An HVAC system is a big expense, so it’s logical that homeowners would want to cut costs wherever they can. However, an improper installation can ultimately result in long-term issues and costs they may not foresee. Air conditioning installation is a complicated lengthy task that should be handled by experienced, knowledgeable technicians. If not, your AC could become a huge energy expense.

An HVAC system that is not installed properly can have a shorter lifespan and be more prone to break. When your HVAC system is installed by an experienced professional it will be installed with the space and manufacturer specifications in mind and adjusted accordingly.

Common HVAC Installation Errors

  • Not Choosing the Right Size Unit – Today’s HVAC units are smaller and more efficient.
    A larger HVAC unit may not be better. A HVAC professional should help you choose the right size system for your space.
  • Poor Duct System Design – The efficiency of your AC is only part of your overall system’s efficiency. Ask your HVAC installer if they are replacing the ductwork or leaving what was there. In most cases, this should be replaced when installing a new unit to avoid any leaks.
  • Improper Drainage – Today’s more energy efficient furnances and ACs can produce more waste water. A mistake with your drain can result in many problems including mold and mildew.
  • Not Having the Right Amount of Refrigerant – A proper HVAC installer will make sure your refrigerant is the right amount for your inside coil and lines. They shouldn’t rely on the amount that it comes with.

The Impact of Improper Installation
A study by the National Institute of Standards and Technology indicated that improper installation can increase energy consumption by 30%. The study also determined that leaky ducts were the primary cause of energy loss. The other most commonly found issues were oversized systems, restricted air flow, and improper refrigerant charging.

Auditing Your Installation
Are you experiencing extremely high energy bills? You may want to schedule an audit of your HVAC installation to make sure these errors didn’t increase your bill. Get a second opinion and determine if there are corrections that can be made to your system to get your energy use back on track.
