2 Important Reasons Why Your HVAC Technician Measures Draft

Thursday, October 26th, 2017

One of the most important aspects of your furnace is how it drafts. When air drafts properly from your gas furnace or gas water heater, spent oxygen and carbon monoxide go up a chimney or chimney pipe where it is dispersed outside your home. As most are aware, too much carbon monoxide in an enclosed area can have tragic results. The importance of proper drafting of a furnace can not be overstated for both operating efficiency and monitoring safe conditions.

How do we know, however, that a gas furnace has the appropriate draft pressure and draft intensity to operate efficiently and safely? It can be done using a furnace diagnostic tool called a draft gauge. A modern draft gauge is a digital device that helps a technician conduct a draft test, measuring aspects like draft pressure, draft intensity, backdrafting, and the percentage of oxygen and carbon monoxide. A draft test is a critical part of any furnace maintenance or tune-up.

How Does a Draft Gauge Work?

A differential pressure draft gauge measures the difference in the pressures of the air flowing inside a chimney or ductwork and that of the air on the outside. A draft gauge will not tell our technician what the specific cause of the draft issue is, only that there is some issue causing a draft pressure problem. The technician will then rely on his training, experience, and knowledge to discover the source of the draft problem.

Common Causes of Poor Drafting in a Furnace

A variety of causes can create poor drafting for a furnace. These can include extremes in indoor and outdoor temperatures, blockage of the vent pipe, loss of a vent or chimney cap, high winds, and others. This can cause poor ventilation or backdrafting, causing harmful gasses to spill back into the home.

While a slow or diminished draft can cause safety issues, excessive drafts can create inefficiencies in your furnace. If too much air is delivered to the burner fan, it can result in air leaking into the heating plant. This reduces the amount of CO2 and creates an increased stack temperature. This, in turn, results in poor efficiency of the furnace.

Why a Draft Gauge is often Used with a Combustion Analyzer

A draft gauge is often used with combustion analyzer so a technician can better determine the extent of the poor drafting and see its effect on the air in a room. Depending on the readings of the combustion analyzer, it can direct the technician to check on potential issues with the heat exchanger. It can also be an indication there may be a gas pressure issue or a combustion air problem. A high carbon monoxide parts-per-million reading on a combustion analyzer could also mean that a furnace is recirculating flue products and re-burning them in the heat exchanger. We’ve created a brief video on how a draft gauge and combustion analyzer work together as terrific furnace diagnostic tools in helping direct us to the heart of many furnace issues promptly. This saves us time and you money.

Monitoring Safe Conditions

Many Chicago area homeowners will schedule a fall furnace check-up or tune-up to head off potential maintenance issues in the winter and to ensure their furnace is operating at peak efficiency. Another important aspect of an annual furnace check-up, however, is that it monitors the safety of you and your family. It determines the quality of the draft of your furnace, making sure it is operating without putting harmful gasses back into your home.

If you have yet to have a furnace maintenance check this fall, we invite you to contact the well-trained, well-equipped team at Althoff Industries.

The #1 Way to Improve Air Flow in Your Home

Tuesday, October 17th, 2017

Many homeowners don’t fully appreciate the importance of airflow when it comes to the performance of their HVAC system and ultimately, the comfort of each room in your home. The fact is, if you have one room or many rooms that are less comfortable than others, it is quite possible it is an issue with airflow. Free airflow is disturbed by two basic forces friction and turbulence. What are some of the causes of poor or restrictive airflow in a home and how can it be improved? What is the #1 way to improve airflow in your home?

To find out the #1 way to improve airflow, we will first discuss 5 causes of poor airflow. At Althoff, our goal is always to get to the root of the problem first then provide solutions to improve comfort, function and performance of your equipment.

5 Causes of Poor Airflow

5. Duct Work That is Improperly Installed or Blocked

This happens more frequently than you may think. Improperly installed ductwork may not be sized properly or may even not be connected correctly. We have seen ductwork runs that seem to simply and mysteriously end! More common is ductwork that becomes blocked through the years by layers of dirt and dust or even foreign objects like clothing and toys. These improperly installed or blocked ducts create frictions that restrict proper airflow and will negatively affect the comfort of a room.

