Recommended Customer Reviews
I just called them for an estimate to have my Heater / AC units replaced. The woman on the phone said they would have to send someone out for an estimate, understandable. She said they only perform these estimates in the middle of weekdays .. when I'm at work. I asked if there might be any earlier times over the next two weeks, or the slight chance that they have time tomorrow. She then quickly replied ""Tomorrow if a Federal Holiday"" .. yup, I work for the government .. didn't know they did too. The other two AC shops were able to schedule someone for this Friday and also made time available on weekday mornings. So my only assumption is that AllTech has plenty of business and does not really try for more. They should have at least tried to make some additional times available. Oh well .. get a better receptionist.
They came out for a quote and were right on time. Reasonable prices, friendly service. When they came to do the work they were again on time, curious, cleaned up well and had creative ideas for minimizing damage to area to access tub plumbing. Greg explained everything to me thoroughly and did great work.
I would definitely use them again.
Lynn L.My A/C condensation unit was clogged with debris causing water damage in my basement. AllTech came out on the same day I called to repair. I was so relieved. I will certainly use them again likely in the fall to service heating system.
Yesterday afternoon the A/C unit at my condo stopped producing cold air; however, the fan was still functioning properly. After having a similar issue in the past, my wife and I turned the unit off overnight to troubleshoot. When we woke up this morning we turned the unit on but it was still not producing cold air. I called my father-in-law, who spent his entire career in HVAC and he recommended having someone come out to (possibly) refill the refrigerant.
After reading mostly positive Yelp reviews, I called Alltech and stayed home from work to wait for the technician. I was pleased with the same day service, and he arrived within the window I was given by the scheduling office.
The technician was polite but not overly friendly, and seemed somewhat disinterested when I mentioned the initial troubleshooting steps we'd taken. In addition, he seemed unfamiliar with the make/model of our A/C unit and referred to the diagrams on the front of the unit several times for assistance.
After completing his troubleshooting steps, which he did not thoroughly explain, he concluded we need a new compressor for the unit, at an estimated cost of $2000. When I asked him whether he'd located and cleaned the unit's condenser coil, which can cause the elevated pressure and amperage values he provided to me, he said the coil was not easily accessible on the unit and again claimed the cause of the issue was the compressor. He reassembled the unit and told me to try to stay cool until the compressor could be ordered and replaced.
Once he left, I spoke with my father-in-law and provided him the information I received. Based on his feedback, I called for a second opinion. The individual I spoke with via phone was much more helpful and came to the same conclusion as my father-in-law, that the condenser coil most likely needs cleaning, which is a $400 service. He went on to explain that cleaning the coil is important even if the compressor does need replacement, because an unclean coil would only ruin a new compressor. He was honest, thorough, and even asked me to text him pictures of the unit, on his day off!
Needless to say, I will be using the other company and their technician moving forward and do not recommend Alltech based on this initial experience.
As a final note, when I looked at the reassembled unit, I found screws and parts that the technician removed that were not reassembled with the unit, which is concerning. After paying a $95 service fee, I expect my unit to be in the same condition in which it was found.
Note: The woman from the Alltech scheduling office called to follow up on the compressor quote and seemed receptive to my feedback. She said a supervisor will call me tomorrow. That said, I plan to update this review if warranted.
Update: On Tuesday, one of the managers from Alltech, Abe, called for a follow up based on my negative feedback from the service appointment Monday. He was very helpful and even refunded the $95 service fee due to my lack of satisfaction. Then he offered to come and inspect our unit himself, at no charge.
He came out this morning and was extremely professional and thorough. He explained every diagnostic step he was taking and made every attempt to repair our unit. He wasn't able to access the necessary compartment, but provided an estimate for removing the unit for cleaning/servicing.
Based on my experience with Abe, this is clearly a company that, at the leadership level, values their reputation among their clients.
All that said, while I already sought a second opinion from another firm, I would consider using Alltech again in the future and would highly recommend Abe, personally. The only reason I did not update the review to five stars was the initial experience with the previous technician.
