Air Conditioning Repair

When Tulsa's August heat hits 100°F with 75% relative humidity, a broken air conditioner is an urgent emergency. Ironclad's NATE-certified technicians arrive fully equipped in mobile warehouse vans stocked with 90% of universal replacement components — including high-temp capacitors, heavy-duty contactors, hard-start kits, and TXV valves. We don't guess or push replacements. We charge an upfront flat $89 diagnostic fee, pinpoint the root electrical or mechanical malfunction using digital manifold gauges and thermal cameras, and present you with fixed-quote options before touching a screw.
📍 Tulsa & Green Country Climate Insight:

AC Replacement & Installation

An oversized or poorly matched AC short-cycles, failing to pull Tulsa's thick humidity out of your home. An undersized unit runs continuously without ever reaching your thermostat setpoint. At Ironclad, we perform certified Manual J engineering load calculations on every home before recommending a system. We install premium high-efficiency variable-speed and two-stage systems that deliver whisper-quiet comfort, dramatic 30–45% electricity savings, and 10-year parts & labor warranties. Plus, our team handles all PSO Oklahoma electric rebate filings directly for you.
📍 Tulsa & Green Country Climate Insight:

Oklahoma's climate requires high latent heat removal (dehumidification). We specialize in two-stage and variable-capacity inverter compressors engineered specifically for humid regions.

What's Included In This Service
Certified ACCA Manual J load calculation for exact tonnage sizing
Authorized installer for Trane, Carrier, and Lennox Elite systems

Furnace & Heating Repair

When an Oklahoma polar vortex sweeps through Green Country, you need heating that works reliably without carbon monoxide hazards. Our certified technicians perform comprehensive electronic combustion safety testing, electronic flue gas analysis, and microscopic heat exchanger inspections. From faulty hot surface silicon nitride ignitors and clogged pressure switches to noisy inducer fan assemblies, we restore safe, steady warmth to your family with guaranteed parts and clean workmanship.
📍 Tulsa & Green Country Climate Insight:

Oklahoma winter freezes often cause condensation lines in high-efficiency 90%+ condensing furnaces to freeze, triggering safety pressure switch lockouts. We insulate and safeguard your discharge lines.

What's Included In This Service
Digital combustion and carbon monoxide safety verification
Hot surface ignitor and flame sensor cleaning and replacements
Draft inducer draft motor and pressure switch troubleshooting
Blower wheel static pressure balancing and ECM motor service

96%+ AFUE Efficiency
Financing from $79/mo

Furnace & Heat Pump Replacement

Replacing an aging 65% AFUE gas furnace with a modern modulating 96%+ AFUE system means 96 cents of every dollar goes directly into warming your living spaces rather than escaping up the chimney. We offer dual-fuel hybrid systems combining high-efficiency electric heat pumps with natural gas furnace backups — automatically selecting the cheapest heating fuel based on outdoor Tulsa temperatures.
📍 Tulsa & Green Country Climate Insight:

Dual-fuel hybrid heating is ideal for Tulsa: heat pump heating during 45°F–60°F autumn/spring days, switching seamlessly to gas during sub-freezing January Arctic blasts.

What's Included In This Service
Multi-stage and modulating gas valves for even room temperatures
Quiet ECM variable-speed blower motors with continuous air filtration
Double-walled stainless steel secondary heat exchangers
Oklahoma Natural Gas (ONG) energy efficiency rebate assistance

Indoor Air Quality & Purification

Oklahoma ranks among the highest states for allergy and asthma triggers due to heavy spring tree pollen, ragweed, and mold spores trapped inside sealed homes. Standard 1-inch fiberglass filters only protect the furnace blower — they do not cleanse the air you breathe. Ironclad installs medical-grade whole-home indoor air quality solutions that destroy airborne viruses, bacteria, VOCs, pet odors, and allergens in every room of your house.
📍 Tulsa & Green Country Climate Insight:

Tulsa homeowners often battle both spring pollen count spikes and summer indoor mold proliferation when humidity stays above 55%.

What's Included In This Service
REME HALO® & HALO-LED™ active hydrogen peroxide purification
4-inch to 5-inch MERV 11–16 whole-home media filter cabinets
Dual-lamp UV-C germicidal coils for evaporator mold prevention
AprilAire whole-home bypass & steam humidifiers for dry winter air
Quiet whole-home central dehumidification systems

Custom Duct Assessment

Ductwork Repair & Deep Cleaning

According to the Department of Energy, the average residential duct system loses 25% to 40% of conditioned air through loose joints, torn flex ducts, and attic disconnects. This forces your equipment to work twice as hard while pulling hot, dusty attic air into your bedrooms. Ironclad inspects your entire duct network with digital anemometers and thermal imaging, sealing leaks, re-engineering restricted supply runs, and vacuuming decades of dust, pet dander, and debris.
📍 Tulsa & Green Country Climate Insight:

Many 1970s–1990s homes in South Tulsa and Midtown have undersized return air plenums that starve modern high-SEER variable blowers.

What's Included In This Service
High-power HEPA-filtered negative air vacuum duct scrub
Static pressure airflow testing and damper balancing
R-8 insulated flex duct replacement and mastic paste sealing
Return air drop enlargement for proper CFM system breathing
Camera duct inspections before and after cleaning

When to Shut Off Your HVAC & Call Us Immediately

Outdoor Unit Humming But No Fan

Indicates a failed dual-run capacitor. Running power without the fan will overheat and destroy the expensive compressor in under an hour.

Ice on Copper Lines or Air Handler

Never chip the ice. Switch thermostat from COOL to OFF, fan to ON, and call us to detect the underlying refrigerant leak or airflow blockage.

Burning Electrical or Sulfur Smells

Can indicate melting wire insulation, seized blower motors, or gas valve issues. Turn off the master circuit breaker and call dispatch immediately.
