Customer Reviews
Alanis Air
Excellent install of new HVAC system - honest advice around most appropriate options, and efficiently handled
I highly recommend this company . John Alanis and his crew did an excellent job in the installation of our air conditioning and heating project .

Consider Alanis Air if...
- ✓ Your project is a straightforward replacement of an existing system without ductwork modifications or complex configuration needs, where competitive pricing is a priority.
- ✓ You're in Gilroy and prefer working with a local contractor who can respond quickly within your immediate area.
- ✓ Your HVAC system is relatively newer or standard, and you don't anticipate discovering hidden complications like outdated wiring, structural issues, or non-standard configurations during the work.
- ✓ You value direct owner involvement throughout the project and are comfortable working with a contractor still building their track record.
Consider Global Heating And Cooling Services if...
- ✓ Your home has an older HVAC system where hidden problems like deteriorated ductwork, outdated electrical connections, or non-standard installations might surface during work.
- ✓ You need complex diagnostic work for recurring problems that previous contractors haven't successfully resolved, benefiting from nine years of troubleshooting pattern recognition.
- ✓ Your project involves heat pump installation, significant ductwork modifications, or integration with unusual equipment configurations where broader experience matters.
- ✓ You're in Milpitas or the northern Santa Clara County area and want a contractor with an established nine-year track record handling emergency situations and same-day service availability.
Questions to Ask Before Hiring
- → Ask Alanis Air for references from projects completed in the past year that involved complications or unexpected issues, and how those were resolved.
- → Ask Global what their typical response time is for your specific location, since you're comparing a Gilroy-based contractor to one in Milpitas.
- → For either company, ask how they handle situations where opening up walls or accessing equipment reveals additional problems not included in the original estimate.
The Bottom Line
Global Heating And Cooling Services is the safer choice for most homeowners, particularly those with older HVAC systems, complex diagnostic needs, or projects involving ductwork and heat pumps. Their nine years of experience provides meaningful advantages in troubleshooting, handling complications, and working with varied equipment configurations. Choose Alanis Air if your project is a straightforward system replacement in a newer home with standard equipment, you're prioritizing competitive pricing, and you value having a Gilroy-based contractor for proximity and local availability. Get written estimates from both, but understand that Global's experience gap isn't just a number—it represents exposure to thousands more service calls and the pattern recognition that comes with nearly a decade of daily problem-solving.

Frequently Asked Questions
For a truly straightforward replacement with modern, accessible equipment and no surprises, the gap matters less, and Alanis Air's competitive pricing becomes more relevant. However, even standard replacements can reveal corroded connections, inadequate electrical service, or code compliance issues that require experienced judgment. Global's nine years provides more exposure to these complications and how to address them efficiently.
This is a legitimate consideration given the 20-mile distance. Alanis Air's Gilroy location gives them proximity advantage for callbacks, follow-up service, and emergency situations. Ask Global directly about their service response time to your specific address and whether they charge travel fees for your area. Same-day availability matters less if it takes significantly longer to reach you.
Two years of active licensure means Alanis Air has completed multiple installation cycles and maintains the required insurance and bonding. The greater risk is encountering an unusual problem they haven't seen before, not basic competence. If your home has standard construction and relatively accessible equipment, their track record for efficient installations is relevant. For older homes or complex configurations, Global's broader experience reduces risk.
Both companies receive feedback mentioning competitive or fair pricing, so neither appears to be premium-priced. Alanis Air's reviews specifically highlight pricing competitiveness compared to other bids, which may reflect lower overhead as a newer business. The only way to know for your specific project is to get written estimates from both, ensuring each includes the same scope of work and warranty terms.

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.
