What’s Causing Gas Furnace Problems?

Gas furnace problems seem to become when when you need heat in your house. Since heating and air conditioning contribute to overall home comfort, it is important that we take care of our gas furnaces.

What causes gas furnace problems? What can homeowners do about them?

These are two popular gas furnace complaints homeowners share with HVAC experts.

Gas Furnace Problems Repair for Underperforming HVAC System

Signs for an under-performing gas furnace:

  • Poor heating temperature
  • Low indoor air quality
  • Frequent cycling
  • Low air feel
  • Irregular airflow

The best way to mend an under-performing HVAC system is with gas furnace maintenance.

Technically, gas furnace maintenance is not a repair. However, gas furnace maintenance attends to every need the furnace has and can solve many problematic behaviors homeowners don’t like.

For example, low indoor air quality comes from a dirty furnace. With gas furnace maintenance, your technicians perform an in-depth cleaning. By removing stubborn buildup and growths, the interior of the gas furnace is cleaner and healthier, so that the air passing through it stays clean too. In fact, a dirty gas furnace causes many problems. It is the root of high-energy bills, frequent system cycling and uneven heating.

When homeowners use their gas furnaces despite obvious issues, it does more harm than good. While homeowners may save time and money for now, these issues grow to serious repairs that cost big.

Gas Furnace Repair for High Energy Costs

What causes high-energy costs? Some culprits include:

  • Tears and leaks in the air duct system
  • Incompatible thermostat
  • Poor home insulation
  • Incorrectly sized gas furnace

However, for the average home, high-energy costs come down to two reasons. First, homes that are not prepared against heat loss waste a great deal of energy from heating. Second, the gas furnace needs a technical repair.

If the gas furnace is in need of repair, only a technician can assess and determine the root of the problem.

High-energy costs also come from a dirty gas furnace. If the air filter is clogged, old or overused, air cannot flow through the gas furnace. As a result, the gas furnace overheats and reacts differently to deal with the stress of change.

An unusual reason why homeowners may have high-energy costs is air duct tears. Leaks and tears in the air ducts are uncommon, but they do happen. Essentially, heated and cleaned air escapes through holes in the air ducts. Meanwhile, dirty air from the outside enters through the same holes. This contaminates home air with allergens and particles while foiling heating.

Troubleshooting Top Gas Furnace Problems

Homeowners can experience issues with their gas furnace and air for a variety of reasons. Because the central air system is so large and made up of many different parts, there’s a chance for problems to occur anywhere. Fortunately, there’s almost always a simple explanation to what ails your central heating and air.

Central Heating and Air Doesn’t Turn On

More often than not, central heating and air doesn’t turn on because the thermostat is set at the wrong temperature. With all that we do during the day, we often forget where the thermostat has last been set.

If your central heating and air doesn’t turn on, double check that the thermostat settings are where you want it, and either high or low enough to prompt heating and air conditioning.

If central heating and air doesn’t turn on still, the safety switch may have tripped. This happens when there is a large enough problem with the central air system that it has shut itself off. Central air systems do this to prevent accidents. In the event of a tripped safety switch, you’ll need the help of an HVAC technician.

Central Heating and Air Doesn’t Heat or Cool

When central heating and air doesn’t heat or cool, there can be many reasons why.

First, the condenser unit may be having issues. For example, the refrigerant may have a leak or is under low pressure. This results in air conditioning that is never as chilled as you like.

Second, the air filter may be overfilled. Dirty air filters restrict airflow, which means less air circulates through central heating and air.

Third, there may be a problem with the fire exchanger. This is rare, but because the fire exchanger is such a vital part of the heating process, damage to the fire exchanger will stunt heating. Turn off the central heating and air and wait for your HVAC contractor for assistance.

Central Heating and Air Doesn’t Feel Right

Central heating and air should feel and be comfortable. Sometimes, however, homeowners complain about air not feeling the way they like.

Central heating and air can smell or produce strange noises. Central heating and air can also feel dirty, heavy or sticky. Fortunately, there are plenty of ways to adjust your central heating and air to your lifestyle goals.

If your home central heating and air doesn’t feel right, it can be because of:

  • Low or incorrect internal settings
  • Punctured air ducts or dirty air filters
  • Microbiological growth
  • Poor insulation
  • Incorrectly sized central heating and air equipment
  • Incorrect humidity levels

Work with your HVAC provider to make these fixes and restore home air.
