Air Conditioning and Heating

Even with regular maintenance, there comes a time when it's simply not cost-effective to continue to repair an older AC unit. An older AC unit uses much more energy, cools your home unevenly and can promote mold and allergen growth. 406 HVAC performs quality air conditioning installation services in the Billings, MT area.


Consider a new air conditioning installation if:


  • Your current unit is more than 15 years old or has a SEER rating of 10 or less
  • Your older unit uses R-22 coolant which will no longer be manufactured in 2020
  • Your AC unit isn't the right size or power for your home


When we provide you with a quote for a new system, we'll size it properly for maximum cooling efficiency. Our new units are considerably more energy-efficient, using up to 40% less monthly energy than older models.
