Customer Reviews
Modern Air
We replaced all of our asbestos-wrapped ductwork and installed a new heat pump system in late October. The entire Modern Air team did a great job with this relatively large project. Andrew, the owner...
Outstanding! Professional! Efficient! Great communications! Same day service. Texts and emails confirming all communications. Installation several days later. A special thanks to Billy, Alfredo and hi...
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.
Drain Doctor
George was timely, professional, and friendly. Would definitely recommend him!
George was absolutely great! Found the issue and fixed it quickly and without over charging us.
George came out quickly and he cleared our drain. Price was reasonable and he gave us discount for flyer we received by mail.

- ✓ Your water heater needs replacement and you want a plumbing specialist handling the installation
- ✓ You value twice the licensed experience for complex plumbing diagnostics and code compliance
Questions to Ask Before Hiring
- → For water heater projects specifically, ask both contractors about their approach: Modern Air about HVAC integration considerations, Drain Doctor about plumbing system compatibility
- → If you're uncertain whether your issue is HVAC or plumbing related (some problems overlap), describe symptoms in detail and ask which trade should handle it
- → Ask about warranty coverage and how long their current technicians have been with the company
The Bottom Line
This comparison only makes sense if you're uncertain whether your problem is HVAC or plumbing related. For heating, cooling, or ventilation issues, hire Modern Air—their 17 years of HVAC expertise, transparent diagnostic approach, and strong communication make them the right choice. For plumbing problems, hire Drain Doctor—their 34 years of plumbing experience and proven emergency response capability serve you better. If you need a water heater replaced, Drain Doctor's plumbing specialization gives them the advantage. Don't choose based on years licensed alone; choose based on which trade your project actually requires.

Frequently Asked Questions
No, these are separate licensed trades. Modern Air is licensed for HVAC work only—heating, cooling, and ventilation systems. Drain Doctor is licensed for plumbing only—pipes, drains, water heaters, and sewer lines. You'll need to hire the contractor whose license matches your specific problem.
Drain Doctor is the better choice for most water heater replacements since they specialize in plumbing and water heaters connect to your home's plumbing system. While HVAC contractors like Modern Air can install basic water heaters, plumbing specialists have deeper expertise in pipe sizing, pressure regulation, and code compliance for water distribution systems.
No, Drain Doctor doesn't perform HVAC work—they're plumbing specialists. Their 34 years of experience is valuable only for plumbing projects. For heating and cooling systems, Modern Air's 17 years of HVAC-specific experience is what matters.
Based on customer feedback, Drain Doctor demonstrates faster emergency response for plumbing issues, with many customers reporting arrival within 30 minutes to a few hours. Modern Air focuses on same-day HVAC service with strong scheduling communication. However, these response times only apply to their respective trades.

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.
