Warning Signs of Problems by the Best HVAC Company

It is important to note that there are general signals of furnace malfunction before going into the diagnostic steps. Keep an eye out for:

Inconsistent Heating

If there is one problem that is common with many furnaces and which has been experienced before, then it should be evident that something else must be wrong somewhere.

Unusual Noises

This problem manifests itself in rattles, knocks, and squeaks coming out from the furnace.

Frequent Cycling

Another warning sign explained by North Georgia Heating Company is short cycling. This issue is indicated by a furnace switching on and off too frequently.

Strange Odors

Any odd or nasty-smelling odor that resembles a burn or gas should be looked into immediately.

Spike in Utility Bills

Your furnace may need to be fixed by heating repair technicians in Blairsville, GA, if there is an abrupt and no apparent reason for a hike in energy bills.

Steps to Diagnose Furnace Problems

Since our experts at Wayne's Heating & AC have already found the symptoms of malfunctions in the furnace, let us explore a systematic method to identifying common furnace problems. They will guide you in identifying the precise origin or cause of the problem and thus give you a chance to address it directly.

Step 1: Check the Thermostat Settings

First, check if the thermostat is facing the ‘heat’ position and set at higher than the current room temperature. Often, this is as easy a resolution of small issues.

Step 2: Inspect the Air Filter

An obstructed or filthy air filter may inhibit airflow, resulting in a heated furnace. If a visible filter appears dirty, replace it.

Step 3: Examine the Pilot Light

The heating and air conditioning repair contractor explains to check if older pilot-light furnaces still have flames burned by them. In case not, relight them as per manufacturer’s guidelines.

Step 4: Inspect the Circuit Breaker

The furnace may shut down because of a trip of the circuit breaker. Open the breaker box and verify that the switch is on.

Step 5: Examine the Ventilation System

If your furnace is overheating, then this is because of blocked or obstructed vents, which hinder airflow. Check that all grills and ventilators are not obstructed.

Step 6: Monitor for Short Cycling

Observe the furnace as it operates. If it's turning on and off too frequently, it may be a sign of a malfunctioning component.

Step 7: Listen for Unusual Noises

Turn on the furnace and listen for anything weird. These noises could suggest mechanical problems mentioned in the points above.

Being able to detect furnace problems is an important skill of furnace repair service companies. This will help to save time and money and lower discomfort from the house. Using this manual as a guide, some minor problems in furnaces can be addressed by observing signs of failure. However, in case the problem persists, consider opting for professional HVAC services.

Frequently Asked Questions

Why is My Furnace Blowing Cold Air?

There may be several reasons here, ranging from a bad thermostat, a dirty air filter, and a faulty blower motor. One should check these components out or hire a gas furnace service.

What do I do when I smell gas near my furnace?

In case you smell gas, shut down the furnace, ventilate through open windows, and vacate the place. Call in a professional technician and your gas company right away.

How often should I change the filters in my furnace?

The type of filter and the manufacturer's recommendations are just two of the variables that affect how frequently filters need to be changed. The filter should typically be checked and changed every one to three months.
