Our Air Conditioning Replacement Services

At Black Diamond, we believe that successful air conditioning replacement begins not with the installation of your new system, but with choosing the right unit. Our goal is to help you establish comfort while staying within your budget.

Sizing the unit for your property is the first step. Many homeowners are surprised to learn that their existing air conditioners are not sized properly for the home. Our contractors use ACCA Manual J standards to determine the cooling load requirements for your home. Manual J takes into account a number of structural elements to determine exactly what you will need to cool your home. Some of these include:

  • Duct leakage
  • Insulation provided through doors and windows
  • Insulation provided by walls and ceilings
  • Home or building size
  • Occupant generated loads

With that information in hand, our team will be able to choose an air conditioner that fits your needs and works with your budget. These sizing methods are accurate and up-to-date, so you can be confident that the system you end up with will efficiently cool your home. Once we select the unit, we will install it accurately, ensuring years of excellent service.

Crystal Club Maintenance Plans

Once your new air conditioner is in place, we will recommend you do what is necessary to maintain it well. This may include our Crystal Club Maintenance Plan. This plan helps maintain your unit well each year, including annual tune-ups and discounts on repairs.
