De La Rosa Heating and Cooling | Certified HVAC Repair in Littlerock, CA

Yes, refrigerant leaks are a frequent issue here due to system strain and corrosion. We use electronic leak detectors and UV dye to pinpoint the exact location of the leak. Our repair involves sealing the leak, performing a vacuum test to ensure integrity, and then recharging the system with the precise, manufacturer-specified amount of refrigerant. This restores cooling efficiency and protects your compressor from damage.

The high mineral content in our local water and wind-blown dust accelerates corrosion on the delicate aluminum fins of your condenser coil. We recommend a professional coil cleaning at least once a year to remove corrosive buildup. We also offer a protective coil treatment that applies a mild acid-neutralizing solution and a thin coating to shield the metal, significantly slowing down corrosion and improving system efficiency.

Not always. Our technicians will assess the extent of the damage. Often, we can perform targeted repairs, such as straightening fins and sealing small leaks at the coil connections. If the corrosion has caused a major refrigerant leak within the coil itself, a coil replacement is usually the most cost-effective and reliable solution compared to a full system replacement, restoring your AC's performance.
