Smith Brothers Heat and Air in Oklahoma City repairs and installs air conditioning, furnaces, and heat pumps. We run a Manual J load calculation, set the refrigerant charge, and measure static pressure instead of guessing tonnage.

Duane Smith's shop at 1724 Linwood Blvd has served Oklahoma City since 1999, engineering for brutal summers, red-dirt coils, and historic homes in Heritage Hills, Mesta Park, and The Paseo. Licensed, bonded, and insured, NATE- and EPA-certified, we dispatch 24/7 emergency calls with upfront prices and a 4.7 Google rating from 146 reviews.

What we value

How every job gets run

  • Straight answers

    Repair or replace, and the math behind whichever one we recommend. We don’t quote a system you don’t need, and we say so when a repair is the smarter money.

  • A guarantee that means something

    Two years on workmanship, printed on the invoice. If something we touched acts up, we come back and make it right at no charge — no fine print about it.

  • Respect for the house

    Drop cloths, shoe covers, and the old equipment hauled out before we leave. You should notice the house is comfortable again, not that we were ever in the basement.

  • 4.7★ 157 Google reviews
  • 13 areas served
  • ✓ Licensed & Insured
  • ✓ Same-Day Service

The crew

The people who actually show up

No subcontractors, no rotating strangers. When Smith is on the schedule, one of these three is at your door — in uniform, in the window we texted.

    Locally owned, honest, and hard working. I've found my new HVAC company for personal and business use.

  • Candy Nunez 2 months ago

    Mr. Duane was super prompt about scheduling a time to come out on the same day to check our thermostat. Mr. Nicholas was our tech and he was great, too! He was very efficient and told us what was wrong with our unit.

  • Matthew Aur 3 months ago

    We couldn't be happier with the work Smith Brothers Heat and Air did for us. This was a custom job with significant challenges once things were opened up, but they stayed calm, problem-solved, and delivered a flawless result. What impressed me as well was their integrity in honoring their original estimate even though the job clearly became more complicated. The crew was professional, respectful of our home, and did the job right. I'd highly recommend them to anyone looking for a trustworthy HVAC company.
