What SouthCoast customers say
I had a mini split installed in my home in New Bedford, MA by Armus Mechanical, and the experience was fantastic! Edward and his team were professional, efficient, and made sure everything was done perfectly. The system works great, and I'm super happy with how it turned out. If you're looking for a mini split contractor in New Bedford, I highly recommend them!

I had an amazing experience with Armus Mechanical! They showed up on time and did an excellent job at my house. I highly recommend them to everyone. Not only did they assist me with submitting the mass save rebate, but they also went above and beyond to ensure everything was taken care of. I'm extremely grateful for their outstanding service. Armus Mechanical is the best choice for all your HVAC needs!

Got everything all done in about 4 days and now having it, my only regret is not having it done sooner. 10/10. These guys are amazing and if you need any HVAC work done, guaranteed these guys will take care of all your needs and make the process painless. Thank you Eddie and Kevin!

Furnace, Boiler & AC Questions, Answered
Can you come out today if my heat is out?
Yes. No-heat calls go to the front of the line, and repair calls get a same-day visit with a real arrival window instead of a guess.
What rebates and financing are available for a new system?
Mass Save Heat Pump Installer Network participating contractor. Rebates and the 0% HEAT Loan available. We confirm eligibility and file the paperwork. Financing for new systems runs through Wisetack via Housecall Pro, subject to credit approval.
Should I replace my oil boiler with a heat pump?
Often, yes. A cold-climate heat pump lowers heating costs in many SouthCoast homes and qualifies for rebates, but insulation and electrical service matter, so we compare it with keeping or converting the boiler first.
Do you replace oil tanks and install heat-pump water heaters?
Yes to both. We replace weeping or failed 275-gallon tanks, remove tanks during oil-to-gas conversions, and install tank, tankless and heat-pump water heaters, which cut hot-water costs sharply.
Are you licensed and insured?
Yes. Armus Mechanical is licensed and insured in Massachusetts and family owned and operated out of Lakeville. Ask for proof of insurance any time.
