Central Air Conditioner Not Immediately Turning On.?

When you say FAN do you refer to the fan outside on the condenser unit? If so then you may have a compressor going off on internal high heat overload safety It takes about 20 Minutes for it to cool and restart. If you refer to the Indoor fan . it could be that the fan motor is beginning to fail Do you have a didgital type thermostat? That can be a culprit also(defective) Or thermostat can have a loose wire connection

1. My central air conditioner seems to cycle on and off a lot.?

that means that the controller for the air conditioner is set to too small of a range. for example it turns on at 76 degrees and turns off at 75 degrees. on a properly set air conditioner it should be set to turn on at 78 and turn off at 74, or some range like that

2. How can I know the BTU/H for a central air conditioner in my home?

My home is about the same configuration, 3500 sqft, in north TX and have total 9 ton (54). 1 ton = 12,000 BTU/hour.

3. I am trying to determine what size central air conditioner I need for my home?

answer is very simple, multiply the area with the height of the rooms and divide that by 1000. in your case it will be 3265 * 10 ( assuming 10 feet height of the room ) comes out to 32650 divide this by 1000 it comes out to 32 ton for the whole house not 3 to 3,5 ton. 3 ton ac is suitable for 300 square feet room only. Install AC room wise following the above calculation and you will benefit in this. Read more on calculations in the following link

4. Why does my chimney backdraft when I run the central air conditioner and the clothes dryer?

Some of the posters have hit on it. You need more make-up air in the house. Vent fans, dryers, range vents and furnace/AC all create a negative pressure in your house when in use. To make up for that, air is drawn in wherever possible. The answer is to add a make-up air vent which leads into the return air trunk of your heating and cooling ductwork. What it is: depending on the size of the home, probably a 6" duct that has a vent to the outside of the home (or 2 6" ducts in a larger home). There is a baffle inside the duct that only opens when a negative air pressure situation arises. It can be done as a DIY project if you have any "tin knocking" experience. Otherwise any local heating and cooling company can do it for you in about an hour or two. You will find this a better solution than opening doors, windows or flues.

5. Can grass and other debris in the fan outside affect the central air conditioner inside the house?

Yes, the debris definitely can affect your air conditioner. According to the blog from American Home Water and Air: "If you suspect the debris has made its way inside the unit, you will need to have a professional open it up safely. First, however, brush away any debris yourself with a small-handle broom and give the coils a good cleaning with water and coil foam cleaner." Apparently, it is a very common problem with AC units.

6. What makes our central air conditioner keep freezing up and not work ?!?

several people have the right idea here.. low refrigerant level can cause the unit to eventually freeze up in humid conditions. low refrigerant level also means there is a Leak in the system. the refrigerant in an air conditioner is not consumed, it simply goes around and around in circles. make sure your air filter is clean. your friends should also have checked to make sure that there is not a large buildup of dirt on the evaporator coil, as this can cause system freezing. if the system has a liquid line filter / dryer on it, this device can become clogged up and could restrict the flow of refrigerant. you A/C repairmen need to check the superheat and sub-cooling on the system, and measure the pressures and compare with a Pressure-temperature chart. if they replaced a blower motor, they need to be sure the blower wheel was not installed backwards which would cause low airflow over the evaporator and let the system freeze up. you should not have to let your A/C unit "rest".

How to Know Which Central Air Conditioner Is the Quietest Cool Today
For example, on Carrier's website you can see the quietest ACs by comparing their dB (sound) levels. The Infinity 19VS is quieter than the Infinity 21, as you can see from its lower dB level Note: It says "as low as." Which means it's the lowest decibel level achieved from the quietest size within each model group during low fan-speed operation. Currently, the 50-60 dB range is as quiet as an air conditioner can get. As of 2015, some of the quietest ACs include: OK, so what do those numbers mean, though? How loud is 65 or 56 decibels? How will you know if the AC is quiet enough for you? For a frame of reference, Purdue University's Chemistry Department gives you examples of noise sources for each decibel level: • 50 dB (1/4th as loud as 70 dB) - Quiet conversation at home • 60 dB (1/2 as loud as 70 dB, fairly quiet) - Conversation at a restaurant • 80 dB (twice as loud as 70 dB) - Running a garbage disposal So, if you are looking for a quiet AC, make sure it's within 50 to 60 dB. If you can not find an AC's sound level, look for certain features that imply quietness, including: • Variable speed fan — The indoor unit's fan can operate at different speeds depending on your comfort needs. This improves comfort, lowers energy bills and, of course, lets the AC run at quieter speeds. • Compressor insulation — A separate compartment or enclosure that covers the compressor to reduce the outdoor unit's noise. • Insulated base pan — An addition of a pan underneath the air conditioner designed to reduce noise and resist corrosion. Remember that any sound rating you see implies two things: • The size of the AC is the quietest size (probably a smaller size). Size is measured in "tons." • The AC's indoor fan is running at the lowest setting. In other words, the advertised sound (dB) is the AC running under perfect conditions. So if you have a larger home (implying a larger AC) and live in a hotter area like Florida (implying that the fan will run at a higher setting) the AC you buy will probably be louder than advertised. How do you know which AC size you need? You will need to get a professional AC installer to perform a Manual J Heat Load Calculation on your home. Most reputable HVAC companies will do this for you free of charge as part of an air conditioner installation estimate. Nice, right? You are free to choose the first offer you get or leave it to find someone else with no charge to you. Related article: How Do I Know What Size Central Air Conditioner I Need for My Home?

They are much more absorbent. You dont need to change them as often, so that balances out the cost. I do not notice anything great about the U, other than the pretty packaging. I admit I was sucked in by that too, but next time I would go back to the infinity.define and explain ohm law?When a voltage source (Battery) is connected to a circuit, it will require a resistor to control the amount of current flowing in the circuit. Equation: (V=IR) V=Voltage, I=Current, R=Resistance. If the restistance is 0 ohms the current will go to infinity, causing the circuit to short. Adding a resistor to a circuit also allows a certain amount of current to enter a componentI need the perfect summer play list for a bbq anything alternative, rap hip hop n e thing please?As far as hip hop goes...
