"In the middle of a heat wave my AC broke down during the night. I called a company I have used previously, but they weren't able to get to me for at least a week. While searching for a repairman using an app Circumvent contacted me and would come that day by 6 pm. The technician was able to come earlier. He found the issues right away and was able to repair my AC in less than an hour. The price was fair. He explained everything to me before proceeding."

"torn between 2 &4 stars but went with 2 only because I feel the cost exceeded in my opinion a reasonable cost to replace with a basic 40-gallon electric hot water heater based on the cost I paid two months ago to have a new eclectic 70-gallon high efficiency heat pump water heater and expansion tank installed. We had no time to shop around.... 4 stars for the prompt repair and 2 stars on the pricing."

Family owned handyman services. Licensed and fully insured. Quality workmanship. We guarantee it is done right the first time.

"Could not have been a worse experience. Hired to replace door hardware (knobs and hinges). Simple job for anyone. I was told by owner that "they'll make everything perfect ". Expected a few hours...it took two guys four hours by which time I just wanted them out. Checked things as they were working and pointed out multiple problems along the way. English communication was clearly not working. They did not know how to adjust doors by bending hinges (the correct way) and instead pounded on the door jams and sunk visible three-inch screws into one to adjust it. The front door was the worst and needed the doorknob hole enlarged by 1/8 inch. The solution was to use a Sawzall on both the knob and deadbolt holes - I wish I could attach photos here!! Ruined the door. It can never have a standard round knob again because of the hack job. Told owner, scheduled appointment. He didn't show and didn’t respond to texts. Small Claims Court is next to replace the front door. Don’t hire!"

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.
