Quality Assurance:
These contractors are recognized for superior installation quality and adherence to strict standards, which ensures higher system performance.
Reputation & Status:
Being a Diamond Contractor indicates a high level of trust, and in some cases, “Preferred” status requires high-volume, authorized, and verified installations, demonstrating continued expertise.
Ductless Overview
Ductless cooling and heating systems are reversible, two-way heat pumps that simply take heat energy from one place and move it to another by compressing and expanding refrigerant.
- Outdoor unit: connects to the indoor unit by a small bundle of cables, including a refrigerant line. The unit is placed outside of the home on ground level.
- Indoor unit: mounted on a centrally located wall. One ductless system is enough to heat and cool an average-sized home.
- Remote control: allows occupants to adjust the settings for maximum efficiency, comfort and control.

Mitsubishi Electric is America’s #1 selling brand of ductless cooling & heating products
In contrast to massive, conventional heating and cooling systems, ductless are more compact and straightforward, not to mention aesthetically appealing and cost-effective.
Mitsubishi Electric single-zone systems consist of an outdoor and indoor unit. The outdoor unit can handle up to 8 single units at a time and comes in a variety of styles.
Energy Efficiency – Ductless vs Ductwork
A Mitsubishi Electric ductless system continuously regulates itself by maintaining a steady, comfortable indoor climate. The temperature you set is the temperature you get!
| Conventional Ductwork | Mitsubishi Electric Ductless |
| Hinders overall heating and cooling efficiency by around 25% | Saves up to 40% on heating & cooling bills |
| Distributes air through a network of leak prone ducts | Distributes air directly from indoor unit into the conditioned space |
| Heats or cools entire home or not at all | Full control over temperature of any single room being occupied |
SINGLE-ZONE
One indoor unit connected to an outdoor unit provides individual comfort control to a single defined space in your home.
MULTI-ZONE
Individually control up to eight zones in your home from one outdoor unit for ideal personalized comfort.
