Besides full-blown equipment failure, it can be tough for inexperienced homeowners to recognize when their furnace needs repair. Fortunately, as we mentioned earlier, furnaces often show off signs something is going on, including:
A Spike in Utility Bills
Were you surprised by how much your energy bills have gone up recently? Even though sudden cold spells can cause your monthly bill to surge, if your bills are significantly higher than they were a year ago, your furnace may be dealing with a problem that’s stopping it from working at full efficiency.
Does it feel too hot in one area of the family room, and too cold somewhere else? Uneven or inefficient heating is often a sign your furnace isn’t working as it should. This may be due to an internal component failure, gas leak or leaky ductwork. An HVAC technician can help determine whether repair or replacement services are your best option.
Any unusual or foul odors coming from your furnace should raise red flags. Mold and mildew smells could mean a small water leak is now a breeding ground for spores. Alternatively, a burning smell implies an electrical concern like exposed wiring. Any fire hazards should be inspected and resolved as quickly as possible.
A well-maintained furnace is usually pretty quiet aside from the minor noise of it starting and stopping. If you hear banging or rattling noises, there might be a loose or broken bolt. When something doesn’t sound right, get in touch with the HVAC technicians at A-1 United as soon as you can to avoid further damage.
Short cycling occurs when your furnace starts a cycle, stops before the set temperature is reached and then starts back up a short time later. Short cycling can lead to comfort issues, higher energy bills and excess wear and tear. Well-known causes include a dirty or clogged furnace filter, an oversized unit, a dirty pilot light or thermostat errors.
Is there a puddle forming around your furnace? This isn’t always a problem if it’s addressed quickly after you notice it. Water leaking from your heater often suggests a clogged or damaged condensate drain line.
