The Benefits of Tankless Water Heater Installation

December 11th, 2014

Tankless water heaters have become a very popular option for homeowners of the last few years, and for good reasons. However, it’s important to understand how a tankless water heater works in order to see the differences between a traditional water heater and a tankless one. While each type is very capable of providing your home with hot water, a tankless water heater can provide you hot water as you need it, versus having hot water on standby. The process isn’t as complicated as it can sound, as we’ll explain below.

How a Tankless Water Heater Works

There are two types of tankless water heaters:

  • Point-of-use – small systems that typically mount underneath sinks, etc., to heat just that one outlet; point-of-use tankless water heaters are fueled by electricity.
  • Whole-home – larger systems that heat water for your entire home. These systems usually use gas or propane, but can also use electricity.

No matter which type of tankless water heater you use, the heating process is the same. Tankless water heaters use heat exchangers to heat the water on demand; the heat exchangers reside in the core of the tankless system. When you turn on the hot water tap of a tankless system, the water flow starts the heat exchanger; the heat exchanger generates heat that is then transferred to the flowing water. As the water circulates through the heat exchanger, it absorbs the generated heat, and the hot water starts to flow from your faucets. All tankless systems have a maximum pre-set temperature in order to avoid scalding.

Benefits of Tankless Water Heaters

  • Tankless water heaters can use up to 40% less energy than a standard tank water heater, which can reduce monthly utility bills.
  • Tankless water heaters have a longer life span than tank water heaters (10 to 13 years vs. 20 years).
  • Tankless water heaters take up far less space because they do not have a large tank attached to them.

If you are interested in the installation of a tankless water heater in your Plainfield property, take the time to schedule a time with an expert.

Will Radiant Heating Work for My Home?

December 4th, 2014

When most people think of radiant heating, they think of warm floors where you can walk barefoot, even in the middle of winter. This is true of radiant heating, but it’s only part of the picture. As with many types of heating systems, homeowners have choices with radiant heating, including how it’s installed and what type you of radiant heating you want. However, there is one consistency you should have with any radiant heating system: professional installation. The experts at DuAll Heating & Cooling have the training and expertise to install every kind of radiant system, so if you are considering a radiant system for your home, call us today!

Types of Radiant Heating

There are two ways that radiant heating heats: either via electric cables or hot water in durable PEX tubing. But there are a choices as to how it’s installed:

Electric Radiant Floor Heating

Electric radiant floor heating can be installed in 3 ways:

  • “Wet” installation – the electric cables are laid into wet cement; when the cement hardens, it acts as a radiant slab when the cables are electrified and heat.
  • Directly onto subflooring – the electric cables can be installed directly onto subflooring; the cable is usually installed in a specific pattern conducive to maximizing the heat.
  • In a mat – with a mat, the electric cable is woven into a mat of electrically-conductive plastic; the mat can be installed directly under flooring or directly to subflooring.

Hydronic Radiant Floor Heating

Hydronic radiant floor heating uses hot water or steam produced by a boiler to heat your home. The hot water is pushed through durable, flexible PEX tubing that is installed under flooring, directly to subflooring or installed via wet installation.

Radiant Panels

Not all radiant heating is installed underneath floors; you also have the option of choosing radiant panels. This type of radiant heating is installed behind walls and above ceilings. It can be electric or hydronic, but due to the possibility of leaking, electric is preferred. Radiant panels typically consist of aluminum for both electric and hydronic heating.

Will Radiant Heating Work for Me?

With the amount of choices you have available to heat your home with a radiant system, it is very likely that you can heat your home using a radiant system. However, the best way to determine this is to work with a trained expert. Call DuAll Heating & Cooling today and schedule an appointment to discuss your heating options in Romeoville.

Will Thanksgiving Turkey Really Make You Sleepy?

November 27th, 2014

We’ve all heard it before: you feel so sleepy after a Thanksgiving meal because of the main event: the turkey. For years, people have credited extraordinary levels of tryptophan in turkey as the reason we all feel the need to nap after the annual feast. But contrary to this popular mythology, tryptophan is probably not he largest responsible party for your post-meal exhaustion.

Tryptophan is an essential amino acid, which means it’s something that our bodies need but do not produce naturally. Your body uses tryptophan to help make vitamin B3 and serotonin, which is a neurotransmitter that sends chemicals to the brain to aid in sleep. But in order to get this essential amino acid, we have to eat foods that contain it.

Turkey has somewhat high levels of tryptophan, but so do many other foods, including eggs, peanuts, chocolate, nuts, bananas, and most other meats and dairy products. In fact, ounce-for-ounce cheddar cheese contains a greater amount of tryptophan than turkey. In order for tryptophan to make you feel sleepy, you would have to consume it in excessive amounts, and serotonin is usually only produced by tryptophan on an empty stomach.

