"I am very unsatisfied with my experience. I called the office to talk about my projects and get a quote on the jobs that I needed completed. We discussed all three jobs. The office said this would take a day and quoted me a price. They charged me money to hold my appointment date. A month went by, I had to call the office the day before the appointment to make sure that someone was still going to be arriving the next day. The appointment was scheduled to start at 8:00 am. The handyman came to my house at 12:45. He looked at the jobs that were to be completed and said that he could only finish one of them and asked which of the three I would like him to do. He went out to buy materials and returned back to my house sometime around 3:00. He never even fully finished one of the jobs. He left my house at 5:30 and I was charged over $1000. I was also charged for a gallon of paint that he never even used because the job was never completed. I asked if someone would be calling to schedule the work to be finished. He assured me that someone would be calling. No one ever called or returned."

Heating and Air Conditioning questions, answered by experts

If your AC unit isn’t cooling and you haven’t figured out why, there are a few good reasons to turn it off ASAP. The source of the issue, whether that be leaking refrigerant or a broken compressor, will worsen and cause more damage to the overall unit the longer the machine is allowed to run. When in doubt, shut it down until you or an AC pro can ensure everything is working properly.

It’s critical to use the right size AC for your space and not go too small or too big. If you purchase an undersized unit, it won’t properly cool your house, and it has to work harder to reach the optimal temperature. This will eventually wear your unit out. An oversized unit can spell trouble because it will turn off and on more frequently, which also wears out your AC unit. An oversized unit also causes humidity in the home.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

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

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.
