New Advances in Duct Free Split Systems

Schedule Now

The duct free split air conditioning or heat pump system is quickly becoming the go-to system for conditioning smaller or challenging spaces. A duct free system has inherent advantages in that it has no air or thermal losses from duct work since it delivers the conditioned air directly from an indoor air handler. The recent advances in these systems, also called mini-splits, make them even more efficient than ever.

Inverter Technology

The most significant advance in ductless technology lies in the compressor design. The compressor in any kind of air conditioner or heat pump is the work horse of the system and the one that uses the most energy, much of which when it first starts. Duct free systems that use inverter technology keep the compressor running at different speeds based on the amount of conditioned air the room needs. Instead of turning off abruptly, like most compressors do, it continues to run, although at a much lower speed.

Inverter compressors use less electricity, create less noise, and tend to last longer than their single-speed counterparts, since they’re not subject to frequent starts and stops. Another benefit of inverter technology in duct free split systems is better humidity removal in cooling mode. Since it normally runs at a low speed, more air passes over the evaporator coil that contains the chilled refrigerant, allowing more water vapor to condense and drain away.

Scroll Compressors

Ductless heat pumps equipped with scroll compressors provide much more heating capability, even at temperatures below freezing when there’s less heat in the outside air to harvest. Such a compressor can deliver up to 15 degrees F warmer air than a standard piston compressor. You can find scroll compressors in mini-splits that use variable technology that offer even greater energy savings and comfort, especially when it’s installed to optimize its heating potential for our cold winters.

Air Cleaning

Many mini splits use air filters that trap indoor particulates exceptionally well, providing effective air quality management as well as efficient cooling and heating.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
