Furnaces have been on the market for years that have full modulation of output capacity. Instead of two or three speeds, these furnaces can regulate their heat output to match the amount of heat that is escaping your home. They offer the ultimate in efficiency and comfort by never over heating your home, but instead just putting out the amount of heat needed at any given time. No waste is involved in this process and it makes a very comfortable environment to not turn on and off constantly.
A new air conditioner is in the design process that will perform the same way. Currently a/c units are both single speed and two speed and the two speed unit can even out temperature swings and slow down to provide the correct capacity needed depending on outdoor temperature. Two speed units run longer using less electricity and this longer run time can offer enhanced dehumidification and comfort. The new unit will have true modulating capacity where it’s cooling output will match the heat coming in your home from the outside. The unit will use a variable speed compressor to have infinite number of levels to keep your home the temperature you deserve. These units will remove moisture better than any regular a/c system due to their long run time which will extract more moisture.
When these units have been thoroughly tested and proven to be reliable, we will start offering these new machines. A couple of manufacturers have already released their units, but until I see them run trouble free for a number of years, I personally would wait for the kinks to be worked out, but they are thee future of air conditioning. I believe all a/c units some day soon will be of the full modulating type and comfort and efficiency will be unparallelled. By Dan Jape, Reliable Heating, Air, Plumbing and Electrical.

It is not often that a new product gets me so excited I want to write about it twice, but this is one of those times. A few months ago I wrote about a new remote access thermostat Trane had brought out that allowed a user to control their heating and cooling systems from any web enabled phone, I-pad or computer. The system is called Nexia Home Automation system and now that I have one actually installed on my unit, I wanted to go over it again, as I truly believe it is a very cost effective, easy to use “Smart House” device that many will find useful in their lives. If you enjoy tech, you will love this system. It is being expanded everyday to do provide more and more useful features.
First, it is a remote access thermostat that allows one to monitor and control the temperature and energy consumption in your home, business and second vacation home. If you are like me, it is hard to use a normal programmable thermostat because you are never sure when you will come home in the evening. With ComfortLink, you can simply adjust your cooling or heating when you start home to make sure it is comfortable when you arrive. I have in the past just left my home cool all day since I work in homes every day without cooling and want my home nice and cool when I arrive. ComfortLink will also send me a text message if something ever goes wrong with my heating or cooling which allows me to be proactive on getting it fixed early so I do not have to spend an evening without conditioned air. It will send text messages reminding me to change my filter also, which I find is something even I forget to do. (Remember the saying about the cobbler’s kids shoes?)I can keep track of energy usage and take action accordingly. I can control dehumidification with this system and have multiple fan settings and circulation modes that will allow constant fan operation without adding moisture during the summer. If you have a second home, you can periodically run the HVAC to keep it fresh and dehumidified.
Another nice feature is the ability to adjust lights, fans or small appliances from a remote location. This can be handy if you think you forgot to turn off the coffee maker or curling iron or if you want to simply turn on lights when away from home for security. Outdoor lighting or appliances can be controlled as can over 200 different compatible devices. The possibilities are almost limitless.Regular receptacles in your home or business can be installed so almost anything you desire will be controlled from anywhere in the world.
Door locks are easily installed that can be opened from your phone allowing a maid or service person easy, one-time access to your home without leaving a key. Then once in your home, you can watch what is taking place in all areas of your home by simply installing a Trane wireless camera that shows you real time how many teenagers are actually in your home after school and what your maid is really cleaning out. Never worry about your children getting locked out again, as you can simply give them a code to get in and your system will send you a text message when they arrive home after school. Without bothering them or causing them to think you are “checking in on them;” you can check in on them with the camera.
There is a simple walk around remote control device that is similar to a TV remote device that you can use in your home to control all these items if you just do not want to walk around and adjust all the lights etc. You can also turn off your cable box or satellite receiver during the day which, according to Clark Howard, can save you hundreds of dollars each year. You can turn it back on 10 minutes before you arrive and you won’t have to wait for your TV to boot back up.
These are just a few of the possibilities this system can bring you and Trane is constantly developing more and more uses for the Nexia system. It will soon control your home sprinkler system and all types of audio equipment. This is truly an exciting product that has only begun to scratch the surface of home automation and remote access that will surely be the standard in the future. Call Reliable Heating & Air today to get information about this product or arrange to have an in house demonstration. I think you will feel more connected to your most valuable asset, and enjoy features never available before in the world of “smart house technology”.

