Key Differences

The most significant difference is the ability to verify actual performance. Got Watts has 12 years of licensing experience compared to Extensive Air Conditioning's seven years, which translates to nearly double the time navigating permit processes, manufacturer relationships, and problem-solving unexpected complications during installations. More importantly, Got Watts has documented customer feedback specifically praising their HVAC installation work, detailed proposals, project communication, and professional installation crews. Extensive Air Conditioning's lack of review history means you're making a decision without knowing how they handle scheduling, communicate during projects, respond to complications, or ensure customer satisfaction. Both companies maintain identical insurance and bonding protection, but Got Watts demonstrates a proven communication system with regular project updates and transparent pricing that customers consistently mention. For HVAC work specifically, Got Watts shows evidence of completing heat pump installations, HVAC system installations, and related electrical upgrades, with customers returning for additional work—a strong indicator of satisfaction.

Ive been contracting with Extensive Air for over a year now. They are reliable and trustworthy

Consider Got Watts? if...

  • Your HVAC project requires electrical work like panel upgrades or dedicated circuits, which Got Watts handles under one contract rather than coordinating multiple trades
  • You want verifiable evidence of how a contractor communicates, manages timelines, and handles the permit process before signing a contract
  • You're considering related upgrades like EV chargers, electrical panel work, or battery backup systems that Got Watts could bundle with HVAC installation
  • You value transparent, detailed proposals and no-pressure sales processes that multiple customers have specifically praised

Questions to Ask Before Hiring

  • Ask Extensive Air Conditioning for at least three recent references for projects similar to yours, and actually call them to ask about communication, timeline accuracy, and problem resolution
  • Ask Extensive Air Conditioning how they handle permitting and inspections, and what their typical project timeline looks like from contract to completion
  • Ask Got Watts about their HVAC-specific experience and whether they employ dedicated HVAC technicians or cross-trained electricians for heating and cooling work
  • Ask both companies for detailed written proposals that specify equipment models, warranty terms, permit responsibilities, and payment schedules

The Bottom Line

For most homeowners, Got Watts is the clearer choice for HVAC work this week. Their 12 years of experience, documented customer feedback on HVAC installations, and proven communication systems provide verifiable assurance that Extensive Air Conditioning simply cannot match without customer reviews. The ability to see how past customers experienced their proposal process, installation quality, and timeline management is valuable protection for your investment. Choose Extensive Air Conditioning only if you have a trusted personal referral who can vouch for their reliability, or if their bid is substantially lower and you're willing to accept the risk of unknown service quality. Otherwise, Got Watts offers both greater experience and proven performance.

Frequently Asked Questions

Yes, when properly licensed and experienced. Got Watts holds appropriate licensing for HVAC work and has documented customer feedback specifically about heat pump and HVAC installations over their 12 years in business. Many HVAC projects require significant electrical work anyway, so a contractor with both capabilities can actually streamline the process. The customer feedback shows they complete HVAC projects professionally with proper permitting.

This could mean several things: they may serve primarily commercial clients who don't leave public reviews, they may be a smaller operation with limited project volume, or they may not actively solicit customer feedback. Whatever the reason, it creates risk for you because there's no way to verify their communication quality, timeline reliability, or how they handle problems. Ask them directly for references you can contact.

Yes, particularly for navigating complications. Twelve years versus seven years means Got Watts has handled nearly twice as many permitting processes, manufacturer warranty issues, and unexpected installation challenges like outdated electrical systems or structural complications. Their customer reviews specifically mention timeline reliability and problem-solving, which suggests that experience translates to smoother projects. For straightforward replacements the gap matters less, but most HVAC projects encounter at least some complexity.

Not without understanding what you're getting. If Extensive Air Conditioning bids significantly lower, ask why—it could reflect different equipment quality, warranty terms, or scope of work. Got Watts' customers consistently mention detailed proposals and transparent pricing, which helps you compare accurately. A lower bid from a company with no verifiable track record carries real risk of poor communication, timeline delays, or substandard work that costs more to fix later.

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.
