"I would absolutely not recommend Eco Electric Company. It took them nearly a month just to install a furnace — a job that should’ve been done in a few days. Their troubleshooting skills are seriously lacking, and I paid the price for it. Initially, they charged me $4,500 just to “level” the old furnace, claiming that would fix the issue. It didn’t. After wasting all that time and money, they came back and told me the furnace actually needed to be replaced — and asked for another $5,500 to do it. In total, I ended up paying $10,000 just to replace one furnace, all because they couldn’t properly diagnose the problem from the start. Completely unprofessional and frustrating experience. Stay far away."

We have been serving the Greater Puget Sound area since 1982. Today we serve all of King, Pierce, and Snohomish counties. South West focuses on customer service as the differentiating factor between our company and other plumbing, heating, air, and electric contractors in the area. Our expertise, support staff, and quality work will earn your business for years to come.

"We Had Southwest Plumbing come to our house to attatch a hose bib that my husband wasn’t able to do because of the angle of the piping. He had the crawl space totally accessible and plenty of room to it as well as cob webs etc cleaned out of there. Hose bib was already removed from house. We also had a new hose bib on hand. It took the plumber 7 min to do the job. They quoted 1048.00 and we assumed they would deduct a couple hundred off when the job was done, it could not have been easier for the plumber. Again 7 min job…….. I have reached out to them 3 times to talk to Andrew which I’m sure is a manager. He has NOT returned our call. A call back and parcial refund would make all the difference as the plumber did his job well. With assessing the job they were at our house a total of 50 minutes and it cost over a 1000.00, very unacceptable. We are hoping they will make this right."
