A mini-split air conditioner system, also known as a ductless HVAC system or ductless heat pump, is a type of cooling and heating system that provides individual room or zone control without the need for ductwork. It consists of an outdoor unit and one or more indoor units, connected by refrigerant lines.
Here’s how a mini-split system works:
Outdoor Unit: The outdoor unit houses the compressor, condenser, and other components. It extracts heat from the outside air during cooling mode or transfers heat from the outside air to the indoors during heating mode.
Indoor Units: The indoor units, typically mounted on walls or ceilings, deliver conditioned air directly into the room or zone. Each indoor unit has its own controls, allowing for independent temperature settings.
Refrigerant Lines: Refrigerant lines connect the outdoor unit to the indoor units, carrying refrigerant between them. These lines are small and require only a small hole in the wall for installation.
Controls and Remote: Mini-split systems come with user-friendly controls, either mounted on the indoor unit or operated via a remote control. Some systems even offer smartphone apps for remote control and scheduling.
Overall, ductless mini-split air conditioner systems provide efficient and customizable cooling and heating solutions, making them an excellent choice for those seeking individual comfort control and energy efficiency.

Mondragon Mechanical is the most trustworthy and reliable HVAC company I’ve ever worked with. Guillermo and Kimberly are simply the best! This was my first time using them, after finding them through Trane’s official website, and I am beyond impressed with the entire experience from start to finish. My service technician was Guillermo, and let me just say -- don’t let his young age fool you. He is extremely knowledgeable, professional, and friendly. I’ve dealt with other HVAC companies over the years for my Trane system, but I can honestly say Guillermo is one of the best technicians I’ve ever met. He knows his stuff, explains things clearly, and truly cares about making sure the system is running perfectly. Thanks to him, my AC is now working like a charm! A special shoutout also goes to Kimberly in the office, who was equally wonderful. From the moment I called to schedule a service call, she was kind, helpful, and kept me informed every step of the way. I had asked for a 30-minute heads-up before the technician arrived, and Kimberly followed through perfectly with that, giving me Guillermo’s exact ETA this morning. Right on schedule -- something that’s rare these days! What stands out most about Mondragon Mechanical is their honesty and integrity. They truly put the customer first and can absolutely be trusted. That is a rare quality in today’s world, and it’s exactly why I will be calling them for all of my future HVAC needs. I’m already planning to sign up for their seasonal service package for ongoing tune-ups each year. Thank you, Mondragon Mechanical, and an extra thank-you to Guillermo and Kimberly for turning what could have been a stressful AC problem into such a positive experience. I’m a very happy customer and thrilled to have found a company I can finally trust! Lorenzo MunozTrustindex verifies that the original source of the review is Google.

Thank you Kimberly and your team! I will be recommending this company to everyone!! The process was very easy, unlike other companies I have had to deal with in the past! Ana MaldonadoTrustindex verifies that the original source of the review is Google. I purchased a whole new inside and outside unit last year. I’ve recently had issues with it not blowing as cold air as before, i had them come out to check on it and turns out, either they left the coolant low when installing or it has a leak.. mind you think is a whole new unit i paid $8,500. Now they said it’s not their fault and i have to pay an additional $360 to fix? this is ridiculous! Do not purchase here they leave things half done and then try to get more money to get it fixed.

Mini-split systems offer several advantages, such as flexible installation options, individual zone control, energy efficiency, improved indoor air quality, and quiet operation. They are ideal for homes or buildings without existing ductwork and for controlling the temperature in specific areas.
Yes, mini-split systems can both cool and heat. They provide efficient cooling during hot months and can reverse the refrigeration cycle to provide heating during colder months.
The number of indoor units that can be connected to a single outdoor unit depends on the capacity of the system and the manufacturer’s specifications. Typically, one outdoor unit can support multiple indoor units, allowing for zone control and customized comfort.
