HVAC is one of the largest discretionary purchases a homeowner makes, and quality varies wildly. Use this list before you hand over a credit card.
The 10 Questions
- Are you licensed with the Arizona Registrar of Contractors, bonded and insured? Ask for the ROC number and verify it yourself on the ROC website. Ask for a certificate of insurance.
- Is the price flat-rate and in writing before work starts? Hourly-plus-parts invites surprises.
- Will you show me the failed part and the measurement that condemned it? A good tech is happy to.
- For replacements: will you perform a Manual J load calculation? If they size by "we'll match what's there," walk away.
- Do you pull the city permit? Permitted, inspected work protects resale value and warranty.
- What exactly does the warranty cover, and for how long? Get parts and labor terms separately, in writing.
- Are your technicians background-checked, drug-tested and EPA 608 certified?
- Do you charge extra for nights and weekends? Know before the emergency.
- Can you provide local references in my city? Not statewide — your city.
- Is the technician paid commission on sales? It legitimately changes recommendations.
Red Flags
- Refusing to give any price range over the phone
- Condemning a system without measuring anything — no gauges, no meter, no static pressure
- "Today only" pricing and high-pressure financing paperwork
- Recommending a refrigerant top-off with no leak search
- Scare tactics about carbon monoxide with no combustion analyzer in hand
- Cash-only, no written invoice, unmarked vehicle, no ROC number
Green Flags
- Photos and measurements included in a written diagnostic report
- Repair option presented alongside replacement, with honest math
- Free second opinions
- Named technician, shoe covers, drop cloths, cleanup
- Real reviews that mention specific technicians and specific cities
