This page is for San Antonio homeowners with a Daikin furnace that won’t start, won’t stay lit, makes noise, or pushes cold air. You’ll find the specific failure modes we see on Daikin equipment here, what repairs actually cost in this market, and how we handle the job from first call to final test. Andre Fuller and our crew have been turning wrenches on Daikin systems in San Antonio for years, and we’ll tell you straight what your furnace needs and what it costs before any work begins.

How Daikin Products Fail – and How We Fix Them

Daikin builds solid furnaces, but every brand has patterns. Here’s what we actually see on Daikin units in San Antonio homes:

• DM96VC and DM97MC pressure switch trips. These modulating furnaces rely on pressure switches to confirm the draft inducer is pulling combustion gases correctly. In San Antonio, where furnaces sit idle for eight months and then fire up on a 35-degree January morning, dust and spider webs settle in the pressure switch tubing. The switch opens, the board locks out, and you get no heat. We clean or replace the switch and verify the inducer is pulling proper inches of water column.
• DBG and DCG gas valve failures on older Daikin packages. The gas valve controls fuel flow to the burners. On Daikin’s packaged gas-electric units that are 10 to 15 years old, we see valves that click but don’t open, or open slowly and cause delayed ignition. The fix is a replacement gas valve, and we typically install the OEM Daikin part to maintain warranty coverage if the unit still has coverage left.
• Ignitor failures on Daikin 80% and 90% furnaces. Daikin uses silicon nitride ignitors, which are more durable than the old silicon carbide style, but they still crack eventually. The symptom is the furnace tries to start, the blower runs, but no flame. This is one of the most common Daikin furnace repairs in San Antonio, and it’s usually a $200 to $400 fix depending on the model. We replace it with an OEM ignitor when possible.
• DM80 and DM96 control board faults. Daikin’s modulating furnaces have complex control boards that manage variable-speed blowers and modulating gas valves. A voltage spike from a San Antonio thunderstorm (we get plenty) can fry the board. The furnace may run the blower constantly, show an error code, or fail to start at all. We diagnose the board directly, check for any underlying wiring issues like a grounded thermostat wire, and replace the board if it’s truly dead.
• Heat exchanger concerns on older Daikin furnaces. Not an enormous failure rate on Daikin compared to some brands, but on units that are 15-plus years old, hairline cracks can develop. If we suspect it during a tune-up or repair, we run a combustion analysis and a visual inspection with a scope. If the heat exchanger is compromised, we’ll show you photos of exactly what we found and give you an honest recommendation: repair versus replacement. Safety comes first on this one. Carbon monoxide is invisible, and we don’t gamble with it.

Our Daikin Furnace Repair Process

Here’s exactly what to expect when you call Halden Heating and Air San Antonio for Daikin furnace repair:

   Book online or call. You reach a live person, not a phone tree. We schedule a technician and send a live arrival time you can track on your phone, plus the tech’s name and photo before they show up.

   Written price before work. You get a flat written price for the repair before any part is ordered or any tool comes out. That price includes the part, the labor, and the guarantee. No surprises at the door.
4. 4
   Parts decision. If your Daikin still has warranty coverage, we use OEM Daikin parts to keep that warranty intact. If it’s out of warranty and an OEM part is on backorder, we’ll talk through a quality aftermarket option and tell you the trade-off before you decide.
5. 5
   The repair and test. We complete the repair, then run a full start-up sequence, check temperature rise, verify flame signal, and make sure the furnace cycles properly before we leave.
