An air conditioner for your home is an important investment, but with the range of options available, which type and model should you choose? If you live in an older home without existing duct work, don’t think you must settle for an in-window unit that may be inefficient, noisy, and insecure. Instead, consider a mini split ductless air conditioner. These offer flexible mounting options, high efficiency, and quiet operation. Their drawback is that they typically only cool one or two rooms, where you’ve chosen to mount the indoor units. If you already have furnace ducts in place you can add an integrated, central air conditioner. Again, you have a number of options. Conventional single-stage units cost less initially, but two-stage units are more energy efficient over time. Some units are specially designed for quiet operation, which is important if the outside unit is situated near your windows or your neighbour’s home. Supplement your air conditioner with a heat recovery ventilator (HRV). This can reduce your cooling and heating costs while controlling humidity levels in your home. Whatever type of air conditioner and related equipment you choose, it’s important that it be sized correctly for your home. An undersized system won’t provide the cooling you require, while an oversized system will tend to cycle more frequently, increasing wear and reducing efficiency. How do you determine the correct size? It’s easy to calculate the square footage of your home. However, other factors come into play as well. How well the house is insulated, its exposure to the sun and wind, the condition of door and window seals, and more can determine which size is right for you. Purchasing an air conditioner for your home is an investment, so be sure to get professional help in making your decision.
