Spring Cleanup List Begins with HVAC

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.

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.

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.
