¹The manufacturers, gas company, and GNL all recommend that your systems are checked at least once per year.  With GNL’s Ultimate Savings Agreement (USA) you receive a semi annual check of your furnace in the fall and your A/C in the spring. Your Indoor Air Quality (IAQ) is taken care of during both visits as well. Your indoor comfort system will be safer, run better, save energy, last longer, and keep you more comfortable with GNL’s USA.
