"I couldn?t be happier with the job Cameron did installing my A/C. From the very start, he was professional, knowledgeable, and worked with great attention to detail. He made sure everything was done right and took the time to explain the process along the way. What really impressed me - was how by the end of the job, Cameron treated me less like just another customer and more like a family friend. It?s rare to find someone who combines skill with genuine care like that. I?d highly recommend Cameron to anyone!"

"I had an issue with my furnace, so I requested help through Angi. Miki called me within 10 min and offered to come straight out to my house to diagnose the problem. After stopping at the store to pickup a new furnace filter for me, he showed up and got to work. I was very impressed with how fast he addressed the problem and fixed it. He then went on and showed me the type of filters to buy and what to stay away from. My furnace is very old and as a result will need to be replaced sometime in the next couple years. So when I change the filter he showed me what to look for so I know when the furnace needs to be replaced. I really liked this guy he came out right away, fixed furnace, offered me free professional advice and charged me next to nothing. He is very honest and reliable. I would and will highly recommend to anyone who seeks a heating/AC professional to work on their project!"

Heating and Air Conditioning questions, answered by experts

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.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

When deciding whether to repair or replace your air conditioner, several factors should be considered. It is generally worth repairing the unit if it's less than 10 years old, the warranty is still active, and you're dealing with a one-off issue. Most central AC units last about 15 years, while window units last 8 to 10 years. If your unit is approaching or has surpassed the 10-year mark and requires frequent or costly repairs (e.g., over $5,000), replacement is often the more sensible long-term investment. For older, inefficient, or out-of-warranty units experiencing multiple problems, replacing it is typically the better choice.

You can buy a new AC capacitor through most big-box home improvement stores, from an HVAC contractor, or from the manufacturer. Use the model number of your air conditioning unit to make sure you purchase the right part for your unit. Also, keep in mind that the cost of this type of part can vary significantly depending on who you purchase it from, so shop around to get the best price.
