Consider Breathable if...
- ✓ You need air duct cleaning, furnace cleaning, dryer vent service, or duct repair and want a contractor who specializes specifically in these systems rather than a generalist
- ✓ You value transparent communication and documentation, as customers consistently mention before-and-after photos and clear identification of additional issues like duct leaks
- ✓ You want to review how a contractor handles similar projects, with available feedback from customers dealing with allergies, post-renovation cleanup, or homes with pets
- ✓ You prefer protective service practices, as multiple customers note floor coverings and shoe removal protocols during work
Consider Gosal if...
- ✓ You have a project outside HVAC cleaning that requires general contractor capabilities, though you'll need to verify Gosal's specific experience in that area directly
- ✓ You're willing to be among the first documented customers for a contractor and can thoroughly vet their capabilities through direct references and licensing verification
- ✓ Location proximity to Union City is a priority and you want a contractor based specifically in that area rather than Oakland
Questions to Ask Before Hiring
- → Ask Gosal directly for references from HVAC or duct cleaning projects completed in the past year and follow up with those customers about service quality
- → Ask Gosal what percentage of their work involves HVAC systems and how many duct cleaning projects they complete annually
- → Ask Gosal why customer reviews are not available and request documentation of completed HVAC work, including photos or project summaries
- → Ask both companies for proof of current workers compensation and bond coverage before starting work
The Bottom Line
For HVAC and duct cleaning work needed this week, Breathable is the clear choice. Their specialization in air duct systems, documented customer feedback showing consistent professionalism and thoroughness, and transparent service practices provide the assurance you need when hiring a contractor. Gosal may be qualified, but without customer reviews, identified project types, or confirmed HVAC expertise, you'd be hiring on credentials alone and spending significant time vetting their capabilities. If you need duct cleaning, furnace service, or dryer vent work, choose Breathable. Only consider Gosal if they can provide multiple recent HVAC references and demonstrate specific experience in the work you need.

Frequently Asked Questions
The absence of reviews could reflect several scenarios: the company may work primarily through referrals or commercial contracts that don't generate online feedback, they may be a smaller operation with limited project volume, or they may not actively encourage customer reviews. Without this feedback, you'll need to request direct references and verify their HVAC experience through conversation before hiring.
Not significantly in this case. Both have over a decade of experience, which is substantial. The meaningful difference is Breathable's documented specialization in HVAC cleaning systems versus Gosal's unclear project focus. Specialization in your specific work type matters more than one additional year of general licensing.
Licensing and insurance protect you legally but don't guarantee service quality, communication, or technical expertise in HVAC systems. These credentials confirm Gosal meets state requirements, but you'll need to do additional vetting through direct references, detailed conversations about their HVAC experience, and verification of similar completed projects.
This practice suggests transparency and documentation as part of their standard service model. Customers consistently mention these photos helped identify issues like disconnected ducts or leaks they didn't know existed. For HVAC cleaning work where results aren't always visible, this documentation helps you verify the thoroughness of work performed.

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.
