Next, we measure your current HVAC and plumbing systems and surroundings for any performance issues as we want to know where the underlying problem may be. Depending on the issue(s), we will suggest helpful maintenance and preventative tips based on the problems you are currently dealing with.

Measuring Your Home – the THA Way

At THA, we don’t believe in quotes due to the fact that every San Diego home and building is built differently. Due to the individuality, we believe that it’s far better to take things personal by thoroughly measuring factors such as:

  • individual rooms
  • window sizes
  • insulation levels
  • types of siding
  • …plus many more, including a Manual J Load calculation for your air conditioning units.
