Celeste·Climate
Heating, cooling, indoor comfort.
Your home's climate system is invisible when it works and impossible to ignore when it doesn't. Celeste approaches HVAC as a performance system — properly sized, correctly installed, and integrated with the rest of your home's envelope.
Scope of Work
What we do.
System Replacement
Complete replacement of existing HVAC systems — including air handler, condenser, and ductwork where needed.
Mini-Split Installation
Ductless mini-split systems for additions, conversions, and homes without existing ductwork.
Duct Sealing & Replacement
Leaky ductwork is one of the most common sources of energy waste in Southern California homes. We test, seal, and replace.
Condition Assessment
Standalone evaluation of your existing HVAC system — performance, efficiency, and remaining service life.
Product Philosophy
We specify what we believe in.
HVAC in Southern California is primarily a cooling challenge — but the right system also handles the occasional cold snap efficiently. Celeste specifies systems that are properly sized for your home's actual load — not oversized for the sake of a sales pitch — and installed with the attention to detail that determines long-term performance.
Manual J Load Calculation
Every Celeste HVAC specification begins with a proper load calculation — not a rule-of-thumb estimate.
SEER2 Rating
We specify systems that meet or exceed California's minimum efficiency requirements — and explain the trade-offs.
Refrigerant Compliance
All Celeste HVAC installations use current-generation refrigerants compliant with California regulations.
Duct Leakage Testing
We test duct leakage before and after installation — and document the results.
Process
How a Celeste climate project works.
01
Assessment
We evaluate your existing system — performance, efficiency, condition, and remaining service life.
02
Load Calculation
Manual J load calculation for your home — the foundation of a properly sized system.
03
System Specification
We specify the appropriate system for your home's load, layout, and performance goals.
04
Installation
Careful installation with attention to refrigerant charge, airflow, and duct connections.
05
Commissioning
System startup, performance verification, and documentation — including duct leakage test results.
Southern California considerations.
Cooling Dominance
Southern California homes spend far more energy on cooling than heating. System selection should reflect this reality.
Duct Losses
Ducts in unconditioned attic spaces — common in Southern California — can lose 20-30% of conditioned air. Sealing matters.
Title 24 Compliance
California's energy code has specific requirements for HVAC replacement. Celeste ensures every installation is compliant.
Air Quality
Southern California's air quality challenges make filtration and ventilation important considerations in any HVAC specification.
