8 Signs That Your Heating System Needs Repair Or Replacement

For your furnace to run optimally, it requires routine maintenance. Our technicians at Air Doctorx Heating & Air Conditioning often come across systems that have been neglected, leading homeowners in Delaware and Eastern Shore Maryland to require furnace replacement earlier than expected. Regular furnace maintenance can help you avoid problems in the long run and can increase the longevity and performance of your unit. If your furnace continues to work efficiently and properly, your home and family will remain warm and comfortable throughout the winter.

Signs that indicate the furnace needs a tune-up.

High energy bills

Heating costs are on the rise, so it is always better to pay particular attention to how your heating costs are compared to those of the prior year. If you’ve used your furnace close to the same amount as you did during the same period last year, but your heating costs have increased significantly, it’s time to have your unit inspected by a professional.

Strange sounds

Normally, the furnace will make noise, especially when you switch it on for the first time after the summer. Turning on the furnace may emit a small pop or click before properly starting up. However, it can be of major concern if you hear noises such as scraping, grinding, rattling, or squeaking for an extended period. If your furnace produces these noises, search online for furnace installation near me—you’ll find our experts at Air Doctorx Heating & Air Conditioning! Call us at  (302) 492-1333 today!

Odd smells

If you find a foul odor coming from your heater or the vents surrounding it, this could indicate that the condensate drain is clogged. If this occurs, the drain will become contaminated with mold and slime, which can cause leaks and a decline in indoor air quality.

No heat flow

You may notice that the ductwork and registers in your home are not functioning properly, in addition to the fact that your home is suddenly cold and draughty. If there is no heat from your system and no air circulating through the ductwork, have your furnace repaired immediately.

Gas Leaks

If you smell gas leaks, you should contact an HVAC expert immediately so they can handle the situation and avoid furnace replacement in Delaware and Eastern Shore Maryland. Immediately turn off the furnace, as the gas is highly combustible, and even a single spark can inflict extensive property damage.

Short cycling

Short cycling refers to when your heating and cooling system cycles on and off too quickly. If the furnace cannot reach the required temperature, your system will have to spend twice as much work to produce the same quantity of heat. This continual pressure causes unnecessary strain and can hasten the need for early repairs.

Pilot lights are either orange or yellow

If you have any concerns, you should inspect the pilot light on your furnace. A blue flame should come from your pilot light. You should contact a heating professional immediately if the flame is any color other than blue.

Changes in air quality

Changes in air quality are typically a sign that your heating system is dirty and needs cleaning, maintenance, or repair. The buildup of dust and other impurities in a home’s HVAC system can also produce unpleasant odors. Air that smells musty or stale may also result from blocked or damaged vents.
