Air Conditioning Services

Expert air conditioning installation and repair services in York, Strafford and Rockingham counties

A new, high-efficiency air conditioning system can go a long way toward lowering your utility bills in summer and add value to your home.

The latest models are far more efficient than systems from even 10 years ago—they can reduce your air conditioning energy use by 20 percent, and up to 50 percent when combined with other energy-saving efforts, such as a programmable thermostat.

Newer systems also use an eco-friendly refrigerant that won’t harm the ozone layer. Plus, an upgrade from clunky, energy-guzzling window units to a whole-house system will not only save money in the long term but also improve the curb appeal of your home.

We specialize in ductless systems—great for hard-to-cool areas, room additions or homes without ductwork. Read more here.
