Everything You Need to Know

Do You Need a Permit to Install a Mini-Split System?

Yes, most mini-split installations in New England require a permit. Bergeron Mechanical Systems manages the entire permitting process on your behalf, coordinating with local authorities and scheduling inspections. It’s part of what a Diamond Elite Contractor installation includes from start to finish.

How Does the Efficiency of a Mini-Split Compare to Older Systems?

Older systems — including electric resistance heaters, aging oil furnaces, and older propane equipment — typically operate at significantly lower efficiency than modern Mitsubishi Electric mini-split systems. Heat pumps move heat rather than generate it, producing more heating or cooling output per unit of electricity consumed. During a Free Design Consultation, Bergeron Mechanical Systems reviews your current setup to help you understand the efficiency improvement you can expect.

Why Are Mitsubishi Electric Mini-Splits More Efficient Than Older Systems?

Mitsubishi Electric systems transfer heat rather than generate it — requiring far less energy input than conventional fuel-burning or resistance-based systems. Combined with inverter technology that continuously adjusts output to match demand, this makes Mitsubishi Electric systems measurably more efficient across every season.

What is the Total Home Comfort Warranty?

The Total Home Comfort Warranty gives homeowners 12 years of coverage on both parts and labor for every Mitsubishi Electric system installed by Bergeron Mechanical Systems. It’s one of the strongest warranties available in the industry — and it’s only possible because Bergeron Mechanical Systems is a Mitsubishi Electric Diamond Elite Contractor.
