Alfredo was professional and courteous, and so was the previous person who came out for quote. Modern Air does a great job with their client communications, and their cost is reasonable.
Consider HVACerz if...
- ✓ You need service in central San Jose and want the shortest possible response time for a straightforward repair or standard equipment replacement
- ✓ Your project is a routine installation like replacing a furnace or AC unit with similar equipment in an uncomplicated residential setting
- ✓ You prefer working with a smaller, lean operation where you'll have direct communication with ownership throughout the project
- ✓ Your HVAC system is relatively modern and you're dealing with common failure points rather than unusual diagnostic challenges
Consider Modern Air if...
- ✓ Your home is older and may have complications like outdated ductwork, asbestos materials, or legacy equipment requiring specialized expertise
- ✓ You're dealing with an intermittent or hard-to-diagnose problem that has stumped other contractors or requires deep troubleshooting experience
- ✓ You're located in the southern part of Santa Clara County including Morgan Hill, Scotts Valley, or the Santa Cruz Mountains where Modern Air's base reduces travel time
- ✓ You value the confidence that comes with nearly two decades of field experience, particularly for a major system replacement investment
Questions to Ask Before Hiring
- → Ask HVACerz about their experience with your specific equipment brand and age, especially if your system is older than 10 years or has unusual characteristics
- → Ask Modern Air about their typical service radius and response times for San Jose locations if you're not in their immediate Morgan Hill area
- → Ask both contractors for references from projects similar to yours in scope, particularly if you're dealing with ductwork replacement or whole-system installations
The Bottom Line
For straightforward repairs and standard installations, both contractors are solid choices with similar service approaches, fair pricing, and professional communication. However, Modern Air's 17 years of experience provides meaningfully more expertise than HVACerz's 6 years when projects involve diagnostic complexity, older homes with potential complications, or specialized work like asbestos duct removal. If your project is routine and you're in central San Jose, HVACerz's location and efficient service make them a practical choice. For anything involving uncertainty, older equipment, or complex system work, Modern Air's veteran experience level offers greater confidence that complications will be handled smoothly without delays or unexpected subcontracting.

Frequently Asked Questions
For a standard replacement with no complications, both contractors have adequate experience to handle the installation competently. However, even routine replacements can reveal unexpected issues like inadequate ductwork, code violations from previous work, or structural complications. Modern Air's 17 years means they've seen these surprises more often and can adapt without delays or needing to subcontract specialized work.
Both companies receive consistent feedback for same-day availability and quick response times. HVACerz's San Jose location may provide slightly faster response if you're in central San Jose, while Modern Air's Morgan Hill base serves the southern county more efficiently. For emergency repairs of common failures like capacitors or blower motors, either contractor appears equally responsive.
Modern Air serves the broader Santa Clara County area including locations well beyond Morgan Hill like Scotts Valley. Unless you need same-day emergency service during peak demand periods, the location difference shouldn't significantly impact service quality. If your project involves diagnostic complexity or specialized work like asbestos removal, the experience advantage likely outweighs any minor travel time difference.
Ask both contractors to walk you through what they find, explain why specific repairs or replacements are necessary now versus later, and provide options at different price points. Pay attention to whether they're willing to recommend repair over replacement when appropriate. Both companies have feedback patterns suggesting they provide transparent recommendations, but you'll confirm this during your actual consultation.

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.
