ER Block Heating Air Conditioning and Refrigeration - Corona's Trusted HVAC Services

This common issue, often called 'thermal stratification,' is frequently due to an imbalanced HVAC system or leaky ductwork in the attic. At ER Block, we perform a detailed airflow analysis and duct inspection to identify leaks or restrictions. Solutions can include sealing your duct system, adjusting dampers, or recommending a zoning system to independently control temperatures on different floors, ensuring even comfort throughout your home.

Absolutely. Leaky ducts force your system to work much harder to heat or cool your home, wasting conditioned air into unused spaces like attics or crawl spaces. This inefficiency can increase your energy bills by 20% or more. Our technicians use specialized tools to locate and seal these leaks, restoring proper airflow to your living spaces, improving comfort, and reducing your monthly utility costs.

Our preventative maintenance visit is designed to catch small issues before they become big problems, especially important with our local dust and heat. We thoroughly clean coils and components, check refrigerant levels, inspect electrical connections, test safety controls, and assess the entire duct system for leaks or damage. This service helps maintain efficiency, prevent unexpected breakdowns during peak seasons, and extends the life of your system.
