Here we are, only half-way through June and things are really heating up this summer. According to information from the National Oceanic and Atmospheric Administration, this past May tied for the warmest May on record. Fossil fuel emissions and carbon dioxide are the likely culprits behind this upward trend. If your current air conditioner is struggling to keep up, consider upgrading to a new high-efficiency AC unit or geothermal heat pump. You’ll stay cool and save money while you help save the planet.
