Hesse Schniederjan Heat & Air | Emergency HVAC Repair in Sherman, TX

For our local climate, the most critical task is ensuring your outdoor condenser unit is clean and unobstructed. We recommend a professional spring tune-up that includes a thorough cleaning of the condenser coils and checking refrigerant levels. This prevents the unit from overheating and overworking, which are primary causes of compressor failure in the Sherman heat. Regular maintenance from our team can significantly extend your system's life.

In Sherman, where dust, pollen, and grass clippings are prevalent, we advise a visual check monthly during heavy use. Professionally, the coils should be cleaned at least once a year as part of your preventative maintenance visit, typically in the spring before the intense summer heat arrives. If your unit is near landscaping or in a particularly dusty area, it may require more frequent attention to maintain efficiency and prevent overheating.

While it's normal for the unit to be warm, it should not be excessively hot to the point you can't keep your hand on it. This is often a sign of restricted airflow due to dirty coils, low refrigerant, or an overworking compressor—common issues here. If you notice this, it's best to turn the system off and call us. Letting it run while overheated can cause serious, costly damage. Our technicians can diagnose and resolve the issue to protect your investment.
