Ductless Services

Ductless or mini-split AC systems can be a great option for people who want to regulate the temperature inside their home or business without having to install a central HVAC system. A mini-split AC system has three primary components: an indoor handling unit, an outdoor condensing unit, and a remote control. These units are very efficient because they blow air directly into a room rather than having it distributed via ductwork.

You can count on us at Gill's Heating & Cooling, Inc. to install, repair, or tune up your mini-split AC system. Many people choose ductless for:

Commercial offices
Garages, basements, and attics
Residential bedrooms
Home additions
Older buildings unable to accommodate ductwork

Air Quality Services

You might be surprised by how much stale air and excess humidity get trapped inside your home. Without proper ventilation, this can lead to lingering odors, condensation, and poor air quality that impact your comfort and health. Gill’s Heating & Cooling, Inc. installs HRV and ERV systems designed to continuously refresh your indoor air while maintaining energy efficiency.

Whether your concern is moisture buildup, stuffy air, or energy loss, our ventilation solutions exchange stale indoor air for clean, filtered outdoor air, keeping your home balanced, comfortable, and efficient year-round. We’ll help you choose the right HRV or ERV system based on your home’s size, layout, and existing HVAC setup.
