High OG&E bills. A breakdown in a July heat dome. Cedar Fever choking your air handler. An aging system that keeps costing you. A commercial building without reliable heating. Every HVAC problem OKC homeowners and businesses face has a specific, proven solution. Here is where to find yours.
Jump straight to the solution that matches your situation: or scroll down for the full picture.
Every HVAC problem listed on this page happens everywhere. But in Oklahoma City, several of them happen harder, faster, and more often than in most of the country. Knowing which Oklahoma-specific factor is driving your problem is the difference between a temporary fix and a permanent solution.
Your system is running but the house isn't right: these are the most common OKC HVAC complaints and each has a specific cause.
Your system is on, the fan is blowing, but the air isn't cold. Likely cause in OKC: failed capacitor, refrigerant leak, or Red Dirt-fouled condenser coil that can't transfer heat.
$89 diagnostic: waived on repair. We identify the exact failure, present a clear upfront price, and fix it with OEM parts on the first visit in most cases.
AC Repair Services →In OKC's 105°F heat dome, a system sized for 95°F design conditions will run continuously and still fall short. Often means the system is undersized for your actual load, or coils are fouled.
We calculate your home's actual cooling load to determine if the system is correctly sized, and perform a chemical coil wash to restore full heat transfer efficiency.
Book $89 AC Tune-Up →Furnaces that run fine through mild weather often fail completely when they face sub-freezing temperatures for the first time in the season. This is a family safety emergency.
A real team member answers at any hour. Stocked service trucks reach most OKC addresses in 1–2 hours. We carry ignitors, flame sensors, and control boards for same-visit repairs.
Emergency Heating Service →If your OG&E bills have climbed steadily or you're spending more on repairs than a new system would cost, there's a clear path forward.
A dirty condenser coil, a low refrigerant charge, a clogged filter, or an aging low-SEER system can add $80–$150/month in wasted energy: often without any obvious symptom other than the bill.
Our $89 spring tune-up includes a chemical coil wash, refrigerant pressure check, and a written efficiency report. We'll tell you exactly what your system is costing you monthly and what a replacement would save.
Book $89 Tune-Up →When a 12-year-old system requires its third repair in two years, each fix is buying diminishing time on equipment running at 60% efficiency and borrowing against its remaining useful life.
Duane Smith provides a written 3-year cost comparison: continued repairs vs. a new system on financing. For many OKC homeowners, the monthly financing payment costs less than their average annual repair bill divided by 12.
View Replacement Options →AC failures don't happen in mild April weather: they happen on the hottest day of the year when emergency call rates are high and wait times are long.
Two annual tune-ups plus priority emergency scheduling all year. Plan members move to the front of the dispatch queue during heat domes, ice storms, and storm surge events.
See the Maintenance Plan →OKC's specific air quality challenges: Cedar Fever, Red Dirt particulate, and lake-area humidity: require targeted IAQ solutions, not generic advice.
Eastern Red Cedar pollen season runs December through March in OKC. Standard 1-inch MERV-8 filters don't capture Cedar pollen: it recirculates through the system continuously.
iWave ionization neutralizes Cedar pollen particles before they recirculate. A 4-inch MERV-13 media filter captures what remains. Most OKC Cedar Fever households report significant indoor relief.
Air Purifier Installation →Homes near Lake Overholser, the Canadian River (Norman), or any OKC neighborhood with high spring/summer humidity are at elevated risk of mold colonizing the evaporator coil inside the air handler.
UV-C light installed at the evaporator coil destroys mold DNA at the cellular level, preventing colonization. Critical for Norman, Bethany, and all lake/river-adjacent OKC neighborhoods.
UV-C Purifier Installation →Oklahoma's Red Dirt particulate infiltrates homes through leaky ductwork, bypasses thin MERV-8 filters, and recirculates continuously. More common in Mustang, Yukon, and open-terrain western OKC suburbs.
Upgrading to a 4-inch MERV-11 to MERV-13 media filter housing captures Oklahoma's fine clay particulate without restricting airflow. Lasts 6–12 months vs monthly replacement.
Air Filtration Upgrade →A large share of OKC's housing stock was built in the 1990s and 2000s: meaning original HVAC systems are now 20–30 years old and entering critical decision territory.
Edmond, Moore, Yukon, and North OKC saw massive residential construction from 1990 to 2005. Those original HVAC systems: if never replaced: are now operating at 40–60% efficiency of a current SEER2 system. If your Edmond or Moore home still has its original system, the question isn't whether to replace: it's when, and how to finance it.

See Financing Options →Qualifying heat pump installations are eligible for up to $2,000 in federal tax credits under IRA Section 25C: but most OKC homeowners don't know which systems qualify.
We identify qualifying systems at the estimate appointment and explain how to claim the credit at tax filing. Plus OG&E utility rebate programs for high-efficiency upgrades.

The problem at the top of this page is a $40 billion national HVAC industry where the incentive is to upsell, not to solve. Duane Smith built Smith Brothers on a different model: diagnose accurately, price transparently, and fix it right the first time.
"My AC went out during the hottest week of the year. Smith Brothers had someone out within 2 hours. Fixed on the first visit. Professional, upfront about cost, and didn't try to oversell anything."
"I was paying too much on OG&E every month and didn't understand why. Smith Brothers did an assessment, found the issue (coils were loaded with red dirt), and my bill dropped within one month of the service."
"Duane's team replaced our entire HVAC system. The six-man crew arrived at 9am and left at 4:30pm: complete installation. Not exaggerating when I say it was a life-changing experience. Go with Smith Brothers."
Call 405-524-1366 and describe what you're experiencing: unusual noises, comfort issues, high bills, or a complete failure. Our team will ask a few questions to determine whether a diagnostic visit or emergency dispatch is appropriate. The $89 diagnostic fee is waived when you move forward with the repair.
The general guideline: systems under 10–12 years old with repair costs under 50% of replacement cost are usually better repaired. Systems over 12–15 years old with rising bills, repeated repairs, or failing comfort are usually better replaced. Duane Smith provides a written assessment with the honest recommendation: including when repair is the right answer even though a new system sale would be more profitable for us.
Yes. Smith Brothers provides complete residential and commercial HVAC solutions across the OKC metro. Commercial services include RTU repair and installation, commercial heating, property management programs, and new construction coordination. The same local accountability and upfront pricing standards apply to every commercial call.
The most common OKC-specific HVAC problems Smith Brothers solves every season: (1) Red Dirt condenser coil fouling reducing efficiency and driving up OG&E bills, (2) Capacitor failures following spring lightning surge events, (3) Cedar Fever pollen overloading standard filters December through March, (4) Furnace failures during the first ice storm of the season after summer dormancy, (5) 1990s-era systems in Edmond and Moore reaching end of life after 25+ years.
