Can ductless systems cool or heat multiple rooms?

One outdoor compressor can connect to multiple indoor heads, each operating independently. Homeowners set different temperatures in different zones. Some systems support up to 8 heads on one outdoor unit, though 2-4 heads is more common.

How much does ductless system installation cost compared to traditional AC?

Ductless systems cost more per ton of capacity than central units but eliminate ductwork expenses. For homes without ducts—especially historic properties—ductless often costs less than adding traditional systems. Licensed technicians provide detailed estimates for each installation.

Do ductless systems work in older Marietta homes?

Yes, ductless systems are ideal for historic homes. Wall-mounted heads avoid damage to original plasterwork and woodwork. Installation requires only small holes for lines and electrical, not the extensive disruption of ductwork addition.

How efficient are ductless systems?

Ductless systems avoid the 10-30% efficiency losses from ductwork leaks and poor installation. They deliver conditioned air directly to rooms. Modern technology and zone control reduce waste. Properly maintained ductless systems operate efficiently year-round.

What maintenance do ductless systems require?

Homeowners clean indoor head filters monthly during heavy-use seasons. Outdoor compressors should be cleared of debris. Professional annual maintenance checks refrigerant charge, electrical connections, and overall operation. Cobb County humidity and pollen require more frequent filter attention.

Ductless Split Systems in Marietta, GA

Always On Time

One Hour Heating & Air Conditioning® of North Atlanta

Ductless split systems provide cooling and heating without running ducts through walls or attics. This technology appeals to Marietta homeowners adding rooms, updating historic homes near Marietta Square, or replacing inefficient window units. The system consists of an outdoor compressor connected to an indoor wall-mounted head delivering conditioned air directly to living spaces.

Why Ductless Systems Work for Marietta Homes

Historic homes around downtown Marietta Square present challenges for traditional cooling—adding ductwork damages original plaster, woodwork, and aesthetics. Ductless heads mount cleanly on walls without invasive installation. Homes in East Cobb with room additions or finished basements benefit from zone cooling—different temperatures in different rooms. West Cobb properties with additions constructed years after the main house lack integrated ductwork; ductless systems solve this without major renovation. The Dobbins Air Reserve Base and defense contractors bring transfer-prone families needing flexibility—ductless systems go where families move.

How Ductless Systems Operate

The outdoor compressor pumps refrigerant through small copper lines to indoor wall-mounted heads. Each head cools or heats its room independently. Multiple heads connect to one outdoor unit, allowing separate temperature control per zone. No ductwork leakage means conditioned air reaches rooms efficiently. Quiet operation—systems produce minimal noise compared to traditional equipment. Installation requires only small holes for refrigerant lines and electrical connections. Units work year-round: cooling during Marietta's hot, humid summers and heating during winter cold snaps when needed.

Installation and Maintenance

Licensed installation includes mounting the outdoor compressor on a sturdy pad or bracket, running small-diameter refrigerant lines to indoor heads, making electrical connections, and charging the system. The process takes less time than traditional ductwork installation. Indoor heads mount on walls at appropriate heights for comfort and appearance. Regular maintenance includes cleaning indoor head filters and occasional outdoor compressor cleaning. Homeowners can perform basic filter cleaning; professional maintenance annually keeps efficiency high. Cobb County's humidity and pollen season mean filters need more frequent attention than in drier climates.

West Cobb's rural character and larger properties support various home ages and configurations.

Dean did a great job helping us out. Between Dean and Daniel out in the field, and Caren and Heather up in the office, this company has helped us feel that not only do we matter as customers, but also that they care about their employees and want to see them thrive. 10/10, highly recommend.

We had an unexpectedly stressful situation where we needed to replace our HVAC system, and One Hour Heating & Cooling was one of several companies we contacted for an estimate. From the very beginning, Rob, the owner, stood out. He was incredibly down-to-earth, honest, and took the time to explain everything to us in detail without making us feel pressured. After meeting with several companies, Rob was by far our favorite, and we felt very comfortable choosing his team for the job. It truly felt like we were becoming part of a family rather than just being another number at a large company, and that made a huge difference to us. The installation team was just as impressive. They were professional, respectful, clean, and truly top-class guys. They did an excellent job and left everything neat and tidy. We’re really looking forward to working with Rob and his team going forward. It’s refreshing to find a company you can genuinely trust, and we’re very happy to recommend One Hour Heating & Cooling to our friends and family! Thank you, Rob and team, for making an unexpected and stressful situation so much easier!

1) When our air conditioner failed after hours, we actually reached a real person who scheduled our repairs for the next day. 2) Greg Nieves was the expert who arrived, and we were immediately impressed with his reliability, knowledge, and efficiency. He knew what he was doing, quickly gained our trust, and guided us to the best option. When one finds integrity and pride in a job well done, it is important to acknowledge that. We didn't know about One-Hour before yesterday, are well satisfied and have now become a regular client.

Zo was fantastic! He came to my home to diagnose an issue with my AC and immediately impressed me with his knowledge, professionalism and decades of experience. He arrived prepared with the right tools, took the time to explain what was happening and helped me understand the different options available. Most importantly, he genuinely cared about finding the right solution for both my needs and my budget rather than simply pushing the most expensive option. I really appreciated his honesty, expertise and willingness to help and I would highly recommend Zo from One Hour Heating & Cooling to anyone in need of HVAC service!

Excellent service and top quality repair technicians. We brought out another company and they insisted we needed to spend over $10,000 for a new A/C system and for $267 One Hour Heating and Cooling repaired our A/C. We are so grateful to work with a trustworthy company. I highly recommend them!
