The best thing to see when you are having heating or cooling problems!

All Phases Mechanical has been providing installation and servicing heating and air conditioning to New England residents and businesses for over twenty five years. No job is either too big or too small for our team to tackle. We drive new business by ensuring the loyalty and success of all our customers
- one at a time.

We sell, install and service (7 days a week, 24 hours a day) a variety of top quality, reputable home and business heating solutions, including:

  • Oil furnaces (warm air), oil boilers (steam, water) and hydro air (heat and air conditioning)

  • Gas furnaces*, gas boilers and hydro air

  • *Two -2- stage gas valves and Electronically Commutated Motors (ECM).

  • Water heaters, oil, gas and electric and radiant systems

  • Geothermal with complete engineering package

  • Ductless Split AC and Heat Pumps

1. Air Conditioning Services

On a hot and humid day, there is nothing more refreshing than walking into a cool and dehumidified - air conditioned home or building. Today’s central air conditioning systems are more efficient in cooling, more durable by design, quieter and improve indoor air quality by dehumidifying and filtering the air. A key consideration to a long lasting and efficient air conditioning system is to have the right professional air conditioning company install it right the first time, to back it up with a quality product and qualified service after the sale. Other HVAC companies do not match up to the standards and quality of our air conditioning services. As a best practice, All Phases Mechanical acoustically lines the first few feet of duct and employs flexible connectors to ensure that your new A/C system is as quiet as possible. Our customers have been particularly happy with the new high efficiency units with both Electronically Commutated Motor (ECM) and variable speed blower installed.

2. Free Estimates

3. Heating Services

Oil to natural gas and (LP) conversions are our specialty. With energy and utility costs rising every year, now is the best time to invest in a high efficiency Energy Star rated home heating system. Today’s home heating systems are over 90% efficient compared to 60%-80% just a decade ago. Home comfort control (humidification, filtration) and heating solutions have never been so affordable and efficient. A new heating unit can be a great investment and add value or “equity-in” to any home or office.

4. New Installations

We install new residential and light commercial A/C and heating equipment. Ask us for details regarding current tax credits or rebates from GasNetworks or Nstar on select new installs. Your home is unique. We do not sell “boxes” but rather a custom designed air conditioning and heating system. This is why you will rarely get a price over the phone for a new heating or air conditioning system by All Phases Mechanical. What you WILL get is a fair and prompt estimate, usually in your hand before we leave your home. This gives you the actionable intelligence you need to make the right choice for you and your family.

5. Service

We service and repair all the equipment we sell and install. We welcome new service and install customers. This includes residential and light commercial A/C and heating equipment. We provide preventive maintenance on residential and light commercial A/C and heating equipment including roof top units (RTU’s). Although we are a company driven by our sales and installation business, we also offer maintenance agreements to provide regular inspections of your equipment with minor cleaning, preventative maintenance (PM) and adjustments included to help maintain optimum performance.

8. Certified Oil Burner Technician

In 2007, All Phases replaced the furnace for the townhouse (unit #1) that was my office. It has worked out very well - the heating bills for unit #1 have been running $100 per month less than unit #2.  In January 2011, when the blower motor in unit #2 started to labor, I didn't hesitate to call Carl and have the furnace replaced. They installed it the very next day in a few hours.
Work Completed:  2007 New Gas Furnace / 2011 New Gas Furnace.
