Common Furnace Problems & How to Detect Them

Furnace repair

Faulty heaters are more than a nuisance. They can be dangerous if they pose a fire hazard or, as can happen with gas furnaces, they leak carbon monoxide into your home.

Call us at West Coast Chief if you experience any of the following problems:

  • A furnace that won’t heat to the set temperature.
  • Unusual odors, especially burning smells.
  • Leaking tubes. Shorts in electric heating coils.
  • Vents that fail to expel carbon monoxide.
  • Carbon monoxide sensors that fail to shut down a defective unit.
  • Faulty furnace wiring.

Simple Checks to Improve Furnace Efficiency

Heating bills can add up fast during the winter months, especially if you live in a larger, multi-story home, a poorly insulated older home, or if you prefer a toasty ambient temperature.

Regular maintenance can keep your furnace in peak condition for longer appliance life. A few dollars spent here and there will save you a bundle in the long run.

Yearly Maintenance

We’ll inspect your furnace, lubricate moving parts, replace worn parts, clean it, and tune it.

Replacing Filters

Think of your vacuum cleaner. How well does it run when the filter clogs with dirt, grime, and cat hair?

Exactly. Your furnace is no different, and it takes far more energy to pull and push air through a clogged filter versus a clean filter. Call us for maintenance if you don’t know how to change a filter or don’t know which filter to buy. Replacing filters is part of our maintenance service.

Adding a Humidifier

Moist air has a higher heat index than dry air. It feels warmer. A simple trick to stay comfortable — and you don’t need us for this — is to humidify your home during the winter and dehumidify it during the summer.

Sealing Leaks in Ductwork

A leaky water pipe is a household disaster — everyone springs into action to fix it ASAP. But leaky air ducts often go unnoticed. The problem may persist for years. Air leaks don’t cause the same catastrophic damage as water leaks, but they contribute mightily to high energy bills and general discomfort as heated or cool air fails to reach some corners of the house.

Call us to check your air ducts, seal any leaks, or replace ducts outright if they’ve degraded to the point where we can’t repair them.

Insulating Ductwork

As with sealing leaks, insulating ducts ensures that conditioned air reaches every nook and cranny of your home. It’s a good idea to have us check the insulation on your ductwork every few years.

Checking & Replacing Thermostats

A furnace is only as good as its thermostat. A faulty one can cause heating problems, from failure to heat to uneven heating in different parts of the house.

We’ll check your furnace’s thermostat to see if it needs replacing during our yearly maintenance visit.

Cleaning & Inspecting Gas Connections

We’ll clean and inspect the burners and other gas connections as part of our yearly maintenance service if you have a gas furnace. We’ll also test the pressure to ensure it’s within the proper range.

Checking & Replacing the Blower Belt

The blower belt is a key component in any forced-air heating system, whether natural gas, propane, oil, or electricity.

The blower spins the furnace’s heat exchanger. If the belt slips or breaks, the blower won’t be able to do its job, and your furnace will fail to heat your home.

We’ll check the condition of your blower belt during every annual maintenance visit and replace it if necessary.

Keeping Your Furnace Maintained Saves You Money

A well-maintained furnace doesn’t have to work as hard to heat your home, which means it uses less energy and costs you less money.

Yearly maintenance also helps prevent major repairs. Often, we can catch a small problem during our yearly tune-up and fix it before it turns into a big, expensive problem.

With professional installation and routine maintenance, your furnace will provide you with comfortable, efficient heating for many years to come.

When to Call Us for Repair

As your furnace ages and parts begin to wear out, you’ll run into a problem requiring a repair.

The sooner you contact a professional service like Chief, the less damage your furnace will incur. A minor problem can rapidly become a costly problem if you ignore it.

  1. Learn to recognize warning signs. Take any performance irregularities seriously. No matter how small a problem with your furnace may seem, there’s always the possibility it will develop into something more serious.
  2. A professional heating technician can resolve minor problems before they do severe damage to your heating system.
  3. Unless you turn up the thermostat and leave the furnace running 24-7, you shouldn’t see much fluctuation in your heating bill. If your heating costs spike, there’s probably an underlying issue with your furnace.
  4. Regularly scheduled maintenance is the best way to prolong appliance life, lower your heating bills, guarantee your comfort, and ensure the safe operation of your furnace.

Your Furnace Troubleshooting Guide

Before you call us for furnace repair, you might save yourself time and a little money by taking care of the simple things yourself. If the problem is due to a thermostat setting, tripped breaker, or an extinguished pilot light (in the case of a gas furnace), you may not need us!

  • Your thermostat should be set to “heat.” The temperature setting should be low enough to trip the furnace but high enough to heat your home to a comfortable level.
  • Check circuit breaker or fuse box. If a circuit breaker has tripped or a fuse has blown, reset the circuit or replace the fuse to restore power to the furnace.
  • Check the power switch by your furnace. Sometimes, our technicians go on calls where the only problem is a power switch flipped to “off.” Usually, this switch is on the furnace housing.
  • The furnace motor may need a recharge. You’ll find a reset button near the blower motor’s housing. Press it and hold it down for a few seconds. If nothing happens, wait 30 minutes and try again.
  • If you have a gas furnace, start by checking the pilot light. A draft may have blown it out, or a gas valve may have closed. Reignite the pilot light. If it continues to go out, call us.
