Consider Breathable if...
- ✓ You need air duct cleaning, furnace cleaning, or dryer vent services and want a contractor with documented specialization in exactly these services rather than a general mechanical contractor.
- ✓ Transparent communication matters to you, and you value being able to verify that crews consistently arrive on time, protect your property, and provide documentation of their work.
- ✓ You prefer working with a company where multiple customers report positive repeat experiences, reducing your risk of a poor service outcome.
- ✓ Your project involves identifying hidden issues like disconnected ducts or leaks, where Breathable's pattern of thorough assessment and photo documentation provides accountability.
Consider Kell Mechanical if...
- ✓ You already have a personal referral for Kell Mechanical from someone whose judgment you trust, compensating for the lack of public customer feedback.
- ✓ Your project extends beyond HVAC cleaning into broader mechanical contracting work where a general mechanical contractor might offer advantages.
- ✓ You're located in Livermore and proximity is your primary concern, though both companies serve Alameda County.
- ✓ You're willing to be among the first customers to establish their review history, accepting higher uncertainty about crew quality and communication practices.
Questions to Ask Before Hiring
- → For Kell Mechanical: Ask for at least three recent references for projects similar to yours, with contact information you can verify, and specifically ask those references about crew professionalism and communication.
- → For Kell Mechanical: Ask how they document their work (photos, written reports) and what their process is for addressing customer concerns if issues arise after service.
- → For both: Confirm the specific crew members who will work on your project and how long they've been with the company, particularly important given Kell Mechanical's unclear track record.
- → For both: Ask about their protocol for protecting flooring and furnishings during duct work, and whether before and after photos are standard practice.
The Bottom Line
For HVAC cleaning work you need done this week, Breathable is the clearer choice. They have documented specialization in exactly the services you need, with consistent customer feedback showing reliable crews, transparent communication, and thorough work. The protective measures they take and before-and-after documentation provide accountability you can verify before hiring. Kell Mechanical may be qualified on paper, but without verifiable service history, you're accepting unnecessary uncertainty about crew quality and communication when a proven alternative exists. Unless you have a strong personal referral for Kell Mechanical, Breathable offers substantially lower risk for residential HVAC cleaning projects.

Frequently Asked Questions
Not meaningfully in this case. Both have over a decade of licensed experience, placing them in the same established contractor tier. The gap that matters is verifiable service history, not the single year of additional licensing Breathable holds. You can confirm what Breathable's crews actually do on job sites, while Kell Mechanical remains unverified despite similar time in business.
Their mechanical contractor license permits HVAC work, meeting the legal qualification threshold. However, you cannot verify whether they regularly perform duct cleaning, have specialized equipment for this work, or have crews experienced in residential HVAC cleaning specifically. Licensed capability doesn't guarantee practical expertise or service quality in this particular specialty.
This could mean several things: they may primarily serve commercial clients who don't leave online reviews, they might rely exclusively on repeat customers and referrals, or they may be less active in residential work. Without asking them directly, you're making assumptions about their service quality. For a homeowner hiring this week, this uncertainty represents real risk compared to Breathable's transparent track record.
There's no data suggesting this, and it's dangerous to assume lower visibility means lower prices. Companies without review histories may charge comparably or even more than established competitors. Get specific quotes from both contractors for your exact scope of work, and evaluate the total value including verifiable reliability, not just the bottom-line number.

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.
