What’s the Difference Between Central Air Conditioning and a Heat Pump?

Monday, August 19th, 2013

One of the great luxuries that homeowners enjoy today is the wide selection of cooling systems available for installation in their homes. There is no need to feel as though you have to stick with what you know. As energy prices continue to rise, more and more homeowners are looking for more efficient, effective ways in which to cool their homes. If you are interested in exploring your air conditioning options, contact the Bolingbrook, IL air conditioning professionals at DuAll Heating & Cooling. We have many different air conditioning systems for you to choose from, and we can help you determine which is best for your home. Here is some information to consider about what sets a heat pump apart from central AC systems.

Here Are the Differences Between Central AC and Heat Pumps

Heat pumps and central air conditioning systems are actually very similar in many ways. Both feature an outdoor condenser unit, and both use a ductwork system to distribute cooled air throughout your home. The big difference between the two is the way in which they work to cool that air. Traditional split central air conditioners rely on the consumption of fuel in order to cool air. Heat pumps, on the other hand, utilize the heat transfer process. It is this innovative operation that allows them to operate so efficiently.

By transferring ambient heat out of your home (as well as back in when the heating season arrives), a heat pump is able to cool down your house while consuming just a small amount of electricity. The less energy your air conditioning system consumes, the less money you have to spend to operate that system. This means that you can cool your home more affordably and in a more environmentally friendly way. Contact a member of our team today if you are interested in learning more about the benefits of cooling your home with a heat pump.

Stop paying too much money to cool your home down. Schedule a heat pump or air conditioning installation with the Bolingbrook, IL air conditioning professionals at DuAll Heating & Cooling. No matter how you decide to cool your home, we can help you do so in the most efficient and reliable way possible.

Why Does My AC Keep Making a Rattling Sound?

Thursday, August 15th, 2013

Your AC system has a lot of moving parts that can break down and cause problems for your home’s comfort. Often, your air conditioning system will start to make a new noise when it needs service. Rattling is a common issue that we get called to fix and we wanted to share some of the likely causes for this problem.

Give us a call here at DuAll Heating and Cooling if you need any Naperville, IL AC services.

Naperville, IL AC Services: AC Making Rattling Noises

If your AC is rattling, call us here at DuAll Heating and Cooling for Naperville, IL AC services. Here are a few of the possible causes:

Fan cage – Your air conditioning system has two fans: one inside and one outside. The cages around them protect you and also protect the fan from any injury or damage. But if the cage becomes damaged, it can rub against the fan and cause a rattling noise. If this is the case, make sure that you turn off your AC right away in order to avoid bending your fan’s blades.
Motor – The actual fan motor can become damaged and start to make a grinding or rattling noise. Sometimes it’s just that the motor needs to be lubricated or the bearings replaced.
Debris – If any branches or twigs get into your air conditioning fan it can cause it to rattle against the blades. This can also cause damage to your fan blades which could require that you replace them.
Loose parts – Your air conditioning system has a lot of moving parts it in that can come loose and start rattling. The only problem is that to find the loose part you will have to take off the panel for your air conditioning system and poke around inside. Doing that is usually unadvisable and should only be done by a professional air conditioning contractor.

We know that when your air conditioning system starts to make any new noises that it can be extremely frustrating, and even uncomfortable when guests are around. That’s why we work so hard to respond quickly and provide you with the quality of service that you deserve.

If you need any Naperville, IL AC services just call the specialists at DuAll Heating & Cooling.

Air Conditioning Repair Tip: Common AC Noises and What They Mean

Monday, February 18th, 2013

DuAll Heating & Cooling provides air conditioning repairs in Naperville, IL and the surrounding towns. We offer comprehensive air conditioning repairs and maintenance services for all types of AC systems. Is your air conditioner or heat pump making a loud noise? While all AC systems make some noise, they shouldn’t make excessively loud or unusual noises. For this week’s blog post, we’ve put together a list of some common AC noises and whether or not they are cause for concern. Call us if you need an air conditioning repair.

Noises Made by Heat Pump Reversing Valve

Your heat pump has a reversing valve that reverses the flow of refrigerant when the system switches from heating to cooling, or vice versa. You may hear a type of whooshing sound immediately after it does this, but it should only last for a few seconds. If it lasts longer than that, or if your heat pump is not switching tasks properly, then call a repair technician.

