Safety Components in a Modern Gas Furnace

Friday, January 2nd, 2015

Today’s gas furnaces are safer than ever, with advanced features and settings that won’t allow for electrical danger, gas leaks, or fire hazards as long as the unit is properly installed and maintained by professional gas furnace service technicians. The technology used in furnaces has been around for a long time, but installation once came along with a lot of stress for homeowners looking to protect their homes and families. Of course, the design improved over time, and today’s models contain key safety components and devices so that you can have some peace of mind about your home comfort system.

One benefit of modern furnaces is that they do not have a standing pilot. This means that a pilot light does not need to stay on at all times; it only needs to be on for the length of time that the heating cycle must run to heat the entire space. This is an improvement for efficiency and because a pilot light that is left on at all times can increase the risk of danger. Three of the other innovations that make modern furnaces so safe are described below.

  1. Fan and Limit Switch: Sometimes, the fan switch and the limit switch in a furnace are separated while other times the two switches come packaged as one. In any case, the fan switch controls when the blower motor turns on and off, while the limit switch keeps the furnace from overheating. When the temperature in the plenum that connects the air handler to the ducts becomes too high, the gas valve is shut.
  2. Flame Detector: The flame sensor is a probe that simply detects whether or not there is a flame. When there is no flame present, gas can leak into the home, but the sensor instead sends a signal to the control board to activate a safety lockout that prevents gas from flowing.
  3. Air Pressure Switch: The air pressure switch ensures gas is venting properly via the draft inducer. The draft inducer is meant to assist combustion gases in safely venting away from the home, but if airflow becomes reduced for any reason, the air pressure switch shuts off the gas.

The heating professionals at Air Conditioning Experts, Inc. offer thorough gas furnace service in Duluth, GA for installation, repair, and maintenance, and can answer all of your questions about furnace safety. Give us a call!

Types of Insulation Services Your Home May Need

Wednesday, August 20th, 2014

Good insulation in your home is key for keeping both your heating and cooling energy efficient. When your home lacks insulation, you’ll not only feel it with a lack of comfort, but you’ll see it in the form of high energy bills. Thanks to advances in the industry, there are several different types of insulation available for your home, but not all will be a perfect fit for your needs. Today we’re going to discuss the two types of insulation Air Conditioning Experts, Inc., carries, with a particular focus on blown-in insulation in Duluth.

Two Types of Insulation: Spray Foam and Blown-In

Two types of insulation in which we specialize are spray foam and blown-in. Both offer great benefits, but blown-in insulation is better for retrofitting.

Spray foam insulation has become very popular, and with good reason. Spray foam is insulation, but it is also an adhesive, so once it attaches to something, the bond is permanent.  It is extremely efficient, has good R-values and can reach cracks, crevices and nooks that are hard to insulate with larger, less flexible options. However, spray foam expands considerably when it hits oxygen – typically up to 100 times its size – so not only does it take care and knowledge to work with, it can be a little more difficult to use in a retro-fit situation.

Blown-in insulation, also known as loose-fill, is a mixture of small particles. These particles are typically made of fiber, fiberglass, foam, cellulose and mineral wool. All these materials are created from recycled waste, making blown-in insulation a very green option. Blown-in insulation is injected into the pre-existing walls of your home with a specialized hose via small holes that have been drilled between studs. Once the insulation of one wall is complete, the technician will move on to the next wall. Holes are re-covered with the original drilled-out circle reinstated as part of the wall; some wood glue and paint restore the wall back to normal.

Blown-in insulation can fill in crevices and nooks that aren’t reachable or easily insulated, but will not cover quite as tightly as foam insulation.

Good Insulation = Comfort and Efficiency

Insulation helps stop the transfer of heat, which is important year-round. Is your insulation keeping you cool in summer and warm in the winter? If not, it may be time to consider blown-in insulation in Duluth.

Air Conditioning Question 2: Why Go Ductless?

Monday, June 17th, 2013

If you’re in the market for a new AC, then you have a staggering range of options available to you, from conventional central air and heat pumps to ductless mini split, geothermal, and solar air conditioning systems. With the exception of the ductless mini split, all of these systems use extensive ductwork in the walls, ceilings, and floors of your home to remove and distribute air. But, while ductwork has become a standard feature of homes that need cooling solutions, that’s no longer necessary with the latest developments in ductless technology. There are some good reasons to consider going ductless. For air conditioning services in Atlanta, call Air Conditioning Experts today!