Cold weather is right around the corner and you will soon be in need of heat in your home. Furnaces need a complete service and cleaning each year before they are turned on to make sure they are safe and efficient. Many times, a homeowner will make the assumption that just because a furnace ignites, it is safe to operate. This could not be farther from the truth. Modern day furnaces are a very safe appliance and when maintained, can give years of service. But it is important that the series of safety devices and components that make them safe are in good working order. All modern day furnaces are safe if they are maintained properly, but if neglected could cause a problem. Reliable Heating, Air & Plumbing employees 100 plus Nate certified techs to make sure all is in good shape for a long cold winter.
One of the most important items to check and clean is the heat exchanger. A furnace burns gas and heats up a metal box that contains the gas burners and when the box is warm, a fan blows air across the outside of the box and transfer heat to the air stream, which is then distributed to all the rooms of a home. This heat exchanger heats and cools thousands of times a year and this causes expansion and contraction. This can cause metal fatigue and cracks in this burner box which allows carbon monoxide to leak into the air stream. We have long optical scopes that can be inserted into a heat exchanger to check for cracks and fatigue to make sure they are airtight. This is extremely important to be checked every year, as this piece is a very stressed component of the furnace and can fail at any time a furnace is over 10 to 12 years old. It is also very important that any rust and debris that accumulates in the heat exchanger is vacuumed out to allow all the heat generated by the combustion of the gas to be properly transferred to the air stream.
Another very important series of devices that need to be checked are high temperature limit switches which monitor a furnace for an overheated condition. These high limits are crucial in making a furnace safe and they need to be checked and tested each year to make sure they operate correctly. If a fan or blower stops operating on a furnace, the gas will continue to ignite until these limit devices sense the furnace is overheated and shut off the burners and turn the furnace off. These limit switches are directly in the air stream and take a lot of abuse and they fail after a number of years.
Furnaces have a device that moves air and fumes through the heat exchanger and it is often a component that needs service in a modern furnace. This “draft inducer” is in the combustion stream of the furnace and is exposed to the hot, acid laden fumes of the by-products of gas combustion. Some manufactures make the housing of these inducers out of plastic and they become so hot, the plastic housing cracks allowing flue gases to be emitted into the living space of a home. Some early models also used metal housings and fan blades that was not built out of corrosive resistant materials and they rusted out quickly. These units need to checked at the start of every season for proper operation and integrity of the housing. A complete and through inspection on all the controls on a furnace have to checked every year to assure one all is working properly on their gas furnace.
A gas furnace that a builder installs in your home can give you 14 to 18 years of service if they are taken care of properly and serviced regularly. A furnace that a consumer purchases can last 20+ years and provide safe efficient heat if properly maintained. Have your local heating and air contractor check for correct operation and your family should be warm and safe this winter. If you are need of a new furnace, they start out as low as $1495 and can go up to $3500 for a top of the line model.

When it’s finally time to replace your old heating and cooling system, there will be many choices and different decisions to be made that will affect your comfort, efficiency and overall happiness with any new system selected. It would benefit anyone to become familiar with the different components and terms you will face when that day does arrive.
There are 3 separate pieces of equipment you have to replace when purchasing a new HVAC system and they are the furnace, the indoor cooling coil, and the outdoor condenser or air conditioner. You have choices of different furnaces and condensers, but generally there is only one coil for any system.
There are many different manufacturers of furnaces and many different models available, but there are really just two distinctly different types of furnaces, single speed, single stage furnaces and two stage, variable speed furnaces. A single speed single stage furnace comes on full blast anytime it runs and the motor in it consumes $250 a year of A/C electricity. A two stage variable speed furnaces comes on gradually and only uses the amount of gas needed at any given time to heat your home and it’s blower consumes only $30 annually of D/C current. The Variable Speed furnace also comes with a special thermostat that actually allows the furnace to reduce the amount of humidity in your home by an additional 5 to 10%, and when it is drier in your home, you can actually keep it warmer and feel the same comfort level, which will save you money.
You have many choices in different outdoor condensers and what you pick is critical in your comfort. There are two different types of outdoor units, single speed units and two speed units. The two speed units are the best choice for most homes in the south, as they can be large enough in capacity to handle the extreme hot days, but because of their two speed design, they slow down to remove more moisture than a regular single speed condenser. The efficiency of these two speed units is usually so much better than a single speed unit that they can reduce the electric consumption by over 50% compared to your old cooling system you have in place now.
