Why is My HVAC Noisy? Tempe AC Maintenance

AC Repair in Tempe, AZ

Basements with furnaces and boilers or air conditioning systems can spring up and begin making noises that wouldn't be out of place in a horror movie. You may wonder where such noises come from and if they are dangerous or lead to something hazardous. Most are harmless annoyances, yet you should have your Tempe AC maintenance experts check your systems to be sure.


Furnace Sounds May Need Tempe AC Maintenance

Checking to see if your furnace makes a loud boom or bang is a must since a late ignition could be the cause. The minor gas explosion in your furnace room is caused by the burner failing to light, much like you may have encountered with a gas grill.

Why your furnace has an ignition delay? You'll find a couple of reasons.

  • High air-to-gas ratio.
  • Not enough gas, low gas pressure.
  • Your burners are dirty, worn out, or otherwise clogged.

It is essential to schedule Tempe AC Maintenance as soon as possible to have it cleaned and inspected. Wait for an HVAC professional to give the all-clear before turning your furnace back on.


Deep Rumbles

The oil that continues to burn in the combustion chamber after the burners shut off is the reason for loud house-shaking, rumbling throughout your house during one of the furnace's heating cycles. Rumbling can signal a problem with your burners, flame sensor, and pilot light.

Carbon monoxide (CO) gas release into your home could be necessary if you don't get professional furnace repair done.

Tempe AC Maintenance can make sure your system has no leaks, and you have sensors in the right places.

Another symptom of a carbon monoxide problem is leaks caused by a damaged heat exchanger. There is usually a rattling sound when the blower is engaged, and you need to get this fixed sooner rather than later.

Duct connections in your furnace might produce rattling if they are loose. You could fix this the DIY way by sealing your ductwork, or you could have a professional do the job. Rattling may come from loose panels that require tightening.

Clicking Noises

The furnace starts up with a clicking noise—the sound of your ignition clicking on. If your furnace or ventilation is clicking, then you have a problem with your flame sensor. Always have your flame sensor tested and cleaned. Besides this, your gas valve could leak, or you may have loose wiring.

Besides, clicking is the buzzing you may hear. The noise from your furnace may come from loose wires in the transformer. Over time, loose screws and other transformer parts might cause a buzzing sound. Call an HVAC technician to clean and service your furnace.

A clogged or filthy air filter can cause whistling as the restricted airflow causes the whistling sound. Always replace your furnace filter to help maintain airflow, enhance air quality, and eliminate that whistling sound.
