"This young man was very efficient and communicative. He was extremely conscientious and exact about his work. He was considerate about caring for our home by carefully closing the door and wearing foot covers on the carpet. He installed a window unit in an upstairs bathroom. Did an excellent job. Would hire him again if needed."

Heating and Air Conditioning FAQs, answered by experts

There are several AC unit problems to troubleshoot, but luckily you can identify them by keeping a close eye on your system. Look out for the following signs that your AC needs repair:

  • Unusual noises during operation

  • AC unit blows warm air

  • AC unit doesn’t come on or turn off with temperature changes

  • Strange odors come through the vents

  • AC unit cycles on and off rapidly

  • Indoor air is more humid or less comfortable than usual

  • AC unit keeps tripping your breaker

  • Fan in the outdoor compressor doesn’t operate when the AC is on

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

An HVAC system typically lasts between 10 and 30 years, with an average lifespan of 15 to 25 years. The longevity of the system is influenced by factors such as the quality of the unit, usage frequency, local climate, and how well it is maintained. Regular maintenance, including cleaning, filter replacements, and professional inspections, can help maximize its lifespan. Different components within the system have varying life expectancies. For example:

  • Furnaces: 15 to 30 years

  • Boilers: 20 to 35 years

  • Air Conditioners (AC units): 12 to 20 years

  • Heat Pumps: 10 to 20 years

  • Ductless Mini-Splits: 10 to 30 years

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
