Consider Evergreen Air HVAC if...
- ✓ You need emergency HVAC service today and Evergreen Air HVAC has immediate availability in the Palo Alto area, as they consistently deliver same-day response.
- ✓ Your project is straightforward like a capacitor replacement, refrigerant recharge, or standard system swap where additional diagnostic experience provides less value.
- ✓ You've received quotes from multiple contractors and Evergreen Air HVAC's competitive pricing significantly undercuts other bids for comparable equipment and service.
- ✓ You prefer working with a Palo Alto-based contractor for quicker response times to your specific neighborhood.
Consider Tempro if...
- ✓ Your HVAC system has ongoing issues that previous contractors couldn't resolve, as Tempro customers specifically mention correcting other contractors' mistakes.
- ✓ You're dealing with a complex multi-component installation, system overhaul, or ductwork problems where diagnostic experience becomes critical.
- ✓ Your home has older HVAC infrastructure that may hide complications like asbestos-wrapped ducts, outdated electrical panels, or non-standard configurations requiring seasoned problem-solving.
- ✓ You're in San Jose and prefer a local contractor with two additional years navigating permit requirements and building code updates in your jurisdiction.
Questions to Ask Before Hiring
- → Ask both contractors how many projects similar to yours they've completed in the past year, particularly if your system involves ductwork complications or multi-zone configurations.
- → Ask Evergreen Air HVAC how they handle unexpected complications during installations, and whether the owner personally supervises complex projects given their shorter track record.
- → Ask Tempro for specific examples of correcting previous contractor mistakes relevant to your situation if you're dealing with ongoing system problems.
- → Confirm warranty coverage details for both labor and equipment, and ask who handles warranty service calls if problems emerge after installation.
The Bottom Line
Tempro's five years of licensed experience provides a meaningful advantage for most homeowners, particularly those dealing with complex installations, ongoing system problems, or older homes where hidden complications are likely. The company's track record of diagnosing and correcting previous contractor mistakes suggests stronger problem-solving capabilities developed through additional field experience. Evergreen Air HVAC remains a solid choice for straightforward projects in the Palo Alto area, especially when same-day availability or competitive pricing tips the scales. If your project is a standard repair or basic system replacement, either contractor will likely serve you well. For anything involving ductwork complications, multi-zone systems, or unresolved performance issues, Tempro's additional two years of experience navigating these challenges makes them the safer choice.

Frequently Asked Questions
For a straightforward system swap in a standard installation with no ductwork modifications, the experience gap matters less since both contractors handle routine replacements regularly. However, if your furnace replacement uncovers issues like cracked heat exchangers, inadequate return air, or undersized ductwork during installation, Tempro's additional diagnostic experience becomes more valuable. Ask both contractors what they check beyond the basic equipment swap.
Both companies receive consistent praise for same-day emergency response and late-night availability during heat emergencies. Customer reviews suggest comparable responsiveness for urgent situations. The decision comes down to geographic proximity—Evergreen Air HVAC may reach Palo Alto properties faster, while Tempro likely has quicker access to San Jose locations. Call both to compare actual availability for your specific situation.
Since both receive feedback about fair pricing and transparent quotes, request detailed written estimates from each company for identical equipment and scope. Compare not just the bottom line but also warranty terms, equipment tier specifications, and what's included in labor. For complex projects involving ductwork or multi-component systems, Tempro's additional experience may prevent costly callbacks, potentially offering better long-term value even at a similar upfront price.
Neither company shows red flags—both maintain required workers compensation insurance, proper licensing, and $25,000 bonds. The main consideration is that both are still building their track record compared to contractors with 10-15 years of experience. For very complex projects involving structural modifications or historic homes, you might consider also getting quotes from more established contractors. For standard residential HVAC work, both have sufficient experience and proper credentials.

How We Compare Contractors
License Verification
All license data is sourced from official California CSLB records and verified regularly.
Review Analysis
Customer reviews are aggregated from Google and analyzed to identify patterns in service quality.
Detailed Comparison
We analyze credentials, insurance, experience, and feedback to highlight meaningful differences.
Not all licensed contractors are created equal. While a valid license is the baseline requirement in California, contractors can vary significantly in experience, insurance coverage, and customer satisfaction.
- Experience matters: A contractor with 15+ years of experience has likely encountered and solved problems that newer contractors haven't faced yet.
- Workers' compensation protects you: If a contractor without workers' comp insurance has an employee injured on your property, you could be held liable.
- Reviews reveal patterns: Individual reviews can be misleading, but patterns across many reviews often reveal a contractor's true strengths and weaknesses.
- Bond amounts vary: A contractor's bond provides financial protection if they fail to complete work as agreed. Higher bonds offer more protection.
Taking time to compare contractors on these factors can save you from costly mistakes and help ensure your project is completed by a qualified professional.
