Urgent heater issues aren’t common, but they do tend to happen at the least convenient — or comfortable — time. Suddenly being faced with some symptom that indicates a glitch or fault in the system during winter weather is exasperating. Urgent heater issues run the gamut from simple issues to something more complex. To ensure safe heating and competent repair, these problems require the expertise of a qualified HVAC service professional. Here are examples of urgent heater issues other than a total system breakdown.
Unusual Sounds
You’re accustomed to the soft sound of warm air circulating when the furnace cycles on. Any variation from that norm tends to draw attention fast. A screeching sound when the unit cycles on could be a loose or worn blower fan belt. A loud humming or buzzing sound, conversely, might be a blower motor that has seized up and overheated. Repeated clicking noises may indicate an electrical relay or solenoid in the system failing. Ignoring these noises could inflict more serious and expensive damage. Call for professional service ASAP.
Noticeable Odors
A normally functional furnace shouldn’t be smelly. Smells usually indicate urgent heater issues, with one exception: If the odor occurs after the unit has been off for some extended period, such as over the summer, an acrid smell of dust burning off furnace burners may be briefly noticeable. This odor should quickly dissipate, however, and not recur. Any other unidentified odors — and especially the pungent smell of natural gas — is an emergency. Shut down the unit and contact an HVAC professional immediately.
Circuit Breaker Trips
If you are utilizing electric space heaters, these units may draw more current than a particular household circuit is rated to provide. Consult an electrician. A circuit breaker that trips during operation of a gas-powered central heating system is an urgent heater issue likely related to the furnace blower fan — the major electrical component — and requires qualified HVAC service. In both cases, discontinue use of the unit until you get a professional opinion.
