Get the Answers You Need for Optimal Comfort

Your HVAC Questions, Clearly Answered

  • How often should I have my HVAC system serviced?

    We recommend having your HVAC system serviced at least twice a year—once in the spring for your air conditioning and once in the fall for your heating. Regular maintenance helps keep your system running efficiently, prevents costly breakdowns, and extends the life of your equipment.

  • What are the signs my air conditioner or furnace needs repair?

    Common signs that your HVAC system needs repair include:


    • Inconsistent temperatures
    • Unusual noises (grinding, banging, or squealing)
    • Weak airflow
    • Higher-than-normal energy bills
    • Frequent cycling on and off
    • Unpleasant odors If you experience any of these issues, it’s best to contact us for a professional inspection.

  • How do I know if I need to replace my HVAC system or just repair it?

    If your system is over 10-15 years old, requires frequent repairs, or your energy bills have dramatically increased, it may be time to consider a replacement. Our technicians can evaluate your current system and recommend the most cost-effective solution, whether it’s a repair or a new installation.

  • What should I consider when buying a new HVAC system?

    When purchasing a new HVAC system, you should consider the following:


    • Energy efficiency: Look for systems with high SEER ratings (Seasonal Energy Efficiency Ratio) to save on energy costs.
    • Size of the unit: Proper sizing is crucial for optimal performance. A unit too small won’t cool or heat your home effectively, and one too large will cycle on and off too frequently.
    • Type of system: Choose between central air, ductless mini-splits, or heat pumps based on your home’s needs. Our experts will guide you in choosing the best system for your space and budget.

  • Do you offer emergency HVAC repair services?

    Yes, at Cosmic HVAC Inc., we offer 24/7 emergency HVAC repair services. We understand that heating and cooling issues don’t always happen during regular business hours, and we’re committed to restoring your comfort as quickly as possible.

  • How can I improve my indoor air quality?

    Indoor air quality can be improved through regular duct cleaning, using high-quality air filters, installing air purifiers, and maintaining proper humidity levels. Our team can recommend solutions to reduce allergens, dust, and pollutants in your home.
