"I had a tankless water heater installed but needed the gas line to be dug from the other side of the house for it to be connected. The job was complicated but Luke and his crew from Mr. Rooter did a great job! I would totally hire them again for any plumbing needs."

Heating and Air Conditioning questions, answered by experts

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

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.

There are a few things you can do to make your AC repair technician’s job easier and your home more comfortable while you wait for AC repair:

  • Cut back trees, shrubs, and weeds around the outdoor compressor 

  • Clear a pathway inside and outside to your AC components

  • Set up a ladder for attic access if necessary

  • Pull your window AC out of the window and place in an easily accessible spot

  • Supplement with fans and open windows to help keep your house comfortable

AC capacitors have a wide lifespan, ranging from five to 20 years, with an average of about 10 years. Many capacitors will last for the entire life of the air conditioning unit, and most homeowners only need to replace one once. A capacitor should only be replaced if an HVAC professional diagnoses a problem with it. Premature failure can be caused by overheating, power surges, or short circuits. You can help extend the life of your AC capacitor by scheduling regular AC maintenance each year.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
