How to Find a Reliable HVAC Contractor in Lamorinda (Lafayette, Moraga, Orinda)
Your air conditioning quit on a hot summer afternoon in Lafayette, or your furnace won't start on a chilly Moraga morning. Maybe your Orinda hillside home needs a complete HVAC replacement. Finding a reliable, licensed contractor who understands Lamorinda's unique homes can feel overwhelming.
This guide shows you exactly how to find the right HVAC company for Lafayette, Moraga, and Orinda—and what questions to ask before signing anything.
Why Lamorinda Needs Local HVAC Expertise
Lamorinda isn't like other Bay Area communities. Your HVAC contractor needs to understand:
Hillside Construction Challenges
Many Lamorinda homes are built on slopes with:
- Split-level or multi-story designs requiring zoned heating/cooling
- Limited access for equipment delivery and installation
- Crawl spaces and attics that are difficult to navigate
- Longer refrigerant line runs between indoor and outdoor units
Larger Home Sizes
Lamorinda homes average 2,500-5,000+ square feet—significantly larger than typical Bay Area homes:
- Proper sizing is critical (oversized systems waste energy, undersized systems can't keep up)
- Multi-zone systems often make more sense than single-zone
- Ductwork design must account for multiple levels and wings
Established Neighborhoods with Older Systems
Many Lamorinda homes were built in the 1950s-1980s:
- Original HVAC equipment may be 20-40 years old
- R-22 refrigerant systems (phased out, expensive to repair)
- Undersized ductwork for today's efficiency standards
- Electrical panels that may need upgrades for modern heat pumps
Microclimate Variations
Temperature varies significantly across Lamorinda:
| Location | Summer High | Winter Low | HVAC Consideration |
|---|---|---|---|
| Lafayette canyons | 85-95°F | 38-45°F | Cooler, may need less AC |
| Lafayette ridgetops | 90-100°F | 35-42°F | Full sun exposure, AC critical |
| Moraga valley | 88-98°F | 36-44°F | Temperature swings |
| Orinda hills | 85-95°F | 35-42°F | Elevation affects sizing |
Step 1: Verify Licensing & Insurance
California Licensing Requirements
Every legitimate HVAC contractor must have a C-20 Warm Air Heating, Ventilating and Air-Conditioning Contractor License from the California Contractors State License Board (CSLB).
How to verify:
- Visit cslb.ca.gov
- Click "License Search"
- Enter company name or license number
- Confirm status is "Active" and "Current"
- Check for complaints or disciplinary actions
Galaxy's License: #1076868 (C-20 HVAC, C-10 Electrical, B General Building)
Required Insurance
Professional contractors must carry:
- General Liability Insurance ($1-2 million minimum)
- Workers' Compensation Insurance (protects you if technician is injured)
- Bonding (protects you if work isn't completed)
Ask for certificates of insurance before work begins.
Step 2: Check Local Reputation
Where to Look
Google Reviews (4.5+ stars with 100+ reviews = excellent)
- Look for reviews specifically mentioning Lafayette, Moraga, or Orinda
- Check recent reviews (last 6 months)
- See how company responds to any negative feedback
Yelp (similar standards)
- Filter by "Lamorinda" or specific city
- Look for detailed reviews with photos
Nextdoor
- Ask your Lamorinda neighbors for recommendations
- See which contractors are frequently mentioned positively
Better Business Bureau (BBB)
- Check rating (A+ or A preferred)
- Review complaint history
What to Look For
✅ "Knows Lamorinda homes" - Experience with local construction ✅ "Showed up on time" - Reliability matters ✅ "Explained options clearly" - Not just pushing the most expensive option ✅ "Fair pricing" - Reasonable for the quality provided ✅ "Professional crew" - Clean, respectful of your home
🚩 Red flags:
- "Tried to sell me a new system when I just needed a repair"
- "Price kept increasing after they started"
- "Didn't understand my multi-zone system"
- "Left a mess in my home"
Step 3: Lamorinda-Specific Questions to Ask
About Local Experience
Q: "How many homes have you serviced in Lafayette/Moraga/Orinda?"
