Frequently Asked Questions

Most homeowners should replace their air filter every 30 days, especially in Texas where dust, pollen, and humidity are high. Homes with pets, heavy foot traffic, or allergies may require more frequent changes. Regular filter replacements improve indoor air quality, reduce strain on your HVAC system, and help prevent unexpected AC repairs.

Absolutely. Seasonal HVAC maintenance keeps your system running efficiently and helps prevent breakdowns during peak summer heat. Routine tune-ups include cleaning, checking refrigerant levels, inspecting electrical components, and ensuring proper airflow — all of which reduce energy bills and extend the life of your AC system.

Frozen evaporator coils are usually caused by restricted airflow or low refrigerant. Turn your system off and run the fan to melt the ice. Then replace your air filter. If freezing continues, contact Century Air Solutions for professional Tomball AC repair or refrigerant diagnosis — running the unit frozen can cause major damage.

Technically, your AC can run without a filter for a short time, but it is not recommended. Operating without a filter allows dust and debris to enter your HVAC system, which can damage components and drastically reduce indoor air quality. Always keep a clean air filter installed. 

Poor airflow may be caused by a clogged filter, dirty evaporator coil, blocked ducts, or a failing blower motor. Start by replacing the filter. If airflow doesn’t improve, call Century Air Solutions for a full HVAC inspection. We diagnose issues such as blower malfunctions, ductwork restrictions, and coil blockages. 

High energy bills often come from dirty filters, low refrigerant levels, leaking ductwork, or an aging HVAC system. Regular maintenance helps identify these issues early. Century Air Solutions offers energy-efficient HVAC installations, tune-ups, duct inspections, and WiFi thermostats to help lower your monthly cooling costs.
