Spring Cleanup List Begins with HVAC

Monday, April 18th, 2011

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.

Big Savings Available Now!

Friday, April 15th, 2011

by Dan Jape of Reliable Heating & Air

This is an exciting time to be in the market for a new HVAC system  in the greater Atlanta area due to the many programs and specials available to help with the cost of replacing an old inefficient system.

The tax credit program is still available for homeowners and it is $500 as a straight bottom line credit off your income taxes. It is called the 25C program and it is available to most taxpayers without any income limits. You simply have to purchase a high efficiency furnace and air conditioner or heat pump and you can earn this lucrative credit. The $500 tax credit will pay for some of the upgrade costs needed to qualify for this great program.

There is money available from all the major EMC electric companies to finance a new heating and cooling systems and it is in the form of a 36 month no interest loan that can make the payments very affordable on a new comfort system that can save hundreds of dollars in energy bills every year. They also have very low interest loans for people who need long term payments.

The Atlanta Gas Light company has a number of specials that are available to almost anyone in the Atlanta area that has gas at their home. There are a number of different gas marketers, but they all buy their gas from Atlanta Gas Light Company. There are a few cities that have their own gas companies such as City of Austell or Sugar Hill that do not participate in the gas promotions, but the vast majority of Atlanta homeowners can take advantage of these specials. If in doubt if you qualify, call our office and we can help you. If you replace a furnace and an air conditioner and use an 80% efficient furnace, you can earn a $200 cash rebate and if you purchase a 90% furnace and an a/c unit, you can earn a $400 cash back rebate. If you currently have a heat pump or a dual fuel system with a gas furnace or a heat pump, you can earn a $1000 cash rebate if you replace the gas furnace and air conditioner or if you just replace the gas furnace and have the heat pump rewired to work as an a/c unit. This is a very lucrative program and this money will go a long way in helping with the cost of a new HVAC system replacement.

Trane also has incentives of $200, $400 and $1000 dollars or interest free financing for 36 months. All you have to do is purchase a high efficiency heating cooling system and the rebate is an instant rebate given at the time of time of purchase.

If you have not had your existing system serviced for the summer, now is the time. If your unit’s coils are not clean or if your units are slightly low on refrigerant, it can cost hundreds of dollars in wasted energy bills. A dirty blower wheel and any number of items out of sync can come back to haunt you in higher bills and poor comfort. People who have their routine service performed are assured they are getting their monies worth when the long hot summer days arrive with a vengeance. Call Dan Jape today at 770 594-9969 for details on this new tax credit program and take advantage of all the utility incentives available to help pay for a new energy efficient Trane Comfort System.

Don’t forget the ducts

Wednesday, December 8th, 2010

By Dan Jape – Reliable Heating & Air

One of the most important aspects of your home’s heating and cooling system is the duct work. Proper duct work can make a huge difference in the comfort and efficiency of your home. I visit four or five customer’s homes each day and in the vast majority of them, I find duct work issues that need to be corrected to make sure the new heating and cooling system we install will deliver what is promised in terms of comfort and efficiency. I see a number of customers who simply are talked into replacing the equipment in their home without analyzing the distribution system and they end up with the same poor comfort level they had before they purchased a new system.

One of the most frequent problems we find is lack of the proper amount of return or intake duct work. A proper operating system has to have the correct amount of return ducts to match the output of the system. Without the correct amount of intakes, many problems will arise such as lack of cooling capacity, overheating furnace heat exchangers, freezing cooling coils and reduced life of the entire system. Many homes suffer this issue and it must be corrected when upgrading your HVAC system.
Many homes have duct work built out of fiberglass or duct board. This a foil covered, glue impregnated sheet of fiberglass that is used as plenums or distribution boxes on the top and the sides of furnaces and is a very poor choice for ducting material. It is very porous and rough inside and collects dirt and debris and after a few years of service is always filthy dirty. Mold grows on the inside of this material and it is very hard to keep the corners and seams sealed up to keep air from leaking out in attics or basements. Metal ducts and plenums need to be installed to replace this inferior product when a new system is installed in your home to assure you of proper airflow, comfort, and efficiency. In some extreme cases, I find actual splitter boxes or wyes made of this duct board to try and save money on new home construction. You can find these by looking for boxes made into triangle shapes with many ducts attached to them. These impede airflow, overwork the furnace blower, and provide inferior comfort to the entire home. They have to be replaced to make sure you are getting the full comfort and efficiency a new HVAC system can provide you.

The last and one of the most important aspects of your ducts is making sure they are sized properly to deliver the correct amount of airflow to each room in your home. Almost every homeowner I visit complains about the comfort in their bonus room or the room over their garage in a two story home. This discomfort is caused by lack of airflow to overcome the heat loss or heat gain in this special room, which is over unconditioned space and needs more air flow to make this room comfortable. I will never understand why builders ignore this room and provide a space that in many cases cannot be used in peak weather conditions. This problem is easily corrected when replacing your comfort system and should not be overlooked and if it is, the problem will still be there after the new system is installed.
One should never purchase a new HVAC system without having a competent contractor inspect the duct system to assure you that your new heating and cooling system will actually deliver the promise of comfort and efficiency that you should demand from this purchase.

Hail Damage To Your A/C Is Costly

Thursday, January 22nd, 2009

by DAN JAPE of Reliable Heating & Air originally published May 2008

In the past few months, there have been many severe hail storms in and around the Metro Atlanta area and many homeowners have had damage to their air conditioners that is costing them many hundreds of dollars in wasted energy dollars and their insurance companies are misleading them in a effort to reduce their losses.

