Good afternoon, I contacted three HVAC businesses in the Oakton area after our 1st floor Carrier home air conditioning system went out. I selected the three vendors based on Angie's list and additional reviews and personal long term experience with one of them. Alltech was one of the three. Jack Posey is the sales person who came to our home. He arrived on his scheduled time, called ahead to let us know he was enroute and was a professional and personable representative for Alltech throughout the visit and subsequent discussions. The online evaluations for Alltech are first rate and Jack, if anything, added to that reputation. He was knowledgeable, pleasant, informative and provided all the technical information needed to make an informed decision. His estimate was timely and professional. In this case, our decision was complicated by the competence and professionalism of all three businesses I dealt with and none provided any negative discriminators. Jack worked with us to get his price as competitive as possible. In the end we selected another vendor based on that company's ability to get a little lower during this snapshot in time. Our final decision came down to price and was not based on a value judgement of Alltech or Jack in any way. I will be happy to provide my highest recommendation to both as they pertain to the services I received (Responsiveness, Punctuality, Professionalism). I am confident these characteristics represent the whole of the company business. Respectfully submitted. TDS

Extremely impressed! Best customer service from beginning to end! A pipe burst in my house causing a major flood. Greg arrived quickly and had it fixed in no time. He was very friendly, knowledgeable and made sure the problem was 100% fixed before leaving. They also send you a text message when your technician is in route to let you know their eta, the name and photo of the tech as well as a bio. It made me feel safe having a heads up on who was coming to my home. I will definitely be using AllTech for any future plumbing, HVAC or gas needs!

Initially I wrote a raving review giving All Tech an "A." grade I am now giving All Tech a "B more to C " rating. Unknown to us since (we are not professional heating and AC installers) the original installation on 9-16-16 was not complete. It wasn't until I called the company and spoke to Abe, one of All Tech's managers on or about 5/11/17 that I requested a Loudoun County inspection of our heating and ac unit. All of a sudden All Tech sent a technician out to our home to take a look at the heating and ac unit. From installation on 9-16-16 up until 5/11/17 All Tech had been fully aware and chose to ignore that the air return vent was not installed. The air return vent was then installed on 6-5-17. A larger hole had to be made in our wall to accommodate the installation of the air return vent and a larger grill cover had to be ordered. While everything now seems to have been completed as it should have originally been done on 9-16-16, I am very disappointed in All Tech. For anyone who is having a new furnace and AC installed, insist and request a Loudoun County inspection and gas inspection regardless of what you may be told.

They were high priced. I have been using them for service do far. I’d give the workers an “A”. They cleaned up very well.

Our entire experience from beginning to end with AllTech Services was fantastic. Raymond Sauer, sales person, was very knowledgeable, answered all our questions, explained the Trane system to us without any pressure to purchase, explained what AllTech has to offer and followed up as the system was being installed. We had two other estimates involving Lennox and Goodman systems which did not compare with AllTech's Trane system. The heating and air conditioning systems were installed on September 16, 2016. Installers Nick & Marlin were definitely very knowledgeable, worked constantly until the systems were installed, answered our questions as they worked, and were patient with us as we watched them work. Taking out the old heating system was not an easy task because of the systems location within our home. Also, Nick and Marlin discovered a problem with old ac system's installation (i.e. twist in pipe) which they replaced a portion of that pipe.. We give Nick and Marlin lots of kudos for job well done. We would definitely recommend AllTech Services.

It was a newer system, so nothing expected and not much done with the exception of hooking up some test meters and physical inspection of the system. For that type of job, I think the cost was a little steep when the average price for this type of work by other contractors is reasonably lower.

Full installation of a heat pump system and a mini split system in our 1970s remodeled house with new addition. Complicating matters, we did not have duct system so that was added as well. the heat pump system was on the upper floor and the mini split for the bottom floor. We also have a wood stove and Abe designed the system to take advantage of the wood stove's output to circulate air through the first floor. The design was well done. We spoke with many companies for this as we were doing the addition ourselves. Abe was the most knowledgeable as well as the most cost effective. He knew these systems inside and out and selected the best approach to retrofit our home. The fujitsu system selected for the moni split far exceeded expectations. I m familiar with Mr Slim's but on Abe's recommendation for cost savings and performace, he was right on This occurred one year ago. We could not be happier with the outcome. Abe's installation team was very professional. Out of all the contractors on our addition build, Abe's crew was by far liked the best by my wife who was here all day during the build.

I contacted Alltech by e-mail and requested a quote for a new water heater. Abe responded quickly and had a quote to me shortly thereafter. The water heater was installed the next day without issue. Another great experience with All Tech.
