Why you should book a “Fall Heating System Start-Up” visit:
  • Prevent reactive, costly, “no heat” service calls later in the heating season.
  • Plan and budget for preventative maintenance issues. (If any equipment needs repairs, we’ll provide you with a written estimate.)
  • Enter the heating season with lower risk of heating system malfunction by inspecting, tagging, and starting the heating systems properly.
  • Avoid dangerous leaking fumes due to clogged flue pipes and heat exchanger failures.


Our new online credit card payment feature!! Customers can now pay off an invoice or pay for a service 24/7 via our website's new online payment feature.  And Coming Soon:  a service list option allowing you to prepay for services like installations, fall/winter start-ups, and preventive maintenance!



  • All Phases Mechanical offers annual preventative maintenance (PM) packages
    for homes and businesses. PM, including changing filters, is key to maintaining low energy costs.

  • We can assist you with natural gas and
    Cool Smart rebates & tax credits.

  • You could save up to 30-60% on your gas and electric bills by using a 2-stage gas valve furnace with an ECM motor (variable speed blower) at a 95% gas furnace efficiency rating. That means that for every $1 you spend, 95 cents goes directly into heating your home and only 5 cents is wasted out the flue pipe! (We also have a 98% gas furnace line.)

  • We have over 27 years in custom-designing HVAC systems.

  • The All Phases Mechanical team includes plumbers, electricians, and sheet metal mechanics - over and above our standard HVAC guys.

Here’s a recent 5-star rating from a satisfied customer, Geoffrey Levis:

Whether it’s a hot summer day or a cold New England snowstorm, we at Levis & Sons Gulf maintain a perfect temperature. [They’re] highly recommended to anyone needing a HVAC system installed or fixed.”