4. Lengthy Duct Runs and Those That Contain Too Many Turns

Some installers just expect too much from their HVAC, installing lengthy duct runs or duct runs that have too many turns. These turns create turbulence that doesn’t allow them to efficiently reach their desired destinations.

3. Too Few or too Small Return Air Vents

An efficiently installed and operating HVAC system with good airflow will both push air into a room and pull it out at the same rate. If too much air is being pushed into a room, it becomes slightly pressurized and uncomfortable. A frequent problem with rooms with poor air flow is that of having too few or too small return air vents.

2. Ducts That “Leak” Air

Over the course of the life of a structure, duct work can easily get holes or cracks from a combination of age, settling, and alterations to the structure. Duct work is often inadvertently punctured through nails. Like holes in a water hose, this leaking air can make the duct work and thus the furnace, much less effective in delivering treated air and in returning fresh air. It is estimated that nine out of ten homes have duct work that is leaking on some level. Depending on the number, size, and location of these holes, airflow can be dramatically negatively affected.

1. Dirty Air Filter 

While the above issues negatively affecting air flow in your home may take the assistance of a professional to properly correct, the simple, most effective way to improve air flow is to keep your air filter clean by performing regular air filter maintenance. Air filters are inexpensive and easy to change on your own. Ideally, they should be changed bi-monthly. If you have gone to a more restrictive air filter to get cleaner air in your home, it may be too restrictive for your HVAC system. If you have found some rooms becoming more uncomfortable, you may want to select a less restrictive filter. We’ve put together a brief video that helps explain why this is such an effective and simple idea to improve airflow in your home.

How Do You Define HVAC Contractor? This Definition Is Pretty Hard To Beat

The Althoff Definition of a Quality HVAC Technician

You probably have seen, read or heard advertisements from HVAC contractor companies in the greater Chicago area that talk about their “quality”. They’ll boast of the quality of their equipment, the quality of their service, and even the quality of the technicians they hire. Quality has become a word that is so overused in the service industry that it often loses its meaning. When it comes to HVAC, through the years, we’ve discovered there is a big difference in what they refer to as “quality”, and what our high standards are at Althoff Industries. Our definition of a quality HVAC technician reaches beyond most HVAC companies in the Crystal Lake IL area.

Treating Problems at the Core Cause

At Althoff Industries, our technicians are trained to find the core cause of a problem. They are not on a mission to “find” problems that may or may not exist. They are not there to sell you something. From the moment an Althoff team member answers your call to the moment we arrive  at your home, we are there to resolve your HVAC problem at its root cause, keep your family safe, and restore comfort to your home. They are there to offer logical options and let you make the final choice. They are often asked, “What would you do?”. In fairness, every family has different budget restraints. Our technicians are there to provide you HVAC options that are safe. The choice is ultimately yours, the way it should be. Don’t let an HVAC contractor sell you on a solution that may be their own best interest.

Why Finding the Core Cause is Important

Our technicians are trained to find the core cause of a problem because without that knowledge, technicians often just treat the symptoms. Our Althoff technicians are there to determine WHY a part failed and WHY your HVAC system isn’t performing properly. When an HVAC contractor tells you you need a new part, they should be able to tell you WHY the part failed. If they say “normal wear and tear” and your furnace is less than ten years old, it should raise red flags. If they can’t offer a logical reason for the part failure and you simply replace it,  you may just soon experience the same failure sometime in the near future.

Technicians, Training, and Tools

Want to hear something you may already know? Some HVAC people are more interested in selling you something than helping resolve your problem. Shocker right? At Althoff, we have a client-centered focus that compels us to determine your problem at its root cause and then offer you the best options to resolve it. No hidden agendas. We do this through good people who embrace our mission. They have families and understand the challenges of dealing with unexpected issues like HVAC maintenance problems. Next, we provide our HVAC technicians with superior training and exposure to the latest available techniques and technology. That technology includes innovative digital tools that can better determine exactly what is going on with your HVAC system. These tools accurately determine the underlying cause of your problem. We are not just guessing. We use precise instrumentation to verify how your system is performing. We know you expect more than an educated guess from a “quality” HVAC company. At Althoff Industries, we deliver.

