"Broke electrical line to yard light. Said they are not responsible. Also, someone there said to call back to arrange to get it fixed. When I did, was told they do not do electrical work in Champaign. My wife had informed the technician of underground wire before work began. In addition, can not close closet door because of Jack hammering that was done. As a result, dust was all throughout the house."

"Both the estimator Kevin the two installers who visited my home were very professional and kind. They answered all my questions and provided a very reasonable price for the installation of the attic insulation. I feel I was very informed on the federal rebate that was available for this installation, as well as on the recommendations of quantity of insulation I needed per residential standards and codes. I would recommend Anton and will use them in the future for my HVAC needs!"

Central a/c service or repairs FAQs

An AC capacitor provides the electrical energy needed to start and run your air conditioner's motors. It stores and releases electricity to keep the compressor and fans running smoothly. Without a functioning capacitor, your AC unit may not start or operate efficiently. If you notice problems with your AC unit, contact a professional to diagnose the problem and see if you need to replace your AC capacitor.

AC capacitors last between five and 15 years, with an average lifespan of ten years. Environmental conditions and system usage can affect their lifespan. Regular maintenance can help extend the life of your capacitor. When your replacement capacitor is installed, be sure to ask your AC technician about best practices for maintenance and ongoing service to keep your unit in good condition for as long as possible.

While you might save between $60 and $200 by replacing the capacitor yourself, it's not recommended unless you have electrical expertise and proper safety equipment. Replacing a capacitor involves risks like electric shock and potential damage to your AC unit. It's safer to hire a certified HVAC technician who ensures safe and accurate installation.

It's safest to have a qualified technician inspect your AC capacitor. If you decide to look at it yourself after turning off all power, you can carefully remove the front panel and check the capacitor for any visible issues. However, handling electrical components carries risks, so professional inspection is recommended.
