Turning on your heat thermostat to take the chill out of your home is always comforting; except when you don’t get any heat! There are many reasons why this can happen. One important factor is maintenance and cleaning. Just like your car or truck engine; the heating system needs cleaning and maintenance to ensure efficient and safe operation. You may want to review your owner’s manual for more information or the manufacturer’s website of your heating system. Manufacturers recommend an annual cleaning and inspection by a licensed plumbing and heating professional.
