Donmar Co. Htg & Clg

We have used the services of the DonMar company for over 16 years. They have installed and maintained the heating and air conditioning equipment in both our home and that of our rental property. At all times the services have been on time and professional. Their technicians are knowledgeable and well trained. The installations were performed quickly. The surrounding areas were left clean and neat. There responses to telephone and email inquiries have demonstrated their interest in providing excellent customer service for their products more

Four years ago, I had Donmar install an extensive geothermal heating/cooling system in my home. Nothing was easy as we live in an old farmhouse but Donmar overcame every obstacle to give us a wonderful system. When the few to-be-expected glitches occurred, their service was exceptional. Everyone I've spoken with in the company from the annual service guys to the head of the organization, Don, have been a delight. My wife and I can't give a high enough recommendation for this company. more

When looking for an AC/Heating company to diagnose/repair/replace both my attic and first floor AC units, I searched for a local company that had a top rating. Through www.homeadvisor.com, I found Donmar to fit the bill. They came out immediately and diagnosed the problem within just a few short minutes and were able to provide multiple solutions to choose from. We scheduled an appt and they were able to replace the air handler unit in the attic and the evaporator coil downstairs in one visit. Javier and Edgar were very professional, friendly, informative, and efficient. Edgar went over the complete system with me offering advice for maintenance and what to look for to determine whether or not they are running efficiently and properly. They used drop cloths and foot covers while in the house and left it as clean as before they came. The pricing seemed fair given what every ac/heating company around northern VA charges, so the service was very important to us and they delivered. We would highly recommend Donmar for your AC/Heating needs, you won't be disappointed. more

We have been with DonMar for years. We trust their work and their service. We recently purchased a new heat pump from them. Installation was professional and so was the service. We have been using them for maintenance on our unit for years and will continue to use them for maintenance. They are honest and straightforward with their recommendations and always give us various options. They call to remind us when service is due which is a huge plus for busy working people. more

Description Of Work: Donmar replaced my heating and air conditioning system and built in humidifier with a new system by Carrier. Donmar had installed that system 15 years ago. This was a repeat call because their service back then was so good. They also installed a new system in an investment property a few years back. Member Comments: The estimate was handled promptly by the owner, communicated back and forth electronically so there was no need to meet in person. Donmar had the specifications for my home from the installation done 15 years ago. The team arrived promptly, covered their feet and the floors and set about taking out the old system, taking measurements for the new ductwork installation and from there installing the new equipment. I wish I could photograph the beautiful installation, it is just that beautiful. The Donmar team of installers arrived promptly at 7 a.m. and worked nonstop until 6:30 p.m. to get the new furnace, A/C and humidifier installed. This system has water warnings built in in two places and an electronic thermostat that does everything except cook breakfast (and it might have done that, but I didn't ask for that service.) This is the new Carrier Infinity System and it is quiet and lovely. It is suddenly 85 degrees outside and my home is fabulously comfortable. Let me tell you a little story about Donmar Heating: 15 years ago, Donmar was the only company that answered with a person on the end of the phone, on a late Saturday afternoon. My central air conditioning system failed and there was no getting it started, was time to replace. I had a longhair terrier at the time and he was a family member as were all of my pets including two mature cats. Donmar understood that my pets could not withstand summer heat for very long. So, I called on a Saturday afternoon, Donmar came out the NEXT DAY on Sunday and took measurements, and the next day, Monday, my new system was installed. Crisis over. I bought an extended warranty which was used only once but was beneficial pricewise, and only used several years after the original installation. With the "answering the phone with a human," and the emphathy for my pets, I knew I would call Donmar for HVAC installations which I have for my home, now with this installation, and for an investment property. The experience was the same at the investment property. My tenant was running "hot" systems and needed correction fast. Donmar came in with "military precision," waiting on the curb for my tenant to leave for work that morning.... Get the picture? This company knows Customer Service. Thank you Donmar!!! more

My technician, Paul, did an EXCELLENT job servicing my furnace! He called ahead of time to let me know he was on the way and showed up right on time! Finally a service company that shows up when they say they will!!! He did a comprehensive inspection and explained every step of the process to me. As an engineer, I understood the details of my heat exchanger, but was impressed with his ability to explain everything in a way that a novice could easily understand. I think that helps customers understand their HVAC needs and make decisions with more ease. Paul extensively cleaned my system with the most astute attention to detail! I was impressed! He even cleaned up after himself once the repair and cleaning of the system was complete! Not only was he great at his job, but he was courteous and nice to chat with as he did his work. I am thankful for Paul's service and HIGHLY RECOMMEND Donmar Company to anyone with an HVAC issue!!! I'm so impressed that I wrote this review minutes after my service was complete--it was that fantastic that it required immediate positive feedback! more

My wife and I were both impressed with DonMar. They were professional from every aspect including a thorough sales presentation, follow-up, prompt response to e-mails and calls, technical expertise and flawless installation with experienced qualified installers. We are very satisfied with how the install went and it was evident that these technicians were experts in their trade, worked efficiently and had every attention to detail. I have no hesitation in recommending them. As a matter of fact, if you're in the Ashburn area and need a replacement central air system, give Bill Blair at DonMar a call! more

