At a glance

How this list was built

The October 2026 snapshot uses ratings and review counts stored in the MidTen Home Pros directory. To qualify, a company had to be approved, list this service as its main trade, show a 4.5-or-higher rating, have review data, and be based in Nashville or have confirmed coverage there. Companies are ordered by review count, with rating as a tiebreaker. Review totals can change. Paid MidTen placements do not affect this order.

Hiring in Nashville

Nashville and Davidson County cover everything from older East Nashville bungalows to newer builds, so it pays to pick a company that regularly works on homes like yours.

What homeowners should ask before hiring

For heating and cooling, ask for a load calculation before any replacement quote, which equipment brands and efficiency ratings are proposed, what the labor and parts warranties cover, and whether maintenance plans include priority service in summer and winter peaks.

• Get the complete scope, exclusions, payment schedule, and change-order process in writing.
• Verify licensing when the work requires it and request current insurance directly from the provider.
• Compare at least two written proposals on the same scope; the lowest number may omit important work.
• Do not treat rating or review count as a substitute for checking recent, job-specific feedback and references.

How to read this ranking

A high review count shows a larger public feedback history; a high star rating shows the average sentiment in that snapshot. Neither proves that a company is the right fit for every project. Read recent reviews for your job type, compare written scopes, and verify details directly.

Are these the best HVAC companies in Nashville?

Does paying MidTen affect the ranking?
