For nearly 30 years, N.E.T.R. Inc. Heating and Cooling Systems has made homes and businesses more comfortable. We provide top quality heating services in Boston and the surrounding area. Whether you need a new furnace or a tune-up on your existing heating equipment, we can help. We provide services for a range of units including furnaces, heat pumps, and boilers. We also work with a variety of brands, including Mitsubishi. 




Heating Installation

We work with both new and existing construction for residential and commercial clients. Not sure if you need a new heating system? We can help you crunch the numbers to compare the cost of repairs and your current heating expenses to the price of a new system. Then, if you decide it's time for a new heating system, we will help you find the perfect heating system for your space, and of course, we take care of the installation.

Mini-Split Heating Units Installation

Although we work with a wide range of units, we are an authorized Mitsubishi dealer, and we focus on mini-split systems from Mitsubishi. These ductless heating units pump refrigerant through tiny tubes from an outside unit to an indoor air handling unit. The indoor units are small, versatile, and discreet, and they can all be controlled separately, allowing you to embrace zone heating. 

For residential use, we often recommend the Mitsubishi Hyper-Heating INVERTER. This high-efficiency heat pump provides year-round comfort at significantly less than the cost of most heating systems. The Mr. Slim is ideal for small commercial spaces, office buildings, and server rooms, while the CITY MULTI provides everything you need for a multi-unit apartment or commercial building. 

Heating Repairs

At N.E.T.R. Inc. Heating and Cooling Systems, we provide heating repairs to commercial and residential clients. If your heater isn't working correctly, our certified technicians can assess the issue and do repairs as needed. Signs you may need a heating repair include the following:

  • Heater isn't turning on
  • Heater cycling on and off repeatedly
  • Not responsive to your thermostat
  • Unusually high utility bills
  • Cool air blowing from your vents or air handling unit
  • Burning odors
  • Strange noises
  • Uneven heating

Rather than waiting for something to go wrong, you should have a technician look at your heating system on a regular basis.

  • Lubricate moving parts
  • Replace or clean filters
