Our home heating services

We offer repair, installation and maintenance services for:

If you’re looking to install an inefficient furnace, then you can choose just about anyone to do the work. However, if you’re looking for a high-efficiency forced hot air furnace installation, you want someone who specializes in this work. The newer energy efficient models work differently now than they did 20 years ago. This is where Green Energy Mechanical separates itself from the pack.

We provide repair, installation and maintenance services for a variety of heating systems. Our technicians and project managers are constantly getting trained on the newest and best technical methods for installation and service of HVAC systems. That means that you will get exactly what you pay for and nothing less. It also means that your system will be installed correctly the first time, saving you money on unwanted future repairs.

For an inspection of your HVAC and heating system and a free estimate for furnace replacement, give us a call or contact us online today! We service Randolph, Weymouth, Brockton and nearby areas of Massachusetts.

Energy Efficient Furnace

Most older furnaces have efficiencies of 56% to 70%, but newer models can achieve efficiencies as high as 98.5%, according to the US Dept. of Energy.

Is it time to replace your heating system?

If you can answer "yes" to any of these questions, it might be a good time to think about having your heating equipment replaced by an expert HVAC contractor.

  • Is your furnace more than 15 years old?
  • Are some rooms in your house colder than others?
  • Does the air in your home feel too dry or humid?
  • Is your furnace noisy?
  • Does your heating system require frequent repairs?
  • Are your energy bills high?

An old, inefficient furnace or heater costs more than you realize

For decades, electricity, gas and heating oil costs were low enough that we didn't need to worry about our monthly utility bills. But today's growing energy demand has caused electricity and fuel prices to shoot up -- and it will only get worse.

The older your furnace equipment is, the lower its efficiency. Today's heater and furnace equipment is a lot better at converting fuel or electricity into home heat.
