HVAC
Summary Items
- CHS-1 Common HVAC Systems - Heating, Cooling and Ventilation:
HEATING AND COOLING SYSTEMS OVERVIEW
Overall, the occupied spaces of the building are being properly controlled. There appear to be too many units on the rooftop, and in the attic spaces there appears to be an abandoned air handler. It appears that some upgrades have been made over time (there were two newer rooftop compressors) and it appears that the systems that were replaced have just been left in place. This building has had (at least) two major tenants over its lifetime, the newer units may be part of tenant improvements when the current occupant took possession.
Major Concerns
- CHS-2 Common HVAC Systems - Heating, Cooling and Ventilation:
HVAC SYSTEM UPDATING IS NEEDED
The HVAC systems for this building need updating. The following observations were noted during the inspection:
- The main RTU appears to be original to the building (data plate is illegible, and the compressor fin damage reflects substantial age), this would put it close to projected end of service life.
- Many of the smaller units are definitely original, and should be considered for replacement as well.
Recommendation
If you cannot get the maintenance and expected lifespan records from PSR Mechanical (206-367-2500), then hire an independent qualified heating contractor to further evaluate and provide a plan and budget for updating the HVAC systems here as needed.
Repair Items2
- CHS-3 Common HVAC Systems - Heating, Cooling and Ventilation:
HVAC SYSTEM REPAIRS ARE NEEDED
The following observations were noted during the inspection:
- The compression line set for the Mitsubishi split system is missing all of its insulation above the roof.
- This Mitsubishi split system is for the IT computer room only. It appears to have problems, since they have a secondary portable AC unit set up in the server room currently.
Recommendation
Have the Mitsubishi HVAC system further evaluated and repaired as recommended by a licensed heating contractor.
Recommended Maintenance Items
- CHS-4 Common HVAC Systems - Heating, Cooling and Ventilation:
SERVICE THE HVAC SYSTEM
No recent service records were noted on the HVAC system.
- Many of the compressors on the rooftop appear to be original to the buildings construction, the data plates are so worn that you cannot get an idea of model or serial number.
- It does appear that the systems have had prior maintenance and tracking through a service agreement, there should be records of which units are still functional
Recommendation
Have the HVAC systems serviced by a qualified contractor.
