They are supposed to be air conditioning company but I've been sweating for almost two months now in my new home. Stay away from them!

Easily the worst HVAC/plumbing company I've ever had the displeasure of dealing with. After four different visits across FOURTEEN DAYS, our system is still not cooling. We were the last stop of the day for each of the three different techs who visited us (one was here twice) and because of this they were always in a hurry to wrap things up and go home, even if the job wasn't finished.

I have been in this apartment in temperatures of 83+ degrees for TWO WEEKS thanks to these unprofessional, incompetent con artists. If I was you, I'd take your money literally ANYWHERE else instead of Christianson.

Christianson installed the AC unit in our two year old home. We've had multiple issues with it not heating/cooling the bedrooms properly. Each time, they told us that it's normal for our unit not to heat/cool the bedrooms, and to use emergency heat setting in winter. Today, our two year old motor died due to the unit being too small for our home. I called them and they told me 80 degrees in the home is not bad, and normal for such a hot day.

I said that it had been 80 all morning, even when it was not hot out. She said that it may be our air filters, but if I insisted, they could come look at it four days from now. I said that it is 106 out today and we have a four month old baby in the home. She told me to call someone else and hung up on me. I called someone else as suggested and the motor was replaced same day.

Critical: Professionalism, Punctuality, Responsiveness They do not communicate properly, finally came to install weeks late and they didn't even if is the job. The worst part is they didn't say anything about not finishing it and now they won't respond. Do not use them. Service: HVAC duct & vent installation

Appalled! Christianson was the plumber used by our builder so they did all plumbing, hot water heaters, back flow valves etc. We moved in in Dec. 2019. Now our hot water heater is out. It took 10 days to get on their schedule. Once they were here, they could not fix it. They are the ones who provided and installed the AO Smith unit in our house. I was told they install them but don't repair many of them.

The came back 3 times with different parts and were unable to get it going. By then I had reached out to Jerry-(service manager at Christianson) and the manufacturer (AO Smith)of the hot water heater. AO Smith said they were concerned that Christianson was not able to fix it. They wanted to send their own tech out to look at it. He came the next day and was able to fix it.

He then wrote a report and sent it to Christianson. Jerry from Christianson called us the next day and was extremely RUDE and mad at what AO Smith said in their report. Jerry told us not to call them(Christianson) to service our plumbing again. Wow! Maybe if they knew how to service the products they sell, we wouldn't be in this situation!

I used to think that Christianson was the last of the honest contractors. No longer. I guess all good things must come to an end. Uncaring, money grubbing, lazy, and I'm afraid, LYING. I hired an inspector, who said that the AC system was not working correctly, so I hired Christiansen to come fix it; they charged several hundred dollars to come out, and said "everything is fine".

Now summer is upon us, and the thing can't even drop the temperature 10° inside. THIS IS TEXAS! AC is LIFE or death! Rather than admit that they screwed up, and hightail it back to fix the system they didn't diagnose properly, they want another hundred dollars just to come by. I'm DONE. I was a potential customer for multiple locations. I'm glad I know who not to trust before dumping000S more dollars into this pit. Now, the arduous process of finding a reliable, HONEST AC contractor begins again. sigh

They did not show up and do the job they were contracted to do. They kept lying and saying they were coming fast forward to 2 months later and they finally came but did not even finish the job. Not only that they did not even tell anyone they did not finish it. Mind you this is a whole piece of an HVAC system that is noticeable. They have not responded for two weeks now and the job is still not completed. DO NOT USE THEM!

We bought a brand new house in 2019 so the HVAC system installed by Christianson AC is not very old. The system is under warranty as far as most parts but labor is not. We had them come out to find out why our house is not heating. The technician came out, said he did a temporary fix but had to order the part and charged us $95. We were called a couple of days later to see if we wanted to have them order the part and install it.

We said yes. The part came in a few days later and scheduled him to come out to replace it. After spending about 10 minutes installing it and $200 later he said he was done. That night we still had no heat. Same issues with the furnace. So for starters, I do not believe their technicians should not be trusted to troubleshoot or service their systems.

We also called Kurt to discuss the issue early in the day after leaving him a voice mail and he does not feel it is important to return calls which matches up with poor customer service. I would not recommend this company to anyone!

I called to see if I could schedule an appointment to have their AC team come and look at my system to see if it's working properly due to having higher temperatures upstairs. My downstairs will be set at 68-69 and the upstairs will be 82+ at times. I understand heat rises but wanted to make sure the system was working properly to have piece of mind as my house is just over a year old since we closed on this new build.

She was quick to say "unfortunately there's nothing we can do because heat rises". Thanks for being such a company, I'll make sure to use another company in the future.

Disappointing to say the least. We have had ongoing issues after this Company installed a new air conditioning system in our home. Today, we found pieces of fiber glass insulation in our son's crib that came from the HVAC vent above the crib. We will never again use or suggest using this Company for those expecting professional service.

Christianson sent a Plummer to my elderly mothers house to check on a leak she had. The Plummer barely looked around and claimed the leak was coming from the AC unit that was located in the attic and scheduled an AC tech to come out. One was not available for 4 days which means she would be without water for 4 days since it had to be cut off to. stop the leak.

Once she informed me of this I called Christianson on her behalf. Her AC unit is not in her attic. I had another AC company come out the same day and was told that the leak was in the wall and was not an AC issue. Christianson refused to send the Plummer back out to check again and said she had to wait for the AC tech which would be in 4 days. This is unacceptable when she already paid the $150 free for the Plummer to come out. I canceled the appointment and called anther Plumbing company that could come out the same day.

Horrible customer service. Our AC went out on a Sunday and when I called I was told they would come the following day between 8am and noon to fix it. We got a call at 9am that they would be coming by, but no one showed. The tech told us they had been knocking bit no one was answering. Turns out they never updated our address and sent the tech to the wrong house.

We called the office to update our address and they then told us they had sent the tech to the next stop, and now we were moved to the last stop of the day, even though it was their fault. We never got an apology from them for messing up our appointment and got the run around any time we called to get an ETA. With two little kids, we couldn't stay in a house that was 90+ degrees.

By the time 6pm rolled around they still hadn't shown up. We ended up calling a different company to come out because of how horrible this was. I understand mistakes happen, but not apologizing and putting us at the end of the day was not the answer. I will not be using them again after this.

Unreliable and unhelpful, call Airtron instead. My AC went out on a Sunday afternoon, I called Christianson up and they said the soonest they could make it was first thing Monday morning. I heard nothing back from them until about 11am on Monday and it was the tech calling saying they have been knocking on my front door and no one was answering. I go out and look and no one is at my house.

The person who scheduled the service put in the wrong address. The tech said he had to cancel the ticket and move on (despite the fact that he was only about 2miles away) and that the office would call me. Their schedule person called and told me they're re-entering my info but that I was being put at the end of the queue for that day (even though this was their mistake).

Around 5pm I call again since I still hadn't heard from them (my house was now about 90 inside) and I was told that my appoint would be handled anytime from 1pm to close of day, at which point I was told close of day was 5pm (about 5min from then). Finally at 6pm, I still hadn't heard from a tech or the office so I called and just canceled the visit.

I have a 2 month old and a 2 year old so we needed to now leave to get a hotel because the house was way to hot for them to stay in. Clearly Christianson didn't want my business and I didn't want to give them my money. I called Airtron and they sent someone out that evening.

The A/C had stopped blowing cold air on Saturday morning. Christianson had done the install of our unit (new home build) so I called and they were able to service it three hours later. David was friendly and efficient. He quickly diagnosed the issue (broken capacitor), had a replacement part in his truck, and replaced it. Maybe it's because they did the install and know to have those parts, or we got lucky, or they're always super prepared with parts on hand, regardless, it was the best A/C repair experience we've ever had. Plus the fee was extremely reasonable considering it was a weekend and short notice.

I had a bad experience with a prior A/C Heating company. They were incompetent and unprofessional. But when I called Christianson A/C and heating it was just the opposite. They came and saved the day! They showed up earlier than I expected, knowledgeable, professional, and highly competent. I highly recommend this company for your A/C and Heating.

I am currently recuperating from a major surgery. Room that I am staying has no AC, they came out and found that one part was broken and it is in stock. For some reason they have to schedule someone else to come out and replace said part on 7-12-21. Almost 3 weeks after the original date. They reached out and offered a new date of next week. I'm happy with this. Christiansen has restored my faith in their business. They are a honest company, I was misinformed of the issues at hand. I'm sorry if this caused any problems for them. Jessica

DO NOT USE! I wish there was an option for zero stars. For being as big a company as they are, you would think they'd be a little faster. I normally would not have even called this company, but since our home is under warranty, this is unfortunately who they use. They couldn't come out the first day our a/c went out, so we had to wait another day. Took off work only to have a tech come out and tell us it would be ANOTHER day for them to order the part. You're a huge company and you don't have the part?! And now we must take off another day of work. Christianson is a joke!

Whoever Emily is at this company needs a serious lesson in customer service. We had texted in the morning that we were leaving a key under the mat so the tech could access the property. At 3:30 pm I got a call they would arrive in 30 min. My boyfriend happened to be off and arrived by 4:02 pm. No one ever arrived and after hours of waiting and calls and texts inquiring where the tech was Emily called me and stated we missed the technician and they left because no one was home.

Come to find out the tech had got here at 3:30 (this is when I got the call they'd be here in 30, which simple math means they'd be here at 4) and left at 3:55. After clearly expressing my frustration Emily sarcastically stated "well I'm sorry we didn't wait another 5 min". I was completely blown away by her rudeness and lack of ability to deescalate the situation. Additionally how she tried to throw the blame onto us. Zero understanding or acknowledgement of their error.

I informed her her attitude was not appreciated and I hope whoever is her boss offers a coaching session of some sort. There clearly is a gap in communication in this company because no one informed the tech there was a key and the dispatcher also was not given the correct arrival time.

I have done business with this company both H&AC and plumbing for 10 years. They still have a $99.95 maintenance for H&AC so I use them each season-their scheduling has gotten very bad in the past year or so. Definitely need new employees. I have rescheduled my AC check for the 3rd time just a while ago as the technician didn't show for this morning's appt & no one bothered to contact me saying there was a "scheduling mishap".

This also happened a year or so ago & I got an apology from the service mgr. & stayed with them-no more. They show up May 26th for the last time only because I have already paid them. Unless you have all day to wait, with no courtesy call if they are late/no show, go with another company. I plan to do just that.

I called with a clogged sink, two dripping sinks and a slow drain. The clogged sink and slow drain were fixed, but the two dripping sinks are still dripping. the plumbers sent out said it was our water temperature (?). I finally just cut it off because it seemed like there was no conclusion to the faucets dripping. I left three stars bc I'm just happy the sink was at least cleared same day, but I wonder if I could have tackled that with a sink plunger.

My water heater bit the dust so I called Christianson to see if it could be repaired. As I feared, the unit was pronounced DOA. I elected to replace it with a new tankless unit and was shocked to learn that my plumber Jeff would be able to source a new Navien unit and could stay to install it that same afternoon! While Jeff dismantled and removed the old heater a helper picked up the new one and drove to my house with it.

The two guys worked late to get the heater installed and everything worked beautifully. Both Jeff and Joseph were professional and courteous and answered all my questions. This deal couldn't have gone much better. A++++++

If you value your time, don't schedule with this company. They over extend their technicians. This is the second time I had a 4 hour block and sat at home wasting time waiting for them to call 40 mins prior to the end time stating they were unable to make it and could I wait another hour. Sure. I can wait another hour. Then they notify me that. it's gonna be a little longer than an hour.

What's the point of having appointments if you can't keep them. The actual service is fine but the inability to stay on time or at least communicate that you're gonna be late MUCH sooner isn't worth the hassle.

I called to get prices on hot water heater installation and they were by far the cheapest option. I must say that it didn't feel like a cheap install! They were very professional, quick, and thorough. They even took a separate minute to fix a squeaky toilet handle that my wife constantly complains about! I would definitely call them again for any of my plumbing needs!

We called during the freeze with a broken pipe that had us shut down all water to the house. They put us on their wait list on Friday and called on a Sunday morning and came by! Jeff swooped in and saved us this morning with great skilled service. Uber-competent, helpful, polite, and efficient. Dug into the wall, Fixed our broken pipe, checked on us while we turned everything back on! Love them! Recommending them to all my friends! Five star!

Their technician took off his mask and spit in our kitchen sink when he was talking to us. I could say that he did it on purpose. I have never seen any disrespectful behavior like this before. They left without even try to fix the plumbing issue. Our house has one year warranty and they are in charge of fixing plumbing issues here but they don't do anything. I am done with them! We are going to hire another company. Better to pay money than wasting the time and dealing with these people!

I would recommend to everyone I know. To keep everything running smoothly to give that piece of mind. It was easy to schedule, the technicians were there when they said they would be for both the summer and winter tune up. And the gentleman even helped me push a car that had gotten a flat tire out of the way and then back after he was done. Over and above service!

We just moved into our new (build) home 5 days ago and our heat wasn't working so I called Christianson since they installed our two HVAC during the build. Christianson told me that since our builder didn't request to have the heat turned on I needed to call my builder and have the builder call them. Not the best customer service as they could've called the builder to work things out but they rather have their paying customer take extra steps.

I requested that a manager call me and never received a call back till this day. I called my builder and they worked things out and a day later Christianson sent someone out to turn our heat on. Fast forward to today one of my iDevices thermostats is power cycling on and off and I am not able to adjust the temperature. So I call Christianson again and get the run around. I'm told to watch the videos so I know how to program the thermostat.

I explain to the rude lady that I programmed the other one downstairs so I know what I'm doing. She continues to tell me that I need to try again and to send them a video so they can see what's going on. I sent the video of the defective thermostat around 10AM and asked to speak with a manager and was told they were busy. It's now 8PM and no call, no reply back to email.

This is par for the course and clearly Christianson doesn't care. They got their money and I'm stuck with horrible customer and a malfunctioning thermostat. *Update* Our builder Scott Felder was able to replace our faulty thermostat on 1/20 (Thank you!) which we greatly appreciate. All HVAC issues have now been addressed and cared for.

We have used Christian for the past four years. Since our home is new construction we signed up for the yearly maintenance program. In that time we have spent over 700.00 on our system for parts not covered by warranty. We had a maintenance team come out last week and gave us a 100% on our A/C heating system. This past week when we went to turn on our heat, no heat.

We called Christianson and the maintenance team came back out and charged us 146.00 for a bad coil. When I asked the technician if I could have the old part he told me I couldn't have it. I find that very suspect why they were want to keep a part that wasn't working properly. We have decided to find another company. We no longer find them trustworthy and reliable.

We had our 2-zone control board go out in April while under factory/part warranty. They came and replaced it for something like $200 for just labor, which was cheaper than the single other competitor I had provide a quote (gotta check the box/ get a 2nd opinion right?). We then went ahead and booked the twice a year maintenance program with them since I genuinely liked the guy who came out and our HVAC system is hitting 5 years old soon.

They came back and did the air conditioning spring cleaning part about a week or two later. You pay for the two part service up front. We get a notice in October it's time for the heater portion of the two part maintenance plan. It hadn't gotten cold so we put it off an extra month. Finally we scheduled it and turn the heater on and discover our heater isn't working at all.

They come out and say 'whoever replaced the board' didn't wire it correctly. Two of the wires were flipped so the signals weren't properly telling the heater to engage. We informed them they were the ones who did the replacement, so they fixed it and did the heater cleaning portion of the maintenance program and we all moved on.

Everything now seems to be working. This service guy was not the same individual as in April but also really personable and polite. The service overall is quick. The price isn't bad. But I would have preferred they wire the parts properly the first time instead of me discovering issues 7 months down the line. If we weren't part of the maintenance program I'm not sure if they would have tried to charge us for a diagnostic visit and labor, but I would hope not. I wish I could give them 4.5 stars because the service guys are all really nice and personable (and clean/covered during covid).

The realty company who manages the house we lease uses Christianson for plumbing and AC. This is not the company we would choose. The technician is rude and apparently thinks that he doesn't need to explain what he's doing or why. He also doesn't know who his manager is or who we should talk to with questions. However the main issue is that this company does not communicate.

They told me a part was needed to repair the A/C, it had to be overnighted and someone would be out first thing in the morning. At 11am I had to call for an update, they said the technician was out on a job and would come afterwards. At 2pm there was still no update or communication. The manager dismissed the behavior of the technician and simply stated they do not know how long jobs take nor can they give any accurate ETAs. Do not recommend this company at all.

This is the company to call if you want GREAT service from an honest reputable company. After having a terrible experience during one of the hottest weeks in Texas with a different company ---Steven Doepke from Christianson saved us. They replaced our entire HVAC system on literally a days notice. Somehow Steven managed to squeeze us in and saved us after almost a week of temps in the mid 80s in our home.

We suffered for a week dealing with One Guard Home warranty (now cancelled) and the dishonest company they referred us too. We should have called Christianson to begin with--we've worked with them before and knew them to be good. But that stupid home warranty! Don't use home warranty's.call a reputable dealer like Christianson!

I called Christianson AC/plumbing, Round Rock TX to service my AC. Guy came out spent 2 minutes in the attic with the AC, then said 'maintenance' was finished. Told me to change the air filters and would be back. He said he was 99% sure the problem was dirty air filters and a 'frozen evaporator'. Strange, AC hadn't been run in 2 weeks, how did the evaporator get 'frozen' in 5 minutes?

Guy came back the next day, spent 2 minutes in the attic with the AC, comes down says evaporator is leaking refrigerant. Gives me a bill for $184! For a grand total of 10 minutes work with 2 visits. Guy says new evaporators are $2000 and a sales man will call! I noticed he didn't have a refrigerant gas sniffer with him so I asked how do you know that the evaporator is leaking refrigerant?

He said that oil was in the pan, funny, I saw no oil. NOT RECOMMENDED! I should have signed the $184 bill 'Ben Ripped, .because I was! To summarize: I spent $184 for two visits and still my AC doesn't work. Of course they want me to spend another $2000 then it will work just fine.

I'm extremely disappointed in the lack of help received especially since my unit from them is less than 3 years old. Do NOT call them on the weekend and pay the "emergency" on call amount because they don't disclose that if they don't have the part in the truck with them that you've wasted your money. Instead of helping with a solid solution their answer was to pay $250 more to get the "warrantied" part that was needed or "find another company" (from the woman on the phone's mouth).

I should have known the service was going to be bad. That same weekend that I first purchased my home with units installed by them (newly built) we had no hot water (it was WINTER & I had a newborn) they were extremely rude when telling me that no hot water was not an emergency. Don't waste your time or money.

Christianson plumbing came highly recommended by a close friend who is a contractor so I was looking forward to great, honest, friendly work and but unfortunately got just the opposite. Maybe they do great work with large volume clients, but if you have a personal, residential problem go ahead and pass on them. Try O&M plumbing or Blue Dragon instead.

In addition to their cost structure shifting last minute (20 mins before their contract plumber came; from $90/first half hour to $2.25/min after for a water filter install to $200 flat fee), the plumber was unhelpful when we found that our product was a lemon. All this would've left us giving a 3 star experience, but to cap off our experience, when we called to give the gentle nudge/feedback that we were miffed about the last minute cost shift, we were rudely yelled out and addressed in a condescending, unhelpful tone by the operator. You can find much, much better. Hard pass on Christianson HVAC & Plumbing!

I used them a few months ago to replace the indoor unit at a rental home and the install went great. I was very pleased. And I was happy to find a company I could rely on to do a good job. Fast forward to yesterday, I called them to check a Trane unit at another home. The fee to come out was a reasonable $75. The tech came out and found that a mouse had chewed through a wire at the outdoor unit.

They wanted an additional $120 to splice in a new wire and reprogram my thermostat. When I asked why the thermostat would need to be reprogrammed, he stumbled over his explanation, finally saying the error codes needed to be cleared. I know for a fact that you only need to reboot the thermostat via the wall switch to clear the error codes (I was right, btw).

He calls me back and agrees to just change the wire for $80. Fine. It's still expensive, but at least it'll be done. When I checked the job this morning, I could see the old wire leading right up into the unit. I'll edit this if I find a spliced in wire when I check tomorrow morning, but I assume he just used the slack in the wire to reconnect to the control board.

In addition, he broke the plastic housing on top of the condensor in two places, and left the sharp edge of the panel rubbing against the wires going into the unit. See the photos. When I called to complain this morning, the service manager told me it was his honest opinion I had intended all along to find everything wrong I could with the job so that I could get out of paying for it.

At least he agreed to refund the entire amount, but now I have an outdoor condensor that looks broken as I try to sell the house. I have all the calls recorded in case anyone in management at Christianson wants to hear them.
