Why Is My Furnace Blowing Cool Air?

Monday, December 11th, 2017

cold-manWe are certainly starting to feel cold temperatures hinting that winter is truly right around the corner now, aren’t we? With that in mind, most homeowners have already taken stock of their home heating systems, hopefully getting them tuned up for the season and scheduling repairs for any issues that may have popped up. Unfortunately, there is really no way to guarantee that you won’t run into any problems as the heating season progresses. You may just find that your furnace is not functioning properly at some point.

Now, certain problems with a furnace may manifest themselves with very subtle symptoms. Others, however, are quite obvious. It doesn’t take an HVAC expert to realize that a furnace blowing cool air is not one that is operating the way it should. It does require a professional heating technician to complete any necessary furnace repairs in Plainfield, IL,  though. If you notice that your furnace is blowing out air that is cooler than it should be, contact us to have the problem resolved promptly.

Why Is My Furnace Shutting Off and On So Rapidly?

Monday, October 10th, 2016

Chances are that you’ve run your furnace a bit already this year, if only to take the chill out of the air at night. Even if you’ve been resistant to using your heater and have instead opted to throw an extra comforter on the bed for the time being, you may have started up the furnace just to test it out. Whatever the case, if your furnace seemed to be running in short bursts, then you’ve probably got a problem on your hands.

The phenomenon of a furnace starting up, running briefly, and then shutting back down is known as short cycling. Short cycling can negatively affect your comfort and your heating system itself in a number of ways. If you notice this, or any other problem with your furnace in Bolingbrook, IL, contact a member of our team to have it resolved.

Plainfield Furnace Repair Guide: Is Your Home Not Getting Enough Heat?

Monday, October 20th, 2014

Is your heater working, but not quite as well as it should be? Is your heater not achieving the temperature set on your thermostat? A heating system that is working ok, but not great, most likely needs furnace repair in Plainfield. There can be a few reasons why your furnace isn’t producing the heat it should be, and it’s best to hire a professional to determine the reason why. At DuAll Heating & Cooling, our NATE-certified technicians can handle any heating issues you may have, so call us today.

Reasons for Reduced Heat

There are a few reasons you may experience reduced heating with your furnace:

  • Dirty air filter – dirty air filters can restrict air flow, which can decrease the volume of air flowing through your system, including the amount of warm air being delivered to your living spaces.
  • Faulty ductwork – your ductwork suffers wear and tear like any other part of your system. Cracks, holes and disconnections can create a great deal of air loss, which can result in less heating reaching your home.
  • Problems with the blower – the indoor fan that blows the hot air into your ductwork may be experiencing issues. A worn fan belt can decrease the amount of air flow, as can a problematic blower motor.
  • Imbalance in the system – there is a certain balance of pressure that needs to be maintained in order for your furnace to work correctly. Faulty ductwork can throw this balance off, making it hard to heat.
  • Blocked registers – make sure all vent registers are clear of debris, furniture or drapes as this can interrupt the flow of air.
  • Dirty burner – a burner that has a layer of dust and dirt can’t operate as it should, which may reduce its heating output.

Reduced heating can compromise your comfort and cost you money in extra energy usage. As you can see, there are a number of reasons why a furnace may have decreased levels of heating, which is why it’s important to hire an expert to inspect and make needed furnace repairs in Plainfield.

How Furnace Maintenance Can Prevent Furnace Repair

Friday, March 7th, 2014

Regular maintenance for a furnace is an essential part of taking care of your home’s heating. Unless your furnace receives an annual visit from a heating maintenance specialist, it will be prone to malfunctions and breakdowns, ultimately leading to poor performance, power drain, and a shorter service life. Regular maintenance will help prevent many unnecessary repairs.

Here are some of the ways that maintenance will reduce your needs for furnace repair in Romeoville, IL. To sign up for a great maintenance program today, call DuAll Heating & Cooling.

