How much does it cost to replace a Air Conditioner?


The Air Conditioner price will depend on the size of your home. Air Conditioners will vary in size and are specific to the square footage of the space being cooled. Prices also vary based on SEER (Seasonal Energy Efficiency Rating) which is the efficiency rating of the unit. AC efficiency ranges from 13 to 20 SEER. A lower efficiency 13 SEER Air Conditioner is less expensive, but wastes more electricity cooling your space. A higher efficiency 16 or 20 SEER Air Conditioner is more expensive but far more efficient, saving an estimated $21+ per month on electricity alone. If you really want high-efficient Air Conditioning, ask about the 2-Stage options. High-efficient A/C systems will also allow for utility rebates that make the upgrade easier on the check book. Financing is available as well. Ask about seasonal rebates, discounts, and same-as-cash financing.