  • Energy efficiency: Ductwork can account for up to 30% energy loss in your home. That’s a substantial volume of cool air that you’re paying for. Even with duct sealing and routine cleaning, they can still suffer loss when they move through uninsulated spaces of your home, like the attic or a crawlspace. Ductless mini split systems are highly efficient, with SEER ratings of up to 27, making them some of the most energy efficient air conditioners on the market today, mainly because the air handlers sit directly in the living space, typically up to four units per outdoor compressor/condenser.
  • Zone Control: Because of their design, ductless mini split air conditioners offer you an unprecedented amount of control over your cooling. If you’re frustrated at the thought of cooling the kitchen while everyone sleeps upstairs, then you’re probably looking for a way to customize each zone of your living space. Perhaps your kids like their room at 75 °F, but you enjoy a 70 °F. This is no longer a problem. This will not only improve your comfort, but also increase the energy efficiency of your home.
  • Air quality: If you’re bothered by allergens every cooling season, or by the amount of dust that can collect in ductwork, then consider going ductless to improve the air quality of your home. Sleep, compact air handlers have a built-in air filter to distribute cool air directly into your living space, without it having to pass through dusty ductwork.

Speak to your local AC technician to see if a ductless air conditioning sysem is right for your home. For more information about air conditioning in Atlanta, contact Air Conditioning Experts today!

What Are Common Problems With Central AC?

Monday, May 13th, 2013

We rely on our Atlanta, GA air conditioners every day to provide cool air throughout the long hot summer. Considering all that wear and tear, it’s no wonder that such a complex system should develop some problems over the course of its service lifespan. In this post, we’d like to address some of these problems so that you know what to look out for. While professional installation and routine maintenance are important to ensure that successful continued operation, sometimes repairs are inevitable. For air conditioning repair in Atlanta, GA, call Air Conditioning Experts today!

  • Inadequate cooling: If your AC doesn’t work as nearly as well as it once did, or its cooling ability is unable to meet your needs, then there are many possible causes for this problem. Check your air filter to make sure that it is not dirty or clogged with dust and debris. If not, then there may be a problem with your thermostat. It may need to be recalibrated so that it triggering your AC when you need it.
  • AC won’t start: If your AC won’t start, it could be either electrical or a thermostat problem. Check to see if your thermostat is calling for cool air, and adjust accordingly. If that doesn’t work, it may not be communicating with your air handler. Also, there is the possibility of an electrical fault within your power supply; perhaps a damaged wire. Electricity can be hazardous so make sure that you hire a certified professional to perform any repairs.
  • Low refrigerant: Like all air conditioners and heat pumps, your central AC relies on the refrigerant cycle to cool your indoor living space. The refrigerant pumped by your compressor through the system of coils needs to be of a certain level—that’s known as its “charge.” If your system is low on refrigerant, then your system will not operate properly.

This list is by no means exhaustive. For more information about central AC, or to schedule air conditioning repair in Atlanta, call Air Conditioning Experts today!

Air Conditioning Tip 1: Improving Ductwork Improves Energy Efficiency

Monday, April 8th, 2013

You rely on your forced air heating and cooling systems throughout the year. The efficiency and effectiveness of these systems in turn rely on the integrity of the ductwork running behind the walls, underneath the floorboards and in the ceilings above you. If these are impaired in any way, the results can be damaging to the quality and comfort of your indoor air as well as to your wallet. When the time comes to improve your ductwork in your Atlanta home, call a ductwork technician at Air Conditioning Experts.

There are a variety of different reasons to improve the ductwork in your home. Here are just a few:

  • Energy loss- If your heated or cooled air is obstructed or inhibited in any way as it travels from your heater or air conditioner to the interior of your home, then it is costing you money. Energy loss is common in forced air systems, but it can be exacerbated by problems in your ductwork. Sealing up cracks, repairing leaks and other improvements can significantly improve the energy efficiency of your home.
  • Flooding- When water vapor cools in your ductwork, it can condense and leave behind small areas of standing water. This can create rust and can affect the integrity of your ducts in addition to becoming a breeding ground for microbial allergens.

There are still other reasons why improving your ductwork may be necessary. The ductwork in your home may have been installed incorrectly, for example. If your ducts were not installed by a certified and trained technician, then there is possibility that they are not working correctly. Furthermore, the components of your ductwork can become loose over time, opening themselves up for dirt, dust and debris. Ductwork can also be damaged during the construction of other projects in your home.

Energy efficiency and value go together. Making sure your ductwork is in solid working condition means improving the cost effectiveness of your home energy use. It also improves air quality and the comfort of your home. Don’t let poor ductwork get in your way. Call the Air Conditioning Experts in Atlanta today.

Atlanta Geothermal Guide: Types of Geothermal Loop Systems

Monday, March 4th, 2013

A geothermal heating and cooling system is a great home comfort option for those homeowners in Atlanta looking to reduce both energy costs and their environmental impact. Geothermal heating and cooling systems use a heat pump in order to keep your home comfortable year round in a very efficient, effective manner. In fact, geothermal systems are often more versatile and reliable than standard types of heat pumps.

This is due to the fact that they draw the heat they utilize from the ground or beneath water on your property, where temperatures are more constant. They are able to do this by using a geothermal loop system. Here is some information about the types of geothermal loop systems that may be used during your geothermal heating and cooling system installation. Call Air Conditioning experts for more information.

