Central AC sales and installation

Struggling with summer heat? Get professional installation services from your local trusted HVAC contractor.

The average central AC system installation costs between $2,650 and $15,600. This is a significant investment, so it’s important to hire experienced technicians that take pride in “a job well done.”

Installing central air conditioning is a complicated, time-consuming process that the seasoned professionals at Main StreamMechanical perform with great skill.   We have provided central AC systems and installation to northern Massachusetts and southern New Hampshire customers since 1996 and are committed to delivering the highest standard of quality.

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 15years, provided it is installed and maintained properly. However, performance may begin to suffer after 7 to10years, 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 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.

Only 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.

Commitment to Quality

Massachusetts requires HVAC contractors to be licensed to handle refrigeration and for duct work. Unfortunately, many other companies hire unlicensed technicians that fail to match our standards of quality. Unlike these contractors, Main Stream Mechanical is committed to offering the highest quality service to our customers.

Our technicians are highly trained to live up to our reputation.

Expert Recommendations

There are three different types of central air conditioning systems:

  • Ductless Mini-Split AC systems or ductless AC
  • Heat pumps
  • Whole house central AC systems

Each of these systems serves different purposes, so it can be difficult to choose a system that is safe, reliable and energy efficient. Our Comfort Specialists and technicians can lend their expertise to help you choose the right equipment for your home.
