Davis & Davis - Rockville's Trusted HVAC Services

This is a common problem in our area, especially during heat waves. The cause is often a refrigerant leak, a dirty or frozen evaporator coil, or a failing compressor. Our technicians will perform a thorough diagnostic to pinpoint the exact issue—whether it's recharging refrigerant, cleaning the system, or recommending a repair—to restore cool, efficient air flow to your home quickly.

Regular professional maintenance is the best defense. During our seasonal tune-ups, we check refrigerant levels, inspect lines for wear or corrosion, and ensure all connections are secure. Catching a small leak early prevents bigger, more costly repairs and keeps your system running at peak efficiency, saving you money on energy bills throughout the Rockville summer.

An air conditioner that's low on refrigerant or has a dirty coil has to work much harder to cool your home, drastically increasing energy consumption. It might still blow cool air, but not efficiently. Our comprehensive system evaluation can identify these hidden inefficiencies. We'll provide honest recommendations, from a simple cleaning and recharge to discussing if a newer, more efficient model could be a better long-term investment for your home.