Closed Loop Systems

Most geothermal systems will use a closed loop system to circulate an antifreeze solution through the ground or in a body of water on your property. This solution is not used up or disposed of, but rather cycled throughout the closed loop system again and again. This type of loop system may be installed vertically or horizontally.

Horizontal installations are the most common type. They also require a certain amount of usable space on your property, though. Pipes are buried next to one another at staggered depths, and the antifreeze solution is piped through via the loop system, gathering heat. If there is not sufficient space the loops may be tightly coiled, allowing for an installation in smaller amounts of land. However, this runs the risk of overdrawing heat from the ground around the system

Open Loop Systems

In an open loop system water itself is used in place of an antifreeze solution. Once the cycle is completed the water is simply discharged from the system. Obviously this type of installation requires the availability of sufficient water on your property. A trained professional will help you determine if an open loop system is right for your home.

If you have any questions about geothermal heating and cooling system installations or the types of loop systems you may use, call Air Conditioning Experts. We are the geothermal professionals in the Atlanta area. Our technicians can help you heat and cool your home more efficiently and effectively with a geothermal heating and cooling system installation, so call today.

Heat Pump Question 1: What is a Heat Pump and How Does it Work?

Monday, February 18th, 2013

If you are looking for a highly efficient, environmentally friendly way to both heat and cool your Atlanta home, a heat pump may be the best choice for you. Heat pumps have grown in popularity over the years, and more and more homeowners are taking advantage the quality performance and energy savings they offer. Here is some basic information about heat pumps for you consider. If this sounds like a home comfort system option you are interested in, contact Air Conditioning Experts for more information.

Unlike traditional home heating and air conditioning systems, a heat pump does not consume a fuel source in order to create heat or to cool down your home. Heat pumps work on the same basic principle, regardless of what type of heat pump you are using. This is the principle of heat transfer.

Heat pumps are so efficient because they use just a small amount of electricity to transfer existing heat into or out of your home. By transferring readily available heat they are able to greatly reduce the amount of energy it takes to maintain comfortable temperatures in your home. Heat can be taken from the environment surrounding your home in the winter and transferred inside to warm it up. When it is hot inside the heat pump’s operation can be reversed to remove the unwanted heat from your home.

While all heat pumps use the same basic heat transfer process there are a few ways in which they gather the energy needed to maintain comfortable indoor temperatures. The most common heat pump models are air-source heat pumps. As the name suggests, they draw heat from the air for use in your home. Geothermal heat pump systems, on the other hand, draw heat from the ground around your home or are submerged in a water source on your property and take heat from there.

There are a lot of factors that must be considered before deciding to use a heat pump in your Atlanta home. The environment around your living space, land availability and the demand you put on your heating and cooling system must all be considered. Only a trained professional can help decide if a heat pump is the right heating and air conditioning option for you, so call Air Conditioning Experts for the advice you need to make the best decision for your comfort.

Common Heat Pump Problems in Atlanta

Monday, January 28th, 2013

Heat pumps are renowned for their environmentally friendly heating and cooling performance as well as the incredible efficiency with which they operate. As is the case with any other heating and air conditioning system, of course, regular maintenance and a professional installation are necessary to ensure the high-quality, uninterrupted performance of your heat pump. You can get all the exceptional heat pump services you need in Atlanta simply by calling Air Conditioning Experts.

Of course any mechanical system is susceptible to wear and tear or damage. At some point you will need to schedule repair service for your heat pump. Here are some examples of the more common heat pump problems we face here in Atlanta.

  • Poor Temperature Maintenance – There are a lot of reasons why your heat pump may have trouble maintaining target temperatures, and they vary in degrees of seriousness. Sometimes it is as simple as incorrect settings at the thermostat. Anytime you are dealing with a system that both heats and cools it is possible to switch to the wrong function. This is definitely a best possible case scenario. There also may be a problem with your ductwork or the blower responsible for air dispersal.
  • Ice Building Up on Evaporator Coils – As with most heat pump problems, the development of ice on your evaporator coils can have many different causes. The most popular is insufficient refrigerant levels. This may indicate a leak, as refrigerant is recycled over and over in your heat pump system, not consumed, meaning levels should not really change. It is possible that some refrigerant was lost during service, but frequently frozen coils should certainly be inspected by a professional.
  • Cold or Hot Spots Developing – It is impossible to be really comfortable if different areas of your home are all different temperatures. Even heating is integral not only to comfort but to heating and cooling efficiency as well. This is most likely a ductwork problem, though a simple cause may be behind the uneven heating. Make sure that your furniture is not blocking air vents or registers. Your heat pump system will heat and cool your home a lot more effectively without having to force air through a sofa.

Occasional problems with your heating and cooling system are unavoidable. Keep them as infrequent as possible by scheduling high-quality, professional service. Call Air Conditioning Experts for all your heat pump needs in Atlanta.
