Ductless Mini Splits
Ductless Mini Splits


Ductless mini-splits are compact heating and cooling systems designed to control the temperature in specific rooms or living spaces within your home or office.

Why a Mini Split?
Mini-splits can be an ideal solution for heating and cooling areas where adding traditional ductwork is not feasible. This makes them especially useful in older homes, room additions, garages, basements, or small office spaces.
The primary advantages of ductless mini-splits include their small size, energy efficiency, and zoning flexibility. Many models allow up to four indoor air-handling units — each controlling a different room or zone — to be connected to a single outdoor unit. This targeted comfort solution can help lower energy costs and improve efficiency. As your local HVAC experts, our team is here to provide you with the options required to live comfortably.

What our customers are saying
Crew Was Outstanding
"Brian just installed a new air conditioner and furnace. The crew was outstanding, the work was excellent and the price was fair. I have to say that Carroll Mechanical is the best company I have ever dealt with. If you want the best quality work, call Carroll Mechanical. I would recommend this company to everyone! If all companies that I have called were this good, I would be so happy! Thank you Brian and crew!"

Cheaper Quote Than The Competition
"Our very old water heater went out unexpectedly. I called Carroll Mechanical Services as well as another local company. Carroll's quote was $700 cheaper than the other guys, and that included coming out after hours on a Friday to perform the replacement. The installers were friendly, fast, and made no mess. Would definitely hire again."
Could Have Taken Advantage, But Didn't
"First time I called, they gave me advice over the phone for a few simple things to check with my malfunctioning furnace. I got my heat going, and I made a mental note to remember them in the future. Next season I had more problems they fixed a blown fuse for a very reasonable price. Eventually I opted for a total furnace replacement. The install was tidy, the employees were guys you don't mind in your house, and Brien was very organized with rebate, warranty and permit paperwork. Satisfied customer, will be the first place I call in the future."
