What to Know About Heater Maintenance: The 5 Most Common Heating Problems
1-800-Plumber +Air of Fairfield County

You do not want to deal with a broken heating system during chilly winter months. If your heating system isn't working correctly, you need to get things working again and fast. Do you do it yourself or call a professional?

First, you need to know the differences between a furnace and a modern HVAC unit. A furnace is typically powered by natural gas, oil, or propane and ignites the fuel to generate heat in a combustion chamber. The heated air is then blown through ductwork and distributed throughout the home via vents or registers. Furnaces are typically used in colder climates and are designed solely for heating.

On the other hand, a modern electric HVAC system uses electricity to power a heat pump, which extracts heat from the air outside and transfers it inside to heat the home. In addition to heating, a modern electric HVAC system can cool and dehumidify the home during warmer months. Electric HVAC systems are more energy-efficient than furnaces and can save homeowners money on their energy bills over time.

Regardless of what your home has, your heating system should maintain a comfortable temperature inside your home. If it blows too much but doesn't maintain the temperature, you're wasting energy (and money) while suffering in a cold house. You could also risk your health from carbon monoxide poisoning or breathing dirty air from a broken furnace.

1. Heating System Doesn't Ignite

Your heating unit won't blow warm air without a "lit" pilot burner. While it is a tiny flame, the pilot burner ignites the gas from the burner to generate warm air.

If you determine your heating system's pilot light isn't lit, your next move should be careful. If you are experienced and know how to relight a pilot, good for you. Problem solved. If you're not experienced in working with home heating systems, get help. Gas explosions can really ruin your day.

You can do some things even if you're a novice at troubleshooting heating systems. Start with a smell test. If you smell gas, do not try to relight the pilot fire. Call your local Shelton heating professional.

2. Heater Does Not Blow Warm Air

Again, this might be an issue with the pilot burner. In addition, you may have a blocked filter or a wrong thermostat setting. Do you know how to tell which issue you have? 1-800 Plumber knows and can help if you call us.

Ensure your thermostat is set to "heat" and the temperature is high enough to activate the heating system. Check the air filter. You will want to change it if the filter is old or dirty.

If those steps do not get warm air flowing when your heating system comes on, it's time to call a home heating professional like 1-800 Plumber in Shelton.

3. Blower is not Functional

You may have an issue if you listen closely to your furnace when it should be running and do not hear air blowing through the vents. Do the following test to troubleshoot

  • Check the breaker to ensure the heater has power

  • Readjust the thermostat temperature level

  • Your thermostat fan should be set

If the fan setup does not trigger the blower, you may require repair work for the blower motor.

4. Furnace Cycles on and off

A clogged filter could be the culprit for a furnace that repeatedly cycles on and off. Replace the filter and adjust the thermostat setting to make sure the temperature is not too high. Call your Shelton heating professionals if the furnace continues to cycle off and on rapidly.

5. Temperature Is Inconsistent

Is one room colder than the others? Check the vents. A closed or blocked vent won't allow the furnace to circulate air effectively through your home. For two-story homes, poor intake design might be pulling all of your warm air upstairs leaving downstairs much colder than upstairs. This is a structural issue that can be resolved by changing where cold air is drawn back into the system.
