My Furnace Is Making a “Boom!” Noise—Is This Dangerous?

Monday, November 15th, 2021

If you’re listening to your furnace for odd sounds, you’re already off to a good start when it comes to ensuring you have a heating system that runs safely and effectively. Gas furnaces have numerous safety features and aren’t normally dangerous for a household. (Let’s be honest: if they were, they would never be permitted into homes in the first place!) But malfunctions can happen, and the best way to prevent them from turning into potential safety issues for your household is to pick up early on warning signs and call for heating repair in Frederick, MD

So we’re glad you noticed this boom noise from your furnace and want to know more about it. We’ll get into details about this below, but remember that if you’re ever in doubt about anything regarding your furnace, it’s always safest to look to professionals for assistance.

The Cause of the Startling Noise

Nobody wants to hear a gas-burning appliance go “boom!” Just writing that sounds scary. If you’re near your furnace when it makes this sound, it can make you jump with alarm. 

What you’re hearing is the sudden combustion of a large amount of natural gas within the furnace’s combustion chamber. If you listen to the furnace coming on during normal operation, you’ll hear a small whoosh sound as it starts up: this is the same sound but on a smaller scale. The ignition system in the furnace ignites the gas from the burners, and as the flames consume oxygen to light, there’s a sound of air displacement. 

When this noise becomes louder to the point you worry about it, what’s occurring is a delay with igniting the burners. When the furnace is running normally, the igniter lights the burners soon after the gas valve opens to allow natural gas to flow into the burner assembly. If the igniter delays lighting the gas, a large amount of unburned gas will build up in the combustion chamber, and when it does ignite, the oxygen displacement is large enough to create a startling boom sound.

Is This Something to Concern You?

Yes. It may not pose an immediate danger, but it means a malfunction in the furnace’s start-up. Several different issues could cause this.

A common one is a failing electronic ignition system. These igniters often fail years before the furnace does and will need a replacement—this is a simple job for technicians. It could also be a failure in the control board, a more serious problem that can start to affect other parts of the furnace. A more serious possibility is a failing flame sensor. This device registers if the burners have ignited; if they don’t, it will shut off gas flow to prevent the build-up of unburned gas in the combustion chamber.

You don’t need to worry about finding out the cause yourself. Leave that to our team. We recommend you shut off the gas to the furnace, then call us to come check on the heating system and find out what parts need to be repaired or replaced.

If you’ve used the same furnace for at least a few years, you’ll have an idea how long it stays on each time it fires up to start a heating cycle. You may not pay special attention to it, but you’ll have a subconscious concept of how long it usually runs during a typical winter day.

Why Won’t the Furnace Evenly Heat the House?

Monday, January 25th, 2021
cold-man-and-woman-in-parkas

Your home’s central furnace is supposed to distribute heated air through ducts that spreads out to all the rooms connected with vents. This usually includes all the rooms with the exception of the attic, garage, or a few utility rooms. Although this spread of heat won’t be 100% even—there are always some variations because of the placement of rooms or lower amounts of insulation—you can expect your household to enjoy a relative level of comfort from the furnace.

Uneven heating, however, is a common problem that may affect a central furnace. If you have noticed some rooms are getting colder than they normally are, or maybe some rooms are getting too hot, something isn’t right. It may be a small problem or it could require you to call us for heating repair in Gaithersburg, MD to diagnose the problem and fix it.

What Might Cause Uneven Heating

Uneven heating can point toward several issues affecting the HVAC system:

  • Thermostat miscalibration: A thermostat picking up false readings may detect the house is warmer than it is, and will not keep the furnace running long enough to send sufficient heated air to all the rooms. You can’t push the thermostat higher to “fix” this, because it will cause rooms to become too hot. Technicians must recalibrate the thermostat.
  • Broken zone control system: Does your house have zoning for the HVAC system so you can shut off heating or cooling to some rooms and not others? If so, uneven heating might be due to a broken zone controls system—failed room thermostats, lost connections to certain rooms, or broken ductwork dampers.
  • Clogged air filter: A common cause of many household heating issues, a filter left in place too long will become congested and lower airflow. Less air will reach the distant rooms, causing uneven heating. Put in a clean filter to see if this improves the heating.
  • Leaking air ducts: Air leaks in the ductwork will affect the entire HVAC system, but most noticeably cause a drop in heating to specific rooms connected to a damaged stretch of ductwork. Only professionals can effectively locate these leaks and seal them or repair/replace the ducts. 
  • Short-cycling: When the furnace starts to short-cycle (starting and stopping repeatedly over a brief time), it won’t remain on long enough for an even heating spread. There are many reasons for short-cycling, and you’ll want a professional to find out the cause so it can be repaired.
  • Dying furnace: Uneven heating may be a warning that an older furnace (more than 15 years) is going into its final decline. We recommend calling for our technicians to give the furnace a thorough evaluation. They’ll tell you if it’s possible to go forward with repairs or if a replacement is a better choice.

No matter what is causing uneven heating across your house, you can trust our HVAC experts to have it solved. It’s our mission to provide high quality, efficient, and professional services that exceed customer expectations and surpass all others in the HVAC industry.

Why Won’t the Furnace Burners Ignite?

Monday, December 14th, 2020

You don’t have to know much about how your gas furnace runs other than the basics about an ignition system (either a standing pilot light or an electronic igniter) lighting the gas burner flames that generate the heat that in turn is blown into the ventilation system.

There may be a simple explanation, or you may need to call our technicians for heater repair in Bethesda, MD.

Not only is this usually ineffective, it can also be dangerous if you have a gas furnace and may be illegal in your jurisdiction.

If you go through all the troubleshooting steps we’ve listed below, which are all safe checks you can make to see if the problem with the furnace is simple, and still have the same problem, call us for professional heating repair in Germantown, MD.

Combustion Problems With High-Efficiency Furnaces

Monday, February 24th, 2020
gas-furnace

Modern furnace technology has allowed for heating systems with high efficiency that surpass anything built before. Where furnaces once averaged efficiency ratings of around 80% AFUE (meaning 80% of the fuel turns to heating energy and 20% escapes as exhaust), special high-efficiency condensing furnaces can score around 97% AFUE. This is because these high-efficiency furnaces are condensing furnaces. Condensing furnaces contain a second heat exchanger where the exhaust from the first heat exchanger is condensed to release even more heat.

Although a condensing furnace isn’t the ideal heating system for all homes and budgets, in the right home they’re a fantastic way to enjoy savings. But they can have some specific repair issues to watch for, specifically when it comes to combustion. We’ll look at a few of these combustion troubles below.
