Edmann's Commercial Refrigeration & AC - San Juan's Emergency HVAC Services

Proper system sizing is crucial for efficiency and comfort in our South Texas climate. An oversized unit will cycle on and off too frequently, wasting energy and failing to dehumidify properly, while an undersized unit will struggle to cool your home. With over 25 years of experience, our team performs detailed calculations of your home's layout, insulation, and sun exposure to recommend a correctly sized, energy-efficient system that will provide reliable performance for years to come.

We recommend professional maintenance at least once a year, typically before the peak cooling season. Our maintenance service includes checking refrigerant levels, inspecting electrical components, cleaning critical parts, and ensuring your system runs safely and efficiently. Regular upkeep by our technicians can help prevent unexpected breakdowns during our hottest months, improve your system's lifespan, and maintain its energy efficiency, saving you money over time.

A frequent issue we see in San Juan is dirty condenser coils. The outdoor unit's coils can become clogged with dust, pollen, and grass clippings from our environment. This layer of grime acts as insulation, preventing the coil from releasing heat effectively, which forces your system to work harder and cool less. Part of our standard repair and maintenance service includes a thorough cleaning of these coils to restore proper airflow and system efficiency, a simple step that often resolves cooling problems.
