BEWARE of Albortz: **Sabotaged my HVAC to Create Repeat Business**…read more If you're in the market for HVAC services, I strongly urge you to steer clear here. Over the course of a couple of years, I've encountered multiple incidents that seem to point to deliberate sabotage of my heating and cooling system. I also have PROOF in my pictures. I'm somewhat handy, and if I was not, I would have been taken advantage of even more. Here's my story: **Incident 1:** It all started when my AC unit broke down during a heatwave. I had a newborn at home, so I needed help fast. Despite being on the pricier side ($500 for the visit), they were the only ones available quickly. The technician "fixed" the issue and tried hard to sell me a brand-new unit--despite the fact that my current one was still functioning. I brushed it off as a sales tactic. However, when the weather turned cold, I realized my **heat wasn't working**. I'm a bit handy, so I took a panel off to inspect the unit, and what do I find? The **gas line had been turned off at the panel**! It's important to note that the heater worked just fine before this service, so the only possible culprit was the technician. Had I not caught this myself, I would have likely been convinced that the entire system needed replacing--costing me even more money. **Incident 2:** Later, I did end up getting a new HVAC system (from a different company). However, my diverters (which control airflow) stopped working, blowing a fuse. Once again, no one else was available, so I had to call Alborz again. I was skeptical after last time, but thought maybe it was possibly an accident... This time, I was on high alert and watched him closely. He fiddled around and had me go check the thermostat downstairs while he "worked on the unit." Reluctantly, I complied. Sure enough, when summer arrived, **the AC stopped working again**. **Proof of Sabotage:** After some investigation, I discovered the technician **deliberately disconnected a wire** in my unit, which is why the AC wasn't working. I have photographic proof showing the disconnected wire and the work area, demonstrating this malicious action. --- **Final Warning:** It's clear to me this company has a pattern of **sabotaging equipment to generate more business**. These aren't simple mistakes; they're calculated actions designed to mislead homeowners into believing their systems need more work or replacement than is necessary. If you're considering hiring them, think twice--you may end up paying more than you bargained for, both in money and frustration.

Called to have a $600 gas stove plumbed in; was told about the $99 charge to come out, but no…read moreadditional information given regarding the cost to install. Nick came out; SUPER professional, courteous and very understanding...the cost to do a 20 minute installation was close to the cost of the appliance, over $500...unacceptable to not even give a range of the cost of the installation forcing you to pay the $99 fee for them to come out and 'give' you the estimate. Strange business practice. Other than an attorney or a well paid surgeon, I'm not sure who else makes over $500 for a half an hour of work. We did have them install, but won't use or recommend them in the future. Too bad because their tech was awesome !!

He gave his honest opinions of what could be replaced and what the rough costs were for each component plus labor. He also explained what he thought was the best option to keep our current system running at it's best, which I chose to do. He re-gassed our unit and added a startup capacitor which seems to have done the trick! The outdoor unit kicks on easily, runs quiet and consistently now. And of course the AC blows ice cold now. He even gave recommendations for future maintenance for not only the AC unit but the boiler as well. I can't recommend Total Comfort Mechanical, and James, enough!

A rather complicated and sad review. I am a senior citizen. My gas heating system needed…read morereplacement after a fire in my furnace. $20,000 and I replaced it. The very next day the second heating system I had in an addition failed. I was distraught!! Net Zero gave me a great quote..several thousands less than other HVAC. What they did not tell me that they were only electric heating contractors. So after paying $12,000.00 for installation I now pay an electric bill of $1000.00 a month in the winter. They walked by a brand new gas system in my home..disengaged a second gas heating 50 feet away and installed a unit that is costing me a thousand dollars a month. Not one of the employees ...installers. or project estimators...addressed what a poor and unkind decision this was. Now I have to redo my heating system...sell my house...unable to retire . Would they do the same to their mothers..grandmothers? This is a sad and sorry company. Yes I know I'm a stupid elderly woman with no recourse from people like this. I just hope this warns others to avoid this snake company.

From the start, he was honest, thorough, and transparent. He took the time to explain everything clearly and never once tried to upsell us on things we didn't need. We decided to replace both our AC system and gas furnace (after the furnace died on the morning of the first blizzard!) with new American Standard units, and Gill gave us a very fair and reasonable price. While Warrior may not have had "7 trucks ready to finish the job in one day" like some of the larger companies promised, Gill and his team focused on doing the work the right way -- with care, professionalism, and attention to detail. What really stood out was the customer service. Gill even helped us install and set up a new smart thermostat I had purchased myself. It's rare these days to find contractors who are both skilled and genuinely trustworthy. We'll absolutely be calling Gill again for any future HVAC needs, and we highly recommend Warrior Heating and Cooling!
