Serving local Metro East communities with same-day expert plumbing, heating, cooling & electrical services.
Ductless mini-split systems provide efficient heating and cooling for many Caseyville homes. When yours isn't performing—poor cooling, odd noises, or error codes—Morrison Plumbing, Heating, Air & Electrical can diagnose and repair it quickly.
We service all major mini-split brands. Our technicians are trained on indoor units, outdoor condensers, refrigerant, and controls. Same-day service is often available for urgent problems.
Mini-splits run heavily in summer for cooling and in winter for heat. Hot, humid summers and cold snaps in Southern Illinois increase wear and can expose refrigerant leaks, sensor issues, or dirty coils. Regular maintenance and prompt repair help your system last and perform well.
Many mini-split issues are repairable. If the system is very old, has had multiple major repairs, or parts are no longer available, replacement may be the better option. We’ll give you an honest recommendation.
