Furnace 101: The Exhaust Flue

Monday, March 10th, 2014

Today, we’ll look at one of the important components of a gas furnace that keeps dangerous fumes out of your house, while keeping the heat in: the exhaust flue. When you need repairs to keep your furnace functioning and safe, call Air Conditioning Experts, Inc. Since 1995, we’ve served Atlanta, GA with heating service of the highest caliber.

The Exhaust Flue

The brief basics of how a gas furnace works: A burner creates a high-temperature combustion gas, which then enters into a heat exchanger: a metal, clam-shaped chamber. The blower sends air across the outside of the heat exchanger, absorbing the heat from hot metal walls. The warmed air continues into the ductwork system.

When the combustion gas in the heat exchanger cools down, it changes into a liquid vapor. This is where the exhaust flue plays its part. The exhaust vapor is channeled from the heat exchanger to the exhaust flue, a lined metal pipe the runs from the furnace to the outside, usually to the roof since the heat of the exhaust naturally rises, where it dissipates harmlessly.

The exhaust flue must be kept in excellent shape so it does not leak carbon monoxide from holes, breaks, or corrosion. This is one reason why you must have professionals install your furnace: the flue needs to be carefully fit into position without leaks. It must also be the right size for the furnace, or else it can draw too much air and reduce efficiency.

If you notice any damage or corrosion on your exhaust flue where it exits from the furnace, or if you detect smoky odors from it, call for repairs immediately. A corroded flue usually must be replaced, but technicians can often safely patch up smaller holes with foil tape.

Never try to repair a gas furnace on your own…and never trust these repairs to amateurs, either. You need professionals skilled with maintaining and repairing gas-powered furnaces, which can be dangerous with inexperienced tampering. If you think there’s trouble with your exhaust flue, or any other component of your heating in Atlanta, GA, give us a call at Air Conditioning Experts, Inc. for 24-hour service.

Heating Repair Tip: What to Check if Your Furnace Isn’t Lighting

Monday, February 3rd, 2014

Some heating problems can be spotted early by homeowners: saving the technician the time and effort of hunting them down (and reducing the cost of the repair call in the bargain). One good heating repair tip entails what to check if your furnace isn’t lighting. There’s usually a single culprit and in some (but not all) cases, you can correct the issue yourself. For any heating repairs you need in Atlanta, give Air Conditioning Experts, Inc. a call!

If the furnace isn’t lighting, the issue usually stems from one of two components: the ignition (or pilot light in older furnaces) or the thermocouple. Both components are connected and indeed may even be part of a single larger component depending on the type of furnace you own. The thermocouple regulates the flow of gas into your furnace, while the pilot light/ignition ignites the gas itself to start the heating process.

Problems with the pilot light are usually the easiest to fix. You can check to ensure that the pilot light button has been pressed. In older furnaces, you may be able to re-light the pilot light yourself if it goes out. Most furnace models have instructions on lighting the pilot light; you should read them carefully before proceeding.

In other instances, however, you probably need to call in a professional. The thermocouple acts as a safety function. If the ignition system is damaged – or indeed if the thermocouple itself is damaged – then the flow of gas shuts off and your furnace won’t light. This is actually a good thing, since it keeps your home from flooding with gas. Unfortunately, correcting the problem requires the services of a trained technician, who needs to repair or replace the damaged component.

However, your furnace can also not light if it has  no power, or if your thermostat is malfunctioning and not calling for heat. Check to make sure your furnace has power and that your thermostat is set to the correct temperature before calling for repairs.

Thankfully, Air Conditioning Experts, Inc. is available 24 hours a day for heating repair in Atlanta, and we know what to check if your furnace isn’t lighting. More importantly, we can get your heater back up to speed again with your complete satisfaction in mind at all times.

When Is It Time to Replace My Furnace?

Monday, January 27th, 2014

It can be a tricky question: “when is it time to replace my furnace?” No one wants to consider the costs involved in buying a new furnace, but sooner or later the old one is just going to become too worn to continue functioning.  So when is it time to replace your furnace? A few tips can be found below:

  • Your furnace is very old.  This might not be a deal breaker, especially if your furnace has been well maintained. But old heaters usually have a lower AFUE (Annual Fuel Utilization Efficiency) rating, which means they’re not as efficient as newer models. They might not feature the kinds of bells and whistles you’d want either. And if your heater is experiencing additional problems, its age might be the determining factor.
  • Repair bills are climbing. Most appliances need a little repair every now and again. But if it seems like the technician is living in your door step and coming in every other day to fix the furnace, then the cost of a new unit may outweigh the inconveniences and mounting bills.
  • Your monthly bills are rising for no apparent reason. Wear and tear over the years can mean that your furnace is using much more energy to do the same job, which you’ll see reflected in your monthly bills. If your costs are going up even though you’re not using the furnace any more than normal, it may be time for a new unit.

If you’re asking “when is it time to replace my furnace?” then a little professional advice can come in handy. If you need heating service in Atlanta, call Air Conditioning Experts. We can discuss your options with you and either repair your existing unit or install a new one to better suit your needs. Give us a call today to schedule an appointment. You’ll be glad you did!

Why Is My Furnace Not Heating?

Monday, January 20th, 2014

Georgia enjoys mild winters, but that doesn’t mean we can escape without using our heating systems over the next few months, especially during the evenings. If you lose your heat in your home, it can mean an uncomfortable stretch until repair technicians can get out to you to solve the problem.

Furnaces are common ways of home heating in Atlanta, and are usually dependable machines (provided they receive regular maintenance). However, they can still suffer malfunctions that will prevent them from providing you with the warmth you need.

We’ve put together a list of reasons that your heater might have stopped giving you warm air. Make sure you call professionals, like those at Air Conditioning Experts, Inc., the moment you have trouble with your furnace. We can deliver the heating repair in Atlanta, GA that will make your home cozy once more.

Reasons your furnace isn’t heating

Loss of fuel source: If you have an electric furnace, make sure that it is connected to a power source. If you have a natural gas furnace, there may be blockage in the gas line, or a drop in gas pressure so that the burner isn’t receiving fuel. Don’t tamper with the gas line on your own, since it is potentially hazardous. Call for professional repairs.

Thermostat malfunction: You should always check your thermostat the moment you have heating (or air conditioning) trouble; the issue may be as simple as incorrect programming. However, the thermostat itself might have malfunctioned and lost its connection to the furnace, which will prevent the furnace from turning on.

Failed pilot/electric ignition: The pilot light is responsible for lighting the gas jets in many older furnaces. If the pilot light goes out, attempt to relight it. If that won’t work, than the burner unit might be too dirty for oxygen to reach the pilot. Newer furnaces use an electric ignition to start the burners, and this may have failed. In either case, leave the repairs to professionals, since this also deals with natural gas power.

Caution: Furnace at Work! (Or Not at Work)

We do not recommend that you open the cabinet of your furnace for any reason other than a visual inspection. Attempting to repair or even make minor adjustments to a furnace—particularly a gas furnace—can be dangerous to people without experience or the proper tools. If your furnace has stopped working, you need to call licensed professionals to diagnose the problem and find a remedy.

Air Conditioning Experts, Inc. knows that if your furnace shuts down, you will want service fast—no matter the time of the day or night. That’s why we offer 24-hour emergency service. For your long-term planning, look into our Comfort Club, which offers annual maintenance to keep your furnace running.
