Consider Breathable if...
- ✓ You need air duct cleaning, dryer vent cleaning, or duct sealing work where Breathable's 13 years of specialized experience directly applies
- ✓ You want documented work with before-and-after photos and detailed identification of issues like duct leaks or disconnections
- ✓ You value protective work practices like floor coverings and crew members removing shoes, which multiple customers specifically mention
- ✓ You're dealing with post-renovation cleanup, allergies, or have an older system that's never been professionally cleaned, all scenarios Breathable has documented experience handling
Consider Delcon Heating And Air Conditioning if...
- ✓ You need general HVAC repair or installation work beyond duct cleaning, though you'll need to confirm Delcon actually performs your specific service
- ✓ You're in Livermore or eastern Alameda County where Delcon is based, potentially reducing travel time
- ✓ You value a contractor with maximum longevity in the industry, as 40 years of continuous licensing demonstrates sustained business operations
- ✓ You prefer an educational service approach where technicians explain systems thoroughly, which customers specifically highlight
Questions to Ask Before Hiring
- → Ask Delcon specifically what HVAC services they perform and request examples of recent projects similar to yours, since their profile lacks this critical information
- → If you need duct cleaning, ask Delcon how many duct cleaning projects they complete annually and whether they provide before-and-after documentation like Breathable does
- → Ask both companies about their current crew composition and how long key technicians have been with the company, particularly relevant given Delcon's 40-year history
The Bottom Line
If you need duct cleaning, dryer vent cleaning, or duct system work, Breathable is the clearer choice with documented specialized experience, transparent methods, and customer feedback directly related to these services. Their protective work practices and before-and-after documentation provide accountability. Delcon's 40-year licensing demonstrates business longevity, but without documented service specialties or project history, you're essentially hiring blind. For general HVAC work beyond duct cleaning, contact Delcon to verify they actually perform your needed service and ask for recent project examples. Most homeowners needing duct-related work this week will find greater certainty and relevant expertise with Breathable.

Frequently Asked Questions
Not necessarily. Longevity shows business stability, but Breathable demonstrates focused duct cleaning expertise with documented methods, protective practices, and customer feedback specific to duct work. Delcon provides no evidence they even perform duct cleaning regularly, despite decades in business. For specialized duct work, documented recent experience matters more than license age alone.
This is a legitimate concern when choosing a contractor. While Delcon is properly licensed and insured, the absence of documented project types or service specialties means you'll need to ask directly about their capabilities for your specific needs. Breathable's transparent service list and project history provides much greater certainty about what you're hiring them to do.
Breathable clearly performs both services and has documented experience with furnace cleaning and HVAC system work. You'd need to confirm whether Delcon offers duct cleaning at all, despite their general HVAC license. Having one contractor handle related services often leads to better system diagnosis, so Breathable's documented capability in both areas is an advantage.
Yes, in meaningful ways. Breathable's customers emphasize tangible deliverables like photos, protective measures, and issue identification, suggesting a documentation-focused approach. Delcon's customers highlight explanation and education, suggesting a teaching-focused style. Both are professional, but if you want documented proof of work completed, Breathable's approach aligns better with that priority.

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.
