For HVAC Contractors

Your contract requires it. CLīMIT proves it.

HVAC contracts require you to install, commission, and hand off systems within specified environmental conditions. Without continuous monitoring and documented proof, you're exposed, even when you did everything right.

The Three Critical Conditions

Your contract specifies these.
Can you prove you met them?

Most HVAC contractors rely on memory and verbal assurances. The ones who win disputes have timestamped environmental logs. CLīMIT gives you that data automatically.

Temperature Control

HVAC contracts typically require you to maintain specific temperature ranges during commissioning, startup, and seasonal handoff. If ambient temperatures fall outside these windows, from cold snaps to heat waves, equipment performance testing becomes invalid and commissioning must be redone.

Common Risk Factors

Commissioning test results invalidated by out-of-range ambient temperatures
Refrigerant charging errors when ambient temps fall outside equipment rating windows
Control system calibration drift caused by extreme temperatures during startup
Ductwork sealing failures when adhesives are applied in cold or hot conditions
Variable air volume (VAV) box calibration errors from non-standard conditions

Humidity & Moisture Control

Humidity directly affects HVAC equipment performance. High moisture levels during installation cause corrosion of control boards, coil degradation, and mold growth in ductwork, all of which become your liability if discovered after handoff. Most contracts require you to maintain RH within a defined range throughout the project.

Common Risk Factors

Condensation forming on coils and refrigerant lines during installation
Mold colonization inside ductwork before the system is commissioned
Control board corrosion from high humidity during extended construction periods
Insulation absorbing moisture and losing R-value before system startup
Owner disputes over air quality at project handoff due to undocumented conditions

Ventilation & Air Quality Compliance

Your contract often requires you to demonstrate that the HVAC system achieves specified indoor air quality and ventilation rates under real conditions. Without documented environmental data throughout the construction phase, proving compliance to the owner, architect, or commissioning agent is nearly impossible.

Common Risk Factors

ASHRAE 62.1 ventilation compliance cannot be demonstrated without condition records
TAB (testing, adjusting, and balancing) reports disputed without ambient data
Indoor air quality deficiencies blamed on HVAC when root cause is construction conditions
Owner refusal to accept system based on undocumented pre-occupancy conditions
Punch list disputes over performance that was affected by ambient environment
The Cost of No Documentation

What's at stake without condition records.

Recommissioning Costs

When test conditions fall outside contract-specified ranges, commissioning agents require full retesting, costing tens of thousands and delaying project closeout.

Contract Disputes

Without documented environmental conditions, you have no defense when owners dispute system performance. Data is your proof or your vulnerability.

Project Delays

Failed commissioning, warranty disputes, and punch list extensions caused by undocumented conditions push closeout by weeks and withhold retainage.

Warranty Exposure

Manufacturers void equipment warranties when installation or startup occurs outside specified environmental conditions. You inherit that liability.