Compressor Noises

Some compressors make loud noises when they turn on, especially on older units. This noise can be described as a buzzing sound, which is created by the reversing valve coil. Noise from the vibration of the compressor is another common noise, but this is nothing to be concerned about.

Fan Blade Noises

If you hear loud noises that sound like metal knocking against metal, this can be created when the fan blades hit against each other, ice, or even refrigerant tubing. Turn off your heat pump if you hear this clanking noise. If you don’t, the cause of the issue can damage the fan, compressor, and eventually the motor. If the blades are hitting the refrigerant tube, it can cause a refrigerant leak, which can cause a number of serious problems. Grinding or squealing noises may also be caused by something wrong with the fan blade.

If you hear any unusual or loud noises while running your AC system, call the Naperville IL air conditioning technicians at DuAll Heating & Cooling after you shut off your system. Contact DuAll Heating & Cooling today!

Air Conditioning Question: Reasons My AC is Not Cooling Well

Monday, September 24th, 2012

If your air conditioner is not working properly, there are a number of possible things that might be the root of the problem. Today we are going to take a look at some of these possible issues and what you can do about them, or if they are severe enough, when you should call a Naperville Air Conditioning professional for an inspection.

* Thermostat – The thermostat could be set too high or it could simply be improperly set. Check the setting first and then lower it to a temperature well below what you need, such as 65 degrees. If the system still does not turn on or cool properly, it is likely an issue with the air conditioner.

* Dirty Evaporator Coils – Next, check your evaporator coils. If they become too dirty or have debris on or around them, this can keep the refrigerant from cooling properly and cause problems with your air conditioner’s efficiency.

* Undersized Unit – If your system never quite cooled your home properly, it may be undersized. A load calculation can determine if this is the case.

* Blocked Condenser Unit – Check outside to determine if any debris or other things have built up around your condenser. Blocked air flow or vents can cause a number of problems, including reduced cooling in your home.

* Bad Compressor – While this is hopefully the last possibility, it is still possible. A bad compressor can lead to a slew of issues and eventually your system will simply stop working. If you have checked everything else and cannot find the problem, call a technician to inspect your condenser unit and compressor.

* Low Refrigerant – If refrigerant gets low, often your system will stop cooling at all. There is likely a leak somewhere that should be inspected before the system is turned back on again. Only a professional should ever recharge or repair a refrigerant leak.

If any of these problems occurs and you are unsure what to do next, make sure you call a professional that has been fully trained in identifying and responding to such issues. The fastest and most effective way to ensure your home’s air conditioner gets back up and running properly is to call in a pro.

Air Conditioning Tip: Types of Repairs Ductless Mini Splits Might Need

Monday, September 17th, 2012

A ductless mini split air conditioning system is no different from a traditional central air conditioner in many ways. The types of repairs you might face during routine operation of your air conditioner are a prime example as any number of issues might develop that you need to deal with. Here are a few and how you should handle them.

Clogged Filters

Each of your satellite units and the outdoor condenser has a filter in it that needs to be cleaned or changed on a regular basis. If any of them gets clogged it can lead to that unit freezing over due to blocked air flow. Freeze ups are not as common in ductless systems but can happen and the result is messy and uncomfortable.

Inoperable Satellite Unit

A ductless system has more components than a traditional central air system. If you have multiple satellite units inside, you can have between 3 and 9 total devices that need to be serviced. So, a single satellite unit is just as important as any other. If one stops working for any reason, it’s possible that it is a standalone problem, but it could also be a systemic problem so the entire system should be inspected. Contact DuAll Heating & Cooling to schedule an inspection today. Our cooling experts have been a trusted provider of air conditioning services in Bolingbrook for over 20 years.

Electrical Issues

If your ductless mini split system starts short cycling, the cooling is suddenly inefficient or you hear any strange buzzing or smell burning wiring from the condenser, you should have a professional inspect your entire system immediately. Circuit breaker flips are also a problem if they occur repeatedly.

Refrigeration Line Problems

Each indoor unit has a refrigeration line stretching back to the condenser. While these lines are designed to withstand extreme weather conditions and are usually protected during installation, damage can occur. If you notice or suspect damage to any refrigerant lines, turn off your system and call for professional service immediately.

Call DuAll Heating & Cooling today, our Bolingbrook air conditioning technicians are experts in air conditioning installation and repair.

