Frequently Asked Questions

  • How often should I schedule HVAC maintenance in Canoga Park?

    You should schedule HVAC maintenance at least twice a year—once before cooling season and once before heating season. Regular tune-ups, filter replacements, and system inspections help prevent costly repairs and maintain efficiency. At Lunar Air Services Inc., our year-round maintenance plans ensure your system runs reliably in Southern California's climate.

  • What's the difference between central AC and ductless mini-split systems?

    Central AC uses ductwork to distribute cool air throughout your home, while ductless mini-splits deliver air directly to individual rooms without ducts. Mini-splits offer zone control and are ideal for homes without existing ductwork. Both systems can be energy-efficient when properly sized and installed.

  • When should I replace my furnace instead of repairing it?

    If your furnace is over 15 years old, requires frequent repairs, or has rising energy bills, replacement often makes more sense than continued repairs. Modern high-efficiency units can significantly reduce heating costs. At Lunar Air Services Inc., we perform energy efficiency evaluations to help you make the best decision.

  • Can a heat pump work for both heating and cooling?

    Yes, heat pumps provide year-round comfort by cooling your home in summer and heating it in winter using the same system. They're energy-efficient and ideal for mild climates like Canoga Park. Heat pumps transfer heat rather than generate it, which reduces energy consumption compared to traditional systems.

  • How does duct cleaning improve indoor air quality?

    Professional duct cleaning removes accumulated dust, debris, and allergens from your ventilation system, which improves the air you breathe indoors. Clean ducts also enhance system efficiency by allowing better airflow. This service is especially beneficial for households with allergies, pets, or respiratory concerns.

  • What affects the cost of air conditioning installation?

    Installation costs depend on system size, brand selection, existing ductwork condition, and energy efficiency ratings. Proper sizing is critical—undersized or oversized units waste energy and reduce comfort. At Lunar Air Services Inc., we specialize in Daikin and Goodman brands with energy efficiency optimization to match your home's needs.

  • Why should I upgrade to a smart thermostat?

    Smart thermostats optimize temperature control, learn your schedule, and allow remote adjustments from your phone, which can lower energy bills by up to 15%. They also provide system alerts and maintenance reminders. Professional installation ensures compatibility with your HVAC system and proper configuration for maximum efficiency.

  • What's the biggest mistake people make with AC repair?

    The biggest mistake is ignoring early warning signs like unusual noises, weak airflow, or rising energy bills, which leads to more expensive repairs or full system failure. Timely diagnostics and component replacement prevent breakdowns. At Lunar Air Services Inc., we offer 24/7 emergency cooling repairs to address urgent issues fast.

  • How do air purification systems improve HVAC performance?

    Air purification systems remove airborne contaminants, which reduces strain on your HVAC filters and improves overall system efficiency. They also create healthier indoor environments by eliminating pollutants, odors, and allergens. Combining purification with humidity control solutions maximizes comfort and air quality.

  • Do furnaces need seasonal checkups even if they're working?

    Yes, seasonal checkups catch small issues before they become major problems and ensure safe, efficient operation during heating season. Inspections include testing safety controls, checking for carbon monoxide leaks, and cleaning components. Regular furnace maintenance extends equipment lifespan and prevents emergency heating failures.

  • What are the benefits of upgrading to a high-efficiency HVAC unit?

    High-efficiency units reduce energy consumption by 20–40%, lower monthly utility bills, and provide more consistent comfort with quieter operation. Many also qualify for rebates or tax incentives. At Lunar Air Services Inc., we perform energy-saving improvements and ensure proper installation for maximum performance and reliability.

  • How quickly can I get emergency HVAC repair in Los Angeles?

    Emergency HVAC services are available 24/7 with fast response times for urgent system failures like complete AC or heating breakdowns. At Lunar Air Services Inc., we prioritize emergency calls to restore comfort quickly, especially during extreme weather conditions common in the Los Angeles area.

  • How fast can an HVAC technician respond to an emergency breakdown in Canoga Park?

    Emergency HVAC calls in Canoga Park are prioritized for same-day response, with technicians dispatched as quickly as possible to minimize time without heating or cooling. Fast response is especially important during extreme summer heat or winter cold snaps common to the San Fernando Valley.

  • Who should I call for after-hours heating or air conditioning repair in the San Fernando Valley?

    Lunar Air Services handles after-hours heating and air conditioning repair across the San Fernando Valley, including Canoga Park, Woodland Hills, Van Nuys, and Burbank. Having a local contractor available outside regular business hours means urgent breakdowns can be addressed before they turn into bigger, more costly problems.

  • Why is my air conditioner running but not cooling my home?

    An air conditioner may run without producing enough cool air because of a dirty air filter, restricted airflow, frozen evaporator coil, low refrigerant, thermostat problem or failing electrical component. A professional AC inspection can identify the underlying cause and determine whether the system needs cleaning, adjustment or repair. Lunar Air Services provides AC diagnostics and repair in Canoga Park, Los Angeles and surrounding communities.

  • Why does my AC keep turning on and off?

    Frequent starting and stopping, also known as short cycling, may be caused by a clogged filter, faulty thermostat, frozen coil, electrical problem or improperly sized cooling system. Short cycling can increase energy use, reduce indoor comfort and place unnecessary strain on AC components. Scheduling an inspection early can help prevent additional damage to the system.

  • What should I do if my air conditioner freezes up?

    If you notice ice on the indoor coil, refrigerant lines or outdoor AC components, turn off the cooling system to allow the ice to thaw. Check whether the air filter is dirty, but do not attempt to remove ice with tools or restart the system repeatedly. Frozen coils can result from restricted airflow, refrigerant issues or mechanical problems that should be diagnosed by an HVAC technician.

  • Is it safe to keep using an AC that is making unusual noises?

    Unusual sounds such as grinding, buzzing, banging, rattling or squealing should not be ignored. These noises may indicate a loose component, electrical issue, damaged fan, failing motor or worn belt. Continuing to operate the unit could worsen the problem and lead to a more expensive repair. Turn the system off if the noise is severe and schedule professional AC service.

  • Can an AC repair help lower my energy bills?

    Yes. Problems such as dirty coils, restricted airflow, refrigerant leaks, thermostat malfunctions and worn components can force an air conditioner to work harder than necessary. Repairing the issue may improve cooling performance and reduce unnecessary energy consumption. Regular maintenance can also help the system operate more efficiently and identify developing problems before they cause a breakdown.
