Ductless and Mini-Split Installation Services in CT and NY
Trust Degree Heating & Cooling to install & service ductless Mitsubishi cooling. Mitsubishi electric ductless cooling systems offer energy efficiency & increased comfort.
At Degree, we’ve seen ductless mini-split systems rapidly gaining popularity in the Connecticut and New York area, and for good reason. Their efficiency, versatility, and often lower cost compared to traditional ducted systems make them an ideal choice in many situations. These systems are particularly well-suited for add-on rooms, outbuildings, or any space lacking existing ductwork. Additionally, they excel in addressing temperature control challenges in specific rooms that experience excessive heat gain from sunlight or struggle to maintain warmth during winter. Even entire homes can be cooled and heated effectively with a system of ductless mini-split systems. There’s so much these units can do, especially in our area's swings in temperatures.




More Control and More Comfort
If any of these heating and cooling scenarios apply to your situation, don't hesitate to reach out to us for a consultation regarding a ductless installation. We'll inspect your home or outbuilding's layout and structure to offer an optimal heating and cooling solution. Additionally, we'll assess your electrical infrastructure to help us plan the best location for the indoor and outdoor units. We’re familiar with the specific challenges and opportunities that come with installations in the Connecticut and New York area, including local building codes and weather considerations, and provide you with expert guidance.
Degree’s Technicians Arrive for Installation
Upon arrival for the installation of your new ductless mini-split system, our technicians will already have a detailed plan. They will arrive with the new equipment and all the necessary tools to install the units efficiently. Our installation plan will include the best placement of both the indoor and outdoor units, taking into account factors like sun exposure, proximity to electrical sources, and aesthetic considerations, along with any required brackets or attachments for installation. Typically, our ductless system installations can be completed within a day or a day and a half, depending on the project's scope.
We Prioritize Safety and Aesthetics During the Ductless Installation Process
In contrast to a ducted central air conditioning system, installing a ductless mini-split system is often relatively straightforward. We'll connect the indoor and outdoor units using refrigerant and electrical lines that are tightly sealed and protect them with a line set cover. Our priority is ensuring a clean, professional appearance that also protects your lines from damaging elements, including snow and ice in our region. We ensure there are no leaks, that refrigerant is at optimal levels, and that there is proper drainage of any condensation to the outdoors. Electrical power will be set up according to specifications we found during our initial inspection. We will connect it all to your power panel safely and in compliance with local electrical codes. Every ductless mini-split installation we do is a little different, but we have years of experience in dealing with the quirks of home heating and cooling in the Connecticut and New York area, so rest assured that we’ll get it done right.
The Final Checklist: Inspection, Testing, and Commissioning
Once the work of the unit installation is done and your new system is powered up, we begin testing. We won’t leave until we know your new ductless mini-split system is working to our high standards. We run a diagnostic to check the pressures, charges, connections, and performance of the indoor and outdoor units. When we hand you the remote control, we will be confident that your new system will be cooling and heating the area to your satisfaction throughout the varied seasons of the year, from hot summers to cold winters.
