Landmark Air Systems, Inc.

They installed heating and AC for me.
They made several mistakes on the installation of the boiler. There were missing check valves, missing drain valves, missing isolation valves, installed the wrong expansion tank, they put the make-up water line in the wrong place, the pump was in the wrong place, the domestic hot water intake was connected to the boiler make-up water line when it should not be, etc.
I have contacted them by phone, email and text and they will not return any attempted contact to try to resolve the issues.

Do not use this company under any circumstance. They installed an hvac unit in my home through a general contractor so I did not directly hire them.

The unit is less than two years old and has had multiple cooling and heating issues and recently caused two leaks this summer. I have called them several times over the past 2 days with no response.

I had a more reputable company inspect the work and they said it looked unprofessional to them. Avoid landmark.

Never hire these guys! Sadly, We learned that you get what you pay for. They were the cheapest and we went with them. We started to have problems in the second year but when I called them they never responded. Then this year, the problems escalated and we called another company since Landmark once again didn't respond. Our walls were bubbling from moisture and the new company found that landmark had cut corners and removed the installation around the ducts to snake it through the walls. Now we are having to open the walls to correct the problem. We have to deal with this issue immediately since we could be dealing with mold. Please be smarter than we were.

Landmark installed an entire heating and air conditioning system in our house three years ago. It has never run correctly in the summer - on an 80 degree day, we cannot cool the house below 76 degrees. This despite a contract that promised 70 degrees inside on a 90 degree outside temp. Because we wanted to do the decent thing, we paid them in full, with assurances that they would fix the system. They have not, and they no longer answer our calls. The AC is unworkably underpowered. Yes, our house is a challenge, with lots of windows, but nothing different than when Tony specked it out, and under serviced our needs - by a long shot. This is a terrible company. They may give you a low ball estimate - it's because they do sub-standard work.

Top-notch, first-class company. Showed up on time everyday, communicated before and after, and did a quick, effective job in my freezing cold apartment. I would highly recommend Landmark for any work in your home.

Pretty good great tem work they are a real professional and responsible people they can work on many different brands systems boilers heat pumps and regular ac systems

Does not register apprentices per DCA Ct as required by law. Regularly and matter of factly violates EPA regulations.

I've had a leak in my system - I've been calling them for three days to request service - I keep getting sent to voicemail yet NO ONE HAS RETURNED MY MESSAGES.

Great Company.
