Furnace Care

As summer turns to fall, inevitably the day comes where it’s time to switch your thermostat from ‘cool’ to ‘heat,’ and bring your furnace to life. But how well your furnace performs depends on how well it’s maintained, because even a new furnace loses efficiency after just one year.

The combustion chamber is a common source of lost efficiency.

Lost efficiency begins in the combustion chamber. Soot buildup can corrode chamber walls; cleaning it out boosts performance. Before replacing the cover, it’s important to inspect for holes and corrosion.

Damage to the heat exchanger can affect performance and safety.

The heat exchanger should be carefully inspected by a professional, because a cracked exchanger can potentially increase carbon monoxide levels, which can pose a danger to a home’s occupants. That’s why testing combustion ensures not just performance, but safety as well. Gases are measured in the exhaust flue, checking for proper fuel and air balance.

Burners and ignitors should be checked carefully.

The burner may need adjustment. The burner flame’s color and shape at the ignitor are the best indication of complete and stable combustion.

In gas furnaces, ignitor tubes are typically vacuumed clean as part of an annual checkup. Your system’s exhaust flue pipe also needs careful inspection for holes that could allow carbon monoxide leaks. While smaller holes can be patched, a corroded flue pipe should be replaced.

Finally, there are some steps homeowners can take to help their systems breathe easier.

Check and replace air filters regularly. Be sure to use the right size. Pleated ones work best. You should also annually remove and clean registers, and vacuum floor ducts. Lost efficiency means increased energy bills. That’s why annual maintenance helps keep your home warm and your system efficient.

Time for a Furnace Tune-Up

While we’ve been seeing some sunny days recently, Sacramento is definitely not out of the woods yet when it comes to cold weather. With our recent wet weather, chances are that you’ll have reason to be running your heater occasionally through at least April, if not later.

This is why we recommend having one of Gilmore’s expert technicians come out and perform a furnace tune-up, if you haven’t already. Furnaces, like cars, need the occasional inspection and tune-up for peak performance. Without maintenance, furnaces can develop problems resulting in costly energy bills, substandard performance, and even health risks for you and your family (carbon monoxide leaks are no joke!).

Here’s what you can expect from our furnace tune-up service calls:

  • Thermostat calibration
  • Wiring inspection
  • Visual heat exchanger inspection
  • Burner check
  • Removing all covers for full equipment inspection
  • Blower motor check
  • Gas leak check for units that use natural gas
  • Ensuring unimpeded air flow and venting
  • Checking for acceptable manifold pressure
  • Air filter inspection

Furnace tune-ups offer a variety of benefits.

In addition to peace of mind, having your furnace serviced provides a number of great benefits, included enhanced performance, lower energy bills, reduced repair costs, a longer lifespan for furnace components, and avoiding safety hazards such as carbon monoxide and natural gas leaks.
