Frequently Asked Questions about MRCOOL DIY Mini Split - 54,000 BTU 4 Zone Ceiling Cassette Ductless Air Conditioner and Heat Pump with 35 ft. Install Kit, DIYM448HPC07C140

Most Frequently Asked Questions

Yes, MRCOOL mini splits are known for their quiet operation, with indoor units typically producing sound levels as low as 23–40 decibels, making them suitable for bedrooms and living spaces.

A MRCOOL mini-split typically lasts 10 to 20 years with proper installation and regular maintenance

The cost to install a MRCOOL mini-split system typically ranges from $3,000 to $10,000, depending on the size, number of zones, and installation complexity, with DIY installation potentially saving $500 to $2,000 in labor costs

Other Questions

Mini split installations can be costly because they often require specialized labor, electrical work, refrigerant handling, precise placement of indoor and outdoor units, potential modifications to the building structure, and adherence to local codes and permits, all of which add to the overall time and complexity of the job.

Mini splits are generally cheaper to install than central air systems, especially in homes without existing ductwork, because they avoid the costs of installing or modifying ducts. However, for homes with existing ductwork, central air installation may be more cost-effective. Installation costs vary based on system size, number of zones, and complexity.
