Common Furnace Problems and How to Fix Them

Good Deals Heating and Cooling Furnace heatingWhen your furnace is having problems in the middle of winter, it is an anxiety-elevating problem. Whether it’s a residential or commercial setting, a working heating system is a must. There are different issues that people encounter when it comes to furnace heating. This article will focus on some common problems and how to fix them.

No Heat

Feeling heat coming from the air ducts is one way to know if the furnace is working. If there is no heat, double check the thermostat is set to heat and that the temperature is at a comfortable level. Next check to see if the circuit breaker for the furnace was tripped, if so, reset.

Not Warm Enough

Once again, check the thermostat to see the temperature setting. Check the air filters and if they are dirty, replace them. A dirty filter will make the furnace much less efficient.

Limit Switch

The limit switch turns on the blowers that circulate the air throughout the house. There is a sensor on the limit switch to turn on once the air is warm. Otherwise the blower circulates cold air. A malfunctioning limit switch shortens the lifespan of your furnace blower. To fix it, have a technician replace the limit switch.
faulty pilot control or an electric ignition

A gas furnace heating system can either have an electronic ignition or a pilot control for a constant flame. Clogs or drafts can cause these systems to malfunction. Inspect your furnace after turning it off and follow the direction to reset the pilot or consider calling a technician.

Noisy Furnace

A rattling, rumbling and squawking furnace needs immediate attention. The noise may indicate airflow reduction, mechanical problem or a clogged burner. Several solutions may help reduce noise: insulating the ductwork and cut down the sound, adjust the pilot light or lubricate the blower motor.

Malfunctioning Thermostat

A malfunctioning thermostat in the furnace heating system may cause problems with comfort levels and air circulation. Check to ensure the thermostat is on and that the temperature displayed is accurate. If not, a technician can help.

Continuous Running Blower

A continuous running blower may be as a result of the limit switch, fixing the limit switch will fix the problem.

Safety Switches

The safety switches on the furnace heating door prevent the burner and fan from coming on after removing the access panel. If the burner or fan run when the panel is open, replace the safety switch.

Having your furnace heating system inspected periodically is another way of fixing minor problems before they become major endeavors. Furnace technician and repair professionals are qualified to provide maintenance and repair services.

Benefits of Efficient Furnace Heating

Good Deals Heating and Cooling furnace heatingHigh-efficiency furnaces consume at least 30% less fuel than older model furnaces. These heaters typically have a lower BTU rating for heat output. Some newer models offer an annual fuel utilization efficiency rating of 97%.   Cleaning and repairing a high-efficiency furnace on a regular basis will keep the unit working correctly. This routine maintenance will reduce the furnace’s consumption of fuel and prevent carbon monoxide from entering the home. The home should be adequately insulated to make it as energy efficient as possible before installing a new furnace heating system.

The U.S. Department of Energy says 56% of the energy used in an average home comes from the heating and cooling system, 30% of which is from the heating component. High-efficiency furnaces produce heat more steadily. This HVAC systems are better at controlling the amount of air mixed with gas and vary the blower motor’s speed depending on what the house needs. These variable speed blowers are less noisy and do not drastically change the house’s temperature. Sealed combustion, the process of bringing all the combustion air from outside and mixing with fuel at a controlled rate, maximizes fuel heat.

Look for models that offer features such as a modulating burner that will continuously adjust heating levels in small doses to match the home’s comfort level. Many of these furnaces are tailored to match the home’s regional location. People who live in Philadelphia will have different heating needs versus people who live in Phoenix. Many high-efficiency furnaces are self-monitored, making the furnace’s set up and maintenance faster and easier.

An electrostatic filter can reduce the amount of dust that goes through the furnace. This filtering system can be an enormous relief to people with lung problems, such as asthma. High-efficiency heating systems do not have a pilot light instead they have either intermittent, direct spark ignition or hot surface ignition.

These high-efficiency systems are more expensive upfront than standard HVAC systems. But these units will save the customer’s money, in the long run, thanks to lower fuel costs over the furnace’s lifetime. An energy efficient systems can save the customer $40 for every $100 spent on fuel.  High-efficiency gas and electric furnaces can cost $4,400 to $4,600, and Oil-based ones can cost about $6,000.  Always choose a system that comes with a good warranty.

Maintenance Tips for Furnace Heating

Good Deals Heating and Cooling furnace heatingRegular maintenance is key to ensuring proper functionality, efficiency and a long lifespan of any home heating system. Regardless of the type of furnace heating system, there are a couple of things to consider in order keep it working at the optimum level. Mentioned in this article are some of the important maintenance tips.  Although the best approach is to hire a professional, some of following things can be done by the homeowner.

Note: It is always important to turn off the fuel and electrical supply before doing any work.

Filters

One of the most common problematic areas is the filter.  If the filter is dirty with accumulated debris, the airflow will be impeded. Blocking the airflow will reduce both the efficiency and the lifespan of the furnace heating system. To prevent airflow problems:

  • Regularly (at least once a month) examine the filters (particular if they are fiberglass)
  • Clean permanent filters on monthly basis
  • Electronic air cleaners should be cleaned every other month

Electrical System

Some furnace heating systems may have failures in their electrical systems. If the fuse blows repeatedly or the trip switch goes off, it is a definite sign of an electrical problem. Electrical issues should be handled by a qualified and experienced professional only.

Smell of Gas

If the furnace heating system runs on gas and there is a smell of gas within the house, the best thing to do is to get out of the house leaving the doors and windows open. Call 911 and report that you smell gas.

Yearly System Check

While it is important to carry out regular inspection work and light maintenance work by the homeowners, it is mandatory to get these units inspected by professionals once a year.  A professional will check for any leaks or potential issues from wear and tear.  It is a wise homeowner’s decision to get the furnace heating system serviced at the end of the heating season; service companies are likely to offer seasonal discounts during this period.

It is always better to track the performance of the furnace heater. The key is to address problems early.
