Question 1

How do I know if a contractor is actually licensed in California?

Accepted Answer

Verify directly at cslb.ca.gov. Search by license number or company name. The state shows license status, classifications, bond status, and any complaints or disciplinary actions on file. If a contractor can't or won't give you their license number, that's the answer to whether you should hire them.

Question 2

Why do HVAC quotes vary so much for the same job?

Accepted Answer

Because there's no standard scope unless you require one. The lowest quote often skips permits, uses lower-tier equipment, reuses old ductwork, and skips commissioning. The highest quote usually has all the right work and a healthy margin. The middle quote is usually the most honest — but the only way to know is to compare scope line by line, not just totals.

Question 3

Is it worth replacing an HVAC system that still works but is old?

Accepted Answer

Often yes, especially for systems over 15 years old running on R-22 refrigerant or older. New systems run 30 to 50 percent more efficiently, last longer, qualify for utility rebates, and won't surprise you with a $3,000 emergency repair on a hot weekend. We do the math honestly — sometimes the answer is repair-and-wait, sometimes it's replace-now.

Question 4

What should be in a fair commercial HVAC maintenance contract?

Accepted Answer

At minimum: quarterly visits, filter and belt replacements, drain line treatment, coil cleaning at least annually, voltage and amperage logging for trending, written reports after each visit, priority response on emergency calls, and clear language on what triggers additional charges. If a contract is silent on any of these, you're buying less than you think.
