"Never having had to hire someone to fix my AC unit only to install it (and the company was not reputable), I had serious trust issues. Action was the only one to contact me of all the suggested companies. That made me even more suspicious! They were able to fit me in for the next day. Hmm, more hesitation. But I rested in Action's good reviews on HomeAdvisor and kept the appointment. I was so happy I did. Mike was fantastic. He was personable and extremely informative. He knows his AC and heat pumps really well. I look forward to having them back in a couple of weeks to clean my furnace and do some cleaning and troubleshooting on a Hearthstone gas fireplace. When one finds a company one can trust, well, stick with them and get what needs to be done, done. I am so happy to have done something so out of my nature, like trusting HomeAdvisor. Thank you, Action Plumbing, Heating, and Airconditioning!"

"Excellent service. I had a sump pump system put in 10 years ago by Rescon. Never had any problems with it, worked great. This weekend with all the rain the pump stopped working. I called there emergency line and a service technician called me back in less than an hour. They were at my house in less the 2 hours fixing my pump. They did charge me an emergency dispatch fee for the service call but I guess that s expected on a weekend. Overall it was excellent service and I am very happy I chose this company."

"pricing for a sump pump installation was on the higher end of quotes however the quality of work and the kindness of the person I talked to and how they fit me in in last minute and they call a few times to verity and go over everything was amazing. I would defiantly pay the little extra for the above and beyond service."

"I had a leaking faucet Andrew was quick to respond. We went over a couple options but i decided to go with a new faucet swap. Andrews pricing was very affordable, he showed up when he said he would he was clean and his work is high quality. I will definitely be using this business again for my plumbing needs."

Sump Pump Installation FAQs, answered by experts

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

You should be fine. Most high-grade grinder pumps have a 24-hour holding capacity within the tank. You can continue to use the facilities so long as the power outage does not stretch into days. In a worst-case scenario, attach a generator to the grinder pump, providing it has sufficient electric capacity.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.
