Choosing an HVAC Contractor: Questions That Matter

Two quotes for "a new system" can mean completely different work. The difference shows up years later in your comfort and your bills. A few questions tell you which kind of contractor you're talking to.

Questions worth asking

• "Will you run a load calculation?" If sizing comes from your square footage or your old unit, you'll likely inherit the same oversized, humidity-prone setup.
• "Will you check my ductwork?" New equipment on bad ducts underperforms. The ducts should be part of the conversation.
• "Is the price flat-rate and in writing before work starts?" You should know the number up front — no mystery diagnostic surprises.
• "Are you licensed and insured?" In Alabama, ask for the license number.
• "What happens if there's a problem after install?" A real company stands behind the work.

Red flags

High-pressure sales, a push toward the biggest unit, vague pricing, or a refusal to look at the whole house are all signs to keep looking. The goal isn't the cheapest quote or the biggest box — it's the system that's right for your home and a team that will stand behind it.
