This proposal outlines the installation of a 3-zone Mitsubishi Hyper Heat ductless system for your home. Because this system will be a primary heat source for the bedrooms, I am utilizing the advanced FX Series indoor heads. These specific units are engineered to deliver their true, rated heating BTUs even in the bitter cold, ensuring your family stays perfectly warm all winter long. Scope of Work 1. Outdoor Equipment & Site Prep Condenser Installation: Supply and install one (1) multi-zone Mitsubishi Hyper Heat outdoor condenser on the back side of the home. Site Preparation: As we discussed during my visit, you will be removing the existing section of fence prior to our arrival so we have the necessary clearance to position the unit in its optimal location. Winterization: Because this is a Hyper Heat system, we will mount the unit on a heavy-duty snow stand and install a protective weather baffle ("ice hat") to protect the fan motor and coils from winter snow and ice accumulatio

I needed to have shut off valves under my kitchen sink and a new hose attachment on my sprayer since the cheap plastic tubing was cracked. Mark was punctual, professional and extremely knowledgeable regarding the job. I am always impressed with GSM and how they run their family business. Mark completed the job quickly and efficiently. I can trust GSM and will continue to seek their help in the help in the future. GSM has installed a mini split, oil boiler, hot water heater in my home and I would highly recommend them to family and friends.