The truth is, overeating is largely responsible for the “food coma” many people describe post-Thanksgiving. It takes a lot of energy for your body to process a large meal, and the average Thanksgiving plate contains about twice as many calories as is recommended for daily consumption. If anything, high levels of fat in the turkey cause sleepiness, as they require a lot of energy for your body to digest. Lots of carbohydrates, alcohol, and probably a bit of stress may also be some of the reasons it feels so satisfying to lay down on the couch after the meal and finally get a little bit of shut-eye.

If you feel the need to indulge in a heaping dose of tryptophan this year, go ahead! Turkey also contains healthy proteins and may even provide a boost for your immune system.

Here at DuAll Heating & Cooling, we hope your Thanksgiving is full of joy and contentment this year. Happy feasting!

What Types of Contaminants Can Hurt Your Indoor Air Quality?

November 17th, 2014

Many homeowners may think that the air quality in their homes is significantly better than outside. A house is sheltered, after all, and circulates its own air rather than taking it from outside. What may surprise them, then is the revelation that indoor air quality can actually be quite poor. There are a number of common indoor air contaminants that can provoke allergies, make you sick, and even prove fatal. Here is a list of the most common contaminants.

Animal/Insect Dander

If you have a cat or dog, you know about the absurd ability they have of shedding large amounts of hair all over the place. Along with hair, they also shed dander, which is comprised of groups of skin cells similar to dandruff. Dander causes strong allergic reactions in some people, and is actually the source of cat and dog allergies. This problem can be made worse by forced air heaters and air conditioners, which serve to propel the dander throughout the house.

Just like common house pets, insects shed dander as well. Insect dander is often small bits of exoskeleton, and provokes a similar allergic response when inhaled. Unlike pets, these insects often lurk in the ducts themselves, giving their dander a much wider reach when the A/C or heating is turned on.


Bacteria and viruses are also quite common airborne contaminants within a home. These microscopic organisms can survive and thrive in all sorts of unlikely places, including the ductwork of your home. Their most common form of entry, however, is often on or in a person that has been outside. When that person coughs or sneezes, the germs are scattered into the air and are able to infect others.

So, what are you supposed to do about these contaminants? Well, there are a number of air filters and purifiers on the market that are designed to remove these contaminants from the air. We recommend using one or more of them to improve the air quality in your home.

If you need to install an air purifier in your home, call DuAll Heating & Cooling. Our experts provide indoor air quality services throughout Naperville.

3 Signs that You May Need Commercial Heating System Replacement

November 10th, 2014

Winters in Illinois can be tough. For your commercial enterprise to thrive during this chilly time, you need to have an efficient and effecting heating system to maintain a comfortable indoor environment. Although regular maintenance and prompt repairs will help keep your business’ heating system operating, eventually an aging heater will reach a point where the best option is to retire it and have professionals install a new one.

Below are three warning signs of a commercial heater that is coming to the end of its life. If you suspect you may need commercial heating system replacement in Bollingbrook, IL soon, contact our specialists at DuAll Heating & Cooling right away. We will help determine if it’s time for a replacement and handle the installation work if it is.

3 ways to tell that you may need heating replacement

  1. Continually rising bills: A single spike in your company’s heating bills may indicate that the system requires repairs. But if the bills keep rising each month, and no amount of repairs or maintenance can stop it, you probably have a system that is too worn down from the decays of age. It is more cost-effective at this point to retire the heater and have a new, energy-efficient model replace it.
  2. Constant noisy operation: Is the sound from your heating system creating a disruption inside the work place? Loud operation is an almost certain sign that the heating system requires repairs, and if this has become the norm rather than the exception, you should consider having the whole system replaced. These sounds usually come from components that are too worn down to work well any more.
  3. High repair costs: Take a look at the bills for the repairs the heating system has needed over the last two years and tally them up against the cost of replacing the system. If the cost of any single repair is half the price of putting in a new heater, then it is costing you far too much to keep the system running. Call for heating technicians to examine the heater and give you a more definite answer about your best path going forward.

Our team of professionals stays up-to-date with the latest developments in commercial HVAC technology, so you will know that your new heating system is state-of-the-art. Put our experience to work for your company.

Why So Many Homeowners Are Choosing Radiant Heating Installation

November 3rd, 2014

Radiant heating is becoming more and more popular across the country. More new homes are being built with it, and more old homes are being upgraded with it. Homeowners by and large are flocking to this heating technology, but why? It isn’t exactly a new concept. Boiler-based radiator systems have been around for many decades. Why then, is radiant heating so popular right now? Read on to find out why so many homeowners are choosing radiant heating installation.

First: What is it?

Radiant heating is a term used for a specific kind of boiler based system that transmits heat through solid objects instead of air. This is accomplished by installing small water pipes in the subfloor and walls of every room to be heated. Occasionally, these pipes will terminate in an external radiator or baseboard heater. A boiler then heats and distributes water through these pipes, causing heat to radiate from them and into the room.


The first advantage is simple: radiant heating actually heats rooms better than forced air systems. Water is a much better conductor of thermal energy than air is, allowing it to transport more heat. The delivery system is also much more conducive to a comfortable heated room.