TASK: Completely re-envisioning the HVAC and domestic hot water need of our 4K+ sqft home. The existing system used 2 small AC units and relied exclusively on a large hot water heater for domestic hot water and heating the entire home via attic and basement hot water (hydronic system). The 25 year old system was unable to keep up with the demands of a growing family, particularly on very warm and very cold days. PROCESS: I personally oversaw the process of identifying potential companies to do the work in question, working with them to ensure they met all the needs of the job, negotiating price, and eventually selecting the company to do the work. I sought estimates from 10 different HVAC businesses in northern Virginia and Maryland. Each one sent a representative to do an on-site evaluation of my home. Most of the representatives spent approximately one hour inspecting existing equipment and discussing my family's needs. Out of the 10, only 6 provided a plan and estimate for the job. Of those 6 two were poorly thought out and not feasible, even to my untrained review. That left four plans and estimates worthy of further consideration. Across the 4 estimates was an approximately 30 spread in overall cost. The average of the estimates was approximately $20,000. DONMAR APPROACH: 1- Comprehensive needs analysis: DONMAR was the only team that performed a formal Manual J Residential Load Calculation - a complicated and time-consuming analysis of home heating/cooling needs critical in establishing the real needs of a home. All the other HVAC reps were comfortable in eyeballing our needs or just assuming that they could extrapolate our needs from the home's current configuration and my complaints about its performance. 2- Intelligent, defendable planning: DONMAR submitted intelligent, well conceived plans that addressed the home's needs and my requests for future performance. They did not try to sell me equipment and excess capabilities I did not need and were honest in challenging me when i suggested equipment that was not indicated by their analysis and experience. 3- Continued engagement: DONMAR remained in periodic (but not annoying) contact with me as I spent the weeks necessary to review the several other estimates for work I had solicited. Along the way, as I learned more from my experience, I asked increasingly more targeted questions about their proposed system. To DONMAR's extreme credit, when it became clear that there was better equipment to employ, they readily reworked their proposal, but committed to keeping the cost to me exactly the same. 4- Technical excellence and customer-centered service: The installation went smoothly over three and a half days. The on-site boss spent a half hour with me each day going over plans for the installation, the impact on our cooling of the home and availability of hot water, and potential complications in the work. At one point it became clear that the installation of intake and exhaust pipes was going to potentially pose some serious technical problems. One fix would have required me to replace the doors of the basement closet where the gas hot water heater is located with louvered doors at my own expense. Another fix would have had DONMAR create an additional air intake vent from the closet into my wife's home office. Again, to DONMAR's credit, they spent an extra half day working out a code-complying fix that permitted the piping to run through the ceiling and paid for the repair of the cut out in the ceiling. How did the quality of the work compare to my expectations? Better in all respects than I had come to believe was likely. What reservations would I have in recommending them? None. In addition to their technical competence and professionalism, I give DONMAR high marks for sticking with me through the more than three months it took to definitively select them to perform the work. more

I needed an estimate and quick install. I got the estimate and the work was completed in the time mentioned. This was the second time I was using Donmar's services. I will recommend it to others as well. more

AFter getting several recomendations from a mother's group at Church we got qoutes to replace our system from 3 companys. We went with Donmar because not only were thier products and and priceing the best, but they also showed up on time, when they said they would. The install was done the same week and the installers were great! They spent alot of time teaching us how to use the new HVAC system. They also helped us with the rebate paperwork! I would recommend them everytime! more

This is the 2nd time I use DonMar to install a brand new unit. First was a Heatpump at my old Townhouse and now a full efficient Trane XL20. I am very happy with the new unit. I can feel the difference between the old and the new unit. I will recommend this company to anyone that wants to replace your HVAC system. more

Everyone I have met from the Donmar company where very professional - Sales person and installation team. I recieved a fantastic price on the system I wanted! They beet the other Carrier bid by thousands! Installation team was great - On Time, finished ahead of schedule and was very professional and helpful explaining everything. more

Our 10 year old through the wall Carrier unit died. We called Donmar, who looked at the unit, determined that it was dead, took measurements, and promised to get back to us. Nothing for two days, we called Donmar and was told that they had two calls into companies that handle the ac unit we needed but hadn't been called back. Two more days went by. Nothing. We called again and were told that Donmar had still hear nothing new. It was over 100 degrees! Call Donmar only if you want to lose weight sweating in 100 degree heat waiting (in vain) to hear from them. $79 wasted. more

Donmar Company was very good to work with. They offered a good price and did good work. Also, installation was done on the very next day. The installation team was very professional. Came on time, did good work and explained everything before they left. Highly recommended. more

Salesman, Bill Blair was friendly, helpful, knowledgeable, and not pushy. The two techs who did the installation were clean-cut, polite, respectful, informative, unobtrusive, and focused. All very professional. more

I have been using Donmar for over ten years. I have and would recommend them to anybody who need air condition service or who need an air condition replacement. more

I would recommend Donmar for Heating and AC installations. more

We really appreciate the efforts by the sales representative in providing the data needed to make the right decision and working with us to come with a workable price. The installation team did an outstanding job, the system was installed as promised. The team took the time to explain the operation and they left the work area as clean as they found it (maybe better!). Thanks to DonMar. more

After researching and interviewing several HVAC companies in my area for a complete HVAC system replacement I decided to select Donmar Company. From my very first conversation with the sales rep I felt like I had finally contacted and knowledgeable and trust worthy company. Instead of trying to push HVAC systems out of date and unreliable like other companies I interviewed I was presented with several intelligent choices and pricing to fit our home and needs. The installation of the system I chose was very professional, clean and educational. The technicians were passionate about their profession and very enjoyable. Donmar Company defines customer service excellence to a higher level and sets the bar to a high level that other companies cannot seem to achieve. Thank you very much to everyone at Donmar Company, we are truly happy more

Donmar installed a new Trane system for my townhouse. Entire experience was great, the installers did a great job, very thorough. Took the extra time to really tidy up after the job so it looked like no one was ever here. System works great and now I am not worried about the hot summer ahead. Thanks guys more
