Oklahoma winters are deceptive. Most days are mild, but when a February ice storm drops temperatures to 10°F, your furnace becomes the most important piece of equipment in your home. Since 1999, Smith Brothers has provided OKC families with reliable heating services — every brand, every system type, 24/7.
OKC's ice storms are not predictable, but they arrive every winter. A furnace that runs adequately through mild weather often fails completely when it faces sub-freezing temperatures for the first time in the season. Pre-season fall maintenance catches the failures that only show up under real cold load — before the temperature drops and the call volume spikes.
Cracked heat exchangers are the most dangerous and most commonly missed furnace failure. They allow combustion gases including CO to enter the home's air supply. Visual inspection alone cannot detect a cracked heat exchanger — camera-assisted inspection is the only reliable method. Smith Brothers performs camera inspections on every heat exchanger assessment.
A 15-year-old furnace running at 70% AFUE efficiency wastes 30 cents of every dollar spent on natural gas. Current 96% AFUE high-efficiency furnaces convert nearly every cent into actual heat. The energy savings from replacing an aging Bethany or Village home furnace often cover the replacement cost within 5 to 6 years of ONG savings alone.
24/7 emergency furnace repair for all major brands. We carry common OEM parts — ignitors, flame sensors, control boards, capacitors — for same-visit repairs. $89 diagnostic fee waived on repair.

Heating service is not just about comfort — it involves combustion, gas connections, and carbon monoxide risks that require certified, trained technicians on every call.
"My heater decided to act up right before the freeze. Smith Brothers sent someone out same day. They replaced my old thermostat and checked and changed my filters. Really fast and friendly service."
"Our heater went out on the coldest night of the year and they were there the next day. They did not stop until they had it completely fixed. They were life savers! Very professional."
"They came in and fixed my furnace quick and fast. They did not try to oversell unnecessary services. I was very pleased with their service."
Key indicators for replacement: system is over 15 years old, repair costs in the past two years exceed $500 to $600, ONG bills are significantly higher than comparable homes, or rooms never reach the thermostat set point. Repair is usually right for systems under 12 years old with isolated failures. Duane Smith provides a written honest assessment — including when repair makes more financial sense than a replacement sale. See our Furnace Repair vs Replace Guide.
Our annual fall furnace safety check starts at $89. This includes the full 21-point inspection, heat exchanger camera assessment, CO testing, and a written findings report. Ask about our HVAC Maintenance Plan which includes both a spring AC tune-up and a fall furnace check for priority scheduling throughout the year.
A yellow or orange pilot flame indicates incomplete combustion — the gas is not burning cleanly. This is a serious safety warning that may indicate a cracked heat exchanger allowing combustion gases to enter the burner area, or a gas pressure problem.
