When the Oklahoma "Heat Dome" pushes temperatures past 105°F, your air conditioning system isn't a comfort convenience — it's a safety system. Since 1999, Smith Brothers Heat and Air has provided OKC families with the full range of AC services they need: from an $89 diagnostic visit to a complete SEER2 system replacement.
OKC's unique climate creates specific stresses on air conditioning equipment that homeowners in more temperate regions simply don't face.
OKC regularly experiences multi-day heat events exceeding 105°F. Standard AC systems are often tested to 95°F design conditions. A system that runs fine in April can fail completely in a July heat dome. Annual tune-ups address the components most likely to fail under extreme load before the load arrives.
Oklahoma's fine red clay dust accumulates on condenser coils and acts as an insulator, reducing heat exchange efficiency. A single season of unaddressed buildup can reduce system efficiency by 15 to 30%, and the effect shows directly on your OG&E bill. Chemical coil cleaning removes it completely.
Oklahoma's violent spring storms bring lightning, power surges, and voltage spikes that routinely damage capacitors, contactors, and control boards. A pre-season tune-up catches storm damage from the previous season before it becomes an emergency on the next hot day.

Oklahoma City homes use a variety of AC system configurations. Smith Brothers services and installs all of them:
"My A/C blower motor went out and these guys had it replaced fast! I highly recommend them, very professional and upfront about the cost. I can get some much needed sleep tonight!"
"Best AC service and the best prices. I own a few properties and have used them for years. They've told me ways to fix easy stuff myself instead of trying to make the most money off me."
"Called today because our AC wasn't working. Less than 3 hours later the AC is fixed and the house is cooling. Very responsive, knowledgeable, and reasonable."
We provide 24/7 emergency AC service, 365 days a year. A real team member answers your call immediately and dispatches the nearest available NATE-certified technician. Typical response time in the OKC metro is 1 to 2 hours. During extreme heat events when call volume is high, response times may be longer — call early and we will give you an honest ETA.
We service all major brands including Trane, Lennox, Carrier, Rheem, American Standard, Goodman, and York. For installations, we primarily install Trane, Lennox, and Carrier systems — brands with the best track record for reliability in Oklahoma's extreme climate. We carry factory OEM parts for most major brands on our service trucks for same-visit repairs.
Our diagnostic fee is $89 (waived when you move forward with the repair). Common repairs range from $150 to $325 for a capacitor replacement to $450 to $900 for a blower motor replacement. We always provide a clear, itemized price before any work begins. See our full AC Repair pricing table for details.
The general rule: if your system is over 10 to 12 years old and the repair cost exceeds 50% of the replacement cost, replacement is usually the smarter financial decision. Modern SEER2 systems are 40 to 60% more efficient than units from the early 2010s — the energy savings often cover the replacement cost within 5 to 7 years. Duane Smith will always give you the honest answer, even when repair is the better choice. See our Repair vs Replace Guide.
Whether you need an emergency repair, a $89 tune-up, or a complete system replacement — Duane Smith and the Smith Brothers team are ready. Serving all OKC metro neighborhoods since 1999.