Warm air pumped into a room will rise to the top and fall as it cools. As most people dwell in the bottom portion of the room, most of the circulated air will not reach them until it is cooler. Radiant heating heats from the floor upwards, transmitting thermal energy from object to object. This heats the room much more evenly, keeping the majority of it in areas where the room’s occupants will feel it.

The next advantage is energy efficiency. Forced air systems tend to lose 20-30% of their heat, on average, to things like duct leakage. Radiant heating systems avoid that problem entirely by using a different delivery system. Radiant heat also tends to stick around for longer, keeping a room warm long after the system has been turned off.

If you’re thinking of installing a radiant heating system, call DuAll Heating & Cooling. We conduct radiant heating installation throughout the Romeoville area.

Reasons That Water Heater Replacement is Only a Job for Professionals

October 27th, 2014

A water heater that receives regular maintenance from professionals once a year and has any repair needs that come up attended to promptly can often last for over 20 years. But eventually, the stress of operation and general wear and tear from water and sediment in contact with metal over so many years will cause the heater to reach a point where it is too expensive to operate, or will no longer deliver you the amount of hot water your family needs.

When that happens, you should contact local skilled professionals with experience installing water heaters to replace your old system and put in a new one. DuAll Heating & Cooling has the training and tools to give you a great replacement for your water heater in Naperville, IL. Give us a call today if you’re ready for a fresh start with your water heater.

Yes… you do need professionals for this job

You may have had you water heater long enough that you won’t recall the type of work that went into installing it. Or perhaps you inherited the water heater with the house. Either way, you don’t want to find out how much labor and technical skill is required for this job the hard way: by attempting it yourself.

First, even before a single tool comes out to hook up the water tank to pipes, a water heater needs to be properly sized for a home. It’s important that the water heater can supply 1) a sufficient supply of hot water for your family’s needs, and 2) not waste energy doing it. It will require experienced professionals to determine the right sized heater for your needs, and you do not want to risk making the wrong choice.

When it comes to the actual work, there is a great risk from amateur installation of leaking pipes and poor soldering jobs. One of the most prominent reasons for later repairs on water heaters is shoddy initial installation work. You don’t want to live with a water heater that needs continual repair work and which leaks water everywhere.

It is especially important that you call for professionals if you use a gas-powered water heater, which is the most common type. (And for excellent reasons, and they are very cost-efficient to run.) In most locales, it is illegal to work on any system hooked to a gas main unless you are a licensed professional. You don’t want to take any risks of creating toxic and combustible gas leaks.

Water heater replacement is a simple and fast job when you call on experts like the team at DuAll Heating & Cooling. Water heater replacement is a job we handle often.

Don’t waste time and money on amateur work, and don’t risk you or your family’s health: call DuAll Heating & Cooling when it’s time for a new water heater in Naperville, IL.

New water heater efficiencies as of April 16, 2015

October 22nd, 2014

bulgingThe US National Appliance Conservation ACT (NAECA) will require water heaters to be more energy efficient beginning April 16, 2015.. What this means to you? You will be able to have existing water heaters installed past this date until existing supplies last. Manufacturers, however, will not be allowed to make or sell products that meet the new standard. How to prepare? Budget for higher cost water heaters or proactively replace older water heaters before that date. And if your water heater looks anything like this, then you have waited too long!!!

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

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.

If you are experiencing problems with your furnace, call DuAll Heating & Cooling today and schedule an appointment with one of our professionals.


When Is It Time for a New Boiler?

October 13th, 2014

Boilers are durable heaters that may last up to 15 years with proper maintenance. But if you wait until the last minute for replacement, you’re bound to have a mess on your hands, as you may only think to call for service after leaks damage your home, or you are left without any heating until replacement is finished.

This is why it’s important to be able to spot the signs that your old boiler is shot. The heating experts at DuAll Heating & Cooling have put together this list of a few of the ways you can tell it may be time for boiler replacement. Of course, every boiler is different, so always be sure to consult an expert before making a decision.

  • Old Age: If your boiler is approaching its expected lifespan, replacement is generally a good choice. Your older boiler has gotten a lot of use over the years, and, unfortunately, a breakdown is possible, especially if you seem to call for repairs frequently. In may be less expensive to replace your boiler now than to replace a broken system in the future.
  • Improper Size: Unfortunately, some contractors simply do not heed the proper sizing guidelines for boilers. Many choose larger boilers to ensure the customer gets adequate heat. But an oversized boiler will cost you more to run, using a lot of fuel and ultimately wearing down much sooner. If an oversized boiler causes you trouble, a new unit may be necessary sooner rather than later. A contractor should resize your new unit rather than replacing older components with similar ones.
  • Leaks: Leaks can indicate minor issues, such as a problem in the pressure valve, that simply mean your boiler needs minor adjustments or a couple of new components. However, leaks could also indicate corrosion or other damages that are beyond repairs. Calling for replacement is sometimes the only option when leaks are caused by rust and corrosion.

DuAll Heating & Cooling can help you decide whether you need boiler replacement in Bolingbrook. We can install, repair, or maintain any boiler model, so give us a call today!