There are “builder grade units”, consumer grade units and top of the line units in both single speed and two speed. Builder grade units are units designed for a low, upfront price point and come with short warranties and will usually provide a shorter life span, as most builders are only interested in how a particular appliance operates for one year, which is the standard warranty a new home comes with.
Consumer grade units today come with a 10 year parts warranty and some companies offer a 10 year labor warranty or even a lifetime warranty if properly maintained. Units such as these can last 18 to 20 years often times and are available up to 16 seer in most cases.
Top of the line air conditioners are loaded with safeties and controls that allow them to last 20+ years and cut operating costs up to 60% while doing the best job in dehumidification and cooling and come in single speed, two speed single compressors, two speed twin compressors and even solar powered. Units such as these are more expensive up front, but are a better investment in the long run, by offering superior operation, efficiency and comfort.
It helps in any market place to know about the different products that are available and it is always a good idea to get at least 3 different estimates to see if there is a general consensus to what each company recommends.

Now that warm weather has arrived, it is very important that your cooling system is checked to make sure it is operating at peak efficiency. If your system is low on refrigerant or coils are dirty, it can cost you hundreds of dollars more each year to cool your home. Make sure you do not waste your money operating a cooling system that is not operating at peak efficiency.
Most HVAC companies offer a service contract which provides two visits a year to clean and tune up your heating and cooling systems and the summer inspection should include cleaning the outdoor unit of mud and debris lodged in the outdoor coil. This cleaning helps a unit give the best efficiency possible. It is always best to sign a service agreement with your company, as it gives your priority treatment during peak times and a discount on parts. At Reliable, we offer a lifetime warranty on most parts if a service agreement is put into effect at time of repair. If that same problem or part ever fails again, we fix it for free, no questions asked.
There are some big changes in the HVAC business brought about by the passage of the new Georgia State Energy Code, which goes in effect this year. It calls for some new tough policies regarding the heating and cooling systems that are installed in new homes.
Blower door tests are now required on all new homes to check the infiltration rate of a new home. The result must be less than 7 air changes per hour at 50 Pascals . Companies such as Reliable Heating & Air are required to have a DET certified specialist on staff to check the tightness of the duct systems and the thermal envelope of the structure. Duct leakage now has to be tested and certified to meet the new standard for tightness. Duct mastic has to be used to seal ducts to make sure they are tight and not leaking conditioned air.
Programmable thermostats are required with every system as are attic tents or covers over the attic staircases. Attic vent fans can no longer be installed in a new home unless they are solar powered. Electric furnaces cannot be installed in any new homes after January 1, 2011. A heat pump must be installed as the primary heat source if natural gas or propane is not used.
There are many other facets of this new energy code, but these are some of the highlights that might affect your HVAC system in the future.
For over 33 years, Reliable Heating & Air has been known as the company to trust for all your heating and cooling needs, providing top quality service at affordable prices. Many times, our customers have looked to us for referrals to handle their plumbing needs also since they have always felt a high level of trust and satisfaction from conducting business with Reliable. We have searched for many years for the right plumber who gave the same great service experience we like to provide our customers and have never been able to give a recommendation without worrying about the outcome. We are now proud to announce we have opened up a plumbing division offering the same great pricing and helpful cheerful service our customers have always had counted on for their heating and cooling needs and we guarantee 100% customer satisfaction. Call us today for any plumbing or heating and cooling needs.

To keep your house in top shape, give systems an annual checkup.
Spring cleaning is a tradition, but there are some other chores that should be part of your springtime routine, too. Most of them take only a few minutes, so get started!
1. Check your air-conditioning and heating equipment before the beginning of a new season.
2. Check and replace your furnace and air-conditioning filters every month. There are several types from which to choose, depending on your needs. Fiberglass filters last only one month, while the filters typically last three to four months. HEPA filters last up to six months and can be cleaned with a vacuum nozzle.
3. Most air conditioners have a drainage hole on the base of the cabinet, beneath the evaporator fins. This hole needs to be kept clear in order for the air conditioner to work properly. It’s a good idea each spring to use a paper clip or wire to poke through the hole and clear it.
4. To keep a dehumidifier working properly, remove its housing and let the unit dry completely. Vacuum every accessible surface and crevice.
5. Clean your bathroom fans once a year. Take the cover off, wash it in soapy water and clean dirt off the fan blades with a toothbrush. Be sure the power is off when you do this!
6. Check the flappers on your toilets at least once a year. If they are showing their age, replace them before they start leaking and wasting water.
