Commercial - Tenant Improvements

Mechanical Air Service specializes in tenant improvement work. Depending on the project scope we may handle the HVAC and Electrical requirements on a project. We are one of the very few HVAC contractors that also have an electrical license.

Mechanical Air Service is well known for completing a project on time and on budget. Since our inception in 1976 we have never missed a deadline. In addition, if a project scope changes we will provide cost effective options for consideration.

Some of the types of tenant improvement work we do are:

  • Typical office interiors.
  • Conference room additions.
  • Server Rooms
  • Clean Rooms
  • Special needs areas

The following are some preliminary cost estimates for some typical package unit sizes. The pricing matrix is for a new installation, single story building with good access. The preliminary cost estimates include ductwork installed prior to the installation of a t-bar ceiling and mostly open area, a new programmable thermostat and full commissioning services. Typically when installing a new system there are additional related costs for items such as:

  • Structural engineering and framing, if needed.
  • Electrical service, gas service, condensate drain line
  • Economizer (If the unit is over 5 tons)
  • Energy calculations
  • Roof patching
  • Third party duct testing if required

Please note:  When replacing a unit with a new system of equal size even if it weighs less than the old unit most cities will require a structural engineering review because of the revised seismic codes.

Rule of thumb for AC unit sizing: A common rule of thumb method to determine the number of tons of cooling for general office and R&D space is to divide the gross area by 350-400 (one ton cools 350-400 square feet) -the result is the number of tons required. Actual base heat loads, building envelope load as well as other factors can and will influence the final system sizing.
