Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

These prices should only be used as a guide only, and the actual quote you receive form a local contractor may be lower or higher. You should receive a written proposal from a licensed HVAC contractor before making any decisions about buying or remodeling a house with an older HVAC system. Here’s just a few of the many things that will change the pricing:

  1. BulletInstallation of air handler in an attic, or any location that requires a catch pan under unit and more difficult access.

  2. BulletHigher SEER rating than 14.

  3. BulletRelocation of condensing unit or air handler.

  4. BulletChange in pricing of raw materials, such as copper, for the manufacturer.

  5. BulletHow competitive the local market is.

  6. BulletAny necessary repair to existing ducts or walls

  7. BulletReplacement of registers.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
