High-Efficiency heat pumps

High-Efficiency Heat Pumps are best described as an air conditioner that can also run in reverse to generate heat, and are a great energy-efficient alternative to traditional furnaces and air conditioners. Mini-Split systems are a very popular style of heat pump that allow individual zone control for more efficient heating and cooling. Since there are no ducts, systems lose less than 5% cooling versus 40% for traditional forced-air systems. 

Ductless Mini-Split Systems

• Offers Heating and Cooling in one system
• Control each room's temperature independently
• Wall mounted and no ductwork required
• Quiet, energy-efficient and affordable

Heat Pump Water Heaters are an excellent way to efficiently heat water for domestic use or radiant heating, and use significantly less energy than a traditional water heater.

Energy Efficiency conversion

Converting to an Energy Efficient heating, cooling, or ventilation system can result in lower operational costs for building managers. Many new systems are also more compact, delivering a better performance while taking up less space. If your building's HVAC systems are failing or are too expensive to maintain, Gem Mechanical is ready to provide turnkey Energy Efficiency solutions.
