Our mission is to provide the best renovation service at an reasonable price without sacrificing quality. You will be satisfy with our work knowing we take the necessary steps to meet your needs and get the job done right. Tougher energy standards for window air conditioners that went into effect two years ago make newer models cheaper to run. Look for a unit with an Energy Star label and an Energy Efficiency Ratio (EER) of 10 or above. The higher the EER, the lower your operating costs.
