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.

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!

What You Need to Know About Adding Central Air Conditioning to Existing Homes

Monday, August 13th, 2012

There are a number of factors to consider when looking at upgrading or adding central air conditioning to your Bolingbrook home.  These range from the air conditioner type, to its energy-efficiency ratings, the necessary AC capacity and proper AC sizing, as well as the fact that a ductwork system will be needed for it to function.  All of these are items which our skilled AC technicians can help you understand.

Central air conditioners are very energy-efficient providing anywhere from 15% to 30% more efficiency than those that are ten to twenty years old.  This is because every AC goes through rigorous testing and receives its own SEER rating which shows how energy-efficient it actually is comparable to others on the market.  A central AC unit is usually placed in an inconspicuous place such as outdoors in the backyard or in a garage or basement.  Central air conditioning systems are very quiet and easy to use.

As air conditioning contractors we will perform a heat-gain calculation that will determine how many BTUs the air conditioner needs to be in order to properly cool your space.  Things which get taken into account during this determination include square footage of the space, how much shade or sun is present throughout the home, whether insulation is present in the exterior walls of the home, as well as window and door placement.  These are all put together to calculate the AC capacity which is necessary to give you a properly sized air conditioner.

When looking at a central air conditioning system one of the biggest factors will likely be whether there is already an existing duct system which can be utilized, if it is in good shape, or if it needs to be repaired or replaced.  If there is no duct system then many central air conditioning systems require that a duct system be installed.  There are also other options such as ductless systems.

DuAll Heating and Cooling has experienced air conditioning technicians in Bolingbrook who understand the various factors associated with adding or upgrading to a central air conditioning system, and can walk you through the process of deciding whether it is the correct AC system for your specific needs.  Contact DuAll Heating and Cooling today!

Air Conditioning Guide: Common Ductless AC Repairs

Monday, July 16th, 2012

All major home appliances and HVAC components will need repairs at some point. That is simply a fact of life that all homeowners should come to accept. One thing that helps for peace of mind when dealing with a certain repair job is to have an idea how common it is. That can help you settle the question of whether your Romeoville ductless air conditioner is a having a lot of trouble or just needs some routine repairs.

To answer that very question, here are three common repairs that ductless AC systems often need.

 #1: Leak Repair

Refrigerant leaks can spring up just about anywhere in a ductless AC: the condenser coil, the evaporator coil, the refrigerant line… While premature leaks are sometimes the sign of improper installation or neglecting maintenance duties, sometimes leaks just happen over time. Leaks will affect performance, but are easy for a Romeoville AC professional to fix and are generally not anything to worry about, as long as they are not a frequently recurring issue.

 #2: Charging Refrigerant

Frequently going hand in hand with common repair #1, refrigerant charging is a very common repair for a number of noticeable ductless AC issues. Even if there isn’t a noticeable leak, sometimes the refrigerant may need to be recharged anyway on account of poor installation or an improper charge in the past. Like all air conditioners, ductless systems need a certain level of refrigerant in order to operate properly, so recharging refrigerant when necessary is an important common repair.

 #3: Fixing Drainage Problems

A ductless air conditioner that is failing to properly drain the condensed moisture that has been extracted from the air can be a real annoyance. Especially in humid climates, these drainage issues cause problems. Often, the repairs are as simple as unclogging a drainage tube or replacing the pump motor. These are common problems and repairs, so they are not anything to worry about as long as they are handled professionally and in a timely manner.

There are other potential repair issues that you may run into with your ductless AC system, but these are among the most common repairs that technicians have to make. When in doubt about an issue with your Romeoville air conditioner, call DuAll Heating & Cooling to troubleshoot and fix the problem.

Ductless Air Conditioning Installation Steps

Monday, July 2nd, 2012

If you are ready to install a ductless air conditioning system in your Bolingbrook home or office, call DuAll Heating and Cooling. There are plenty of do-it-yourself jobs around the house, but a ductless system installation is not one of them. Our team of trained professionals will make sure that everything is done correctly, and we’ll keep you informed throughout the process installation process. In fact, we thought we’d start right now. Here is a walkthrough of the work involved when professionally and safely installing a ductless system.

Outside

Like window units and centralized systems, the louder components of a ductless air system are kept outside. We set up your condenser on a flat, hard surface, making sure it stays where we put it. Casings are generally waterproof, but elevating the components a few inches is ideal. We will keep your condenser an appropriate distance from your house, eliminating any noise. When our professionals install your system, you’ll forget that your condenser is even out there. DuAll wants you to enjoy your new cooling system without being kept up at night.

Inside

Ductless mini split systems feature indoor, wall mounted units that disperse the conditioned air. This allows you to create temperate zones, heating or cooling only those rooms you want to, only as much as you want to. Most manufacturers recommend positioning the indoor unit high up on your wall, approaching the ceiling. Cold air circulates throughout the room from top to bottom. When we install your blowers we make sure that all measurements are accurate and that your units fit in your walls perfectly.

And in Between

This would be the tricky part, but our AC team in the Bolingbrook area has the experience and training necessary to handle all steps of the installation process. A hole, about 3 inches in diameter, is drilled in your wall. Copper tubing and refrigerant lines connect the indoor and outdoor components, and a condensation line keeps the humidity out of your home. Now the mounting plate is installed and the mechanical components are connected. Your new system will be up and running in no time.

Remember that many areas require the work of a licensed plumber or electrician for this installation. Letting the Bolingbrook air conditioning professionals here at DuAll install your system will ensure that your warranty is not voided and your system is installed right.
