Christianson AC & Plumbing

I bought a new-build home 11 months ago and Christianson installed the HVAC and the plumbing. Thus far I have not interacted with them much. I will be contacting them to set up my annual check up for May.

Just OK - Carrier equipment is great. Service is pretty good. Replacement system install was pretty bad. Will need Heat Pump unit soon and looking for alternatives.

This is a great company! Quality service and hard working quality people. The sales rep Paul explained everything and made the process seamless. I felt like every concern I had was address and after install they swept up and cleaned the area. I've been a loyal customer for awhile because the people there care about their customers. I would highly recommend them.

KB Home - new construction
November 16, 2020
Christianson was the HVAC subcontractor for my new KB Home. We monitored the construction of our new home and was pleased with the professionalism and expertise of the Christianson employees we met along the way. When we moved in, everything was working perfectly. We have been very satisfied. Although we didn't have the opportunity to choose our HVAC provider, we're glad KB chose them. We will likely reach out in the spring to start an annual maintenance plan with them. We would also recommend Christianson.

Could have been better!
August 14, 2020
The problem occurred when the technicians were in my attic installing the new coil and all of a sudden water started pouring from the air conditioning vent in one of our rooms; when I saw the water, I climbed the ladder to the attic and yelled to the lead tech that water was coming in on our table and on to the hardwood flooring; a rug was in the center of the floor and it was wet also. He said he had cut a hose and the water got away from him; he stopped the water quickly, but we still had water on the three surfaces noted above. If we had not seen this happening as soon as it started, we could have have had a real disaster on our hands. As it was, we were able to wipe up the water and it did not do any damage. However, it should not have happened at all.

New home purchase 2 weeks in, the a.c. wakes me in the middle of the night making terrible noises. Called emergency #, left message. Per message was to receive call back in 1 hour, it was more like 2. The tech arrived about 6 hours later, it was a Sunday. The problem was the filter was clogged. How could the builder not know that working with a.c. on would clog the filter and replace before new homeowner moved in.

Installation of Carrier AC/heating system to replace previously installed product
August 08, 2017
The installation by Christianson was professional and seemed to be well done. I cannot rate the system yet because I have not had a Carrier product before. I hope it turns out to be a high\-performing product that lasts longer than the 11 years my previous system lasted.

Great New Home....Great New Service
April 19, 2017
We moved into our new home a few months ago. I had to call Christianson to acquire the serial and model numbers for my unit so I could go online and register the units. I talked with 2 different ladies and unfortunately I did not write the name of the first one who was extremely helpful with the numbers. I called back to ask a few more questions and Holly helped me and even suggested I call Carrier with a specific question about the warranty time (which I did and they were equally helpful). All in all I had a wonderful experience today and am thankful for the opportunity to write about it.

New System Rocks
April 17, 2017
We've had service with Christianson A/C\-Plumbing since we bought our new house nearly 9 years ago. They have always been on time and very professional. The quality of their work is great and that's why we've selected them each time as our service provider for our A/C requirements. We recently discovered we had a cracked drain pan and discovered the cost of the repair would have been nearly 1/5th of the cost of a new system altogether. We had just paid a service contract and had to replace an electrical switch but we were informed we'd have that cost fully refunded if we bought a new system. We elected to go with the new system given the cost to repair ratio and the age of our old system. We could not be more pleased with the quality of the work which involved a very difficult to fit air handler system in the attic of the house. The new model is an upgrade to our old unit and we're confident we'll have lower utility bills. I'd recommend both Christianson and Carrier products to all our friends and family.

First it would have been nice if the builder informed us we had to go on line and register each item. AC did not work upon move in or during the walkthrough inspection. I am not an AC person but the two of us after 2 trips finally Found the root cause. A loose connection in the compressor. No problem since loose connection fixed.
