HVAC reviews in Upper Marlboro, Maryland

The technician did a great job. Very knowledgeable and polite.

The technician was knowledgeable and was showing me videos and pictures of what he found of my HVAC unit. It could’ve been the cause of why my AC wasn’t working. The only thing was, he forgot some things at the office. I had to go all the way back to get it, which I had to wait additional hour for him to return.

Horrible. All they want to do is sell you a new unit. First came out and said it was leaking and should probably buy a new unit and wanted to tell me about the financing regarding a new one. Home Warranty company didn’t agree and told them to fix it. It was blowing hard but not cold. They took it for 3 weeks to fix and I had to call to get an update before they said it was ready and charged me over $1,000. Put it back in, and they said it worked like it was supposed to. But it did not blow hard anymore but was cold for their standards. It didn’t cool the area needing cooled and would run 24/7 and never get near the set temp. Called them back out 3 more times and they messed with it. More than once, they missed their repair hours “window” by over an hour and never called until they were 5 min away after being over an hour late. Third time they finally ran test and realized there was still a leak that wasn’t fixed. They took it back for 2 weeks. I called at 2 weeks and then they said it was ready. They brought it back and put it in. Didn’t even want to test it or turn it on before leaving. Still didn’t work right. Called them back out and they keep saying it’s blowing cold enough per their standards, mind you they were standing in the hot area of the house feeling that it’s clearly not working correctly and it’s been running all day. I once again mentioned the fan not working hard enough and reminded them it was blowing hard and correct before they took it apart, it just wasn’t cold. Now it’s cold but not hard enough to cool the area. Was then told that “unfortunately, because it’s old, sometimes when it gets put back together it won’t work as well as it did before and the boss won’t approve a fan replacement on it because if it’s age” was then again talked about getting a new unit and he didn’t even go up and look at the inside unit again to make sure they didn’t miss ANOTHER leak or didn’t reinstall it correctly. Then a few days later I get leaking coming from my ceiling where the unit is. I go up there and there are screws missing in unit and parts not put on and trash everywhere. Water had leaked out everywhere and I had to use a shop vac to suck it all up so my ceiling didn’t fall through. Called another company who came and saw that United way over charged it per the specs of the actual unit. American Home Shield needs to cut this company off their list. Do yourself a favor and call a different company.

Technician Jose and Supervisor Giovanni responded to an American Home Shield home warranty service request for drainage issues. Jose conducted a standard snaking service of the basement clean out; however, that approached did not remove the clog. He then called the supervisor for a camera inspection, which revealed the severely deteriorated state of the main sewer line pipes. I am a recent homeowner who closed on the property two months prior. Obviously, the seller had intentional failed to disclose $10 - $15K in plumbing repairs that has now rendered the property unlivable. I was devastated.

Jose and Giovanni did not pack up their equipment and wish me luck, instead they went above and beyond to help me understand my options to resolve the plumbing. They walked me through the property sharing their expertise to understand the work that was previously done. Then other options were considered to ensure that snaking was not a viable option before providing an estimate for hydrojet. Giovanni explained next steps after clearing the clog, which is replacement of the main sewer lines. He also informed me of WSSC options for learning more about the plumbing work and potential programs. A nightmare discovery had a bit of silver lining thanks to Giovanni and Jose.

Jose returned later with parts to complete pump repairs. I learned that after the visit, Giovanni and Jose took the time to contact WSSC for a dye test to aid in diagnosing the sewer blockage. Those two were absolutely remarkable and I deeply grateful that is who responded to a seemingly routine AHS service request.

The tech was very nice, respectful and punctual… Very knowledgeable about what i needed and made sure i understood issues that may occur in the future for my unit… although while he cleaned my unit the igniter broke, he got a new one ordered and replaced within a few days at no cost to me.
Thank you..

I contacted United Air Temp on a Sunday evening after noticing my AC wasn’t cooling my home. They reached out to a technician in the area who was at my home in less than an hour. I was very impressed & grateful I didn’t have to take a day off of work the next day to wait for a technician.

Roger was very professional and thorough throughout my entire service. He took the time to show me what areas needed attention. Then, he triple-checked to ensure my system was running at peak efficiency. Thank you, United Air Temp, and American Home Shield!

Absolutely worst company to deal with. It took then 5 visits and 2 months to diagnose a leak. My house would not warm up and they kept misdiagnosing the problem. Their misdiagnosis caused my emergency heat to over work and tripled my electric bill. When I called for a resolution they didn't respond . I had to call several times for them to tell me basically it isn't their problem. I would never reccomend this company. They are incompetent and not accountable.

Absolutely the worst customer service experience I've ever had — with one notable exception.

I scheduled a routine spring checkup with United Air Temp. My unit was working perfectly fine before the technicians arrived around 10:00 a.m. They disassembled the system, told me it needed cleaning and deodorizing (which I agreed to), and then things went downhill fast.

By 1:30 p.m., I was told a bolt was missing and another tech would bring it around 4:00 p.m. That technician showed up, sat in my driveway, and when I asked him for an update, he shrugged and said, “I don’t know, I just came to help.” I called the office multiple times and was passed around from person to person with no answers. At one point, a rep even asked me if the techs “spoke English” – which was both offensive and completely inappropriate.

The original technician finally returned after 4:30 p.m. with no resolution. A manager eventually told me someone would come back the next day to reassemble the unit. So a simple cleaning took over 6 hours, with no communication, no accountability, and no professionalism.

The one bright spot: the manager did come out the following morning, resolved the issue quickly, and offered sincere apologies. He was professional and courteous, which I appreciated.

If I can offer one recommendation to United Air Temp: consider providing more thorough training to your technicians and avoid assigning titles or responsibilities to individuals who clearly are not ready for them. This was not a one-time fluke — this is a pattern of poor service and poor training on your organization.

Very fast and professional. Would recommend

Quick & efficient. Explained and fixed the issue with my new thermostat.

They said they'd look at the job but never came out and didn't call.
Totally unprofessional.
If you're too busy just say so!

Thank you, Zack! for taking the time to explain what was wrong with my AC unit. Great same day service!

They were responsive, attentive, punctual and clean. Thank you for servicing our A/C units!

Great response time and very professional. Assesssed my issue and provided a great price for the repair and completed the repair the next day.

I have been using Zack HVAC for more than five years now and have always done an outstanding job.

The professionalism is outstanding as well as the service. Answered questions in detail. I will be using them again to replace my hot water heater. Thank you!

Zack HVAC services has been great to us and very accommodating to the different challenges we have had I’ve the last two years!!! Would absolutely recommend!!

Had a emergency issue with my HVAC, Zack provided excellent service, was very informative of the potential causes. I will absolutely use him moving forward with my HVAC needs.

Zack is the man! He was timely and able to fully diagnose and repair my unit quickly. He was informative, professional, and trustworthy. Highly recommend his services!

I've been working with Zack for several years now, and it is always a pleasure doing business with his company. He is responsive to every request, and goes the extra mile with customer service. Last spring, he replaced the AC system on the roof of my row home, including sourcing the crane to lift everything up and down and coordinating some roof maintenance that was required at the same time. The whole service was performed professionally, and I especially appreciate the clarity of communication and the time he takes to answer my questions.
