Customer Reviews
All About Air
Chris is always a pleasure to work with, and we have had him come to the house now for quite a few years.
Another great maintenance job.
Love the family owned business All About Air. Over the years I have used their services in 2 homes. They installed new AC & heaters and continue to do annual check up services. Christine (wife/owner)a...
Alpine Mechanical Service Company
Very open and professional also for last minute things. Great!
So professional and cordial.
Consider All About Air if...
- ✓ Your HVAC emergency cannot wait days for service, and you need confidence the company will respond quickly when your system fails during extreme weather
- ✓ You value clear explanations about what's wrong with your system and want technicians who take time to walk you through repair options and costs
- ✓ You prefer working with a company where you can verify how they treat customers, handle installations, and maintain long-term service relationships
- ✓ You want a contractor who remembers your equipment history and provides continuity across annual maintenance visits and future repairs
Consider Alpine Mechanical Service Company if...
- ✓ You specifically need a contractor in Livermore rather than Hayward and location proximity is your primary concern
- ✓ You're willing to be among the first customers to publicly document their service experience with a long-licensed contractor
- ✓ The additional 19 years of licensure history provides sufficient confidence despite the absence of verifiable customer feedback
- ✓ You have direct referrals from people you trust who have used Alpine and can personally vouch for their work quality and service approach
Questions to Ask Before Hiring
- → Ask Alpine directly why they lack customer reviews and request references from at least three recent projects similar to yours, including contact information you can verify
- → Ask Alpine about their typical response time for emergency service calls and whether they offer same-day availability during peak seasons
- → Ask Alpine how long their current service technicians have been with the company and who will specifically handle your project
- → Ask both companies for a detailed written estimate including equipment specifications, warranty terms, timeline, and what happens if issues arise during installation
The Bottom Line
All About Air is the more verifiable choice for most homeowners who need HVAC service this week. Their 18 years of veteran experience is more than sufficient for complex diagnostics and system installations, and their documented track record of same-day emergency response, clear communication, and relationship continuity directly addresses what matters most when your heating or cooling fails. Alpine's additional 19 years of licensure demonstrates stability, but without customer feedback to confirm service quality or responsiveness, you're making a decision blind. Choose All About Air unless you have direct personal referrals vouching for Alpine's work. If you're considering Alpine, insist on speaking with recent customers before signing a contract—their responses will tell you everything the missing reviews cannot.

Frequently Asked Questions
More years licensed suggests Alpine has navigated more industry changes and building code updates, which can translate to deeper troubleshooting expertise. However, 18 years also represents veteran-level experience—All About Air has handled nearly two decades of equipment evolution and complex repairs. Without customer feedback confirming how Alpine applies that experience, you can verify All About Air actually delivers thorough diagnostics and professional service, which matters more than years on paper.
Possible explanations include primarily serving commercial clients, relying entirely on word-of-mouth referrals, or simply not actively managing their online presence. None of these reasons are disqualifying, but they do mean you'll need to request direct references and verify their track record yourself. For a contractor handling emergency repairs or expensive system replacements, having no way to assess customer experiences creates real uncertainty.
Family operations can mean greater owner accountability and relationship continuity—customers specifically mention All About Air remembering them across visits. The limitation would be capacity during peak seasons, though their documented same-day service availability suggests they manage demand effectively. Ask both companies about their crew size and whether they subcontract work, as this affects scheduling flexibility regardless of business structure.
Location matters for emergency response time and service call fees, but both Hayward and Livermore serve the broader East Bay region. All About Air's documented pattern of same-day emergency availability may outweigh a few miles of distance. Ask both companies directly about their response time to your specific address and whether they charge travel fees, rather than assuming proximity guarantees faster service.

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.
