Aces Highlands HVAC-Plumbing-Electrical
Aces Highlands installs standby generators, transfer switches and panel upgrades, and repairs furnaces, boilers and heat pumps across Portland and southern Maine.
What they do
The company installs whole-house and essentials-only standby generators, wiring an automatic transfer switch to the electrical panel and making the fuel connection to natural gas or propane. Panel upgrades and generator installs sit alongside its heating work on furnaces, boilers, heat pumps and heating repair in homes and businesses across Greater Portland and Southern Maine. Generac is among the generator makes it installs, and ongoing maintenance is offered to keep backup power ready through the year. Emergency service is available, and the business is open around the clock, every day. Financing is available for larger projects, and free estimates are provided for most installation work. Brands it works with include Carrier, Daikin, Mitsubishi and Viessmann.
