Ductless Mini Split Installations - Top Cooling Systems
Are you considering a ductless mini-split HVAC home system? You may be wondering how it works and why it’s different from traditional HVAC systems. In contrast to a traditional air conditioner, ductless mini-split air conditioners don’t depend on complicated ductwork to circulate conditioned air. Instead, these units rely on a big condenser connected to a series of several air handlers installed in each room through copper wiring.
At least a third of total cooling energy in your home gets lost in the ductwork. By doing away with air ducts, there is a significant increase in efficiency, not to mention the freedom to control individual rooms’ temperatures. When installed correctly, a ductless air conditioner offers more comfort in your home and saves you money.
Our technicians will address any questions and concerns about mini-split systems with many years of experience in this industry. The specialists are well-trained and knowledgeable to provide reliable advice and mini-split HVAC services. Whether you’ve been using a mini-split system for a long time or you’re just thinking of getting one, we are here to help.
Trusted Ductless Air Conditioner Installers Near You
Mini-split systems are significantly different from standard home temperature control units and require a different approach during installations and servicing. Knowing how to identify a qualified mini-split system service provider is vital for maximum efficiency and comfort. Here are the key aspects you should consider:
Specialized knowledge
The ductless units’ unique design and working principle call for specialized training and installation and maintenance experience. That said, not just any HVAC expert can handle these systems well. Make sure to select a contractor with specific skills in ductless AC units.
Exemplary circulation expertise
These units rely on direct air circulation in a room as opposed to using a network of ductwork. Mini-split AC systems require a competent technician with knowledge in circulation principles. Only work with a specialist who can plan and execute the most appropriate airflow plan for maximum efficiency.
Transparent and friendly pricing
While Mini-split is relatively cheaper than traditional HVACs, installation and maintenance costs can accumulate fast. Always settle on a service provider with transparent, affordable cost structures and detailed estimates to make sure you spend within your budget.
Here are five reasons to go ductless

1. Ductless Systems Are Easy to Install.
You can install a mini split practically anywhere in your home. These systems are great for homes looking to retrofit a non-ducted system. They’re also a perfect solution to supplement your central air conditioning system.
Want to add some comfort to your attic, basement, or garage without having to extend your ductwork? Go ductless.

2. Ductless Systems Are Incredibly Efficient.
Most ductless systems have fans that can change their speed based on the temperature inside your home. Variable-speed air handlers start working at full speed, then switch to a slower speed when they reach the desired temperature. They continue running at a slower speed to maintain the temperature, saving energy.

3. Ductless Systems Are Quiet.
These systems are whisper quiet—you will not hear them running. The air no longer travels through creaky old ductwork, creating a rattling sound. Plus, the outdoor unit is much quieter than a conventional air conditioning (AC) unit. You can locate it next to your bedroom window and sleep soundly all night.

4. Ductless Systems Operate in All Climates.
You can install a cold-climate ductless heat pump that gets the job done in temperatures as low as 5 degrees Fahrenheit. No matter what part of the country you live in, a ductless system is perfect for your home.

5. Ductless Systems Allow You to Zone.
Add more than one air handler to your home to create a zone control system. Each indoor unit has a thermostat, allowing you to create multiple temperature zones under the same roof. Why pay for air conditioning in an empty room?

Ductless Mini Split Maintenance
Preventative maintenance plays a critical role in the upkeep of all your HVAC equipment. That especially holds true with ductless mini splits. These systems are incredibly reliable—but like any piece of machinery with moving parts, they require tune-ups and inspections.
You will need to wash the system filters at least once a month—more often if you have pets or anyone who smokes in your home. These reusable filters can clog up quickly, so be sure to clean them regularly.

They took the time to assess my home’s heating needs and helped me select the perfect system for both efficiency and comfort. I appreciated their transparent pricing and no-pressure approach. I was fortunate to have Ryan doing the work and he was knowledgeable, professional & efficient. The installation was seamless. The technicians arrived right on time, and they were incredibly courteous throughout the entire process. They protected my floors and furniture, removed the old furnace, and installed the new system without any issues. They even took the time to walk me through the new unit, explaining how to use it and offering maintenance tips to keep it running efficiently. Since the installation, my home has been warmer, more comfortable, and more energy-efficient. The new furnace heats the house evenly, and I’ve already noticed a decrease in my heating bills.
