Frequently Asked Questions
About Commercial HVAC Construction
What does “commercial HVAC construction” include?
How do you size and select HVAC equipment for a commercial project?
We maintain a 24/7 emergency response service. During weekday business hours, we aim for a 2-hour response time, and outside business hours we target a 4-hour response time.
At THP Mechanical we factor these into our design-build process, using local climate and Northern California conditions (within ~150 miles of Sacramento) to optimize your system for efficiency and reliability.
What local/regulatory requirements should I be aware of in Northern California?
Commercial HVAC construction must comply with California and local jurisdiction codes—for example, energy-efficiency standards (such as those following ASHRAE 90.1 or California equivalents), ventilation and indoor-air-quality standards, refrigerant handling regulations (e.g., EPA Section 608), and seismic/structural requirements for rooftop units.
We ensure our projects meet all applicable codes and gain any required permits so your project stays on schedule and compliant.
How long does a commercial HVAC construction project typically take?
Project length depends on size and scope. A small tenant improvement might take a few weeks, while a full-building HVAC construction (new build, multi-story) could span several months. Key phases include design, permitting, equipment delivery, installation, controls setup and commissioning.
At THP Mechanical we provide a detailed project schedule and keep you updated, because delays in mechanical systems often impact the broader construction schedule.
What should a facility owner or property manager ask when selecting a contractor for HVAC construction?
Here are five important questions:
- “What commercial HVAC projects have you done in the Northern California (Sacramento region) market recently?”
- “Do you provide design-build services and coordinate with other trades (plumbing, electrical, fire-protection)?”
- “What warranty do you offer on workmanship and equipment installation?”
- “How will you minimize downtime or disruption during installation or retrofit?”
- “Can you provide a maintenance plan post-construction to keep the system operating optimally?”
At THP Mechanical we answer these questions thoroughly and support facility owners throughout the project lifecycle—from planning to commissioning and on-going maintenance.
