HVAC Emergency: Determining if you have a very severe furnace issue.

By /

[vc_row][vc_column][vc_single_image image=”332″ img_size=”360×170″ label=””][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Furnaces generally operate without incident when properly installed, tested, and maintained by a HVAC professional. But there may come a time you need to know the difference between regular furnace repair service and emergency furnace repair.

If you live in the Cleveland area, you understand the furnace emergency in the dead of winter. Some problems are more threatening than others and require more immediate attention. With a little investigation, you’ll find that some complications are minor to fix, and others require the expertise of a professional.

1. Electrical Issues Seem to be the Problem

Electricity plays a critical role in how your home operates. You rely on your home’s electrical system to provide power when you need it, and that could be powering your heating and cooling systems.

Your lights should not flicker when your system turns on. Electrical issues should be addressed by a professional. Understanding the basics of your electrical system can help you identify and avoid potential hazards, but leave nothing to chance.

This video from the Electrical Safety Foundation International (ESFI) provides a brief introduction to the different components of your home’s electrical system, includes tips for identifying electrical safety hazards, and explains some advanced electrical technologies that can make your home safer.

Do not put yourself or someone else in danger by attempting repairs you are not qualified to do. The Electrical Safety Foundation sites:

Electrical failures or malfunctions were factors in an estimated 43,700 home fires
These fires caused 430 deaths and 1,620 injuries
Causing approximately $1.5 billion in property damage

Having a qualified and trustworthy HVAC professional “on call” can be a life-saver when your furnace equipment calls it quits.

2. Furnace is Making Unusual and Loud Noises

Sometimes a furnace may be running fine, but loudly. If you can tell the noise is a result of the air running through the ductwork, one solution may be to insulate your ductwork to cut down on the noise. If the actual furnace system is making odd noises, this can occur when the pilot light is improperly adjusted or the blower motor lubrication ports need oiling. There may also be an issue with the belts or even the burner.

What are the different noises coming from your furnace?

a. Pinging or popping sounds – could be thermal expansion- the ductwork expanding and contracting as it heats and cools.

b. Rattling noises – loose panels may need to be tightened.

c. Squealing noises – could be a belt that connects the motor to the fan slipped. Or the belt needs replacement.

d. Grinding sounds – probably time to call a furnace repair technician. The motor bearings need repair. (source)

When to call a professional: While it may not seem like an emergency, you should have furnace system noises checked out by a service technician. Early detection of a problem may save you from further damage and a larger repair bill in the future.

3. HVAC System is Turning On and Off Rapidly

In the case of a furnace turning on and off again too quickly (rapid cycling), many causes can exist. The first may be a dirty or worn-out air filter. If you haven’t replaced it within very recent memory, try doing so — it’s a quick and easy fix.

Using old filters puts more stress on the compressor and can lead to mechanical failures over time.

When to call a professional: If a new filter doesn’t solve the problem, you may have a more serious situation. There may be an issue with the blower motor and belts and both require the service of a professional.[/vc_column_text][/vc_column][/vc_row]
