About this job

SwiftPro's note, in our words, on the problem in this review.

Three pieces went in on this job: a new water heater, a thermostatic mixing valve and a OneFlow TAC filter.

A new tank is worth protecting where the supply runs hard, because hardness builds scale on the bottom of a tank or inside a tankless heat exchanger, and the burner or element then works harder to push through it.

Depending on your utility, hardness here ranges from under 3 to about 11 grains per gallon, and 7 or more counts as hard.

The signs are crusty faucets, spotted glasses, and sediment collecting at the bottom of the tank.

Testing at your tap comes first: hardness, chlorine, sediment, rust and iron, pressure, and the age and shape of your heater.

Two houses on one street can test differently, so a neighbor's numbers don't settle yours.

Then you see the options next to each other, and doing nothing is one of them.

Whatever you pick, flush the new heater once a year to clear what settles in it.

Emergency service 24/7.

Dryer vent cleaning5 out of 5 stars

I was trying to dry my clothes, but my dryer just would not work. I believed that the heat trip was being activated, so I tried cleaning the vent myself. Well, I couldn’t get deep enough, so I had to call some professionals. They came as soon as they could, and cleaned out my dryer vent. …

Turned out that there was TONS of like solid dust chunks in there that was just completely blocking airflow. After that, my dryer worked fine.

Some time later they also installed a water filter under my sink so that I don’t have to drink the chlorine filled pool water the city gives us anymore. I highly recommend the swiftest of the pros!

Plumbing repair5 out of 5 stars

Tyler(?) the owner is very very consientious about what his staff does. He called me immediately after my first post (which I thought I had deleted) and I agreed to try again with a different representative. HTyson was out this morning around 8:00 A.M. and was much more personable than the previous person. …

His customer service skills were top notch. He took time to explain various items about the soft water/filtration system. He even chased down my dog who is a real escape artist and did one of his escapes as I opened the door. That was a great plus as he really didn't need to do that. I'm currently looking at prices to determine which system I will purchase. I would recommend them to anyone looking for plumbing,HVAC,softner etc needs.

We recently hired SwiftPro in Fairfax County, VA to install a reverse osmosis water filtration system, install a new toilet, and replace our outside hose bibs. They were super professional, courtesy, on time, and pleasant to work with. Plus they got the job done at a fair price. Thank you, Tyler, Moises, Oscar, and the entire SwiftPro team!!!
