When should you call a heating contractor? While some heating and air issues don't require professional service, as a homeowner you need to understand when to contact an expert. If you're not sure what qualifies as a reason to call, take a look at the times you need to call an HVAC company ASAP.
A Strange Smell
Does your furnace use natural gas as a fuel source? Natural gas has a rotten egg odor added for detection. If you smell something rotten or a sulfur-like scent, turn the furnace off, open the windows, move outside to fresh air, and contact the HVAC technician immediately.
Keep in mind, natural gas is explosive. Avoid using electrical devices or lighting a flame until after the technician repairs and clears your furnace.
Natural gas isn't the only potentially hazardous problem. Carbon monoxide is a colorless, odorless gas that can cause serious illness, or worse if inhaled. Every home should have a carbon monoxide detector on each floor. If your carbon monoxide detector sounds, then move to fresh air immediately. Contact emergency services and an HVAC contractor.
The contractor can evaluate the furnace and repair it before you use it again. Like a carbon monoxide alarm, a smoke detector alarm is also a reason to call the HVAC professional. If this system smokes or has a burning smell, you need an expert to inspect it immediately.
Is your heater on? Provided your home's electricity isn't out, it's likely the HVAC system has a problem. If the furnace sounds like it works, but your home is still cold, your system requires professional help. Call the technician as soon as possible. The longer you run the system, the harder it will try to heat your home. This forces the heater to work harder and can cause excessive damage.
Even though most home heaters make some noises, outside of the blowing noise of forced-air heat, your system shouldn't seem loud. Excessive, new, or strange noises typically point to a problem. Unless there's an obvious reason for the noise, such as loose air filter, you need professional help. The technician can inspect your heater, diagnose the problem, and repair the system.
Whether you smell an odd odor, an alarm sounds, you have no heat, or the system makes loud noises, your furnace requires a professional repair. Never attempt a do-it-yourself approach to fix these problems. The heating contractor has the expertise and experience necessary right now.