Air Conditioning Tip: How to Get the Most Out of Your Zone Control AC System

Tuesday, September 4th, 2012

A zone control system is an energy saving upgrade for your Plainfield home’s air conditioner that can save you quite a bit of money on your cooling bills. But it is important that you use the system to its fullest to ensure you get the most you can out of it.

To start, you should ensure that your zones are well defined. Zone control systems allow multiple thermostats to be installed throughout your home, but those zones should be designated carefully to match your household usage patterns. For example, a single zone can be set for upstairs bedrooms that are generally empty for the same period of time each day. However, you might want separate zones for your living room and kitchen – where you spend time equally but are doing different things and therefore have different cooling needs.

Most zone control systems have digital thermostats, meaning you can program them carefully to turn on and off at certain times of the day. You can turn your upstairs cooling off automatically at 8am every day after everyone leaves for school and work, and then leave it off for a few hours after everyone gets home until just before bed time. Simultaneously, you can lock the thermostat in places that are rarely occupied like your attic or basement. You may want cooling available in these spaces, but it isn’t worthwhile to spend the money to have them cooled regularly.

A good zone control system should be used to supply cooling to those rooms that need it only when necessary. So, make sure you and your family understand exactly when the air conditioner should be on and which thermostats can be used and when. If used properly, such a system can reduce your cooling bill significantly each year without sacrificing anyone’s comfort.

Air Conditioning Question: What is a Rooftop Unit?

Monday, August 27th, 2012

Rooftop units tend to be used in commercial buildings for both air conditioning and heating purposes. As light commercial HVAC specialists in Bolingbrook, DuAll Heating & Cooling works with rooftop units for a variety of businesses in the area, so call us today if you are interested in installation or repair.

Rooftop units are specially designed heating and air conditioning systems that are placed on the rooftops of commercial structures. They both cool and heat larger buildings such as retail storefronts, office spaces, strip malls, and even warehouses. Rooftop units can include a wide selection of special features such as high-end filtration systems, humidifiers and dehumidifiers, and even the option of solar panels for a much higher level of energy-efficiency.

Commercial rooftop air conditioning and heating units are usually housed in one cabinet that conditions the cooled or heated air. An air handler then pushes that air through an intricate series of ducts which are usually run between floors, or behind walls. As the air moves at a uniform speed and is well-balanced throughout the ducts, each room with a vent will receive the proper amount of air that has been preset by the HVAC thermostat.

Rooftop units are designed to be dependable, working all year long to make the various indoor workspaces comfortable to be in. They can provide cooled and heated air with one single unit, but there are also separate rooftop AC and rooftop heating units that are then connected to the same ventilation and ductwork system.

DuAll Heating & Cooling is a light commercial HVAC company in Bolingbrook that understands the intricacies of rooftop units and can help you through rooftop AC installation, repair or maintenance. Contact DuAll Heating and Cooling today!

Heating and Cooling Tip: Save Energy and Money While on Vacation

Monday, August 20th, 2012

When you’re on vacation you don’t want to have any worries about your Naperville home. There are plenty of steps you can take to ensure that your comfort systems and appliances are not eating up energy when you’re out of the house. DuAll Heating and Cooling has some easy tips to save energy and money during your vacation.

Air Conditioning and Heating: Turn your air conditioner off or use a programmable thermostat with a vacation mode. There’s no reason to keep the house as cool when there’s no one home. If you’re away in the winter set your heating system to 60 degrees: this will keep your pipes from freezing.

Water Heater: Because having hot water is not a concern when no one is around to use it, water heaters can either be shut off completely at the breaker switch, set to “pilot”, or turned down to the lowest temperature setting.

Appliances and Electronics: Unplug TV and entertainment systems; they still draw power when plugged in even while turned off. Unplug computers that have instant-on features, toasters, coffee pots and any other devices that can leech energy.

Refrigerator and Freezer: If completely empty, clean and unplug the refrigerator and freezer.

Water: Shut water off at the main water line valve and drain faucets to prevent water leaks or pipes bursting while away.

Lights: Shut off all lights except for those on timers that will turn on and off automatically at preset times of day. Hook up exterior floodlights to motion sensors that will shut off after a certain amount of time.

By following these simple steps you can save energy and save money while on vacation. For more tips on how to more effectively use your Naperville heating and cooling system, give DuAll Heating & Cooling a call today!
