Why Is My A/C Blowing Hot Air on Both Sides?
Kemah · November 2026 · From our shop records
Our tech found the A/C compressor had internal wear and was not producing the pressure the system needs. Hot air from both sides sent a driver to our Kemah shop with their vehicle at 53,000 miles. The driver's side had blown hot while the passenger side stayed cold, and both sides went hot gradually, with a hissing from the front only when the A/C was on and foggy windows too. We tested the A/C system and read about 70 PSI on the low side (35 expected) and about 150 PSI on the high side (200 expected). Those readings showed the compressor could not compress and circulate the refrigerant well enough to cool.
The team recharged the A/C system. Additional system testing and a refrigerant charge check after repairs were recommended, not done on this visit.
