HVAC Retrofits

HVAC Services in Saint LouisRegardless of how well your HVAC system is maintained, age and building expansion will eventually cause you to replace it. This critical decision needs consultation from professionals such as American Services HVAC repair in St. Charles, and a well thought out plan.

HVAC system replacements are a costly process that can disrupt building operations over an extended period of time. A well thought out plan including consultation with a certified HVAC designer helps ensure that the retrofit produces maximum benefit. This will enhance operations of the facility, and immediately generate energy cost savings. A good plan will also make sure that the retrofit process will not have to be repeated in the future secondary to poor planning and impulsive decision making.

8 steps to keep in mind for an  HVAC retrofit:

  1. The quickest and easiest way to replace older HVAC systems is to put in a new system that matches the old one. Match components by type, compatibility, voltage/amp output, and then replace with new components of exactly the same profile. This process will work if there are no changes in your building.
    2. New technologies result in tremendous progress in the last 15 years as far as HVAC technology. New DDC control systems provide a better climate while reducing energy costs. High efficiency chillers can reduce the cost of air conditioning. Variable frequency drives improve operating efficiency. These are all proven new technologies and are used widely today in modern installations.
    3. Modern buildings today are under a constant state of change. Interiors are upgraded; tenants are moving in and out, infrastructure changes increase. The one thing that doesn’t change is your HVAC system trying to support all these changes. This is why flexibility must be built into your HVAC system retrofit.
    4. Part-load performance-chillers are the single largest users of electricity improving the efficiency of chillers is what chiller manufactures strive to do. When selecting replacement chillers, pay attention to full load efficiency ratings
    5. Maintain records of maintenance performed on your building, maintenance costs, increasing maintenance requirements.  Implement a preventative maintenance checks and services checklist for your building’s maintenance staff.
    6. Seeing the big picture- most generally tunnel vision develops when planning for HVAC retrofits focusing on only specific components or portions of the entire HVAC system. Experience shows, before making retrofit decisions facility executives should step back and determine if other projects planned for the building will affect the HVAC system operation.
    7. The major goal of any HVAC retrofit program is to improve the level of service.  Facility executives should consult the occupants and be willing to receive input. Facility executives can then develop a clear understanding of what the HVAC system will be expected to do.
    8. Program approval-HVAC retrofits are costly programs.  More often than not facility executives simply submit funding requests with little or no supporting information, the outcome, “Funds Denied”. Put a band aid on components and just patch systems together, to keep things going. An HVAC retrofit is a major undertaking for the Facilities Department, the occupants, and organizations management. A certified HVAC systems designer, HVAC component manufacturer should all be brought in during the planning phase.
