HVAC reviews in Chantilly, Virginia

This is the worst AC company I have ever come across. They have not been able to fix our ac for almost a year now. Every time they come they say everything is fixed, after two weeks the AC stops cooling. Today they came and promised they have fixed it and now our ac is not working at all. Do not work with this company. They will constantly screw your system and they have no clue what's going on. They have the worst customer service

They were able to schedule a convenient appointment, they arrived as expected, did furnace inspection and all was at the price they quoted. Imagine a service provider showing up when they say they are going to, do what they say they are going to do and for how much they say they were going to do!!

If you have an A/C or Heating problem you should call Residential Systems. They were extremely pleasant on the phone and took care of my issues very quickly. All the technicians were very pleasant and helpful explaining what was wrong and what they did.

This contractor is HORRIBLE and unresponsive. They have a contract with warranty companies and they never call to setup appointment. Warranty companies need to terminate their contract with these clowns and find a better company. We can make this happen, if more people complain. RSI, GET YOUR ACT TOGETHER!

Great experience. Warranty company sent them out so we expected the worst but the service and professionalism was stellar. Of course they did what the warranty company made them do ,the absolute minimum, but at least we knew it was done right. We will keep them in mind for our next service even when we cancel our home warranty

We have this service call placed and they did not call and did not answer my calls. They called to schedule after the HW company follow up and set up 4 hour wait window. Indeed they don't value customer, customer time and urgency of the issue. There is no heat and its winter time. Definitely the warranty company should drop them from their contractor list.

This company is absolutely awful. RSI charged my mom for a coil and a TXV valve for her indoor air handler at the same time they installed a new heat pump. Come to find out they did not install the coil and TXV valve that she paid for. The heat pump they sold her was not compatible with her indoor air handler. They refused to answer her calls for weeks and will not remedy their mistake. She has had to replace the entire system.

This company must never have a customer service person working at their store because they never ever pick up the phone. If you make a claim through your warranty company good luck in getting these guys to call you and make an appointment. You have to call and call them to get them to come out and continually follow up otherwise they will never show up. If you are able to get them to show up they actually get the work done for the most part.

The experience I had with Residential Systems was just fantastic. The A/C tech "Chris" who came out and did the work was very professional, friendly and just very approachable whenever I had a question. You could really tell he knew what he was doing analyzing and working on our non- functioning condenser issue.This was not a simple fix on a failed unit but Chris performed the work in an efficient manor with a step-by-step diagnosis of our failed condenser. He basically got the cool air flowing in the house again with the condenser fan running. At the end of the day, which I didn't consider that long and well worth the reasonable price. I would highly recommend anyone in need of Heating and A/C work, to use them.

There aren't too many honest and hard working A/C contractors out there these days, so it was very refreshing working with Residential Systems. Thank you for your prompt, courteous and thorough service.

I was able to create an appointment for the next day. Terry was able to assess the issue quickly and get a motor within 30 min. We had a cool house in no time and for about what I expected to spend on the job. Overall very satisfied.

I had a broken HVAC system and contacted my home warranty company. They provided one contractor who came out and was unable to fix my unit, so my warranty company contacted Residential Systems. They asked for my credit card up front, without even diagnosing the problem or providing me an estimate for the work to be done (which in hindsight, I should never give out my cc #) They wouldn't even come out to my home until they had this. It was to cover the $100 deductible as required by my warranty company. They came out (a week after the initial call), and my credit card was charged that day. They could not perform the work that day because they did not have the part. They called the warranty company back and 'lied' to them and said they did not have access to the unit and I needed to pay an additional $65 for them to come back out since they could not repair the unit that day. They did not even mention to them that they did not have the part for the repair on that day. They claimed they had to access the unit through the drywall, which is totally untrue since I've had the same unit worked on in a different condo in the same building, and you did not have to access through the drywall. This is a classic bait and switch operation. They charge me $100 for work not performed, which was a "DEDUCTIBLE" (even says deductible on my receipt) and then try to charge another $65 to come back out. After numerous calls and left voicemails (they would not answer the phone), they finally contacted me back and said they would not refund the $100 even though it was a deductible and they did not perform any work at all. Mark, who I believe is one of the managers, was very unprofessional on the phone. I was even laughed at on the phone by the receptionist, Michelle. VERY unprofessional and unethical practices of any business.

I highly recommend against using Residential Systems Inc. Their technician gave me misleading information about my system, including telling me the blower wheel was defective when it was not.

Their dispatcher then told me they would not repair my system (which just needed a blower motor) unless I also hired them to replace the blower wheel and replace the ducting leading from the unit due to "liability issues" (at an additional cost or $800). The markup on the parts they quoted me was more than the total cost of having another company come out and complete the job.

