Said It Here

Are commercial HVAC quotes and unit sizes reasonable?

Determining whether a contractor quote and equipment size are legitimate is difficult when faced with high costs like ten to twelve thousand dollars for a cassette or twenty-four thousand for a multi-head system. Without clear benchmarks for capacity and pricing, it is impossible to know if the proposal is fair or if the recommended unit is appropriate for the space.

Does around $10k–$12k installed sound reasonable for a 10kW ceiling cassette?source ↗

Is 10kW appropriate for a 37-seat restaurant, or would you normally recommend a different capacity?source ↗

Being quoted around $24k for a 5 head Mitsubishi 4 ton unit to be installed in a split level in central nj. Being told it is a 2-3 day job. Does this seem like a legit quote?source ↗
