Heating & AC: Ductless Mini Split System Installation Process

Monday, March 18th, 2013

As spring and summer approach, homeowners throughout Bolingbrook, IL are looking for ways to be more energy-efficient, to improve the indoor air quality of their home, and to be eco-friendly. More and more homes are making the switch to ductless mini splits not only for these reasons, but also because they enjoy the flexibility and minimal disruption of ductless installation. Whether you’re in the market for an air conditioning system for your new home, or thinking about switching from conventional central air, you need to know about the installation process. For more information about ductless mini split systems in Bolingbrook, IL, call DuAll Heating & Cooling today!

Let’s take a look at some of the basics of the ductless mini split system installation process:

  • No ducts. This is perhaps the greatest advantage to going ductless, and therefore greatly distinguishes ductless from ducted systems. Retrofitted ductwork can involve demolition and renovation of your home, as even flexible ducts have to be snaked through your walls and in the attic. Ductless systems, on the other hand, generally need only one small hole for the conduit to pass through the exterior of the home and to connect to the outdoor unit, which can placed as far away as 50 feet, depending on the model and particular home setup.
  • Air handler. The ductless indoor air handler is a sleek, attractive, and compact device that sits high on a wall or suspended from the ceiling. You can usually install about 4 air handlers to one single compressor/condenser unit. These can be placed around the house to create cooling zones, each with its own thermostat. The air handler is nearly silent and can also be operated by remote control. It extracts hot air as well as circulates cool air much more efficiently than duct extraction.
  • Outdoor unit. The outdoor unit of is not unlike its counterpart in a conventional central air. It houses the compressor, which is the engine that pumps the pressurized refrigerant through the refrigerant cycle. The condenser coils are also located there, where the heat from your home dissipates.

The ductless installation process is straightforward and relatively unobtrusive, but it needs to be done professionally to ensure that you get the most out of your cooling for years to come. For ductless mini split installation in Bolingbrook, IL, call DuAll Heating & Cooling today!

3 Common Air Conditioning Repair Services

Monday, February 25th, 2013

Keeping your home comfortable is likely a big priority for you. Summer is right around the corner and many homeowners are anxious to start using their air conditioning system again. But if your air conditioning system isn’t working well then the inside of your home might be just as hot and humid as it is outside. DuAll Heating and Cooling provides complete air conditioning repair in Naperville, IL. We know how important it is for you to stay cool in your home which is why we put together this quick list of some of the most common AC repair that we see.

Common Air Conditioning Repairs

With all the use that your air conditioning system gets throughout the year it will eventually need repairs. At DuAll Heating and Cooling we offer fast and friendly air conditioning repair in Naperville, IL. These are 3 of the most common air conditioning problems that our technicians run into.

AC Not Providing Enough Cooling

If your air conditioning system isn’t providing you with enough cooling then you have a real problem. This is often caused by a clogged air filter but can also be caused by low refrigerant. While both of those are easy fixes for your technician, it might also be that your compressor isn’t working or that the fan motor is broken. Call your Naperville, IL air conditioning repair company if you’re not getting enough cooling in your home.

Air Conditioner Making Strange Noises

If your air conditioning system has started to make new or unusual noises it likely means that you need repairs. Common AC noises are hissing, gurgling and squealing. Hissing usually indicates that you have a refrigerant leak or that your compressor is leaking air. Gurgling might mean that you have low refrigerant and squealing is often caused by a bad fan belt.

Clogged Air Conditioning Air Filter

The air filter for your AC system is there to keep dirt, dust and other contaminants out of the moving parts. If it isn’t changed regularly it can get clogged and cause big problems. It can cause your air conditioning system to have to work harder to cool your home. It can also cause you to not get enough cooling in your home.

Contact DuAll Heating and Cooling for all your air conditioning repair in Naperville, IL.

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!

Commercial HVAC Tip: Advantages of a Commercial Rooftop Unit for My Building

Monday, January 21st, 2013

If you own a business in Bolingbrook, you’re likely very interested in making sure that the climate inside your building is always perfect. Keeping your business properly heated or cooled is critical to your success. There are many different types of commercial HVAC systems available. At DuAll Heating and Cooling, we’ve worked with businesses of all types in Bolingbrook helping them with their HVAC needs. We thought it would be helpful if we put together some of the advantages that rooftop units have.

Commercial Rooftop Unit Efficiency

Commercial rooftop HVAC systems in Bolingbrook generally have a very high rate of efficiency. This allows business owners heat and cool their business without breaking their bank. If you have a heating and air conditioning system that is costing you a lot of money, you may not be able to run it as often as you should to keep your customers, tenants or employees happy. This can cost your business or lower productivity.

Space Savings

Often, the square-footage inside of businesses is a premium. You want to make sure that you have enough space inside your building to be able to run your business well. The HVAC systems that are required to heat and cool your business are very large. Keeping them on the roof is a great way to save space on the ground and inside your business. This allows you to use that extra space for storage, offices or whatever else you need.

Rooftop Commercial HVAC System Durability

Some of our customers are skeptical of the durability of commercial HVAC system. However, like residential heating and air conditioning products, they have a lifespan of 15 to 20 years. This allows them to provide plenty of heating and cooling for your business.

Benefits of Commercial Rooftop HVAC System Maintenance

When you own a business, you want to make sure that every aspect of it is working well. Having a professional Bolingbrook commercial HVAC maintenance technician look over and repair your HVAC system regularly is a great way to make sure that your business’s climate stays the way you want it to.

For all your Bolingbrook Commercial HVAC services, make sure you contact DuAll.

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!
