AC & Heat Repair in Twin Falls, ID — S&D Automotive
Twin Falls summers push past 100 degrees and Magic Valley winters get genuinely cold. Your vehicle's heating and air conditioning system isn't optional — it's a year-round necessity. At S&D Automotive on Blue Lakes Blvd, we've been diagnosing and repairing automotive HVAC systems since 1990. Whether your AC stopped cooling in August or your heater gave out on a January morning heading into Jerome, we'll find the cause and fix it right.

Signs Your AC or Heat Needs Service
HVAC problems often start subtle before they become a problem you can't ignore:
• AC blows warm air or loses cold quickly after starting
• Weak or barely-there airflow from the vents
• Unusual smell when you turn on heat or AC — musty, sweet, or like burning plastic
• Clicking, rattling, or squealing from behind the dashboard when the fan runs
• Heater only works on high settings (often a failing blower resistor)
• Windows fogging up inside despite running the defrost
• Visible refrigerant stains or oily residue near AC components under the hood
Why We Fix the Cause — Not Just Recharge the System
If your AC went warm, there's a reason. A recharge without finding the leak buys you a few weeks before it happens again. We find out why the system lost refrigerant before we do anything else. That's what we mean by showing you what we're seeing — we don't patch over a problem and send you home.
All AC and heat repairs at S&D are backed by the NAPA AutoCare 24-month/24,000-mile nationwide warranty.

Cooling System ❯
The radiator and coolant system work together with your heater core. If your engine is overheating, the heater core is often involved. See our Maintenance page for cooling system flushes.
Belt & Hose Inspection ❯
The AC compressor is belt-driven. If a belt is cracking, it's worth catching before it takes out the compressor.
Diagnostics ❯
If an HVAC warning code is triggering on newer vehicles, our diagnostic service can pull the exact fault. See our Diagnostics page.
General Maintenance ❯
Cabin air filters and coolant flushes are part of routine maintenance. See our Maintenance page.

AC & Heat Service FAQ
-
A refrigerant recharge only fixes the symptom, not the cause. If your system lost refrigerant, there's a leak somewhere. We'll perform a leak test to find it before any recharge — otherwise you'll be back in a few weeks with the same problem.
-
A properly sealed system shouldn't need recharging on any regular schedule. If you're losing refrigerant, the system has a leak. A healthy AC system can go the life of the vehicle without a recharge.
-
Almost always a failing blower motor resistor. It's a relatively straightforward fix. The resistor controls fan speed — when it fails, only the highest speed (which bypasses it) still works.
-
Yes. We have equipment for both R-134a (older vehicles) and R-1234yf (most vehicles from 2015 onward). If you're not sure which your car uses, bring it in and we'll check.
-
That musty smell is mold or mildew growing on the evaporator coil — a common issue in vehicles that run AC frequently. A cabin air filter replacement and evaporator cleaning usually takes care of it.
