1. Do high-efficiency filters harm my air-conditioning system?
This depends on how often you change your filter. Filters need to be changed out at least every 2 months, regardless if it is a high-efficiency filter. In addition, some high-efficiency filters restrict the air flow because the filter is thicker, which forces your blower motor to work harder and harms your AC system.
2. I have never changed my filters. Every time I check them, they look like the day I bought them.
Regardless of how your filter looks like, it needs to be replaced every 2 months. There are small particles that cannot be seen with the eye that the filter catches, so it needs to be changed out every 2 months.
3. Can I use the vacuum cleaner to vacuum the vent?
4. How important it is to DO regular maintenance on heat pump unit?
Regular maintenance your AC unit has some benefits:
If the AC already has some problems but not bad enough to stop the heat pump working, the technician can correct the problem before the units completely stops working.
During maintenance, the technician can determine potential problems.
Fix issues found from maintenance to prevent the units from getting into a worse condition.
5. Why is my air conditioner sucking in the filter? What kind of filter should I use for my central ac unit?
It may be caused by a couple reasons:
The air filter is not the correct size.
The filter track isn’t holding the filter properly in place.
The air filter is getting wet then is getting sucked in by the blower motor. If the air filter is getting wet, you need make sure the drain pan is in good condition and the drain pipe is clean.
6. Can a maintenance mistake cause Refrigerant to leak from unit?
Yes, it is possible. For example, when a technician is reading your AC unit pressure, he needs to remove the gauge. If the thread core is not tightened enough or if the cap is not placed back on the service valve, refrigerant will leak.
7. Some rooms in our house are too hot (or cold). Can this be fixed?
Two ways to solve this problem: 1. Adjust the air damper to increase more air to the room you need warmer. 2. Close the vent in the room that is too hot, and completely open the vent in the room that is too cold.
8. My kid dropped a bowl of cereal down the vent. Is there any way to get it out?
Remove the register cover and use a vacuum cleaner hose to clean up.
9. Does an AC unit use more electricity if it is not functioning properly? For example is the capacitor not functioning properly?
Yes, if your AC is not functioning properly it will use more electricity. The AC will not work if the capacitor goes out. From May to June weather, since the weather is getting hotter, the AC will need to work harder to keep the house cool, which will increase your electricity bill. To reduce your electricity bill, you can replace your windows and doors to the energy efficient type. It is also recommended to keep the temperature setting at 76 degrees.
10. How do I balance the air supplied to each room of my house?
Close the vent half way or completely in the rooms that do not need the air.
11. How can I estimate how much I'm spending on air conditioning?
The related load amperage (RLA) is the actual number of amps that your AC draws when running. It can be found on your air conditioner’s data tag (see pic) which is located on your air conditioner. For accuracy, this number should be used, or you can use the average number to calculate. First, you’ll need know the amount of tons on your AC unit: 2-Ton Air Conditioner – 15 amps 3-Ton Air Conditioner – 18 amps 4-Ton Air Conditioner – 21 amps 5-Ton Air Conditioner – 30 amps For example: You have a 3 ton AC. We use the average number 18 amp x 240 volt = 4,320 watts. 4,320 watts /1,000 = 4.32 kilowatts per hour. Check your electricity bill to determine the amount the power company charges per kilowatt. Let’s say 15 cents. 4.32 kilowatt/hour x 15 cents = 64.80 cents per hour. 64.80 cents x 24 hours = 1,555.2 cents = $15.552 per day. $15.552 x 30 days = $466.56 per month. This figure is assuming that your AC is running 24 hours a day, but the reality is your AC is not constantly working. It only runs when the temperature on the thermostat goes above the temperature you set. For instance, if you were to set your thermostat to 100 degrees then your cost for air conditioning would be $0, because your air conditioner would never run, assuming that the house’s temperature is never above 100 degrees. The following coefficients are the averages that can be used. There is no exact way to calculate the proper multiplier: 110 degrees – 0.8 100 degrees – 0.4 90 degrees – 0.3 80 degrees – 0.25 Let’s say the average outdoor temperature is 100 degrees. The multiplier is 0.4 x $466.56 = $186.24, which is the approximately the total spent on your AC every month.
12. Maintenance tip.
Maintenance tips: 1. Keep pet hairs off the floor, since it can be sucked into the duct and recycled into the air. 2. Keep the floor clean from outdoor dirt (from outdoor shoes), since dirt particles can be sucked into the duct and recycled into the air. 3. If you find that your registers are dirty by opening it up, have a duct cleaning company clean the ducts, and ensure that they use a large vacuum that is connected to a truck, versus using a portable vacuum for power. 4. Replace the air filter at least every two months.
13. How often should I have my air ducts cleaned and inspected for repairs?
As long as you replace the air filter every two months, the air ducts do not need to be cleaned. If your house is old and you don’t know if the duct is clean, you can open one register to check to see if the duct inside is dirty. Ensure that they use a large vacuum that is connected to a truck, versus using a portable vacuum for power.
14. My electric and gas bills are high. Will a new furnace and air conditioner lower my bills?
