Puget Sound's Home Service Heroes! Offering Plumbing, HVAC, Electrical, Duct & Sewer Services Hunt’s Services is a certified and licensed plumbing, heating, cooling, electrical, duct and sewer services company. We offer same day repairs and emergency services, with over 2,600 five-star reviews by our customers in Tacoma, Federal Way, Auburn, Puyallup, South Hill, Kent, Bellevue, Redmond, Seattle, Olympia and the nearby areas. We take pride in serving King, Pierce and parts of Kitsap and Thurston Counties for both residential and commercial needs with honesty, integrity, and dedicated service.

"had a deeply frustrating experience with Hunt’s HVAC Services that reflects a serious lack of professionalism and customer care. They contacted me early last week to schedule service for my HVAC system, and I agreed to their preferred date—the following Monday. I received a confirmation email on Sunday and a reminder Monday morning for the upcoming afternoon appointment. I drove 1.5 hours to the service site, only to be met with confusion and poor communication. When I called at 12:30 to ask for a specific arrival time, I was told the technician would contact me 30 minutes before arriving—but they couldn’t give me a time estimate. I waited another 2.5 hours before receiving a call informing me that no technician would be coming at all. My only options were to reschedule or cancel. I asked to speak with a manager and was placed on long hold. Eventually, I was told the manager was “too busy” to speak with me and would call me later. That call never came. This experience was a complete waste of time and resources, and the lack of accountability was appalling. Hunt’s HVAC Services failed to honor their commitment, communicate effectively, or show basic courtesy. I strongly advise others to stay away from this business."

"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

"It is not often that a repair person comes to your home and performs above expectations. Michael, from Mainline Plumbing, did just that. He corrected the challenge of a sub flow kitchen faucet that has plagued us for several years. The plumber, who previously installed it said that it was what it should be. Once my wife used the corrected faucet, she kept saying, “I can’t believe it!”"

Water Softeners questions, answered by experts

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

Water softeners have many benefits. The most important one is converting previously hard water—water with too many minerals—to more usable, easier water. When we say easier water, we mean water that’s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water.

Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet.