Janine S.We hired AllTech for our gas conversion project last fall and we were very satisfied with every part of the project. AllTech came out to our house several times to adjust the estimate based on our continually changing ideas for the project- no complaints from them and very easy scheduling. They gave us the best price (and we certainly shopped around. I got 7 estimates from other companies) and were the best to work with. They responded to e-mails quickly and answered all of my questions. They were easy to reach by phone and always returned calls if not.
Although I was not home for the actual work, my father was and he couldn't have been more pleased. Everything was explained along the way and the men made sure to clean up after themselves. We had lines run through our home for a gas fireplace, range, dryer, and new tankless hot water heater. While several other contractors refused to or said parts of the project just weren't possible (getting the hot water heater where we wanted it, hiding the gas lines), AllTech said no problem and did everything exactly how we wanted it, and kept it to code.
Overall a very honest, decent, hard-working company that will work with you to get you exactly what you want a need. We will definitely call them again in the future!
I submitted an online scheduling request this morning for repair on two toilets. The plumber was here and fixed both toilets in less than 2 hours for less than $150. This was not a complicated job, but it was handled quickly and professionally by a very courteous technician. I have additional plumbing projects that I need to complete and will not hesitate to call them back for service.
Tom S.As you'd expect my hot water heater died on a Saturday. I called AllTech on Monday morning and spoke with Abe who took the time and answered all the questions I had about the service call as well as the hot water heater model they use, which is manufactured in the US. He provided an estimate, but recommended I have a service tech come by and provide a written estimate with the understanding that if I chose to accept the estimate they would perform the work at that time.
He advised me that they would arrive around noon, but would give me a 30 minute call prior to arrival. At 11:30, I received a call from the office that the service tech was running late due to another call and would arrive later than originally planned. Not an issue, but I appreciated the call.
As agreed, 30 minutes prior to their arrival I received a call. Upon arrival, Greg and Michael introduced themselves and I showed them the the hot water heater and explained what had happened over the weekend. Greg, was very helpful and explained that my current water heater was the original and just over 20 years old, so I was not too upset that it finally died.
He took a few minutes to put together the estimate and it was right in line with what Abe had provided earlier. I accepted the price and within a couple hours, the new water heater was installed, the old one removed and the entire area was cleaned as if nothing had happened.
The entire experience was as pleasant as it can be when you have to spend money unexpectedly and will definitely use AllTech in the future for any plumbing or HVAC issues.
Teresa P.Our water heaters (gas & electric) die last week. After reading the yelp reviews we called AllTech Services.
Pros:
Same day service
Very polite
Replaced gas heater next day
Clean up after themselves
Locked up after they left
Cons:
The helper asked to use our broom to clean up. Haven't seen my broom since. :-(
Several miscommunications:
-We said a 10am appointment won't work because we had another appointment at that time we could not change but they could be here while we were gone
-We wanted 8:30am - they arrived at 7:30am so the could finish the job by 10a.m.
-At 10:10 I stated we need to leave. I was told we are wrapping up now.
-At 10:20 we left saying we would be back shortly. No one was here when I returned the invoice was on the kitchen counter.
UPDATE: We have had AllTech back to our home 3 times since the initial review. They remounted a kitchen sink, fixed 2 toilets and the master shut off valve. They are always on time (or early), polite, conscientious, and ALWAYS clean up after themselves. They even offered to replace a broom that went missing. We are happy customers.
Anngi T.I was really impressed with this company. I came to yelp looking for a place to fix my furnace that conked out. I chose AllTech because of the high rating and good reviews. My experience was also excellent. I called on wednesday before christmas and they sent a technician out a few hours later! Ed was my tech and he was excellent, very professional and knowledgable because he knew right away what the problem was. (And cute, so that was an added bonus) ;-)
He fixed it in no time and also did diagnostic and cleaning so it's good to go. I would highly recommend based on my experience.
This company is professional, on time and estimate was fairly priced. We called them based on the yelp reviews and so happy I did. My water heater started leaking and we needed to get it replaced quickly. A tech, Joe came out and diagnosed the issue.
After did my part and called other companies for estimates. All of the other plumbers were late, unprofessional and quoted me 3x as much.
It is rare these days to find a professional and trustworthy company!!!!! This place is awesome!
