HVAC Care: Signs Your Furnace Needs Attention

Once the weather starts to turn cold, most families begin to rely on the furnace on a regular basis. If you notice any strange sounds or other problems preventing your furnace from operating properly, call a licensed HVAC technician immediately. You do not want to have issues with your furnace in the middle of winter season when you need heat the most.

The following are just a few signs your furnace needs immediate attention from a professional technician.

The Air Is Not Warm

When you turn on the furnace, your obvious expectation is that heat will come through the vents. If you have no heat when the furnace is on, the issues can range from very simple to complex.

Before you call the technician, check your electrical breaker box to ensure the breaker is on. You could have a faulty thermostat, which prevents the furnace from actually cycling on.

If your furnace operates on natural gas, make sure the pilot light is on and the gas valve is open. If either of these items are not open or lit, do not attempt to do so yourself. A professional HVAC technician is the best person to deal with natural gas HVAC issues.

Once you check all potential problems and cannot identify the issue, you need to get professional assistance.

You Hear Strange Noises

You never want to hear any strange sounds come from your furnace. A furnace is generally very quiet when running optimally. If you hear loud banging noises, they may signify a problem with the blower motor.

The fan may only need a simple adjustment, or the loud noises could mean there is a delay with the ignition switch. This is a problem which needs professional attention. In most cases, you need a new switch to rectify the problem.

You Smell Gas

Homeowners with furnaces powered with natural gas may notice faint smells of gas at different points. For instance, when you first turn your furnace on after a long season of non-use, you may smell a bit of natural gas. The smell should dissipate quickly after cycling.

If at any point you notice a strong scent of natural gas coming from your furnace at any other time, it means you likely have a leak. You need to get out of the house immediately and call the fire department and your gas company. A gas leak of any kind puts you at risk of an explosion.

Once contained, you will have to call in your HVAC technician to identify the cause of the leak and make the necessary repairs.

The Carbon Monoxide Detector Signals

All homes should have carbon monoxide detectors, as they are the only way to prevent carbon monoxide poisoning. Homes with gas appliances and furnaces must have detectors, as they will output carbon monoxide if they are not vented properly.

When the detector signals, you need to have many different technicians in your home to detect the problem. Someone from your gas company should come in and inspect for any leaks. An HVAC technician also needs to come test your furnace for a possible leak.

To clear your home of the carbon monoxide, you need to identify the source and repair it. Turn off the gas appliances and your furnace until you know for sure they are safe. Open your windows and run fans in all rooms of your home to clear the carbon monoxide. You may want to leave the house for a few days to be certain the levels are down.
