Highly recommend the pros at Swift Pro. Our technician, Elvis, was professional, thorough, and very courteous. Despite having to install a whole home humidifier on a Friday evening, he took his time and really did a fantastic job on the installation. Elvis left the building around 8PM and cleaned up the work area before departing.

About this job
SwiftPro's note, in our words, on the problem in this review.
This one was a whole home humidifier, installed on a Friday evening.
People want one for winter, since cold outside air carries almost no moisture and running the heat dries it out more.
You notice it as a shock off every doorknob, gaps opening between floorboards, a piano slipping out of tune, or a house that feels colder than the thermostat claims.
Before you buy, set a hygrometer in the living room on a cold day with the heat on.
The EPA puts indoor humidity at 30 to 50 percent, so a 35 means you can skip it, and an 18 explains the shocks and the floors.
The install means tapping a nearby supply pipe with its own shutoff, running a drain, cutting the unit into the ductwork and sealing it, and wiring a humidistat to the furnace so it only adds moisture while warm air is moving.
With the plumbing close by, it's about half a day.
After that, change the water panel every fall; left alone for years, it scales over, stops working and starts dribbling where it shouldn't.
Emergency service 24/7.

Excellent HVAC service for a fair and reasonable price. Moises Rojas fixed my home’s whole house humidifier, which I had no idea wasn’t working for over two years since moving into this house, and now the air in my home is very comfortable.
Moisés’ HVAC work is exceptional. He installed a return that completely resolved a static build up problem we had. He also installed a whole house humidifier that we are very pleased with. I’d trust SwiftPro for any of my HVAC needs!
SwiftPro is very responsive and timely. They have great customer service. I reached out to them after 6 pm when our AC unit stopped cooling the house and they had someone out the next morning. We have used both their plumbing and their HVAC services. More on that specifically below. …

Jimbo was very helpful and informative. We initially had him look at something we were getting a second opinion about and he saved us from spending a lot of money that the first plumber told us we needed done. He showed us exactly what the issue was (which was not what the first plumber told us it was) and how a much simpler and cheaper solution resolved the issue. We had him look at something other plumbing things while he was here and he explained how certain things worked and why. He was also open to answering a lot of questions in a nice and helpful manner. I would highly recommend him and SwiftPro plumbing. We went through 3 plumbing companies before finding SwiftPro.
Eddy Hernandez did a great job when our AC unit stopped cooling the house. He also educated us on some basic HVAC and humidifier things that we can do ourselves to make things run smoother) and in one case with less effort on our part. They also replaced our air scrubber and helpful information related to that as well.
Everyone we dealt with on the phone or in person was very pleasant. Both the plumbing and HVAC had the parts on their trucks needed to address the issues we called them about.
