How to evaluate 3rdGen Heating & Cooling

Before hiring 3rdGen Heating & Cooling for general contractor work in Berkeley, take a few minutes to verify their qualifications and confirm they are the right fit for your project. The right general contractor for one homeowner may not be the right fit for another, so do the diligence up front.

Verify licensing and insurance

Confirm that 3rdGen Heating & Cooling carries an active CA contractor license appropriate for the scope of work, plus general liability and workers’ compensation coverage. Ask for the license number and look it up on the state board website. A general contractor that hesitates to share these details is a red flag, regardless of how favorable their reviews look.

Get a written, itemized quote

Request a detailed written estimate that lists materials, labor, permit fees, timeline, and payment schedule. Itemized quotes make it possible to compare 3rdGen Heating & Cooling side-by-side with other general contractor options in Berkeley, and they protect you from scope creep once the work begins.

Ask about project experience

Ask 3rdGen Heating & Cooling how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a general contractor actually shows up.
