Frequently Asked Questions

  • How often should you clean air ducts?

    Air ducts should be cleaned every 3 to 5 years to maintain optimal indoor air quality and HVAC efficiency. Regular cleaning removes accumulated allergens, dust, and debris that can circulate through your home. At Key Heating & Cooling, we recommend scheduling based on household conditions like pets or allergies.
  • What's included in HVAC maintenance services?

    Comprehensive HVAC maintenance includes system diagnostics, filter checks, airflow testing, cleaning components, and performance optimization. These services ensure energy efficiency, prevent costly breakdowns, and extend equipment lifespan. Regular maintenance catches small issues before they become major repairs in Owensboro's varying climate conditions.
  • How does a REME HALO air purification system work?

    REME HALO systems use advanced ionization technology to actively eliminate harmful particles, germs, bacteria, and viruses throughout your home. The system installs directly into your HVAC ductwork and continuously purifies air as it circulates. At Key Heating & Cooling, we pair installation with air quality testing for measurable results.
  • What's the warranty on new HVAC installations?

    New heating and cooling system installations come with 10-year warranty coverage on equipment and workmanship. This warranty applies to both Daikin Fit and Goodman brand systems installed by certified technicians. Proper installation and regular maintenance help ensure warranty protection remains valid throughout the coverage period.
  • When should you replace instead of repair your HVAC?

    Consider replacement when your system is over 15 years old, requires frequent repairs, or has significantly reduced efficiency. Installing a modern energy-efficient system often saves more on utility bills than continuing repairs on aging equipment. At Key Heating & Cooling, we provide honest assessments of repair versus replacement costs.
  • What are the benefits of variable speed AC systems?

    Variable speed air conditioning systems adjust cooling output to match demand, providing consistent temperatures and better humidity control. These systems run more quietly, reduce energy consumption by up to 30%, and eliminate hot or cold spots. They're particularly effective in Owensboro's humid summer conditions.
  • Can air duct cleaning help with allergies?

    Yes, professional air duct cleaning removes accumulated allergens like pollen, pet dander, mold spores, and dust mites that circulate through your home. This service significantly improves indoor air quality for allergy sufferers. Combining duct cleaning with air purification provides the most comprehensive solution for respiratory health.
  • What affects the cost of HVAC system installation?

    Installation costs depend on system size, efficiency rating, brand selection, existing ductwork condition, and home layout complexity. Variable speed and high-efficiency models cost more upfront but deliver long-term energy savings. Proper sizing is critical—oversized or undersized systems waste energy and reduce comfort.
  • How long does HVAC system installation take?

    Most complete heating and cooling system installations take one to three days depending on system complexity and home configuration. This includes removal of old equipment, installation of new units, ductwork modifications if needed, and full system testing. At Key Heating & Cooling, we ensure proper setup for optimal performance.
  • What's the biggest mistake people make with HVAC maintenance?

    Skipping annual maintenance is the most common and costly mistake homeowners make. Neglected systems lose efficiency, consume more energy, and experience premature failures that could have been prevented. Regular professional maintenance catches minor issues early and extends equipment lifespan by years.
  • Do heat pumps work well in Kentucky winters?

    Modern heat pumps perform effectively in Kentucky's moderate winter climate, providing efficient heating down to freezing temperatures. Many systems include backup heating elements for extreme cold snaps. At Key Heating & Cooling, we recommend properly sized heat pumps that match Owensboro's seasonal temperature ranges.
