Mini-Split Heat Pump Installation & Replacement

The benefits of mini-split heat pumps

Wicked Efficient

Our mini-split systems provide “wicked” efficient cooling AND heating. Heating & cooling accounts for 49% of your utility bill. Our systems are so efficient, they save 24% on your utility bill… seriously!

Year-Round Energy

Our mini-split systems are heat pumps, meaning they can cool AND heat your home. Our standard models can provide you with supplemental heat. This means you still rely on your traditional heating system but take advantage of the heat pump in the fall and spring (saving you money on your oil/gas bill).

Our Low-Temp models provide full heating capabilities down to -15 degrees outside temperature. This means, that if your home is the right application, you can use our mini-split heat pumps as your home’s sole heating system. Our own Director of Operations at GSMS has this model installed in his home and has clean and warm heat all winter long without relying on any form of backup heat.

Green & Clean

Mini-split heat pumps do not create heat (nor cool). They simply transfer the heat already in the air from one spot to another. This is the reason why they are so efficient. What’s my point? They use electricity to transfer this heat and electricity only. If you’re interested in a net-zero home or are concerned about your energy usage impact, you could look into adding solar. With solar installed on your home, you could power your mini-split heat pump with solar power!

​Choose a professional for your solar installation and choose a heat-pump specialist for your mini-split system! As a mechanical contractor, we’ve been installing heat pumps for well over 30 years and are truly mini-split professionals.

Zoning for EVERY Room

This is the beautiful feature of mini-split systems. Each indoor unit is controlled on its own with its own thermostat. What’s the big deal? Now instead of setting one temperature for your entire house, you can control each room! Think about turning on the light switch in only the room you use. That makes sense. What doesn’t make sense is if you had one light switch to turn on every single light in your house. This is the equivalent of having one thermostat in your house.

​You also guessed it… zoning leads to even more energy savings too!