7. Remove all faucet handles and clean their insides to keep the screws from corroding. Use a rust remover if necessary.
8. Replace the batteries in smoke and carbon-monoxide detectors twice a year: when the time changes to daylight savings time and then back to standard time. While you’re at it, dust or vacuum the detectors to keep them working at peak performance.
9. Make sure you have a fully charged fire extinguisher that you can reach quickly and easily.
10. Inspect and, if necessary, caulk around your home’s windows and doors annually. That will help keep out heat and humidity in the summer and cold drafts in the winter—and save money on your utility bills all year round.
11. Open and close all windows. Do they all open easily, yet close tightly? If not, check the weather stripping. There are a number of different types to consider.
12. The best time to caulk a joint outdoors is during the spring or fall. That’s when the width of the joint is halfway between its seasonal extremes. A plastic drinking straw or a length of plastic tubing makes a handy extension tube for caulking hard-to-reach places. Secure the extender with duct tape.
13. To really clear and clean screens for springtime, rub them with kerosene on both sides, then rinse with soap and water. Kerosene fumes are dangerous, so make sure to do this outside or in a well-ventilated area.
14. To fix a small hole in a window or door screen, dab clear household cement over the hole with a toothpick. If the screens are plastic, test the cement on a scrap to make sure it won’t melt the material.
15. Use the same technique to repair screen tears. Pull the two halves of the tear together and hold them in place with masking tape on one side. Apply the household cement to the tear, then smooth with a putty knife. When it’s dry, gently remove the tape and apply cement to the other side.
16. Clean out the gutters of winter debris and check them for damage from ice. Install gutter screens or protectors to help keep debris out of the gutters.
17. If a roof gutter is sagging, pitch it back to a level position by tightening its strap with pliers. The tighter the strap is twisted, the more the gutter will rise.
18. Be sure the gutters slope properly toward the down-spouts.
19. To prevent basement flooding, make sure there is at least three feet between the side of the house and the down-spout’s outlet. Use one of the following methods to reach that distance:
- Add an elbow for pipe and extension, although that often leaves the outlet still too close to the house.
- Use a splash guard that stretches about three feet.
- Attach a flexible extension hose to the end of the down-spout and bend it in away from the house.
20. To prevent foundation erosion as well as basement flooding, build up soil around the house and slope it away from the foundation.

There is an exciting new Trane product we have available that will allow you to put control of your home in the palm of your hand and provide total comfort and total security from any remote location. The “LiNK” system allows you to monitor and remotely control the temperatures and energy efficiency of your home as well as controlling the door locks, security lights and even turn on cameras that show you what is happening in your home. Many different systems in your home can be controlled from your web enabled phone or laptop computer. Two hundred and thirty-one different systems can be connected to the LiNK system and all you need is an internet connection.
Controlling and monitoring you homes heating and cooling system has many uses. I never know when I will get home on any given day, so a programmable thermostat is useless for my lifestyle. LiNK allow me to adjust my temperatures when I am on my way home so my comfort level is already where I like it before I get there. LiNK will send me an alert if my home gets too hot or too cold, possibly alerting me to a problem with my system.
One of the most exciting aspects of the LiNK system you will enjoy the most is the ability to have wireless camera’s pointed at your front door and throughout your home that will show you real time pictures of who just entered your home and what is actually taking place even though you might be out of town. The LiNk system can be programmed to allow select people in your home at certain times and not others and keep a 90 day record of when and who came in and out. This could be very useful for cleaning services, exterminators etc. It would also be very handy to know when your teenagers come home and who was with them. I will occasionally get a call from my security company that I had an alarm go off and I do not know if it was a false alarm or a real emergency. So far, thank goodness, all have been false alarms, but the drive home to check it out is a very tense trip I would rather not have to make. LiNK would allow you to verify to the police that you have had a real break in and need them to actually respond.
You can remotely turn off and on lighting and open and close your garage door in addition to many other uses. You can even program your system to work in concert when you arrive from work, push a button and the garage door will open, your entryways will light up, your security system will recognize you, and your front door will unlock. LiNK can have your favorite music playing for you when you get home and while you were away, LiNK can make sure the lawn sprinkler watered your lawn on schedule. If it had rained, you could have bypassed the sprinkler system from work.
The great thing about this system is it is modular and you can slowly but surely add new devices as you find you need them and as long as they are Z-Wave compatible devices, the sky is the limit. And the best part is the system is very affordable!
Call us today (770-594-9969) to learn more about this exciting new way of controlling your home.

