I finally have my HVAC system replaced.

I initially met with Jack to plan things out. Jack did an excellent job with the proposal and help answers all my questions and concerns from start to finish.

On the day of installing the new system, the team showed up on time and did a very good job of replacing my system. The team consist of Gerson, Jose, and Jose. Similar to Jack, Gerson did an excellent job of explaining everything and address all my questions, and concerns through out the day of the installation.

There are a few minor things that I didn't like with the installation, but that's just nit picking. (1) The new HVAC system didn't perfectly line up with the air return trunk. (2) They kept putting screws wholes into my air return trunk.

Overall, another great experience with AllTech Services. Highly recommend.

This company was a highly pleasant experience to work with from the ladies who answered the phone to the technician (Jack) who came out to my home. The communication with Alltech was clear and the response was always prompt. I had an issue where my heating system was blowing cold air and they quickly scheduled Jack to come out and diagnose the issue. He diagnosed quickly and gave me the estimate, which really was quite fair in comparison to other quotes. They immediately go the part needed and did the repair. Jack was thorough and gave sound advice about efficient use of the system. He was professional and cleaned up the area back to the way it was upon his arrival. Lastly, they worked with me around my schedule, which is very much appreciated! Would not hesitate to call Alltech in the future.

I was a holder of the home care program and I have to say, that instead of getting a preferential treatment, you are falling on a second burner in my opinion. They rescheduled my appointment twice in one day and both times it was some kind of emergency. I feel like once you are a home care customer they don't have to try too hard for the business especially for the semiannual checkups, since they don't charge for them.

Once you get the guys in and working, the service is good and I never had a problem with it. So for that reason the rating is 3 stars instead of 1.

These guys/girls are real professionals. First of all, their communication: they email and text before they come, every single time. They also respond to emails promptly (even on weekends!)

We had a 20 year old AC/Furnace that was not working too well, Stewart came out, on time, diagnosed the issues and explained the problems in detail. There was no scare-tactics, just straightforward technical details what can/can't be done, what is worth it what's not. The conclusion was to replace the system.

Then Jack, the sales manager came, on time, provided multiple quotes, detailed explanations of each possibility, its capabilities, pros and cons. We selected a system, negotiated the price - all of this through email - Jack was impressively responsive.

Then today, Gerson and his team came, on time. They worked all day, did a real professional job - and the new system is up and running like a charm. No mess, no issues. When you look at the system you can just immediately see that it was installed by real pros. At the end, Gerson took 30+ minutes to walk us through every detail, and explain the next steps (follow up visits, warranty, etc.)

This was probably our most impressive contractor-experience during the last 10 years. These guys/girls are good!

I recently moved and had an issue with my HVAC system. It was a more advanced Trane Tam7 that a different HVAC guy could not figure out. AllTech was able to get me in for an appointment within a day and their technician's knew what they were doing. They were on time and provide notice of when they are on the way. I felt the price was fair, will use them again

★★☆☆☆

Very nice and polite. However; overcharged, spilled dirty water all over the carpet, left the cut open drywall size of the large printer box in the downstairs bathroom. Cannot recommend...

My AC failed and was blowing hot air. Based on yelp reviews I decided to call them and have them come to check my AC. They were very polite and professional. Also I received an automatic notification on my phone about tech being on his way. Stewart was very helpful and he was able to fix my AC quick. I would definitely recommend them to everyone and I would choose them again in future for HVAC problems.

We are replacing one AC unit, humidifier, water heater & adding an air purifier. We have used this company in the past to service/diagnose our units & were so impressed we returned to use them for replacement when it was time. Jack Posey was professional and took the time to explain the options we had. We are very happy with everything.

AllTech is good when it comes to service. They came out on a busy Saturday late in the day. Joey was knowledgable. Diagnosed the problem. Helped to implement a temporary fix. Part was ordered and Jack came on Monday at 11 AM to fix it.

Problem is with the fees. Joey said that they charge a flat fee for their work which is an average of the time it takes to get a job done. He said it might take an hour or up to two to make the repair (replace induction motor on carrier heater). When Jack came, he finished the work in about 20 minutes. Which is good. But then the labor charge comes out to somewhere between $1000 and $2000 per hour. Maybe Jack is the best darn tech out there. But even if he took a full hour, I dont think the going rate for HVAC labor is $500/hour.

I messaged to their customer service and they gave standard line 1) OEM part you could not have done it yourself 2) we came on saturday and repaired issue within 72 hours 3) technician was very experienced 4) 1 year warranty.

All that is fine but a) it's not good business to leave a potential repeat customer feeling like they paid 2x or 3x on labor. b) not good to quote 1-2 hours of work and then do the project in 1/4 the time but still charge full amount.

If I had an emergency I might call All tech again but I would definitely get multiple estimates to make sure i'm not getting fleeced.
