Summer may be over, but in Hawaii, the heat is here year-round. Fortunately, there have been tremendous technological advances in the HVAC industry, especially with proven innovators like Mitsubishi Electric.

Now is a great time to install new air conditioning or upgrade an outdated system. The pros at Alternate Energy Inc. (AEI) offer these tips for getting the very best system and installation:

Invest in the best product you can afford


A good AC system should last you for a decade or more. You want one that is cutting-edge efficient, technologically advanced, aesthetically pleasing and problem-free. That’s why AEI sells Mitsubishi Electric HVAC systems exclusively. Mitsubishi is consistently recognized by contractors as the No. 1 preferred brand with the highest quality rating. Plus, Mitsubishi’s patented INVERTER technology and high SEER efficiency rating mean substantial energy savings.

Choose a contractor with staying power

How long have they been operating in the state? Will they be around to service your system in the future? A long-time kamaaina family business, AEI has over 20 years of contracting experience in Hawaii and thousands of satisfied customers. They hold the prestigious Mitsubishi Electric Diamond Contractor status.

Also, ask how competent are the installers? AEI’s licensed HVAC installers (C-52) and electricians (C-13) are proud employees, not subcontractors. They expertly handle any electrical needs that may arise pre- or post-installation. AEI’s design engineers design the best-fit solution for your AC installation, while an administrative department handles all City & County building permits and HOA requirements.

Check out the warranties


This is your insurance against any future problems. AEI offers an attractive two-year Workmanship Warranty, and Mitsubishi backs that with a seven-year parts/seven-year compressor manufacturer’s warranty.

Get the full picture

When you invest in home cooling, it’s wise to review your entire energy profile. Is solar water heating, PV or electric vehicle charging in your future? AEI will see the bigger picture, to fully optimize your overall energy-efficiency.

Can the contractor help you pay for it?

AEI has an exclusive partnership with Central Pacific Bank, to help you pay for your new AC. AEI’s Just Cool It Now Sale offers a PV + AC bundle, saving you up to $1,500 off a new AC system with the purchase of a PV system; and an AC Only Special, with a savings of up to $250 off per room (some restrictions apply) — while supplies last!
