What Clients Say about us..
What We Do With Mini Splits
All Systems designs and installs ductless mini split systems throughout Haviland and Dutchess County, sizing each zone correctly so systems run efficiently in our cold winters and humid summers. Installation includes outdoor unit placement with proper clearance for airflow and condensate drainage, refrigerant line routing through walls or along exteriors, electrical service, condensate drain installation, and precise refrigerant charging. / We install Bosch and Mitsubishi mini splits—both perform reliably in Dutchess County's sub-zero winter peaks. Repair work addresses refrigerant leaks, compressor failures, frozen coils from airflow blockages, and drainage clogs. Annual maintenance in Haviland homes includes filter cleaning, coil inspection, and refrigerant verification before the heating season starts.

Mini-Split Installation
Mini-split installation in Haviland involves sizing the right system for your home, running refrigerant lines through walls, and integrating an outdoor condenser unit with indoor wall-mounted or concealed heads. All Systems performs Manual J load calculations to match equipment capacity to your square footage and insulation, ensuring efficient heating and cooling throughout Dutchess County. The system is then commissioned with refrigerant charging and pressure testing to manufacturer specification, leaving you with a fully operational ductless unit.

Bosch Mini-Split Installation
Bosch mini-split installation in Haviland includes sizing your home with a Manual J load calculation, running refrigerant lines and electrical hookup, and commissioning the system to manufacturer specifications. All Systems is a Bosch Gold Pro dealer, meaning every installation comes with a 10-year parts and labor warranty instead of the standard 5-year. We handle single-zone and multi-zone configurations for any room in your Dutchess County home.

Bosch Mini-Split Repair
Bosch mini-split systems fail for specific reasons: refrigerant leaks, compressor malfunctions, electrical control failures, and frozen evaporator coils. All Systems Heating and Cooling diagnoses the exact problem using specialized tools and factory-trained methods in Haviland, then repairs or replaces the failed component to restore full heating and cooling capacity. We test every repaired system against Bosch's specifications before returning it to service.