Two years ago when the tax credit program started, December 31, 2010 seemed so far down the road it would never come. Well, here we are at the end of one of the best deals we have seen and there is only a few months left to take advantage of the $1500 credit that has allowed millions of homeowners to replace old inefficient heating and cooling systems. There have been many negative reports in the media about the stimulus plan and its success or failure has been debated to death by the press and talk radio, but the positive side of this bill is the impact it has had on every average homeowner who had old worn out heating and cooling systems that needed upgraded. These people have been able to purchase top of the line super high efficiency heating and cooling systems for the same price as an entry level system. A very nice added feature to these new systems is a special thermostat that not only controls temperature but also controls and removes more humidity than a regular system. The increased moisture removal makes one feel more comfortable at higher temperatures saving cooling dollars.
There are many new models and sizes available today that earn the tax credit and they give homeowners many more choices that were not open to them just a few months ago. Another positive side of this tax credit program is that all the different manufacturers of heating and cooling systems have advanced technology and efficiency to meet the government standards and these new models will be around for years after the credit program goes away in a few months. If you have not looked into the tax credit program, you should call your heating and cooling provider and at least explore this program as it ends December 31, 2010 and there is no extension or plans to extend this program, so do not miss this opportunity to cut your utility bills in half and increase your comfort by two fold.
The cold weather is here now and it is time to get your furnace checked for proper operation and safety. A properly adjusted furnace can save hundreds of dollars in cost of operation and make sure that your heating system is in top working order. Furnaces should be cleaned of rust and soot and have the heat exchanger inspected thoroughly each year. Gas pressure should be adjusted and the gas jets cleaned to assure proper operation and efficiency. Your air filter should be changed every 2 months and the blower wheel and assembly should be kept clean and free from dirt build up.
Another nice addition to your comfort system this season would be a central humidifier that adds moisture to your homes heating system. These units prevent damage to your homes hardwood floors, cabinets and furniture. They also prevent dry skin and static electricity and reduce the heating bills as it is more comfortable at a lower temperature when the moisture is increased. This is the opposite of the summer when comfort is increased with lower humidity. Call Dan Jape of Reliable Heating & Air at 770 594-9969 for all the details about the expiration of tax credits.

In the past two years, many homes in the Atlanta area have had new roofs installed due to the hail damage and storms that have hit us hard. With these new roofs came a very harmful side effect sold to the unsuspecting homeowner by roofing companies: a scorching hot attic. Most homes in Atlanta have a power assisted fan installed that exhausts hot air in the summer and keeps the temperature down in the attic which allows the air conditioning to work properly. The duct work in many homes is actually in the attic and by having proper ventilation, the air coming out of the vents can actually be 10 to 15 degrees cooler. Attics without these fans can approach 160 degrees in the middle of the afternoon.
The problem has come from the fact the majority of roofing companies have convinced the homeowner they no longer need power fans, instead replacing them with an inferior venting system called “ridge vents”. A ridge vent is simply a cap that goes over a hole cut along the peak of the roofing shingles. It is supposed to allow super heated air to naturally rise up and out the roof of your home through convection instead of using an electric fan to blow the air out of the roof. While some heat is exhausted, nowhere near as much is actually taken out of the attic when using a power fan and the result is a hot home and an air conditioner that has to run twice as long as it should under proper conditions. Also, the shingles can get too hot, shortening the life of the new roof. Roofers promote ridge vents because they have a high level of profit for the roofing companies, but this passive venting system does not do an adequate job for most homes in Atlanta. We see home after home that can’t cool to the level it used to before the change of the attic venting system. To make matters worse, there is much misinformation on the internet about attic ventilation which makes it more difficult to know what to believe.
There are power fans that mount in the gable vents already in the attic and there are also vents that need a hole cut through the roof and are usually mounted near the top or peak of the roof. These fans draw cooler air from under the overhang or soffit into the roof and blow up to 2000 cfm of air out when needed. They are controlled by thermostats mounted in the attics that turn the fans on at somewhere around 110 degrees. Critics of these fans complain they use too much electricity and the ridge vents do not, but time after time we have noted the temperature in the attic is 20 to 40 degrees warmer without power assisted fans. Whatever amount of electricity these fans do use will come back to you with lower cooling bills and reduced run time.
Do not let anyone convince you to change from power ventilation to passive ridge vents for any reason. If you already have, consider looking into changing back to power assisted fans, as it will bring you enhanced comfort, lower temperatures and reduced power bills for years to come.
