We get called for second opinions constantly, and we're often the ones telling people their system is fine. These are the seven patterns that come up most — and the exact questions that stop them cold.
The tactics
1. The rock-bottom or free tune-up that always finds a catastrophic problem 2. 'Cracked heat exchanger' with no photo, no combustion analysis, and an immediate red tag 3. Refrigerant scare: 'your system uses R-22, it's illegal now' (it isn't illegal to service) 4. A price that drops sharply the moment you say no 5. A manager who 'happens to be nearby' and shows up to close 6. No model numbers, no load calculation, no permit on the proposal 7. Pressure to sign tonight for a rebate that actually runs all season
Questions that end the pitch
- Can you show me a photo or video of the failure? - What's the model and serial, and how old is this equipment? - Did you run a Manual J load calculation for the replacement size? - Is the permit included in this price? - Can I have the written diagnosis and take 48 hours? An honest contractor answers all five without flinching.
When replacement genuinely is the right call
15+ years old with a failed compressor. A truly cracked heat exchanger, verified with a camera and combustion readings. R-22 systems with a major leak. Repair costs exceeding half the price of new equipment. We'll tell you that plainly — and we'll tell you when it isn't.
Frequently asked questions
Should I get a second opinion on an HVAC quote?+
On any major repair or a full replacement, yes. A reputable company won't be offended.
Is a cracked heat exchanger always dangerous?+
A genuine crack is serious, but it must be verified visually or with combustion testing — not just asserted.
Do you charge for second opinions?+
We charge a flat diagnostic fee and it's credited toward any repair we perform.
