Consider Solarcraft if...
- ✓ You're installing solar panels, battery backup, or a complete renewable energy system where Solarcraft's specialized expertise directly matches your project
- ✓ Your project involves complex roof configurations, existing solar equipment, or integration with battery systems that benefit from 39 years of problem-solving experience
- ✓ You value working with an employee-owned local company and prioritize the educational approach to system design that customers consistently mention
- ✓ You need a contractor who will still be in business throughout your equipment's 25-year warranty period
Consider Downing Heating if...
- ✓ You need furnace repair, replacement, or annual heating maintenance—the core services Downing actually provides
- ✓ You're facing a heating emergency and need the kind of responsive service that Downing's customers reference in their feedback
- ✓ You're considering a heat pump purely as an HVAC replacement and want a contractor focused on heating and cooling rather than solar integration
- ✓ You prefer high owner involvement in your project and appreciate the no-pressure approach customers describe
Questions to Ask Before Hiring
- → If considering heat pump installation, ask Solarcraft about their heat pump installation volume and whether their expertise comes from the electrical/solar side or HVAC side, and ask Downing about their specific experience with heat pump technology versus traditional furnaces
- → Ask Solarcraft directly about their warranty service process and typical response times for post-installation issues, given customer reports of challenges in this area
- → Ask Downing about their experience level with any specific equipment brand or system complexity your project requires, given their shorter time in business
The Bottom Line
If you need solar panels, battery backup, or renewable energy systems, Solarcraft is the clear choice with 39 years of specialized experience. If you need furnace work or heating repairs, Downing Heating is your contractor. The only scenario requiring a real decision is heat pump installation, where you should interview both: Solarcraft brings deep electrical and integration expertise but has reported warranty service challenges, while Downing offers HVAC-focused service with high owner involvement but only four years of experience. For heat pumps, ask both about their specific installation volume with that technology and request references from similar projects before deciding.

Frequently Asked Questions
Downing Heating is an HVAC contractor specializing in heating systems—furnace repairs, replacements, and maintenance. They don't install solar panels or battery systems. If you need solar installation, Solarcraft is the specialist. The only potential overlap is heat pump installation, where both might compete.
Yes, especially for avoiding problems. Decades of experience means they've encountered every roof challenge, structural consideration, and permitting complication. They've also been in business longer than most solar warranties last, providing continuity if you need service in 15 years. Newer contractors can certainly install systems correctly, but experience reduces the risk of surprises.
Ask both companies specific questions about their heat pump installation experience and approach. Solarcraft approaches it from a renewable energy integration perspective with electrical expertise, while Downing approaches it as HVAC equipment replacement. Your choice depends on whether you prioritize integration with solar systems or traditional heating system replacement expertise.
Some customers report challenges getting timely responses for repair work after installation is complete. This is a legitimate concern for a 25-year equipment commitment. Ask Solarcraft directly about their current warranty service process, typical response times, and how they've addressed this feedback. Request references specifically from customers who've needed post-installation service.

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.