Discover a Higher Definition of Quality at Althoff Industries

If you have been frustrated with an HVAC technician who “guesses” at your problem, or simply replaces a failed part without being able to tell you why it failed, contact Althoff Industries. Our service technicians are trained and have the latest tools to diagnose your HVAC problem efficiently and effectively. Best of all, they offer honest solutions that can best fit your family’s needs. Expect more and get more.

6 Items to Check Before Calling for Furnace Service

Wednesday, October 4th, 2017

At Althoff Industries, we make our living helping people keep their families safe and cozy with efficient operating HVAC systems. We have built our business and reputation by providing superior service that prevents and resolves issues, not creates them. It’s why many of our customers trust us for their annual furnace tune-ups in the fall. They know our extensive furnace tune-ups provide peace of mind. But furnace tune-up or not, problems can still occur.

Losing heat can be frustrating in winter weather but that frustration can be compounded when realizing, after the fact, that a problem was simple to resolve on your own. If you live in the Crystal Lake area of Northwest Chicago, before you call Althoff Industries or any HVAC company, here are six items you should check.

  1. Check the thermostat setting. Many families will reset thermostats when they leave for work or retire for the evening. Depending on your thermostat, it is possible a temperature setting gets accidentally way low or even takes the thermostat off of the “heat” setting. Before calling for furnace service, take a close look at your thermostat to make sure it is set properly.
  2. Make sure your furnace has power. Even if you use natural gas, your furnace is reliant on electricity. If that electricity is interrupted, you won’t have heat. It may just be that a circuit breaker got shut off for a variety of reasons. Check the circuit breaker for your furnace and reset it if it is in the “off” position. If it immediately pops off again, call a technician.
  3. Check your furnace filter. If rooms are not being heated properly, it could be because fresh air is not getting into the furnace. A common cause is a clogged or dirty air filter that is restricting air flow. Check your furnace’s air filter. You should be able to see through it when held up to a light. A common symptom of restricted air flow is when a furnace “short-cycles”, going on and off far too frequently to be efficient or to provide adequate heating.
  4. Check the pilot light. Gas furnaces have a small pilot light that should be constantly lit to provide an ignition source for the furnace. This pilot light is usually covered by a small door or metal plate near the base of the furnace, near the base of the base of the heating element. If this pilot light is out, you can try to relight it. This can be done by following the instructions on the on/off/pilot control on the furnace and using an extended barbecue grill type lighter or fireplace length match. Of course, if you have any hesitation about relighting your furnace, call a professional technician.
  5. Take note if your gas service has been interrupted. If your gas supply has been interrupted for any reason, the pilot light will need to be reignited. See tip number 4 above.
  6. Your blower motor may not be functioning. In some cases, furnaces may be producing heat, but that heat is not being dissipated through your home because the blower motor is not working properly. Stand by your furnace and when you hear it ignite, you should shortly hear the start of the electric blower motor. You should feel heat blowing from your vents. If you hear the furnace ignite but don’t hear the blower motor start or feel hot air from a vent, it is likely your blower motor. If you are an exceptional do-it-yourselfer, you may be able to replace the blower yourself. We, however, would suggest calling a professional.

A Few Final Tips Before Calling for Furnace Service in Crystal Lake

Winters can be tough in Crystal Lake and Chicagoland area but before you pay for a service call, take the above steps. You may be able to resolve the issue with a few simple checks. If the above steps are unsuccessful, write down the furnace brand name and model number along with the approximate age of your furnace and relay that to your service company. Let them know the steps you took and your results. This can expedite the service call, potentially saving you money.

If you experience a heating problem and need professional help, we invite you to call us at Althoff Industries. We have over 50 years of experience serving Northwest Chicago and have a highly trained staff of technicians with the latest technology to make sure your repair is done promptly and safely. When it comes to the comfort and safety of your family, trust the experts at Althoff Industries.
