Energy Star Recommendations

Maintain Your Equipment
Dirt and neglect are the top causes of heating and cooling system inefficiency and failure. To ensure efficient system operation, it's important to perform routine maintenance.

Change your air filter regularly.
A clean filter will prevent dust and dirt from building up in the system, which can lead to expensive maintenance and/or early system failure. Check your filter every month, especially during winter and summer months, when use tends to be heavier. Change your filter if it's dirty- or at least every three months.

Tune up your HVAC equimpent.
Proper maintenance by a qualified technician is one of the most important steps you can take to prevent future problems. Contractors get busy during summer and winter months, so it is best to check the cooling system in spring and the heating system in the fall. Plan the check-ups around the beginning and end of daylight-savings time each spring and fall.

Your contractor should complete the following each spring and fall:
Check thermostat settings to ensure the heating and cooling systems turns on and off at the programmed temperatures.

Tighten all electtrical connections and measure voltage and current on motors. Faulty electrical connenctions can cause your system to operate unsafely and reduce the life of major components.

Lubricate moving parts.
Parts that lack lubrication cause friction in motors and increase the amount of electricity you use. Lack of lubrication can also cause equipment to wear out more quickly, requiring more frequent repairs or replacements.

Check and inspect the condensation drain in your central air conditioner, furnace, and/or heat pump (when in cooling mode).
If plugged, the drain can cause water damage in the house, affect indoor humidity levels, and breed bacteria and mold.

 Please compare also with the image I sent last rolex replica to confirm that this is actually the edge of the bubble it is a little hard to see under the red. The date should be centered underneath this bubble, like rolex replica sale is in the link below, and like it is for every other Rolex I have seen. I know it is a bit hard to spot the edges of the bubble in the rolex replica sale but in real life this is very obvious. I think part of the problem is also that the date fake rolex is too small compared to the bubble, but nevertheless it should certainly be centered. A shot anyway and still nothing rado replica sale so now would like to return this as was a Christmas present and would been nice if rolex replica sale had worked. Could you confirm as requested in last email about costs and forward me the address to send the watch back please.
