FAQs About Cooling & Air Conditioning - Minneapolis St Paul, MN

How do I save heating & cooling energy cost?

  • Install a Programmable Thermostat
  • During the heating season, set the temperature at 68 degrees when home and 50 degrees when not home.
  • During the cooling season, set the temperature to 78 degrees when not home and to your comfort level when home.
  • Turn off heat/air in unoccupied areas (close the register/vent cover dampers).
  • Enroll in your energy company’s budget plan (a monthly averaging plan that sets a constant monthly rate).
  • Install thermostats on interior walls away from heating or cooling vents and other sources of heat or drafts.
  • Have the heating/cooling system inspected, cleaned and tuned before each heating and cooling season.
  • Seal any drafts in the windows with approved shrink plastic kits.
  • Install an energy star rated furnace and central air. Most older furnaces and central airs are inefficient and do not meet current energy efficiency standards (Minimum 80% AFUE for furnaces and 13 Seer for central airs).
  • Clean the ductwork as recommended by your heating and cooling technician and change your filter regularly. Check your filter monthly no matter what. These can reduce the efficiency of your equipment because you do not have proper air circulation due to restriction in the ductwork and filter.

Common Questions and Answers about Air Conditioners

  • What is the average lifespan of a central air conditioner? - The average lifespan of a central air conditioning system is 10-15 years.
  • What does the term "SEER rating" refer to? - The efficiency of central air conditioners is rated according to their Seasonal Energy Efficiency Ratio (SEER). The SEER rating is the BTU of cooling output during a typical cooling season divided by the total electric energy input in watt-hours during the same period. The higher the SEER rating of a unit, the more energy efficient it is. Many older systems have SEER ratings of 6 or less. The minimum SEER allowed today is 13. Installing a system with a high SEER rating will save you money and reduce your energy usage.
  • Why is bigger not necessarily better? - If your air conditioner is not properly sized to fit your home, your comfort will suffer. A unit that is too large will fail to de-humidify the air. A unit that is too small will not be able to cool your home to the desired level. It is important to find the Goldilocks system for your space: one that is neither too large nor too small, but just right. Our technicians can help you determine your perfect fit.
  • Will my new air conditioner be noisy? - No. Residential Heating and Air Conditioning offers the quietest air conditioners on the market today
  • What happens to my old air conditioner? - The refrigerant in the old system will be reclaimed and the old air conditioner will be removed.
  • Will my new air conditioner control the humidity in my home in the summer? - The only way to control humidity is to have a properly sized air conditioner, the comfort consultant from Residential Heating and Air will make sure the system is sized correctly to control both humidity and temperature.
  • How often do I have to service my air conditioner? - We recommend you have your air conditioner serviced every year to ensure optimal energy efficiency and smooth operation