After having another company come out, it turns out that not only was the blower wheel not defective, but the duct work was up to code too.

This company seems to me to be very dishonest. They were, however, happy to cash the check for the service call.

In Oct, RSI inspected my 85-year-old mom’s furnace and claimed that it leaked CO, that could cost up to 20k to repair and turned off her heat.
When I discovered this, I asked RSI to restore her heat and they claimed that “by law” they could not. I could not understand why they would leave an elderly woman without heat, especially since ventless systems produce considerably more CO in a home than the system she had. I also knew there was no way a new system would be 20k. After explaining this Mark at RSI still refused to restore her heat. RSI was also unable to provide the CO reading that they claimed caused them to cut her heat. When I told him I needed the issue escalated he refused to give me the owner’s contact info. RSI created a needless hassle and serious issue for my mother - I purchased a CO meter and it measured "0" in multiple places.

This company was forced on me by my home warranty. It took weeks to get someone out to look at the unit and then several additional weeks to get the unit repaired. Less than a year later (and after my home warranty expired) the unit was again not operational and they did not have any workmanship guarantee and told me I was out of luck. The company that I got to replace the unit out of my own pocket found cut wires and the unit in overall poor condition from the previous work that was done on it.

My experience with RSI was not that of all these "one-star" folks. My AC went out Friday night, I made the claim with my home warranty company (2-10 HBW) on Saturday morning (early) and I received a call to set the appointment two hours later for Monday between 10 am and 2 pm. The technician arrived at 10:45 am, right within the range. It turned out to be a simple fix of adding more freon to charge the system (low refrigerant levels = the A-coil in the furnace freezing up and blocking air flow). RSI knows their business and my technician was the "most recent hire" - 7 years ago! I'm grateful for this experience having read several negative reviews. For what it's worth. I hope your experience is as mine was.

This company is amazing! I would recommend them to anyone and we will use them in the future. Both technicians that were sent out were fantastic! After we bought our home we started having issues with are AC/heating system and the first company that came out never fixed the problem, after 5 times. We were so frustrated and upset about it, but this company made everything so easy. Residential Systems INC fixed the problem right away and had wonderful customer service.

Disappointed with their customer service and with the quality of workmanship when the technician checked our hvac system. He left the work area very messy. Also, making contact by phone is very difficult. While the technician was at our home, he attempted to call back to the office for information and even he couldn't get in touch with anyone for answers. I'm thankful we didn't have to pay for their services, it was a carry-over contract for a system inspection from the previous owners. Rather than gaining a new customer, they lost one by the poor service they provided. I would not recommend them.

I used this company several times for HVAC issues thru 2-10, never had any problems. most recent service was last Friday, the technician showed up at the beginning of the appointment window, very friendly and knowledgeable. fixed issue right away. getting appointment set up was also easy - Mark called me the day after I submitted the online request. will use it again.

They never called me to set up my work order, which was placed through my home warranty. I called and left a message and they didn't call me back. When I finally got ahold of them it was a week later (which is no fun when your ac doesn't work). They scheduled a technician to come to my house and when that day came, no one ever showed up. I called them throughout the day to see what happened and no one ever answered the phone or called me back to respond to the messages I left. I'm not sure how they are considered a legitimate business.

I made a claim on Monday morning with my home warranty company (2-10), and RSI called me within an hour and scheduled service for the next day. I was impressed with their promptness! The technician was friendly and knowledgeable. He diagnosed the issue quickly and was out in less than an hour. I am very pleased with his service!

The only reason I bumped the rating down is due to the receptionist. Frankly, she was rude. My appointment timeframe was 12p-4p. The tech arrived early at 11am, and I wasn't home. The receptionist called me, argued the timeframe window and literally huffed at me through the phone. If this had been my only interaction with the company, the rating would have been incredibly lower.

Over the last 7 years in our home, I have called in 3 ac service calls through 2-10 home buyers warranty. By far this was the smoothest and best service call.

I noticed my indoor unit making an unusual rattling, buzzing noise. Requested a service call through 2-10 home warranty. Did have to wait a week for the appointment, but was worth it. Mark called when Rick, the technician was on the way. Showed up as promised. Diagnosed the issue, answered my questions, ordered and replaced parts the same day. Indoor unit back to normal.

I feel most people are calling because their ac is completely not working and of course, on the hottest time of the year. They are already mad and frustrated as it is and when an ac company is called upon and the company is not able to accommodate and address the situation immediately, they get a bad review. You are not the only one with a malfunctioning system. Give the service guys a break, they are hot too. I would definitely request to have RSI come again. Thank you Mark and Rick!
