Customer Reviews
All Pro Air Systems
They worked on my heater and did a great job. Kind, thorough service, and great communication! Highly recommend:)
I was facing a real dilemma this winter. My old AC unit, which I thought was just for summer use, was suddenly struggling to keep up with the cold weather we were experiencing. The house was freezing....
Plum Hvac
Sam was great, his crew were on time and fast. Thank you all
We are very pleased with Plum HVAC. Their crew were very efficient and pleasant to work with. They explain things throughout the 2 day process. In our case it was to remove the existing gas furnace...
Sam and company has been great to work with. Response, schedule, arrival were well communicated. This is our second project with Plum.
Consider All Pro Air Systems if...
- ✓ You need a straightforward repair or maintenance service rather than a major installation, and prefer a contractor with a thorough diagnostic approach.
- ✓ Your project timeline is flexible and you're willing to work with a newer company still building its installation portfolio.
- ✓ You prioritize clear communication and professional service for routine HVAC maintenance calls during heating or cooling season.
Consider Plum Hvac if...
- ✓ You're planning a system installation such as a heat pump, ductless mini-split, furnace replacement, or ductwork project requiring permit coordination.
- ✓ You want competitive pricing backed by a contractor with enough experience to accurately estimate project scope and handle complications.
- ✓ You need assistance navigating utility rebate programs or want a contractor with proven ability to complete installations efficiently within one to two days.
- ✓ Your project involves older home challenges where twice the licensing experience matters for diagnosing hidden issues with electrical, structural, or ventilation systems.
Questions to Ask Before Hiring
- → For All Pro Air Systems: Ask for references from installation projects similar to yours, specifically how they handled permitting and any unexpected complications that arose.
- → For Plum HVAC: Ask about their current project backlog and whether your timeline fits their schedule, given their apparent volume of installation work.
- → For both: Request details about warranty coverage on equipment and labor, and ask who specifically will be performing the work on your project.
The Bottom Line
For installation projects involving heat pumps, mini-splits, furnace replacements, or ductwork, Plum HVAC is the clearer choice with twice the licensing experience, proven installation expertise, competitive pricing, and established rebate program relationships. Their four-year track record and consistent customer feedback about efficient, professional installations provides more assurance for complex projects. All Pro Air Systems may serve adequately for straightforward repairs and maintenance where their communication skills and thorough service approach shine, but their two-year tenure and repair-focused portfolio make them less suited for major installations. If you're replacing equipment or installing new systems this week, Plum HVAC's experience advantage and installation specialization reduce your risk substantially.

Frequently Asked Questions
Yes, particularly for installations. Four years means Plum HVAC has completed more installation cycles and encountered more complications like undersized ductwork, inadequate electrical service, or permit issues. All Pro's review history shows primarily service calls rather than installations, suggesting they're still building this specific expertise. For complex installations, this experience gap is meaningful.
Not necessarily for repairs and maintenance where their thorough approach and communication skills are evident. However, for major installations requiring permit coordination, rebate navigation, and handling unforeseen structural or electrical issues, their limited installation track record presents more uncertainty than Plum HVAC's four-year portfolio. Consider the complexity of your specific project.
Customer feedback suggests competitive pricing is a deliberate business strategy, with quotes often lower than multiple competitors. This could reflect efficient operations, owner involvement in estimating, or a growing company building market share. However, verify that quotes include comparable equipment quality and warranty terms, not just lower-grade components.
They're licensed to perform installations, but their customer feedback and project history emphasize service calls and repairs rather than installations. If you're considering them for an installation, ask specifically about their installation portfolio, how many similar projects they've completed, and request references from installation customers rather than service call customers.

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.
