In St. Paul, residents do everything possible to keep the warm air inside their homes in the winter for optimal comfort and economical heating bills.

  • Adding Air Purification – Investing in whole-home air purification or a room air filter will help remove the contamination in your home during the winter months.
  • Air Exchanges – Introducing fresh outdoor air into your home is the best way to eliminate the polluted air locked inside your house. So when the sun is shining and the daytime temps warm up, take a few minutes to open doors and windows to let in some fresh air.
  • Air Exchangers – An air exchange can be installed in your HVAC system by the team at Blue Ox to ensure that the air inside your home is always fresh. The unit will remove the low-quality contaminated air from your home while introducing fresh air into the HVAC system to increase your home’s air quality and reduce breathing issues due to allergies and asthma.

The Capital of Minnesota, St. Paul was known first as Pigs Eye because of the tavern built on the location. This building was the first for the future town, and it was constructed in 1838. The name was changed for the St. Paul chapel that was constructed just a few years later. Located on the river, the city soon became a main stop for steamboats as well as railroads. In the early 1900s, St. Paul became a safe haven for criminals with the agreement that they could stay as long as they didn’t commit any crimes in the city. Some famous names during that era included Ma Barker, Baby Face Nelson and Al Capone. Today, St. Paul has become a major metropolis with plenty to see and do in the area.