- Want to hear: "Hundreds" or specific neighborhood names
- Red flag: "We mostly work in [distant city]"
Q: "Do you understand hillside home HVAC challenges?"
- Should mention: Access issues, zoning needs, line runs
- Red flag: Blank stare or "it's all the same"
Q: "Can you handle multi-zone systems?"
- Many Lamorinda homes need 2-4 zones for comfort
- Should be routine for an experienced contractor
About the Work
Q: "Will you provide a written estimate with itemized costs?"
- Must include: Equipment, labor, materials, permits
- Red flag: "I'll give you a number now, details later"
Q: "Do you pull permits for installations?"
- Answer should be "Yes, always"
- Contra Costa County requires permits for HVAC installations
Q: "What brands do you install and service?"
- Look for: Major brands like Mitsubishi, Carrier, Lennox, Trane
- Bonus: Factory-authorized dealer status
Q: "What warranties do you offer?"
- Should include: Manufacturer warranty + labor warranty
- Ask: "What's covered and for how long?"
About Pricing
Q: "Is this a fixed price or an estimate?"
- Fixed price = they've assessed the job properly
- Estimate = price may change (understand the range)
Q: "Are there any additional charges I should know about?"
- Permits, disposal, after-hours, etc.
- No surprises after work begins
Fair Pricing Guidelines (Lamorinda 2025)

- System type (heat pump vs. furnace/AC)
- Home size and complexity
- Equipment brand and efficiency
- Access challenges (hillside homes)
Heat Pumps vs. Traditional HVAC in Lamorinda
Many Lamorinda homeowners are switching from gas furnaces to heat pumps. Here's what to consider:
Why Heat Pumps Work Well in Lamorinda
✅ Mild climate - Temperatures rarely drop below 35°F ✅ Heating and cooling in one system ✅ Up to $8,000 in rebates available in 2025 ✅ Lower operating costs than gas in California ✅ No natural gas combustion in your home
Do You Need Hyper Heat in Lamorinda?
For most Lafayette, Moraga, and Orinda homes: No.
Hyper Heat (cold-climate) heat pumps are designed for temperatures well below 0°F. Lamorinda rarely sees temperatures below 35°F. A standard heat pump handles our climate beautifully at $2,000-$3,000 less cost.
Exception: If your home is at high elevation with frequent frost, consider a cold-climate model for peace of mind.
Red Flags: When to Walk Away
🚩 No C-20 license or "license not required for this job" 🚩 Refuses to provide written estimate 🚩 Pressure tactics: "This price is only good today" 🚩 Can't explain the problem in terms you understand 🚩 Pushes replacement without diagnosing the issue 🚩 No insurance or won't provide certificates 🚩 Cash-only payment required 🚩 No Lamorinda references 🚩 Unmarked vehicle with no company branding 🚩 Price far below other quotes (usually means cutting corners)

Frequently Asked Questions
Q: How do I know if my Lamorinda home needs a multi-zone HVAC system?
A: Multi-zone systems make sense if your home has multiple levels, wings that heat/cool differently, rooms that are consistently too hot or cold, or if family members prefer different temperatures. Most Lamorinda homes over 2,500 sq ft benefit from zoning.
Q: Should I repair or replace my old HVAC system?
A: Consider replacement if your system is 15+ years old, requires frequent repairs, uses R-22 refrigerant (phased out), or your energy bills have increased significantly. See our 7 warning signs it's time to replace guide.
Q: What rebates are available for Lamorinda homeowners in 2025?
A: Available incentives include: HEEHRA rebates up to $8,000 for income-qualified households and federal tax credits up to $2,000 (through Dec 2025). Note: TECH Clean California is fully reserved and BayREN ended April 2024. Heat pump installations qualify for the highest rebates.
Q: How long does HVAC installation take in a Lamorinda home?
A: Most installations take 1-2 days for straightforward replacements. Larger homes, multi-zone systems, or installations requiring ductwork modifications may take 2-4 days.
Q: Do I need a permit for HVAC work in Lafayette, Moraga, or Orinda?
A: Yes. Contra Costa County requires permits for HVAC installations and major modifications. A licensed contractor handles permit applications and inspections for you.
