Donmar Heating, Cooling & Plumbing

Their service is super pricy. They have groupon deals that you pay minimum amount for them to come and inspect your A/C and say it has several problems. But they will charge you crazy for doing the suggested repairs. I cannot believe for 15 mins worth of work with minimal tools required, they made me pay $320. I will never ever go back to them.

This company installed a new HVAC system in our home and we also used them to install new condenser for
a rental property we have in Ashburn.
The technicians that were deployed were knowledgeable and the service they performed have always exceeded my expectations.

I had a routine AC maintenance appointment which uncovered the need to replace my capacitor and cleaning of the compressor unit. I found Rapheal P. from Donmar to be easy to work with, the prices were reasonable, and he didn't try to pressure me into buying extra services. The capacitor had a 1 year warranty which was great because a few weeks later, a field mouse somehow found its way into the housing and shorted the darn thing, so it had to be replaced. I would definitely recommend Donmar/ Raphael!

Rest in peace little field mouse.

I bought a groupon voucher for an AC unit inspection from Donmar. The technician who did the inspection seemed professional and told me my unit was in excellent condition. That was a few weeks ago. However the unit have stopped blowing cool air since yesterday. I called Donmar today and was told a technician would contact me shortly. I have not heard from them since then. I am puzzled how a ""perfect"" machine would stop working properly only a few weeks after the inspection.

I called hoping for same day service. They were able to arrive service within the hour. The technician arrived on time and called me upon arrival. He worked on the system for more than an hour and told me what the problem was. He gave me a written report about the problematic HVAC system. I received timely and relevant information. I would recommend their services to anyone.

I finally decided to replace my 17 year old upstairs heat pump / air handler, which has required expensive repairs the past several years. Don Wills, President of Donmar, came to my home to provide a quote. Don is extremely knowledgeable, answered all my questions, and provided a competitive quote with several choices that allowed me to trade off cost versus size and efficiency. He also offered a discount if I replaced my downstairs A/C / furnace at the same time, so I decided to do this. Also included in the price are two free checkups -- one this fall and another in the spring.

My new upstairs heat pump / air handler was installed the following Monday, and my downstairs AC / furnace was installed the next day. Work started around 7:30 AM each day and completed by 5 PM on Monday and 6:30 PM on Tuesday. The install was performed by Edgar and his assistant on both days. Edgar did a great job of explaining the installation process, and explaining how to use my new system after it was installed. I am extremely happy with the work performed by Edgar and his assistant - with their professionalism, knowledge, and quality. I would be pleased to welcome Edgar into my home again for other work.

The new upstairs heat pump, a 4-ton Carrier Infinity 18VS is awesome! It is able to run at 5 different speeds, automatically adjusting depending on how hot it is outside. It has kept my upstairs cool even on the hottest summer days -- a feat that my old heat pump could never accomplish. The new downstairs AC is a 4-ton Carrier Infinity 19VS, which has similar capabilities to the upstairs heat pump and works equally well. Features I enjoy include the ability to control both units from my iPhone, and that each unit reports the amount of energy it uses each day (averaging around $4 dollars a day total for both units in the July heat).

I am extremely pleased with Donmar -- with how they educated me when providing the quote, with the high quality work they performed during the install, and with the Carrier units they recommended to me. If you need to replace your AC / heat pump / furnace -- go with Donmar!

Let me start off by saying that I have been using DONMAR for the better part of 30 years to install and maintain my HVAC units in my home. And I would say they've been pretty solid over the years and I've been happy with their service overall.

Recently, I had DONMAR check on one of the two AC units in my house as it was not cooling like it should. My preference was to repair the unit as I have a well maintained, top of the line TRANE unit with a few years of life left in it.

The technician provided three estimates:
Repair: $2100 w/ 1 year warranty
More extensive Repair: $3800 w/ 2 year warranty
Replacement: $6700 w/ 10 year warranty

So like most situations where I'm faced with a large expenditure, I decided to get a second opinion. I had another company come out and provide me with their estimate, which I chose to do the repair work.

The other company fixed my unit for a total of $395. (parts and labor included)

I'm not sure if the DONMAR tech had a bad day, anticipated other parts breaking soon, or if he has an incentive to up sell, all I can tell you is I'm very happy to have saved a little money in the process of getting a second opinion.

Donmar is very good ... We had a very good experience from starting to ending . Michael who is the owners son was our point of contact . We did get multiple quotes . But Donmar's quote and their expertise was very competitive. I do not write reviews mostly. But these guys are awesome from the Top owner to the employees and they deserve 5 star review . They were very professional. Our decision was mostly based on our interaction with Michael . Though there is not much difference in pricing we decided to go with them solely bcz of Michael . Michael was very patient in answering all my questions and he is the only one who was willing to do manual J to calculate appropriate load . It's because of his time spent in explaining all my questions We decided to go with them . Bcz we were sure we will get good service from them . And we are hoping that he will be there whenever we ( HVAC ) need him .... Thank u Michael . Though we ran into issues with water heater .... Still they get 5 star review from me because of Michaels professionalism.

I just wanted to take a quick moment to praise your're service technician; Jorge Miranda who serviced our heating system this morning. Mr. Miranda arrived on-time and even had the courtesy of calling 15 minutes ahead to ensure we were ready for him. I knew Mr. Miranda was going to be exceptional, when he entered our home and immediately shook my hand and proceeded to put shoe covers on to ensure he did not bring dirt onto our carpets. Mr. Miranda thoroughly discussed what he was going to service today and approximately how long this would take. He then proceeded to service the units and kindly requested us to review his notes. Overall, Jorge Miranda was attentive, respectful and patient throughout our entire service. DONMAR is lucky to have such a friendly and professional service technician in Mr. Miranda. My family will be sure to use DONMAR HEATING & COOLING in the very near future.
