Summary:
Their installers lacked proper training, resulting in various problems with the AC units over the years, including falling units, condensation issues, and extensive wall damage. Accuserv only provided temporary fixes instead of addressing the root cause. Despite having warranty, they refuse to service properly and expect me to bear future expenses. I chose Accuserv based on good reviews and warranty, but their professionalism didn't match their 5 star façade. Buyer beware!
Details:
Accuserv informed me via email, they are dropping me as a client due to my "unrealistic expectations". Accuserv installed a brand new AC/HVAC 4 years ago. Unfortunately the installers assigned to my project lacked proper training and expertise.
From the onset, there were problems with the install and performance of the ACs. Issues included AC head unit falling off the wall, improper insulation causing condensation, no peat traps installed, no heat in the winters, multiple head units leaking water that resulted in extensive wall damage.
On one occasion, they dislodged a drain tube behind the wall that resulted in extensive water damage, where I had to replace drywall, insulation and paint. I have incurred thousands of dollars in expenses as a result of Accuservs problematic install. Over the years, they have tried to mitigate these problems with temporary fixes, always coming for a service call, yet failing to address the root cause of the issue - their incompetent installation behind the walls! I have asked them to reinstall it properly but they refuse and opted for quick fixes instead, until today.
I followed Accuserv's maintenance schedule recommendation since the onset. Shortly after the last cleaning, the AC unit heads were again leaking greasy grime and condensation was dripping down the grills. A service call was promptly followed by an email from Accuserv that states the following:
"It is with regret that we have decided to discontinue our services due to the difficulties we have encountered in what we deem are unrealistic expectations. We understand that the system we installed is still under warranty, and we want to make sure you know that we take full responsibility for any legitimate issues that may arise during this period. To ensure that any potential issues are resolved, we propose the following course of action: if you encounter a problem with the system, we ask that you engage a third-party technician to assess the situation and determine the cause. If the third-party technician concludes that the problem is related to our installation, we would be open to discussing the possibility of reimbursing you for the expenses incurred in having the other technician fix the issue. "
According to Accuserv, having a problem free installation is an unrealistic expectation that installations should not damage my property and I have to incur expenses for any future issues with the AC, despite the fact that I have an 8 year warranty remaining.
I chose Accuserv due to 5 star reviews and warranty. If I was going to spend tens of thousands of dollars on a AC/HVAC install, I wanted someone reliable, and knowledgeable. A company that takes responsibility and stands by their work. The 12 year no lemon warranty seemed to provide the security I needed to trust the installation to Accuserv. I did not want to cut corners and pay the price later. Yet, despite all this, I have been paying the price dearly by choosing this company. Accuserv presents a pristine professional façade and I was fooled. Buyer Beware. Look at the pictures, not at the stars !!!

Called to get help on a very hot day. They insisted it was a control panel needed. I accepted the diagnostic. The install happened quickly and a deposit was required. After the install within 2 weeks the furnace shut down completely. I called them and they said I need a new furnace. I asked other companies to look at our situation. Yes a new furnace was required from the beginning not a 750.00 control panel.
Accuserve was not truthful. The owner called and I was refunded in full.. I appreciate the attention to my situation.

Called Accu Serv when my water heater stopped working. they sent a tech quickly to run a diagnostic on my tankless and ordered the part that it needed to be fixed. The part took awhile but i don't think that was really in their control. Communication was great and timely. would recommend.

first they sell us on a particular model central air unit, then a heat wave hits and they tell us they can't get it for another 2 weeks and might not be able to install it for another 3-4 weeks. so they upsell us on a more expensive model that they have in stock. then they come to the house to do the install and don't use the existing entry points into the house and make new ones and charge us an extra $500 to do so. not only was this work of poor quality and now we're going to have to pay extra to make it look nicer, but they didn't clean up the old lines. then when I try to pay off the bill they said they were going to charge me an extra 2% processing fee because I wanted to use my credit card and pay it off in a single transaction instead of doing multiple e-transfers.

Accuserv installed my furnace and water heater and comes for yearly maintenance. After 6 years our furnace had problems and they were there promptly and stayed until the issue was resolved even working after their shift was over to install the needed part on a Friday night! Daniel’s commitment and congenial nature, not to mention his skill at accurately diagnosisIng the problem and fixing it was exemplary . Thank you Accuserv.

For the above service, I had estimates from several company. I chose AccuServ for a few reasons;

1) They have the best blog talking about efficiency of water heater tank (gas vs electric) - very easy to read and understand for a layperson like me.
2) They sent a consultant almost immediately after a first call
3) Vlad, the consultant, was very friendly and answered all of my stupid questions without rolling his eyes.
4) The price (including minor construction) was very competitive comparing others (one company estimated $6000 for the same job...)

The office was very accessible and easy to work with. 2 technicians who came on time, comcored all challenges we have in our small basement, cleaned up everything after their work. The tank works flawlessly thus far and no longer running out hot water during showers.

Only thing (not complain though) is I wish I could use my credit card without 2% charge (and their automated invoice system was a bit annoying) but I love my new tank and nothing to take any stars away. Thank you!

Our furnace broke down at the worst possible time, on Christmas day. Accu Serv were able to come within couple hours after I made a call. After weighting our options, we’ve decided to replace the old furnace with new one. Accu Serv were able to schedule the installation for very next day.
I’ve found them professional and friendly to deal with. They were very responsive, their team showed up on time and provided quick and clean installation.

When my A/C unit stopped working, AccuServ was able to get a technician onsite next day. Charlie arrived on time and efficiently fixed the issue and was very transparent about costs. He not only addressed the problem but cleaned the unit and explained what I needed to do to keep it running better. My entire house now feels much cooler.
I find AccuServ to always be professional and reliable.

My A/C unit faltered right at the peak of the heat wave. Charlie the technician diagnosed the problem and fixed the unit, all within my budget. Special thanks to Charlie and AccuServ on a job well done and for restoring peace and cool air to my home!

I would definitely recommend this service and would call ACCUSERVE again if needed. The technician came and detected the issue with our AC right away and dealt with the problem efficiently. He was very thorough with explaining what was wrong with with our AC and gave us complete honesty. It ended up being a big job which I knew would’ve been costly but it was very well worth it! Our AC now runs smoothly and to it’s full potential during this very hot weather!
