SOUTH BRUNSWICK, NJ—In an exclusive interview with www.NJnewjersey, we asked GUARANTEED SERVICE'S President, Adam Belitz if he thought an annual furnace or boiler tune-up was necessary before the cold weather arrives.  Adam responded “100% yes, regular maintenance leads to fewer repairs and can prolong the lifespan of your furnace or boiler.  The reverse is also true. Neglecting proper heating system maintenance can reduce its lifespan”

The Fall and Winter seasons are quickly approaching, and it’s time to be proactive with your homes heating tune up.

Adam Belitz, mentioned “At this point, it’s probably been 7 months since you last ran your heating system for any length of time. Can you expect your heater to run at peak efficiency once you need it again every day?  To put this in perspective, let’s imagine that you’re about to drive your car cross-country. Your car has been sitting in the garage for 7 months, except for the occasional spin around the block. Before starting the long drive, wouldn’t you bring your car in for a tune up, an oil change, or even a tire rotation? You’d want to know that your car is running in top condition.  You can think about your furnace or boiler maintenance much the same way. NJ’s winter season of cold weather means a long period of heavy use for your heater. Give your heating system a head start by making sure it’s ready.  Or, you’ll run the risk of having lower operating efficiency or even a break down that would have been preventable.”

GUARANTEED SERVICE is reminding us all of the importance of a furnace or boiler tune up for both efficiency and safety.
