We are taking the following precautions due to the COVID-19 virus. All of our technicians have masks, glasses, latex gloves and shoe booties if they have to enter your home. Our technicians also have hand sanitizer and disinfectants that they use after every call.
If we are there to do maintenance and we don’t have to come inside your home to get to the equipment, we are asking homeowners to adjust the thermostat for us so we can do the system maintenance without entering the home. We will not be shaking hands and will keep our distance from customers.
A central heating system is a sturdy, hard-working unit, engineered for years of dependable use. Construction methods and materials have been perfected over the decades, and mass production has made build quality very consistent among major manufacturers.
Still, every mechanical device has a limited expected service life. If you decide to stay in your home long enough, you’ll eventually be faced with upgrading your central heating system. Here are some guidelines to help you evaluate when that time is approaching.
Age of the Unit
Gas-fired forced air furnaces have an expected lifespan of between 15 and 20 years. However, expected life is not the same as useful life. By the time a furnace is two decades old, greater energy efficiency and substantially lower operating costs may be available by upgrading to a new unit, even if the existing furnace is still technically functional.
At some point, a central heating system may require repairs so expensive that replacement is a more financially viable option. This is particularly true in the case of a cracked heat exchanger — a critical component for both safety and performance. It’s also the most expensive part in your system. In most cases, if repair costs equal 40 percent of the price of a new unit, replacement is the best course.
If rooms that used to be comfortable during the winter aren’t anymore, or if you’re running your furnace longer and paying higher utility bills to maintain the same level of comfort, simple wear and tear may be taking its toll on your heating system components. Burners and heat exchangers are repeatedly exposed to both high temperatures and rapid cooling, which can stress and degrade components over the years, resulting in diminished heating performance.