Your air conditioner remove heat from your home by pulling air through a coil that is very much like the radiator in your car. This coil/radiator has fins made of thin sheets of aluminum bonded to copper tubing and when these fins were struck by hail in the recent storms, they were bent and damaged to the point of reducing and changing the airflow properties of your home’s cooling unit. These fins are critical in the operation and efficiency of your air conditioner and they can’t be repaired. Most of the insurance companies handling these storm damage claims refuse to help the homeowners with these damaged air conditioners due to the fact that it is very expensive to replace these damaged coils.

The outdoor unit and the indoor cooling coils are now a matched set and in 2007 the federal government mandated that all air conditioners be 13 seer or better. This means that insurance companies must spend $2800 to $4000 to bring you back to the point you were before the storm and the fact that the majority of the air conditioners that were damaged were 8 or 10 seer means the homeowner is getting something more efficient than they had before and this is apparently the sticking point with these companies. They don’t seem to mind replacing the roofs or gutters damaged in these storms because they can be repaired with like quality and kind. But the fact that they have to “upgrade” a damaged cooling system has been the source of many problems for homeowners.

Insurance companies have been telling homeowners that this damage is just cosmetic and they can simply comb out the damaged fins with a coil comb and have an air conditioning contractor straighten out the smashed fins. This will never work and will not bring back the cooling efficiency and air flow the unit had prior to the storm. This would be similar to your insurance telling you to beat out the damaged fender in you car with a hammer after a wreck and insisting you be happy with the results.

Except in this case, you will suffer by higher cooling bills and lost cooling capacity for many years to come if these units are not properly repaired and replaced. Do not let your insurance mislead you into not pressing a claim on you air conditioner just due to fact that it still “cools”. If your cooling unit was dented by hail and the fins of your coil were bent, you will never have the same cooling you had before and your insurance company knows this. There is no way to put an exact dollar amount on what it will cost you, but over years of operation, it could be many hundreds of wasted energy dollars. Insist your insurance company treat this damage the same way they are treating your roof, replace it or repair it will a new or like kind product.

As an update to the above blog, we found many of the a/c units that were just combed out like the insurance companies promoted failed completely due to a lack of refrigerant. The razor sharp edge of the aluminum fins cut through and weakened the copper tubing of the coil causing a complete loss of refrigerant. Insurance companies have taken advantage of many policy holders by insisting that this hail damage was not a functional problem, but only a cosmetic problem. But aren’t a number of issues an insurance company deals with simply cosmetic. There job is to restore a customer back to where they were before the damage occurred, not to argue and deny a legitimate claim. The really sad story behind all this is the insurance companies paid for thousands of twenty year old roofs without flinching and many of these claims were simply fraud. The people who had legitimate damage were in many cases turned away. Call me if I can help. 770 594-9969

Please TURN IT OFF before you DESTROY it!

Thursday, January 22nd, 2009

This time of year we are besieged with desperate phone calls from homeowners who have noticed there cooling systems not working properly or frozen up with ice. If this happens to you, turn the unit off immediately. Turn it off as soon as you can get to the thermostat! I know this is a tough request when it is hot outside, but if you continue to run an air conditioner that is not cooling up to par, you are going to do harm to your unit, waste your cooling energy dollars, and ultimately may permanently destroy your cooling system. I know this may seem hard to believe, but a large share of dead units we replace are killed by the owner refusing to turn it off when cooling is diminished. The one thing you can be assured of is, a broken air conditioner will never repair itself, no mater how long you continue to let it run. Never! Ever!

Many times customers will place a service call for no cooling and then continue to run their system thinking it might work a little until we get there to fix it. This is when most damage is done to the unit due to the lack of proper operating conditions. A unit that has frozen will do no cooling at all regardless of what common sense tells you and continued running in this condition will kill a compressor quickly. When you see ice anywhere on the refrigerant line set, you are seeing just the tip of an iceberg. The ice is covering the indoor coil preventing air from passing over the fins and it is five to six inches thick after continued operation. If you do not turn and let it thaw, you will burn out your compressor while wasting your money running a compressor that is not cooling your home. Also, if the unit is not thawed when the repairman arrives, he will not be able to find the problem and repair it properly.

A lot of customers will turn the unit off after it freezes and it will thaw and they turn it back on to find it cools again and they call our office and cancel their service call. This is a bad idea! What ever caused the icing will do it again after prolonged running and you will continue to damage your compressor . If you notice ice on your air conditioner, the first thing you should check is your air filter, as a dirty filter will cause icing and this is one of the most common problems we find. The other causes are a lack of Freon or refrigerant, a dirty indoor coil or a bad indoor fan motor. If any of these conditions are the cause of icing or lack of cooling, you must have a technician repair your unit.

One very simple thing you can do to check you air conditioner is go outside to your outdoor unit and carefully observe a few things. First, look for any ice anywhere on the unit, inside on the compressor or on the lines. Next see if there is hot air blowing out the top of your air conditioner. The hot air blowing out your unit is the heat being removed from your home and if the air is not hot, your unit is not cooling properly. The last thing you can do is located the large rubber covered line coming from your house and connecting to your cooling unit. It should always be cold and sweating water off the copper line inside the rubber insulation. If it is just cool to the touch and not sweating cold, you need service. This simply check and observation could save you thousands of dollars in energy costs and unit repair.
