Last fall I had everyone who reads my blogs on the regular (thank you for that!) do a mental exercise. Not too tough, like a Sudoku. All you had to do was give your air conditioning system a grade like in school: A to F. That helps you to plan ahead about your comfort system and take measures during the downtime period.
Now I want all of you to do the same for your furnace. Warmer weather means furnaces will soon go into hibernation—although we can never count out cold surprises during April—and attention starts to move to the AC. So it’s time to give your furnace a grade for the season it just handled, and you’ll have an idea if you need to schedule furnace service in Knoxville, TN during the spring.
