Fast,  affordable HVAC service

"Justin responded immediately to my call when my heat went out. He set an appointment time and was early. He very quickly found an obscure problem - so he is clearly very talented. The part that needed replacing wasn’t in Gainesville so he drove (same day) to Lawrenceville to get the part. Then back to my house to install it. I got picture and video updates. His knowledge, compassion and willingness to go the extra miles have made a loyal customer. I will always use Justin’s company.  (Oh!!! And the price was so affordable. Usually when you see the bill you cringe. This time I cheered.)"

Ductless Mini Split Installation & Repair

Looking for an energy-efficient way to heat and cool your home without ductwork? Ductless mini split systems offer flexible, cost-effective comfort for individual rooms, additions, garages, basements, and older homes.

At ACL Mechanical, we provide professional mini split installation, repair, and maintenance services to help homeowners enjoy precise temperature control and improved energy efficiency.


What Is a Ductless Mini Split System?

  • Areas with inconsistent temperatures

Benefits of Mini Split Systems

  • Improved indoor comfort


Mini splits are an excellent solution for homeowners who want targeted comfort without replacing their entire HVAC system.


Our Mini Split Services Include:

  • Ductless mini split installation
  • Mini split repair and troubleshooting
  • Seasonal maintenance and tune-ups
  • Multi-zone system installation
  • System upgrades and replacements


Whether you need to cool a single room or add zoned comfort throughout your home, ACL Mechanical can design and install the right ductless mini split system for your needs.

Residential HVAC Frequently Asked Questions

  • How often should I schedule residential HVAC maintenance?

    We recommend scheduling residential HVAC maintenance twice per year — once in the spring for your cooling system and once in the fall for your heating system. Regular seasonal tune-ups help prevent breakdowns, improve energy efficiency, extend the life of your equipment, and keep your heating and air system running at peak performance.

  • How long does a residential HVAC system typically last?

    Most residential HVAC systems last between 10–15 years, depending on usage, maintenance history, and installation quality. Systems that receive regular professional maintenance tend to last longer and operate more efficiently. If your system is over 12 years old and requires frequent repairs, it may be time to consider HVAC replacement.


  • What are the signs my HVAC system needs repair?

    Common signs you need residential HVAC repair include:


    Uneven heating or cooling


    Weak airflow from vents


    Unusual noises or odors


    Rising energy bills


    System frequently turning on and off


    No heating or cooling at all


    If you notice any of these issues, scheduling prompt service can prevent more expensive damage.

  • Are ductless mini splits better than central HVAC systems?

    Ductless mini split systems are excellent for zoned heating and cooling, home additions, garages, and older homes without ductwork. Traditional central HVAC systems are often ideal for whole-home comfort. The best choice depends on your home’s layout, energy goals, and budget. A professional evaluation can help determine which system is right for you.

  • How can I lower my energy bills with my HVAC system?

    You can reduce energy costs by:


    • Scheduling regular HVAC maintenance
    • Replacing air filters every 1–3 months
    • Installing a programmable or smart thermostat
    • Sealing duct leaks
    • Upgrading to an energy-efficient HVAC system

    Routine maintenance and system efficiency checks are the most effective ways to keep heating and air costs under control.
