 A penny for your thoughts, presented by Lincoln Heating and Air. For air conditioning assistance, visit our website, lincolnheating.com. I'm Robert Quirk, owner of Lincoln Heating and Air, and my pledge to you is to make every penny count. If your air conditioning system is more than 10 years old, waiting until next year to replace it will cost you thousands more. On January 1, new refrigerants on air conditioners take effect, and you guessed it, it will cost you much, much more money.
