Here are some of the most common AC brands and how much their compressors cost before installation: Compressor Brandīecause of differences in manufacturing, you’ll typically need to replace your AC’s compressor with a new one of the same brand. However, they’re also the most complex and expensive to replace. Finally, variable-speed compressors can operate at any capacity from 0% to 100%, allowing for the most precise temperature control and greatest efficiency. When the air temperature is close to the desired temperature, the low setting will run the unit at 60% to 70% capacity, making the unit quieter and more efficient. Two-stage compressors, on the other hand, have a high and low setting. They’re the least expensive models, but they’re also the least efficient. Single-stage compressors run on an all-or-nothing basis, running at full capacity until the air temperature matches the temperature on the thermostat. When you replace the compressor, you’ll need to use a model of the same type. Residential air conditioners have either single-stage, two-stage, or variable-speed compressors. You’ll also need to pay for any necessary parts. For compressors that can be repaired, most technicians charge between $100 and $150 per hour for labor. Most of the time, if they’re broken, they must be completely replaced. Unfortunately, bad AC compressors can rarely be repaired on-site. Repairing or replacing your AC compressor may include these elements: Aside from the size of the unit, the variation in AC compressor replacement costs can be explained by a few other factors.

The two diagonals of the rectangle ABCR are AC and RB in which RB is being as radius of the circle. Subtract 8 from the perimeter found in step 1. Given : The length plus width of rectangle ABCR is 8. Perimeter of one quarter of the circle STR is Then, add the the length of the diagonal (AC). Subtract the length (AR) and width (RC) of the rectangle ABCR from the above perimeter. If the length plus the width of rectangle ABCR is 8, Then the perimeter of the shaded region isįind the perimeter of one quarter of the circle STR. In the figure above, arc SBT is one quarter of a circle with center R and radius 6. So, the starting card count in terms of n is Given : Final card count after these two turns is n. Number of cards after increasing 36% of cards on the second turn : Number of cards after losing 18% of cards on the first turn : If his final card count after these two turns is n, which of the following represents his starting card count in terms of n? On the second turn, he increases his card count by 36 percent. On his first turn, he loses 18 percent of his cards. William is playing a board game in which he has to collect as many cards as possible. That is, both the equations must have the same slope and same y-intercept. If a system of linear equations has infinitely many solutions, the two equations must be equivalent. Write the given two linear equations in slope-intercept form : If 2 √p + 3 √q = 7 √q, where p > 0 and q > 0, what is p in terms of q? Therefore, equation of the required line is Since (1) contains the point (1/2, 3), substitute x = 1/2 and y = 3. (since the lines are parallel, the slopes must be equal) Since the line is a falling line, the slope has to be negative.Įquation of the line which is parallel to the above line is Since the equation is identity, each side is the same. If the linear equation above is an identity, what is the value of n? If x = 1 - a/b, which of the following is equivalent to 1/x? If f(x) = x/2 - 1, what is f(-2x + 1) equal to?
