Why this list matters more than Angi's "Top Pros"

If you're a Indianapolis, IN homeowner researching a hvac contractor, the question is which one will actually do the work — not who paid the most for ad placement. Building permits are the most honest signal you can get:

Every entry pulled a real permit. No self-reporting. No "premium membership" rankings. The city issued these.
Permit count is a proxy for trust. Inspectors don't keep approving a contractor's work if the work is bad — they fail it. Repeat permit-pullers have repeatedly passed inspection.
Building-permit data is public record. It can't be gamed by review-buying or pay-to-rank algorithms.

Above is the raw ranking. If you want to see what each contractor is actually working on right now — addresses, permit types, when they pulled the permit — every hvac permit is on the Indianapolis, IN permit feed.

For hvac contractors: how to land on this list

If you run a hvac business in Indianapolis, IN and don't see your company name here, it usually means one of two things:

You haven't pulled a permit in the last 180 days under your registered business name.
Your permits are filed under a homeowner's or licensee-individual's name rather than your business — which happens a lot in jurisdictions like Indianapolis, IN where the city permit system captures the licensee, not the firm.

Both are fixable. PermitGrab is built for the contractors on this list — daily permit alerts in your zip codes, owner phones where available, and a flat $149/mo with no annual contract. See how PermitGrab works for hvac contractors in Indianapolis, IN →

Frequently asked

How is this ranking calculated?

We count every hvac building permit filed in Indianapolis, IN over the last 180 days, group by contractor business name, and sort descending. No editorial weighting, no paid placements. The raw count is the rank.

Where does the permit data come from?

Indianapolis, IN's official permit portal. PermitGrab pulls daily — most permits show up within 24-48 hours of issuance. The full underlying records are visible on the Indianapolis, IN permit feed.

Is this better than Yelp or Angi reviews?

For one question — "is this contractor real and currently doing work?" — yes, by a wide margin. Reviews are great for catching catastrophic bad actors but can be gamed; permits are official-record proof of activity. Use both.

Why is contractor X not on this list?

Either they haven't pulled a permit in the last 180 days under their business name, or their permits filed under a licensee-individual's name instead. Both are common. The full search interface is on the Indianapolis, IN permit page.

I'm a hvac contractor — how do I use this?

See who's pulling the most permits in your service area, watch what work they're doing, and use the daily permit feed to spot new jobs in your zip codes the day they're filed. PermitGrab is $149/month for the full Indianapolis, IN permit feed plus 770+ other US cities.
