For air conditioning installation and energy-efficient air conditioners that can save you money while helping you beat the summer heat, Main Stream Mechanical has the units you need to stay cool, and the installation expertise required to make sure you get the most out of your AC system.

Home air conditioning systems have come a long way in recent years. No matter the size of your home, new and state-of-the-art technologies ensure there is an AC system just right for you, whether you're seeking to cool only one room or an entire, multi-level residence.

Main Stream Mechanical's air conditioning technicians are highly skilled in the installation of several different types of units, including:

  • Central AC – Installing a central AC system is ideal for larger homes and residences with many rooms, as cool air is easily and quietly delivered directly from the source to each room in the house.

  • Ductless AC Units – Don't have an air duct system for central AC? No problem! A ductless air conditioning system provides many of the same benefits as central AC but without ductwork. These types of cooling systems are quiet, compact, and simple to operate.

  • Hi-Velocity AC systems – Unico systems offer high performance and superior comfort in homes where conventional cooling systems can't.  The flexible small ducts can be routed through existing ceilings, floors, and wall cavities without compromising the design or architectural integrity of your home.

Why you should trust Main Stream Mechanical with your central AC installation:

There are many reasons New England consumers trust Main Stream Mechanical for their AC installation needs.

Why consider an energy-efficient AC system?

The benefits of energy-efficient air conditioning systems are many. Energy Star AC units are required to pass stringent testing to provide the highest levels of performance with the lowest environmental footprint. Increased performance means that energy-efficient AC units not only lower the cost of your cooling bills but also last longer than standard systems. In some cases, the installation of an energy-efficient cooling system can even earn you certain incentives, rebates, or tax credits.

Do you need to install a new AC system?

If you’re tired of suffering through the heat of summer without AC, or just tired of lugging those window AC units in and out of the attic year after year, then perhaps a central AC unit from Main Stream Mechanical is exactly what you need to "beat the heat."

It’s not just those without central AC that may be in need, you may need to replace a currently installed unit if it is starting to fail. Your AC system should last 10 to 15 years, provided it is installed and maintained properly. However, performance may begin to suffer after 7 to 10 years, so it may be prudent to install a new central AC unit.

You should consider installing a new central AC system if you experience the following:

  • Your AC shuts off unexpectedly.

  • Your energy bills are rising unexpectedly during the summer months due to poor efficiency.

  • Your AC fails to cool your home properly.

  • Your HVAC technicians identify a number of different problems during the troubleshooting process.

As your trusted HVAC contractor we will diagnose problems with your system and help you decide if installing a new system is necessary.
