your furnace operates smoothly and quietly.

7-Why is my furnace blowing cold air?

If your furnace is blowing cold air, it could be due to several different issues. Here are some common reasons:

Thermostat Settings:
- Incorrect Temperature Setting: Check the thermostat settings to ensure it's set to "Heat" and that the temperature is higher than the current room temperature. If the thermostat is set too low, the furnace may blow cold air.
- Fan Set to "On" Instead of "Auto": If the thermostat is set to "Fan On" instead of "Auto," the blower will run continuously, even when the furnace isn't actively heating. Make sure the thermostat is set to "Auto" so the fan only runs when heating is occurring.
Dirty Air Filter:
- A clogged or dirty air filter can restrict airflow, causing the furnace to overheat and then shut off temporarily. This can result in intermittent cold air blowing as the furnace cycles on and off. Change or clean the air filter to ensure proper airflow.
Pilot Light or Ignition Problems:
- If you have a gas furnace and the pilot light is out or the ignition system is faulty, the furnace may blow cold air instead of heat. In this case, the furnace can blow air without being able to heat it properly.
- Solution: For older models, try relighting the pilot light. For newer models with electronic ignition, a technician may need to inspect the system.
Flame Sensor Issue:
- The flame sensor detects whether the furnace has ignited. If it's dirty or malfunctioning, the furnace may blow cold air. It could be sensing that the furnace isn’t igniting properly and shutting the system off, leading to cold air blowing.
Blower Motor Running Without Heat:
- Sometimes, the blower motor may run but the furnace won't produce heat. This could be due to issues such as a malfunctioning gas valve, a faulty control board, or problems with the heat exchanger.
- Solution: A professional technician will need to inspect and repair the malfunctioning parts.
Tripped Limit Switch:
- The limit switch is a safety feature that prevents the furnace from overheating. If it’s faulty or tripped, it may prevent the furnace from producing heat, causing cold air to blow. A technician may need to reset or replace the limit switch.
Low or No Gas Supply:
- If your furnace is a gas model, it might be blowing cold air because there’s a problem with the gas supply. If there is a disruption in the gas line or the gas valve is closed, the furnace won't be able to produce heat. Check that the gas valve is open and contact your gas provider if you suspect an issue with the supply.
Ductwork Issues:
- Leaky or improperly insulated ductwork can allow heated air to escape, causing the air that’s blown into your home to feel cold. This can also cause uneven heating in your home.

If your furnace continues to blow cold air, it’s a good idea to contact Mannix Heating & Air Conditioning. Our team of experienced professionals can quickly identify the cause and ensure your furnace is working efficiently to keep your home warm and comfortable.
