Texas summers are hot, and heat finds the weak spots in two systems at once: the air conditioning that keeps you comfortable and the cooling system that protects the engine. We work on both in Southlake, at your home or wherever the car is parked, and test each system before we quote a repair.

The two systems share some parts and some symptoms. An electric fan that has quit can make the AC blow warm at a stoplight and make the engine run hot the same afternoon. Finding the real cause first means you pay for one repair that fixes both, instead of two guesses.

Common causes of warm air and overheating

When the AC blows warm, the usual suspects are a refrigerant leak, a compressor clutch that will not engage, a failed condenser fan or a stuck blend door inside the dash. Adding refrigerant without finding the leak only buys a few weeks. We check pressures and hunt down the leak so the repair holds.

Overheating usually comes down to lost coolant or poor circulation. Look for a sweet smell, drips under the front of the car or a low reservoir. Water pumps, hoses, thermostats and radiators are the common failures, and a thermal camera shows us where heat is building. If the gauge reaches the red, pull over and shut the engine off.

Questions

Mobile mechanic questions from Southlake.

Why does my car AC blow cold while driving but warm at stoplights?

That pattern often points to airflow across the condenser. If the condenser fan has failed, there is enough air at speed but almost none when stopped. Low refrigerant can cause something similar. We can check both at your home in Southlake. Call or text and describe when the air turns warm.

Is it safe to drive with the temperature gauge rising?

Only briefly. If the gauge climbs toward hot, switch off the AC, turn the heater to full to pull heat away from the engine, and find a safe place to stop. Running an engine hot can warp the cylinder head or blow the head gasket. Text us what happened and we will say whether to drive it.

How do I know if my water pump is going bad?

Watch for coolant drips near the front of the engine, a crusty trail below the pump, a whining or grinding noise, or an engine that runs hotter than normal. On some engines the timing belt drives the pump, so the two are often replaced together. Call or text if you notice any of these.

Should I get my AC checked before summer?

If it took longer than it used to for the cabin to cool down last year, or the compressor cycled on and off a lot, a spring check can catch a slow leak or a weak part early. We do the check at your home. Send us a text to set up a time.