Ways Maintenance Will Prevent Furnace Problems That Need Repairs

  • Removing dirt from the burner: One of the key steps of maintenance on a furnace is cleaning it. And there’s no place more important to keep clean on a gas furnace than the burner where the gas jets ignite. If grime begins to coat the burner, the restriction of oxygen will make it difficult, even impossible, for the jets to turn on and create heat. Maintenance will take care of cleaning the burner unit at each visit to stop build-up.
  • Checking electrical problems: Electric furnaces need to have their wiring and circuitry checked to make sure the heating elements don’t fail during regular operation. Electrical checks are important for modern gas furnaces as well, since they use electronic ignition and electric safety devices.
  • Replacing cracked heat exchangers: If the heat exchangers in a gas furnace develop cracks due to corrosion, it can lead to dangerous situations where carbon monoxide leaks can enter the cabinet or your home. Maintenance technicians will catch heat exchangers that have cracked or are on the verge of cracking and replace them.
  • Testing airflow for air handler problems: During a maintenance check, a technician will measure the airflow from the vents to see that the air handler is working correctly. If it isn’t, the technician will see what issue needs to be addressed, such as replacing blower motors.

Make Sure You Have Maintenance

If you are looking to start a maintenance program to keep away furnace and other heating repairs in Romeoville, IL, or if you want to find a new one, contact DuAll Heating & Cooling. Our Maintenance Savings Plan not only brings you the tune-ups you need, but it also gives you a 10% discount on parts and labor, priority service, and a satisfaction guarantee.

What Could Possibly Go Wrong with My Furnace?

Friday, November 22nd, 2013

Today’s manufacturers of furnaces design them to meet stringent performance and safety standards. Compared to the furnaces of only 20 years ago, contemporary models have increased service lifespans and excellent energy efficiency.

However, no machine can work perfectly, so the electric or gas furnace in your home can still suffer from malfunctions and breakdowns that will require you call up a skilled technician. For excellent furnace repair in Naperville, IL, you’ll need the assistance of NATE-certified technicians like those on staff at DuAll Heating & Cooling.

Here are a few problems you may encounter with your furnace.

With proper maintenance and prompt repairs, you should have no difficulty overcoming these.

  • Broken blower motor fan belt: All furnaces use forced air sent through ducts to provide warmth. This requires powerful motors attached to fans. If the fan belt develops cracks and starts to loosen, it not only threatens the performance of the fan, it will damage other components in the cabinet. A loud clacking sound from the inside of the cabinet can indicate the need to replace the fan belt.
  • Failed heating elements: Electric-powered furnaces contain an array of heating elements that contain electric coils that heat up when current passes through them. The more heat the thermostat requests, the more elements turn off. An individual heating element can fail (losing its connection, burning out), which will mean a reduction in heating power. The element will need replacement.
  • Pilot light won’t come on: For gas-powered furnaces, a pilot light is the common way to light the burners in the combustion chamber. The pilot light can go out because of a strong draft, in which case it’s usually a simple task to re-light it. However, it may also go out because of loss of pressure in the gas line or from a dirt build-up along the burner, in which case you’ll need the assistance of HVAC specialists to fix the problem. Electric furnaces and some gas furnaces use an electric igniter instead of a pilot light, and these can also malfunction.
  • Cracks in the heat exchangers: The heat exchangers in a gas furnace transfer the high temperature combustion gas into the air. If cracks develop along the exchanger because of long use without maintenance, it can lead to a lead of toxic exhaust gasses—a serious health concern. If you notice black build-up on the furnaces internal components, rust, or an abnormal pilot light flame, shut off the gas to the furnace and contact a technician immediately.

Keep in mind that with regular maintenance—a yearly visit from an HVAC specialists to tune-up and clean your furnace—you should rarely run into any of the issues above. If you sign up for the Maintenance Savings Plan with DuAll Heating & Cooling, you’ll receive regular care, plus discounts on parts and any furnace repair work in Naperville, IL you need.
