Heating and Air Conditioning questions, answered by experts

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

Indications of an HVAC problem include inconsistent heating or cooling throughout your home, unpredictable temperature changes, or inadequate air flow from vents. Abnormal sounds such as grinding, banging, or hissing, and unpleasant smells like mustiness or burning are also potential warning signs. A rise in energy costs without an increase in usage may also imply decreased efficiency. An HVAC system that frequently cycles on and off or cannot maintain a stable temperature is malfunctioning.

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance
