HVAC reviews in St. Louis, Missouri

Believe all of the one-star reviews you read!!!

This company was recommended by my buyer's home warranty company, who will hopefully never use them again. We were told that we needed to have our blower replaced in our heater due to faulty venting. Thankfully we did not trust their opinion. We got another opinion and found out that the blower was working perfectly fine, the venting is perfectly fine. It was a relay. It was fixed at a fraction of the cost. The blower is working perfectly fine right now and we finally have heat, no thanks to 1 source.

I hear of shady businesses or inept repairman, but this is ridiculous. I really didn't believe that people were really like this. How can someone say that the blower is broken when the blower is working perfectly fine right now. They're either inept or they're lying. Bottom line, I would never recommend this company. The guy they sent out did not know what he was doing or he was falsely raising the price. Either way... big mistake.

Very unprofessional! They called to set an appointment for my furnace but never set the appointment. The lady stated that she would give me a call back but never did. When I call them back they were close on a Friday. It's been almost week no words. This is a vendor from my home warranty plan. I'm pissed because I have small children and we have freezing in our house.

Earlier this year (June 2022) we were assigned 1Source as our technicians to address our cooling issues. 1Source was actually the 2nd company sent to us by our warranty company. They are absolutely phenomenal.
1. They did a full troubleshooting of our cooling system before replacing. We got a new A/C unit. When we still had issues with cooling, Chris (The owner & Technician), was able to assess that the issue was then the furnace.
2. Chris came back with a Partner (didn't catch his name) and they quickly installed a new furnace and return vents...all while educating me on different techniques and reasons for their need to be done.
3. Winter weather came, and we started having issues with thermostat not reaching target temp. We reached out to the warranty company and they sent us someone else. "Someone else" wanted to install a flue going outside the basement wall in order to get more "airflow/pressure" for the furnace via a code that the device was giving out. I called 1Source because I just knew 400 dollars for another hole in my house was not the answer. Chris showed up and immediately began do awesome troubleshooting. He agreed with the code but knew that the issue was more internal dealing water flow/air flow. He came up with a plan to install a piece that would allow the water to drain/condensate more efficiently. This fix was only 45 extra bucks.
4. During the periods leading up to get the repairs done and settling dates/times Keisha and Chris were by far the most helpful, flexible and honest people to work with. My family truly appreciates the patience and professionality that 1Source gives to it's customers.
5. Chris I hope you see this, and you know that as happy I am to see you, I hope to not see you until its maintenance time!

Chris came and fixed our A/C issue then suggested how to keep our aging system going. I had had another company tell me I needed to replace the whole unit and it was leaking refrigerant. He tightened a valve and said it was all good. 1 Source's price for topping up the refrigerant was less than half what the other company was offering. I would highly recommend him and this company to do all your HVAC work. They are competent and fair.

Had a home warranty issue and 1 Source came out assessed the issue. Completed the work and there was a slight drip after the repairs. Today a tech came out and fixed the drip. With the quick fix my prior 4.5 stars is now a 5 star review!

I really do appreciate the front end dispatcher (Keisha I hope that’s how she spells it), Chris a tech who has been out a few times over the years as well as Van and Marquis (I hope that’s how he spells his name) the last two techs who came out recently.

Thank you 1 Source.

I gave 1 star for the technician. Because he was nice. If I
could have put 0, I definitely would have. This company was sent to service my air conditioning system by my "scam warranty company". I waited from Monday, June 24th until the evening of Friday, June 28th for a diagnosis of the problem. They put in a diagnosis of "not normal wear and tear " on a 43 year old unit.😳 I was blown away. I then spoke with one of their "receptionist" who told me that, "the home warranty asks for that so they can deny my claim". Which is fine, I'll handle that separately. But I ASKED for an estimate for repair of my condeser and recoil, I believe that is what it's called, in which she said that I would have one in the next 15 minutes to an hour. That was Saturday, June 29th it is now Wednesday, July 3rd. I have since had a reputable company Academy Air/Morisson Heating and Cooling come to my home on Tuesday, July 2nd and install an entirely NEW air conditioning system in my home. I don't mind spending the money, especially with my people. But you have to be more professional and about the business. This is a good example of being too "hood" and "hip" to handle business. I don't recommend this company, but to each his own. My experience was not good. And I STILL have NOT received any responses from them.

Great experience. My AC went out 3 days before I had an out of the country vacation planned. When i called they set up an appointment the next day. Technician came out early and had to battle the rain but still managed to replace a part. Was extremely nice and helpful.

Needs a zero star button. This company is unprofessional, does hold true to said obligations and is uneducated. This company replaced my ac unit, the ac starts randomly shutting off. I had a different company to come service the ac. The company stated the ac unit is too big for my current furnace so my Home warranty hooked me back up with 1source. 1 source says that issue is impossible (completely not accurate) 1 source was also aware of all said details from the previous tech before they arrived and refuses to look into the issue because now it’s now a furnace issue. That was obvious and this company caused the issue yet refuses to take ownership. This company also came out look at my system and said nothing was wrong give us a call once it shuts off again so we can grab the error code from the FURNACE, I did that and the tech never showed back up. 3weeks later the ac is completely down and the tech literally shows up says I have a furnace issues and that I need pay the fee and r/s. I wouldn’t recommend doing business here. Now I have to redetail all these events to the the home warranty company and previous techs to help hold this company accountable.

1 Source Heating and Cooling LLC delivered excellent customer service from the initial phone conversation to resolving the issue, which exceeded my expectations. I missed the technician on the first attempt because I had to leave the house during the service window for a family matter. They called to let me know they’d need to reschedule, but were gracious enough not to charge additional fees, which is their policy. The technician came out the very next day, assessed the problem, and found a wiring issue that needed to be addressed. He explained that he’d have to send in a request for approval before they could proceed, and once approved, they’d be back. At that point, I assumed I’d have to wait about a week for the approval and then a reschedule, which wasn't that big of a deal because we now knew what needed to be fixed and knew that it could be fixed, but that evening, our other air unit went out. The other air unit was helping to cool off the portion of the house where the original broken air unit wasn't, so it was unbearably hot in the house. I wasn't at the house the next morning but when I got back, I realized that I didn't call them to let them know about the 2nd air unit. At 1pm, I called to let them know, but before I could get anything out, the rep told me that the original repair had been approved and they’d be back the next day. I was surprised at how fast that got approved and how fast they could come back, but I also needed to tell her that now both units were out. She was extremely empathetic and understood immediately, and said she’d check if the technician could come that day instead of the next and promised to call back with an update. An hour passed and I hadn't gotten a call back so i figured that the tech didn't have the capacity, and she'd call back soon....but then I heard I knock on my door and it was Chris the technician! Even with a packed schedule, he was able to fit our air issues in his schedule. I’m forever grateful for their kindness, communication, and willingness to go above and beyond. I would absolutely recommend them to anyone needing HVAC service.

I've been referring and doing business with company even when they were under a different name, however the same great quality of service which is second to none. The repair technician was Johnny Luv and I HIGHLY RECOMMEND him for your service and install needs. In conversation with Johnny Luv, he informed me that his prior experience was with SPIRE GAS Company.

I was sent HVAC Technician Steve W. He was courteous, patient, analytical, used his common sense, professional skills, and repaired my HVAC in a timely manner. This is after two other companies told me my system needed replaced. I think I shook his hand three time before he left.

The technicians,Jason and Matt were very professional and completed the 2 AC/Heater replacements well ahead of schedule. They arrived when they said they would and left the areas spotless when they were done. A great experience from proposal through installation. I will definitely recommend your company in the future!

Xcell Williams Heating and Cooling did an excellent job.

We had been without air conditioning for 3-4 weeks waiting for another company to repair our HVAC. I called Xcell Williams Heating and Cooling and they sent Casey out the next day. Casey came to examine our system and was able to have workers come out to fix our problem the next day. We are so happy we chose them and that we have a working Air Conditioner!

This company was great with working with me on getting my air back working sense i was past customer with them. They did a fantatic job with my furnace and my AC unit. I will recommend this company with anybody. Shot out to Sara you are a wonderful representative for Xcell Williams . you went above and beyond on my behave. Thank you

i’ve worked with Xcell-Williams for both my office and residential HVAC needs. They have proven to be very trustworthy, efficient and helpful in all aspects. I would never hesitate calling them for any means you have.

I had two furnaces and ac units at different locations installed by this company. I had prompt and very professional installations. I even had another company inspect after the first installation and was told it was a very clean and professional job. I would recommend this company for dependability, great customer service, knowledge of equipment and great men who install and represent this company. It has been a family owned and operated business from day one which accounts for that personal care from beginning phone call to the end of the transaction.

I needed a new furnace for one of my rental properties. Xcell Williams Heating Co. came out and looked at it. They offered to repair the furnace, but since the furnace was 17 years old, they gave me a good deal on a new one. Came out an installed it the next day, The installers where organized and knowledgeable. Good service great price! I would recommend this company. Bill Lenich

The team at Xcell Williams has completed large and small jobs for us at a few properties we own. They have not only done quality work, they have acted as advisors and educators with us as we make decisions. We can always trust that they have our best interest in mind!

I was getting frustrated in getting information from a number of plumbing companies regarding changing out my home's water heater. I was referred to Xcell Williams Heating & Cooling and spoke with Casey H., who got me pricing, installation timing and made sure I was putting in the right size water heater for my home. The process was effortless on my part, Sara (the Operations Manager) and Casey coordinated everything and the installation crew showed up on time and did a great job of replacing the water heater. The water heater works great, and, the installation job is very professional. I know water heater replacement isn't something they advertise, but, they do a great job. Thank you.

Called Xcell Williams when found out original installers of my air conditioning (in the attic) and my gas boiler (boiler) no longer service either. Technician was very knowledgeable and patient as he explained how this “boiler thing” works and showed me how to do things myself as to seasonal shut down and start up of the system and radiators. I had some repair work to be done, as 25 year old valves were starting to fail, and he advised me how to save money by doing my own draining and filling of the system, and quick, temporary fixes to maintain heat until he was scheduled to be there. (Moved to a 100 year old home, and am familiar with only electric heat pumps). I had the air conditioner serviced 2 years ago and that technician was also friendly and knowledgeable. Office staff is also a pleasure to speak with. I highly recommend this company and am thankful that, as they seem to be one of the only ones who will do the work I need, are as great as they are.

In 2019, when I was in the market for a new HVAC system, my mother recommended Xcell Williams Heating and Cooling. During the research process, I met with at least ten HVAC contractors and/or businesses. Xcell clearly stood out from the rest. The installers were knowledgeable, considerate, and did excellent work. Customer service was outstanding; pricing was fair, and the purchase transaction was flawless.

Since then, there has been a change in ownership, and from my perspective, the transition has been seamless- with the exact same excellent customer service, value, and experienced, respectful technicians.

Xcell conducted my Spring check-up today, and uncovered an issue. Still under warranty, Xcell resolved the issue, on-site. Casey, Xcell technician, was timely, efficient, professional, and courteous. Casey, Sara, and, perhaps, the owner, took great care of me.

I highly recommend Xcell Williams.
